In the paleontologic world the location and availability of pertinent collections of fossils and related Recent material is imperative to refined studies. Par- ticularly important in such research are the specimens of original descriptions, the so-called type specimens of species. Much time and energy may be spent in searching for their existence and perhaps complicated history. A useful tool for workers is a published cata- logue of type material in specific institutions. To this end the Paleontological Research Institution has been ever conscious of that important service. In 1960 the Catalogue of the Type and Figured Specimens of the Paleontological Research Institution was published in Bulletins of American Paleontology, volume 40, Num- ber 184, 996 pages. Since that time additional types have been de- posited in the institution. To bring the supplementary information up to date the present catalogue has been compiled by Stephen J. Fast. He has done an efficient conscientious performance by critical- ly checking the specimens with the original published data or related information. The cataloguing of the specimens was performed by Mrs. Dora Hurd. The funds for the preparation of this catalogue by Stephen Fast for the Paleontological Research Institution was made possible by a grant in 1976 from the United States Steel Foundation, In- corporated, of Pittsburgh, Pennsylvania. The Paleontological Re- search Institution is grateful to that corporation and members of the board for making possible the compilation of this important, useful compendium. A contribution from the Amoco Foundation, Inc., in 1976, pro- vided financial aid toward the publication of the catalogue. The Paleontological Research Institution appreciates the help of the Amoco Foundation, Inc. and the directors in furthering this aid to scientific advancements. February 1, 1978 Katherine V. W.

Brann and Lois S. Kent, and published as Bulletin of American Paleontology, volume 40, Number 184, 1960. The format of the Brann and Kent catalogue is followed, ex- cept in several minor ways. In most cases, for the sake of brevity, specimens from one locality are lumped under one reference. The locality descriptions are generally brief where such localities are specifically described in an author’s cited publication. Specific name changes that have come to my attention are noted. Also in most cases, scientific names, formations, and ages are listed as originally published by an author, except where that author subsequently made corrections or reinterpretations. In this regard, the ages listed for most specimens should be accepted with the usual scientific cau- tion. Some corrections were made for misspellings, word endings, and the like. In 1971, Cornell University donated some type collections and other miscellaneous type specimens to the Paleontological Research Institution. The main collections were those of Dr. C. J. Maury °(1912) from Trinidad and from Santo Domingo (Dominican Re- public) (1917), including type specimens from the William M. Gabb Collection at Cornell, originally deposited there in the late 1800’s. Also included were some plastotypes made from specimens in the Brazilian collection of Maury, Servico Geologico e Mineralo- logico do Brasil, Monographia IV, 1925. In 1977, Cornell further donated Maury’s duplicate material from Trinidad and Santo Domingo to the Paleontological Research Institution. While exam- ining this duplicate collection, I found that the Gabb Collection of metatypes mentioned by Maury (1917) had been incorporated by Maury into her collection. Dr. Maury figured many of Gabb’s specimens and in several cases did not mention that the specimen was Gabb’s. As far as I was able, I have noted in this supplement the Gabb material. The localities given to Maury’s Santo Domingo 8 BuLLetTiIn 302 type specimens in the Cornell Catalogue are questionable, according to the following note in that catalogue: “First locality listed in Bull. Am. Pal., v. 5, No. 29 has been taken to be that from which figured shell came. This assumption may be incorrect.” The Paleontological Research Institution also received from Cornell in 1971 a suite of Devonian fossils figured by G. D. Harris in Elementary Natural History Series, Number 2, 1899. The plates of this ancient pamphlet were reproduced and the scientific names revised by K. V. W. Palmer and D. C. Brann in “Illustrations of Fossils of the Ithaca Area,” 1966, available from the Paleontological Research Institution. The original material which was the basis of the Edward Kin- dle, Ph.D. thesis, “The Relation of the Fauna of the Ithaca Group to the Faunas of the Portage and Chemung” [Upper Devonian], Bulletin of American Paleontology, volume 2, Number 6, 1896, was donated to the Paleontological Research Institution by Cornell Uni- versity (1971). Those specimens remain on the original mounts, with the corresponding station numbers and specific identifications as made by Kindle and published in his thesis. This material is exten- sive and valuable because of its stratigraphic sequences and because many of the early localities are not now available.

The speci- men in question is listed in this supplement as a hypotype, but according to Jung, it is a “virtual topotype” as he feels his speci- men was collected from the same place as Hodson’s locality 2207. Hodson’s description of his locality 2207 is vague and imprecise. *Again, unlike the Brann & Kent catalogue, the asterisk refers to a locality in Maury’s paper on Santo Domingo, B.A.P., v. 5, No. 29, 1917. It means that the locality given here was determined from an original label in Maury’s duplicate Santo Domingo Collection. That label contained (a) the particular species name, (b) a locality, and (c) the word “Figure” in Maury’s handwriting. The age of lower Eocene given to the Soldado Formation in Maury, P. R. I.

ABSTRACT The Arcturus Group, early Permian, of eastern Nevada and western Utah contains the Riepe Spring Formation at the base, Riepetown Formation, Pequop Formation, and Loray Formation at the top, and ranges in thickness from less than 1000 meters to greater than 2000 meters. The base of the Arcturus Group is early Wolfcampian in the western and northern parts of the area, and middle Wolfcampian in the center of the depositional area. Deposition of sedi- ments continued without significant interruption until the late Leonardian. The Leonardian-Guadalupian boundary occurs in the overlying Kaibab Formation. Normal salinity marine biotas are common throughout, and biotas repre- senting hypersaline environments are present in the upper part of the Arcturus Group. Biotas representing hyposaline (brackish) and fresh-water environments are not recognized and are probably absent. Arcturus Group biotas are dominated by brachiopods and molluscs. Brachio- pod diversity and abundances are low, except for the genera Squamaria, Cos- tellarina, and Composita. The small productacean Costellarina is common in shallow-water molluscan-dominated biotas and is the most common brachiopod in the Arcturus. PE cans described as new are Costellarina kaasai, n. sp., Costellarina plasi, n. sp., Costellarina carlstroemi, n. sp., and Wilberrya fra- gilis, n. gen. and n. sp. The Costellarininae are transferred from the Strophalo- siacea to the Productacea (Linoproductidae) on the basis of new information on the type genus Costellarina. Mollusc diversity and abundance are high in almost all biotas. Scaphopods, rostroconchs, and bivalves of the superfamilies Ctenodontacea, Nuculanacea, Arcacea, Pinnacea, and Ambonychiacea are described in this part of the study. Molluscan taxa designated as new are the bivalves, Quadratonucula stella, n. sp., Polidevcia arctura, n. sp., and Girtyana stellara, n. sp., and Meckopinna, n. gen. INTRODUCTION In the eastern part of the state of Nevada there is a nearly complete stratigraphic section through most of the Permian System, recording continuous deposition from the base of the Wolfcampian Series up through most of the Guadalupian Series. It is the most complete stratigraphic sequence of Permian strata in North America outside the classic west Texas section and is richly fossiliferous in most parts of the sequence. The Nevada Permian biotas have a different aspect from the Texas biotas, having closer affinities to Permian biotas in the remainder of the Basin and Range Province, and the Colorado Plateau and Rocky Mountain regions. These 258 BULLETIN 303 areas contain other good lower Permian sequences, especially southern Nevada, southern Arizona, and Idaho-Utah-Wyoming, but only in eastern Nevada is the section continued up into a thick sequence of fossilferous upper Permian strata. The Nevada Permian biotas belong in a different biotic province from the tropical Texas Permian (Yancey, 1975), and most species appear to have longer time ranges than comparable species in Texas sections. The lower Permian section in eastern Nevada contains common or abundant fusulinids, brachiopods, bivalves, and gastropods, and less common ammonites and corals. The fusulinids offer the greatest potential for correlation, and these have been described in publica- tions by Knight (1956), Berge (1960), Slade (1961), Robinson (1961), Brill (1963), Bissell (1964), Stevens (1965), and Douglass (1975), which provide a good analysis of the lower Permian fusu- linid biostratigraphy. Ammonoid faunas are present in parts of the Arcturus Group, but these need further description and study be- fore they can be used for biostratigraphy. Corals have been studied from the Arcturus Group (Wilson and Langenheim, 1962; Stevens, 1967) and have been found to be useful for correlation, but their paleoecologic restrictions were similar to the fusulinids, and they tend to have similar distribution patterns. The brachiopods are poorly known, but they promise to be biostratigraphically useful due to the accumulating monographic knowledge of Permian brachio- pods in the Texas area. Bivalves and gastropods are the most abun- dant and diverse fossils, but they have only been briefly described by Mayou (1967), Yancey (1969), and Yochelson and Fraser (1973), so the biostratigraphic potential of these groups has not yet been realized despite their abundance throughout the Permian. Previous work on the Permian stratigraphy of eastern Nevada is scattered through a number of studies on the general stratigraphy or structure of the region, with a smaller number of studies being confined predominantly to either the Permian or to the structural basin centered in White Pine County, Nevada. The more relevant of the early publications were the reports on the paleontology of the Eureka district by Walcott (1884) and the report on the geology of the Robinson mining district (at Ely) by Lawson (1906). Wal- cott extensively investigated the Carboniferous deposits of the Eureka area and touched on the Permian. Lawson provided the first stratigraphic study of the Permian rocks of the region.

Collecting sites were selected to obtain the most complete stratigraphic sections over the geographic extent of the Arcturus Group and to include the most fossiliferous sequences. A greater number of sections are located in the central and northern areas where exposures are more favorable and where rapid facies changes occur. The collection sites are all within a large region centered on the town of Ely, Nevada, in White Pine County. Collections of fossils were made from all stratigraphic horizons within the Arcturus Group except the Riepe Spring Formation. Fos- sil collections through the post-Riepe Spring portions of the group were made on stratigraphic sections at 11 sites. Three of these, in western White Pine County, were made by Calvin Stevens of Cali- fornia State University, San Jose, who graciously allowed the loan of those collections. The stratigraphic sections in western White Pine County are in a different facies of the Arcturus Group and contain a different biota from the eastern facies.

PERMIAN BRACHIOPODS AND Mo.iuscs: YANCEY 261 PALEOENVIRONMENTS Paleoenvironments of the Arcturus Group sediments are similar throughout the group but are complex in local detail. The Arcturus Group was probably deposited entirely within about 200 meters of sea level, and most of the sediments were deposited under marine conditions. The total thickness of sediments deposited varies regionally from 1000 meters to greater than 2000 meters. Through most of the Arcturus Group there is a trend of eastward-increasing grain size in the sediments, reflecting an eastward increase in bot- tom energy conditions and a probable eastern sediment source. This sediment source was active throughout the deposition of the Arcturus Group and resulted in deltaic infilling of the basin, with the areas of thickest sediment accumulation in the center of the basin. During at least part of this time the Hamilton Basin was a topographic high projecting westward from a more persistent high area in west-central Utah (Zabriskie, 1970; Stevens, 1973; Marcantel, 1975). Marine waters occasionally covered it, but did not cover the Utah high area or the highs on the Antler Orogenic Belt during the early Permian. A marine transgression into the center of the Hamilton Basin in early and middle Wolfcampian time over an unconformable sur- face (Dott, 1955; Bissell, 1964; Zabriskie, 1970) started from deeper areas to the north, and perhaps the west and south. During this time water depth increased towards the north, and perhaps the west and south. During the remainder of the Wolfcampian and the Leo- nardian, environments were locally complex and variable, but gen- erally similar throughout the Arcturus Group with the exception of the highest stratigraphic horizons. Deposition was everywhere near sea level and shorelines undoubtedly fluctuated greatly. The greatest environmental differences were the facies changes from predomin- antly terrigenous deposition in the eastern and western parts of the Arcturus Group area to predominantly calcareous deposition in the northern areas. There were some topographic lows in the western areas, which were probably never deeper than 100-200 meters. An eastward-thickening unit at the top of the Arcturus contains abun- dant evaporite sediments and is probably time transgressive. During the late Leonardian (upper part of the Arcturus Group) hypersaline environments were common in the eastern areas, while more normal 262 BuLLeTIN 303 marine environments predominated elsewhere. Environmental patterns were complex across the Hamilton Basin throughout the time of deposition. The basin contained many different environments which were inhabited by distinct biotic com- munities (Yancey and Stevens, 1971). There is no evidence of any brackish or freshwater deposition, but hypersaline and normal marine environments are fully represented. The reconstructions of the Arcturus Group environments in Text-figure 2 show probable spatial relations of environments within the Hamilton Basin at three arbitrary levels within the Arcturus Group. PALEOCLIMATOLOGY The paleoclimatic conditions of the Nevada area during the Permian can be deduced from lithologic and biologic data and give evidence of both the average paleotemperatures and paleorainfall conditions. In addition, it is assumed from regional stratigraphic and geologic relationships that the ocean areas were bordered on the east by a wide, low coastal plain that must have had a strong influence on the local climate. The average paleorainfall can be determined from the lithologic character of both the marine and nonmarine strata of Permian age and the marginal marine biotas. Within the Arcturus Group there are fairly extensive deposits of evaporites (Hose and Repenning, 1959; Steele, 1960) and associated sediments containing algal stromatolites and shrinkage cracks, especially in the upper part of the Arcturus. During the present study it was also found that hyper- salinity was common in marginal marine environments and that these environments support distinctive biotic communities, but that hyposaline or brackish water environments are completely lacking. These factors indicate a persistent dry climate probably of wide- spread extent during the interval of time represented by the Arcturus deposits. During the same interval of time, red beds, cross-bedded sand- stones, and lesser amounts of evaporites are common and extensive in the western states and are usually interpreted to be indicators of dry climates. Brill (1963) showed the interfingering of Arcturus strata with strata on the Colorado Plateau which are usually inter- preted to be desert deposits (Coconino-type sandstones — Poole, 1964). The Arcturus Group was deposited in a dry area that ex- PERMIAN BrAcHIOPODS AND Mo.tiuscs: YANCEY 263 Siltstones with subordinate shales UPPER WOLFCAMPIAN LOWER LEONARDIAN — _ Shales _— 7 SHALES with minor carbonates SILTSTONES SANDSTONES PREDOMINATELY CARBONATES EVAPORITE — BEARING STRATA UPPER LEONARDIAN Text-figure 2.

Evaporite deposition over this entire area was commonest during the Leonard- ian, indicating that that portion of the North American continent was located in the middle latitudes. By comparison with modern climatic zones, it is clear that dry climates are the rule along the western edge of the American continents outside of the equatorial or the cold temperate to arctic zones. BULLETIN 303 264 /~ Li aa / all / be DIAN GRAN PROVINCE ~ PERMIAN BRACHIOPODS AND Mo.tiuscs: YANCEY 265 Paleotemperature determinations by the oxygen isotope method have not been attempted, but the relative position on the Permian climatic-temperature gradient can be determined. Stehli (1964, 1971) and Rudwick and Cowen (1967) clearly demonstrated that Permian biotas were temperature controlled, similar to modern biotas, and that both a temperature gradient and a biotic diversity gradient existed during the Permian. In a traverse from the U.S.- Mexico border to the Arctic Ocean, Permian biotic diversity regu- larly decreases to the north. Three biotic provinces can be distin- guished along this trend (Yancey, 1975). In the southern areas there is evidence of tropical temperatures with the common occur- rence of large reefs and highly specialized and highly ornamented taxa. In the northern areas there is evidence of polar temperatures and glaciomarine sediments (Text-fig. 3). During the Permian the North American continental block was located mostly or entirely in the Northern Hemisphere (Smith, Briden, and Drewry, 1973) and covered an area from the paleo-equator to near the rotational pole. The Arcturus biotas have intermediate diversity, lack the specialized genera characteristic of the tropical and arctic areas, and occupy the middle of the three North American biotic provinces. From both biotic and lithologic evidence, this is considered to be a temperate climatic province. Worldwide evidence supports the model of bipolar glaciations separated by temperate zones and an equatorial belt during the Permian, and the climates must have been similar to modern climates. The Arcturus biotas occur in the southern part of the Permian Northern Hemisphere temperate zone and probably had paleotemperatures similar to modern warm temperate climates. TECTONIC SETTING The Arcturus Group occurs within a wide north-south trending belt containing thick deposits of Carboniferous and Permian age in eastern Nevada and western Utah. Roberts and others (1965) identified this as a miogeosynclinal belt during the Paleozoic and most of the Triassic. It is bordered on the east by cratonal areas with high ancestral mountain ranges, and on the west by a belt Text-figure 3. Permian biotic provinces of North America (from Yancey, 119/7/5))e 266 BULLETIN 303 containing siliceous and volcanic rocks of eugeosynclinal or ocean basin type. These tectonic belts extended along the western edge of the North American continental block, and Speed (1971), Silberling (1973), and Rogers and others (1974) identified the western edge of the miogeosynclinal belt as the margin of the continental block during the Permian and Triassic time. On the miogeosyncline, sediments accumulated in many loosely connected, irregularly subsiding basins interspersed with local highs (Brill, 1963; Stevens, 1965), such as the Oquirrh Basin in Utah and the Bird Spring Basin in southern Nevada. The Arcturus Group was deposited in a broad subsiding area called the Ely Basin by Bis- sell (1962), the Hamilton Basin by Brill (1963), the Butte Basin by Stevens (1965), and the Arcturus Basin by Zabriskie (1970). This single tectonic feature has such an extraordinary diversity of names only because its geographic and time limits are inadequately known. Ely and Arcturus are stratigraphic names that apply to units which are not coextensive with the basin. Hamilton Basin has priority over Butte, and is used here. The Hamilton Basin is centered on White Pine County in Nevada and extends from the highs of the Antler Orogenic Belt (Manhattan Geanticline) on the west to a high area called the West Central Utah Highland (Steele, 1960; Bissell, 1962; Zabriskie, 1970) on the east, and about an equal distance north and south where the boundaries are not so well-defined. Most of the boundaries occur where the stratigraphic record has been lost. The northern boundary (Northeast Nevada Highland) and southeast boundary (West Central Utah Highland) are believed to have been high areas during the Permian, but this needs further verification. The basin is most distinct during the lower Permian and may persist into the upper Permian, but post-Permian erosion has removed so much of the record in the southern part of the basin that its temporal existence cannot be determined. Formational units extend widely across the basin suggesting a similar tectonic history in most parts of the area. To the west the Antler Orogenic Belt (or Manhattan Geanticline) was a site of uplift and thrusting and a source of sedi- ment that was shed into the adjacent low areas of the basin. The West-central Utah Highlands were not a significant source of sedi- ment although a major source of sediment for the Hamilton Basin PERMIAN BrRaAcHIOPODS AND Mo.tiuscs: YANCEY 267 probably was to the east or southeast. At the beginning of the Permian the center of the Hamilton Basin was high relative to adjacent areas to the north and west. Marine waters transgressed over the high parts by mid-Wolfcampian time. The basin subsided continuously through the lower Permian, with the thickest deposits accumulating in the center of the basin (especially in the Butte Mountains area). STRATIGRAPHY OF THE ARCTURUS GROUP The Arcturus Group is a thick stratigraphic unit, ranging from less than 1000 meters to more than 2000 meters in thickness which includes most lower Permian deposits. Its lower contact occurs either at the system boundary between the Carboniferous and Permian, in a conformable sequence in the northern and western parts of the basin, or at an unconformity at the base of the Permian in other parts of the basin. This unconformity is widespread in cen- tral eastern Nevada and adjacent areas (Bissell, 1964; Barosh, 1968; Zabriskie, 1970). In most areas it represents a time gap of most of the Missourian and Virgilian and the early Wolfcampian. The upper contact occurs at a major, sharp lithologic change from fine-grained terrigenous clastics with evaporites to massive limestones of the Kaibab Formation, the lowest unit of the Park City Group in the region. The Arcturus Group is a mixed terrigenous and carbonate sedi- mentary sequence containing much more terrigenous clastic (as well as evaporite) rock than underlying and overlying sequences (Ely Group below and Park City Group above). It contains the deposits of a single major cycle of sedimentation, and contains well-defined smaller cycles of sedimentation that may in part be generated by fluctuating sea levels. The entire Arcturus Group appears to be a transgressive-regressive sequence; from a thin transgressive phase of pure carbonate deposition at the base, changing to a thick regressive sequence of more terrigenous clastic strata, and culminating in evaporite-rich strata at the top. The Arcturus Group ranges in age from early Wolfcampian to late Leonardian, and possibly early Guadalupian. Age determinations are available principally from carbonate units deposited in normal marine environments. The basal transgression (Riepe Spring Forma- 268 BuLLETIN 303 tion) was completed over the center of the basin in mid-Wolf- campian time. Deposition of the Arcturus Group was terminated by the widespread transgressional deposition of carbonate of the over- lying Kaibab Formation. The contact between the Arcturus and Kaibab is an approximately isochronous horizon formed by the flooding of the restricted, evaporitic Loray deposits. Dating of the Kaibab transgression has proved difficult. The best available deter- mination correlates the Kaibab of the Hamilton Basin with the type Kaibab which is dated variously as upper Leonardian or lowermost Guadalupian. Formations within the Arcturus are poorly determined, but there is some uniformity in usage. The Arcturus Group was pro- posed to include the sequence of Permian units underlying the Kaibab Formation in the vicinity of Ely, Nevada. This sequence includes a basal carbonate unit, a lower sandstone unit, a middle carbonate unit, and a top evaporite-bearing unit. This sequence is typical of the central part of the Hamilton Basin and is exposed along the length of the Egan Range and Butte Mountains in White Pine County, Nevada. Units in this succession have been given the names Riepe Spring Formation, Riepetown Formation, Pequop Formation, and Loray Formation (oldest to youngest respectively ) by Steele (1960). The Riepe Spring Formation and Riepetown Formation have type sections in the Egan Range near Ely, but the Pequop Formation and Loray Formation have type sections in Elko County, Nevada. As stated by Yochelson and Fraser (1973), there are problems in applying these names beyond their type areas. The two upper units have been the subject of much nomenclatural de- bate, and many workers have referred to them as lower Arcturus Formation and upper Arcturus Formation, but they are valid formational units satisfying the criteria of distinct lithology and mappability. In the northern part of the basin (Elko County, Nevada; Tooele County, Utah) carbonate sediments are predominant throughout the sequence. Formations are different from the central part of the basin, with the Ferguson Mountain Formation at the base, the type Pequop Formation overlying this, and a more ter- rigenous Loray (?) Formation of variable thickness at the top. In the western part of the basin there are rapid facies changes PERMIAN BracHiopops AND Mo.iuscs: YANCEY 269 with fine-grained sediments (calcareous siltstones, marls, and silty limestones) predominating in the zone between the center of the basin and basin edge. Coarser-grained sediments with conspicuous chert pebbles and chert conglomerates predominate further west in Eureka County, Nevada. The sequence in the western part of the basin is divided into two formations, a lower unit of mostly car- bonate with minor chert sands and conglomerate named the Carbon Ridge Formation, and an upper unit containing conspicuous chert conglomerates and other lithologies, the Garden Valley Formation (Nolan and others, 1956). The Carbon Ridge Formation is the ap- proximate equivalent of the Riepe Spring Formation and Riepetown Formation, and the Garden Valley Formation is the approximate equivalent of the upper formations of the Arcturus Group (Barosh, 1964, unpub. Ph. D. thesis, Univ. Colorado). In the area between the western edge and central part of the Hamilton Basin, massive calcareous siltstone lithologies are common. Barosh noted that they are a transitional facies between the western conglomeratic and cen- tral typical parts of the Arcturus Group, and Stevens (1965) re- ferred to them as the “Dry Mountain lithosome” (for exposures at Dry Mountain in White Pine County, Nevada). They appear to be a valid formational unit and are of special interest because they characteristically contain ammonites. In the Maverick Springs Range calcareous siltstones are present in the stratigraphic context of the central basin sequence, where they underlie massive car- bonates of the Pequop Formation and are of late Wolfcampian and possibly early Leonardian age. In the eastern part of the basin the Riepe Spring Formation is present (Barosh, 1968), but the other formations of the Arcturus cannot be distinguished. The post-Riepe Spring portion of the group is designated simply as the Arcturus Formation. The interval here referred to as Arcturus Formation is not lithologically equivalent to and is only partly time equivalent to the interval in the central basin area (Pequop and Loray units) called Arcturus Formation by vari- ous authors. Coarse-grained sediments predominate in all but the lowest parts of the sequence and sandstones are common. The area is transitional to the Colorado Plateau area which has thick quartzose sandstones of Early Permian age (Brill, 1963). Cross sections showing the formational interrelationships are 270 BULLETIN 303 given in Text-figure 4. A comprehensive and detailed analysis of lower Permian formational relationships east-west across the Hamil- ton Basin is given in Barosh (1964, unpub. Ph. D. thesis, Univ. Colorado).

Riepe Spring Formation: This formation consists mostly of massive limestones and forms a thin carbonate cover on top of the unconformable surface eroded in late Carboniferous and earliest PERMIAN Bracuiopops AND Mo.iuscs: YANCEY 271 Permian time. This unconformity occurs within a sequence of mas- sive limestones and does not correspond with a major change in lithology. The Riepe Spring Formation is less than 200 meters in thickness and is thin in proportion to the remainder of the Arcturus Group. It has been given a Wolfcampian age by Wilson and Langen- heim (1962) and Bissell (1964) and is probably middle Wolf- campian in most areas. Riepetown Formation: This unit is up to 1000 meters thick, and contains sandstones, siltstones, shales, limestones, and dolo- mites. It is coarser grained than the underlying and overlying forma- tions and is characterized by quartzose sandstones. Massive, thick sandstones occur in some areas (e.g., Murry Summit in the Egan Range), but the sandstones are normally thin and interbedded with other lithologies. The formation is most distinct in the type area in the central part of the basin and is less distinct to the west, north, and east. To the west it grades into predominantly fine-grained deposits of marl and calcareous siltstones. The Riepetown Formation is mostly of Wolfcampian age (determined from fusulinids and ammonites in the Egan Range, White Pine Range, and Maverick Springs Range). Bissell (1964) recorded middle and late Wolfcampian fusulinids from the Riepe- town in the type area, and Zabriskie (1970) recorded late Wolfcam- pian fusulinids from this unit in the Moorman Ranch area in the White Pine Range. Farther west in the Dry Mountain area, Stevens (1965) reported late Wolfcampian fusulinids in the Riepetown and early Leonardian fusulinids in the overlying calcareous siltstone lithologies (his Dry Mountain lithosome). In the Maverick Springs Range the late Wolfcampian fusulinid Schwagerina linearis Dunbar and Skinner, 1937 and the ammonite Medlicottia vetusta ? Ruzhent- zev, 1949 were collected from the upper part of the formation. The ammonite was submitted to and identified by W. Furnish and B. Glenister, who stated that it can be used as an indicator of late Sakmarian age (pers. comm., 1971). Pequop Formation: This formation is a thick sequence of car- bonates and shales conformably overlying the Riepetown Formation. It is predominantly carbonate and varies in thickness from 300 to 1300 meters (Zabriskie, 1970). This interval is widely recog- nized within the middle part of the Arcturus Group as a distinctive gt: BULLETIN 303 carbonate and shale unit overlying sandstones and siltstones of the Riepetown Formation and underlying shales, evaporites, and thin carbonates of the Loray Formation. Although the Pequop is widely recognized and mapped, there is no uniformity in naming it, and many workers refer to it simply as lower Arcturus Formation (using Arcturus Formation in a distinctly different sense than Arcturus Group). The Pequop thickens to the north at the expense of the Riepetown Formation and Loray Formation and in the central Pequop Mountains completely replaces the Riepetown Formation and most of the Loray Formation. The Pequop Formation is not present in the easternmost part of the basin. The Pequop Formation contains Leonardian age fusulinids in all stratigraphic sections; Robinson (1961) identified early, middle, and late Leonardian species in the richly fossiliferous type section. Wilson and Langenheim (1962) assigned a late Wolfcampian age to the lowest strata of the Pequop (lower Arcturus of their report) in the central Egan Range. A faunal collection in the middle of the Pequop in the Murry Summit section in the central Egan Range yielded the large gastropod Omphalotrochus [normally considered a Wolfcampian genus (Yochelson, 1961)], an evolutionarily primi- tive species of the fusulinid genus Parafusulina? (ident. by G. Wilde, 1971), and juvenile specimens of the ammonite Crimites elkoensis ? Miller, Furnish, and Clark, 1957 (ident. by Furnish and Glenister, pers. comm., 1971). The Parafusulina? sp. suggests a Leonardian age for this horizon, and a late Wolfcampian to early or middle Leonard- ian age is indicated for the Pequop Formation in the Murry Sum- mit section. The formation is clearly older here than in the type section. Loray Formation: This is the uppermost formation of the Arcturus Group, and is a sequence of evaporitic, terrigenous, and carbonate rocks with a mean thickness of about 300 meters. It has a sharp but conformable contact with the overlying Kaibab Forma- tion and a gradational contact with the underlying Pequop Forma- tion. The formational contact between the Pequop and Loray is arbitrarily placed at the base of the lowest redbed or evaporite horizon, or at the horizon where carbonates are no longer dominant in the stratigraphic section. Because of this gradational contact, many workers lump the two units together as one formation and PERMIAN BrRACHIOPODS AND Mo.ttiuscs: YANCEY 273 refer to the upper unit simply as upper Arcturus Formation. This confusion should not obscure its validity as a formational unit. The type section of the Loray Formation is in Elko County, north of the Hamilton Basin. On the north edge of the basin, in the central Pequop Mountains, it is thin and mostly replaced by the Pequop Formation (Yochelson and Fraser, 1973). In the central part of the Hamilton Basin it thickens and displays its typical characters, including evaporites and red beds. The Loray Formation has yielded few fossils useful for age determination. The fusulinid Pseudoreichelina cf. P. nevadaensis Douglass and Nestell, 1974 has been found in the lower part of the Loray Formation (loc. UCMP D-5539) in the Murry Summit sec- tion. The fusulinid is believed to be the same as P. nevadaensis from Spruce Mountain, Elko County, described by Douglass and Nestell (1974), but because it has been recovered only in acid insoluble residues, an exact comparison with the thin-sectioned material from Spruce Mountain has not been made. P. nevadaensis occurs in the upper Pequop Formation of Spruce Mountain, of late Leonardian age and indicates a probable late Leonardian age for the lower part of the Loray Formation in the Murry Summit section. This agrees well with the late Wolfcampian to early or middle Leonardian age for the underlying Pequop Formation in the same section and further indicates the older age of the Pequop Formation here compared to its type section. In the central Butte Mountains the Loray Formation contains members of the Neostreptognathodus sulcophcatus — N. prayi conodont assemblage zone, including the species N. prayi Behnken, 1975 and N. clinet Behnken, 1975. Behnken called this interval upper Arcturus Formation, and placed this zone in the middle to latest Leonardian. He stated that N. prayi and N. clinet imply an “upper Leonardian to lower Wordian” correlation in Nevada, and placed the Loray Formation in the Leonardian. The lower part or all of the overlying Kaibab Formation and the uppermost part of the under- lying Pequop Formation also contain conodonts of the NV. sulcoph- catus — N. prayi zone (Behnken, 1975, p. 293). Therefore the Leonardian-Guadalupian boundary would occur well above the Loray Formation, and the Loray Formation in the Hamilton Basin would have to be entirely Leonardian in age. 274 BuLuetIn 303 FOSSIL COLLECTIONS AND DESCRIPTION OF LOCALITIES All fossils used in this study were collected from stratigraphic sections where the biostratigraphic horizon of each sample could be determined accurately. Fossils were collected from stratigraphic sections throughout the Arcturus Group, although most collections were made from strata in the central part of the Hamilton Basin, and an emphasis was given to collection of samples from the upper part of the Arcturus Group which contains the more distinctive and lesser known biotas. Most of the Arcturus biotas are dominated by molluscs and brachiopods, so this study has concentrated on descrip- tion and determinations of the biostratigraphic ranges of species in those two groups. In addition to the fossils collected by the author, bivalves and gastropods from three sections in the post-Riepe Spring part of the Arcturus Group in western White Pine County, Nevada, were bor- rowed from collections of Calvin Stevens (California State Univer- sity, San Jose). Collections of fossils from the Arcturus Group, made by the U.S. Geological Survey, were examined to check for complete- ness of collections but have not been otherwise utilized here. Collec- tions of Arcturus Group fossils at Stanford University were examined for the same reason. Because they include so many borrowed specimens, the mol- luscs studied are from a wider range of environments than are the brachiopods (which are entirely from shallow-water environments). All groups of molluscs were studied except the ammonoids and chitons. The ammonoids were sent to Dr. Furnish and Dr. Glenister, University of Iowa. The chitons were sent to the late Allyn Smith, California Academy of Science. The localities of the fossil collections are given below. The locality descriptions for sample numbers with a letter prefix (D- 5516, etc.) are recorded in the files of the University of California Museum of Paleontology (UCMP) at Berkeley, California. Sample numbers with a number prefix (1J-2, etc.) are those of C. H. Stevens, Department of Geology, California State University, San Jose, Cali- fornia.

Discussion. — This small brachiopod is similar to L. carbonaria of the mid-continent region in all details except the smaller size and the modest inflation of the beak. The Arcturus specimens are about half the size of most upper Paleozoic Lingula specimens and appear to be juveniles. At loc. UCMP D-5591 about 15 specimens were collected on one bedding plane. These specimens are from 4-6 PERMIAN BRAcCHIOPODS AND Mo.uuscs: YANCEY 281 mm in length, and appear to be juveniles of a single year class. Partial specimens collected from nearby locality UCMP D-5592 are larger but still probably juveniles. The small size of Lingula at these locations may partly be caused by stunting from high salinity water. This species was described from upper Carboniferous strata, where it is widespread, and appears to be long ranging. Occurrence. — Loray Formation, loc. UCMP D-5591, D-5592, Butte Mountains, Nevada.

Description. — Small, ‘well-inflated rhipidomellid brachiopod; wider than long, with greatest width at midlength; width, 8 mm; length, 6 mm; with a slight fold and sulcus developed over the middle 1/3 of shell width; strongly developed ribbing consisting of thick hollow costellae in the middle part of the valve; inner margin of the valve finely corrugated with short, sharp grooves, correspond- ing to the ends of the hollow costellae; other characters not known. Discussion. — This species is identical in size and shape to the holotype of the species described and illustrated by King (1930). It has a characteristic greater width than length, and has coarse ribs over the median area of the valve. The high, narrow ventral cardinal area described by King (1930) cannot be seen on this material because of poor preservation but probably is present.

Description. — Well-inflated small to medium size Meekella with a large attenuated beak on the ventral valve and 15-20 major costae. Two sets of ribbing on the adult portion of the shell: a set of fine costellae covering the shell, increasing by intercalation and in some adult individuals having a costa of slightly larger size in the bottom of the interspace between major costae, and a set of coarse costae beginning at about 1/4 to 1/3 of the shell length from the beak and consisting of 15 to 20 costae covering the central and most of the lateral parts of the shell but not the lateral extremities along the hingeline; fine costellae tending to converge toward the crest of major costae; length of hingeline a little more than 1/2 of the total shell width. Ventral valve — exterior: ornament as above; shape an asymmetrical cone with midline of shell from beak to com- missure straight or slightly curved. Ventral valve — interior: with large dental plates separate and subparallel on attachments to valve and gradually divergent on attachments to interarea, projecting into hingeline as two strong sharp teeth. Dorsal valve — exterior: domed and strongly inflated; ornament as above. Dorsal valve — interior: cardinalia of strong high cardinal process supported by high and short, diverging crural plates which enclose adductor muscle scars, cardinal process of two gradually diverging bifid teeth, high and strongly recurved. PERMIAN Bracutopops AND Mottiuscs: YANCEY 283 Discussion. — This species is distinguished by the numerous large costae and the large attenuated beak of the ventral valve. The species is widespread and abundant in the American Southwest and has an age range from Wolfcampian to Guadalupian. It was gregarious in its life habits and is often found in peri-reefal situations (Stehli, 1954). Occurrence.— Upper part of Pequop Formation, loc. UCMP D-5540, Egan Range, Nevada. Family ORTHOTETIDAE Waagen, 1884 Subfamily DERBYIINAE Stehli, 1954 Genus DERBYIA Waagen, 1884 Derbyia sp. Pl. 1, figs. 4-5 Discussion.— Incomplete shells of the genus Derbyia are present at a few localities in the Arcturus Group. These specimens show the characters of the genus, a simple median septum in the ventral valve and large, bifid cardinal process with crural plates in the dorsal valve, but they are not complete enough to be spe- cifically identifiable. The material from loc. UCMP D-5629 was recovered from a thin layer composed mostly of Derbyia shells that are layered one on top of the other, and appear to result from a shell bank habit of growth, similar to modern oyster banks in warm temperate waters. All growth stages are present in the sample and the species grew to large size in maturity. Attachment of the shell appears to have occurred, but only at the tip of the beaks of juveniles, and in most cases the attachment was broken in later life. Occurrence. — Upper part of Riepetown Formation, loc. UCMP D-5639, lower part of the Loray Formation, loc. UCMP D-5629, in the Maverick Springs Range, Nevada; upper part of Pequop Forma- tion, loc.

PLA, Fig.G Chonetes sp., McKee, 1938, Carnegie Inst. Washington, Pub. 492, pp. 230-231, pl. 44, fig. 13. Description. — Adult shell subquadrate, with sides narrowing toward the front, and slightly auriculate at the hingeline; twice as wide as long with no sinus developed on front margin, and a small and depressed beak projecting a short distance over hingeline; about seven spine bases present on either side of beak, with spines pro- jecting at a high angle from the hingeline; well-developed fold and sulcus; interior of ventral valve with many pustules arranged in radial rows from the beak; other characters unknown. Discussion. — This species of Lissochonetes is represented by a single valve in the present collections, although it is more abundant in collections from this interval made by members of the U.S. Geo- logical Survey. The species is distinguished by width twice as great as length, moderately inflated folds bordering sulcus, and straight, converging sides with small ears slightly developed. It is similar to Lissochonetes geinitzianus (Waagen) in these features but is not discernably mucronate, and has larger pustules. It may represent a new species, but the types of Chonetes platynotus White should be examined first to determine the possibility of synonymy. Three chonetid species groups are present in strata of the Arcturus Group and correlative formations of the southwestern United States. Lissochonetes sp. of this report and Chonetes sp. of McKee (1938) are of one species group representing Lissochonetes sensu stricto, including species close to the type species. Chonetes kaitbabensis McKee (1938) and the closely related Chonetes ostio- latus Girty (1910) are in another species group, also in the genus Lissochonetes. A third group includes Chonetes subliratus of McKee (1938) and belongs in the genus Dyoros. Members of all three species groups may be found in Arcturus Group strata.

Discussion. — Incomplete shells of this species occur in a few localities and appear to be conspecific with Meek’s original material collected in Nevada, and with Phosphoria Formation material (Branson, 1930). Echinaurts subhorrida is more strongly sulcate and has much stronger costae than the type species, Echinaurts lateralis Muir-Wood and Cooper but otherwise is closely related. The type specimens of the species Avonia subhorrida newberryi McKee and Avonia dorsoconcava McKee were examined and they do not ap- pear to be specifically distinct from each other, nor from juveniles of Echinauris subhorrida. McKee (1938) separated the two species on the basis of size and shallower median sulcus. Both of these are growth related characters. He acknowledged that populations of these species were variable, and that the new species were established on extremes in the morphological variations. These extremes are not distinct enough to justify such a separation. Occurrence. — Upper part of Riepetown Formation, loc. UCMP D-5637, D-5639, D-5643, D-5644, Maverick Springs Range, Nevada.

Dorsal valve-exterior: same ornament as ven- tral valve, except covered by sparse small spines. Dorsal valve-in- terior: trilobate cardinal process supported by thickened hinge margins and a short tapering median ridge, succeeded anteriorly by a tall thin breviseptum; dense small endospines on anterior edge of visceral disc; ear chambers well demarked by ear baffles. Discussion. — This species is distinguished by its cancellate to costate sculpture and by the small but distinct ears. The ear cham- bers are distinct and set off by ear baffles in both valves. The species Squamaria spinosus (Winters) is identical to young speci- mens of Squamaria ivesi found in the Arcturus Group, and is synonymized. This species group is abundant in the Permian forma- tions of the western states. Further work is needed to see if other species can be defined among the extensive populations available for study. Squamaria ivest is abundant in the Arcturus Group and is the largest brachiopod commonly found. It is characteristic of shallow water deposition in areas of normal salinity and diverse fauna and is found in mixed carbonate and terrigenous sediments.

Superfamily PRODUCTACEA Waagen, 1883 Family LINOPRODUCTIDAE Stehli, 1954 Subfamily COSTELLARININAE Muir-Wood & Cooper, 1960 (as Costellariinae) Diagnosis. — Characterized by a simplified bilobed cardinal process, ventral valve with small interarea having delthyrium, and cicatrix terminating umbo. Ventral valve costellate and having elongate, suberect spines; brachial valve without spines. 288 BuLLeTIN 303 Discussion. — Costellarina is the only genus in the subfamily Costellarininae and is distinct enough to justify placement in a separate subfamily. However, its basic affinities are to the Produc- tacea, and it is here transferred from the Aulostegidae to the Lino- productidae. Its linoproductid affinities are best seen in the external features of costellation and spination but are also shown by the simplified cardinalia and breviseptum. The modified cardinal pro- cess appears to have evolved by simplification as a result of the small size of Costellarina, producing a convergence in form to the cardinal process of the productellids. The attached habit of most individuals is interpreted to be an adaptation from free-living an- cestors, a characteristic occasionally seen in Juresania (Muir-Wood & Cooper, 1960, p. 48, pl. 79). Costellarina probably had both at- tached and free-living niches. Free-living vs. attached life habits and cardinal processes are the most important characters used in classification at the suborder Most of these are valid, but attachment does occur among some productaceans, just as the free-living habit occurs in some stropha- losiaceans (see discussion of Lyttonia in Rudwick and Cowen, 1967) and the cardinal process is more variable in form within species and genera than has been recognized. Illustrations by Grant (1966) of a single species of Waagenoconcha show considerable variation of the cardinal process. Genus COSTELLARINA Cooper & Muir-Wood, 1967, emended herein Costellaria Muir-Wood & Cooper, 1960 (non Swainson, 1840 = Mollusca) Type species: Costellaria costellata Muir-Wood & Cooper, 1960. Description. — Emended. Ventral valve: Strongly inflated, weakly to strongly costellae, rugae variably developed, often present only near the beak. Having a single set of long body spines which are regularly distributed and curve anteriorly parallel to the curva- ture of the valve. Ears small, densely covered with spines slightly larger than body spines and extending posteriorly over the hingeline and laterally. Valves without fold or sulcus, maintaining a smoothly expanding growth curve throughout life, without flares. Umbo terminated by a cicatrix; short interarea with delthyrium closed by cardinal process of dorsal valve. Body spines having tubular exten- PERMIAN BrRACHIOPODS AND Mo.iuscs: YANCEY 289 sions (atrial tunnels) on the valve interior that extend anteriorly from the spine base a short distance and terminate before reaching a new spine. Dorsal valve: Flattened on younger portions, then assuming growth shape of ventral valve, containing few or many short endo- spines on anterior part of valve but without external spines. Cardinal process small with strongly diverging lobes which bear a median slit and recurve over the hingeline, and supported by widely diverging lateral ridges that merge with thickened hinge line ridges. Brevi- septum small, located near center of visceral disc. Adductor muscle field poorly defined. Spine bases: The body spines in Costellarina are often perched on small nodes which are usually elongate in the direction of growth. The hollow interior of the spine continues into the visceral cavity. Where it emerges on the interior of the shell it bends sharply an- teriorly and is continuous with the atrial ridge (Text-fig. 5). The atrial ridge is a hollow extension of the spine in the form of a tunnel on the inner surface of the valve and extends anteriorly, parallel to the line of growth of the spine. The atrial ridge is about the same thickness as the spine, and appreciably thickens the shell wall. It extends a varying distance forward from the base of the spine and tapers abruptly on the anterior end. Within a uniformly short distance after the termination of the atrial ridge a new spine is formed. There is obviously a functional relationship between the atrial ridge and the production of new spines. While the old spine is being maintained and is growing, the atrial ridge is being lengthened. When this ceases the atrial tunnel is sealed off and a new spine is grown anterior to the old one. The atrial tunnels contain lobes of mantle tissue which are separated from the expanding visceral tissue by the roof of the tunnel. The spines on the lateral ears of the pedicle valve are not closed off at maturity as are the body spines. It is probable that they continue growing throughout the life of the individual. Atrial ridges have been noticed by Grant (1966) and Waterhouse (1971), but the reconstruction of Grant (1966) is made on the assumption that they remain open to the interior long after the spine is first formed and as the shell is thickened. This is doubtful, even for Waagenoconcha, and the atrial tunnel and ridge indicate a relatively short life for the 290 BULLETIN 303 growth of the spines. Discussion. — The emended description of this genus corrects the description of the spines which are typically productacean and consist of only one type although they are slightly larger on ears than on the body, and are not rhizoid, nor are there any prostrate spines. The body spines do have anteriorly directed tubular exten- sions (atrial ridges) on the interior of the valve. The reference to lack of elytridium is removed, since that feature is normally present only in the Strophalosiacea. Costellarina is a small, simplified genus that lacks close rela- tions. It is closest to Cancrinella but differs from that genus in its modified cardinalia. Although Muir-Wood and Cooper (1960) classi- fied it in the Aulostegidae, the cardinal process (which they use as Text-figure 5. Drawing of the characters of spines and atrial ridges in Costellarina, based mostly on a young specimen of C. kaasai paratype UCMP 14303.

Magnification approx. X 20. PERMIAN Bracuiopops AND Mo.tuuscs: YANCEY 291 a prime character in classification) is not similar to typical aulo- stegid cardinal processes. It is simplified, lacks a shaft, and is simi- lar to the productellid type (a fact also noted by Muir-Wood and Cooper) which is normally bilobed and supported by short di- verging lateral ridges. In external features the genus is most similar to Cancrinella and the Linoproductidae, so much so that it was described as a homeomorph of Cancrinella. Some features of the cardinalia also suggest relationship to Cancrinella. It is probable that Costellarina evolved from Cancrinella by modifications resulting from prolonged period of attachment. The presence of a relatively large cicatrix of attachment was the major justification for assign- ment to the Strophalosiacea (Aulostegidae). Species presently placed in Costellarina are C. costellata (the type species), and C. kaasai, n. sp., C. plasi, n. sp. and C. carlstroem, n. sp. In addition, the species Terrakea arctica, described by Water- house (1971), probably belongs in this genus. The holotype and paratypes of 7. arctica are clearly related to Costellarina, but the hypotypes illustrated in the same article are not and belong in dif- ferent genera. Since Waterhouse’s reconstruction of the cardinalia of T. arctica was based on hypotype specimens, this feature of the species is still unknown. The other features of size, shape, costella- tion, spination, and atrial ridges of the primary types all indicate relationship to Costellarina. Costellarina is usually found in a matrix of terrigenous limestone or calcareous clastic rocks, indicating an originally muddy substrate with varying dominant grain size. The greatest abundances of in- dividuals are found in rocks of the finest grain size. Costellarina is abundant in depositional environments where sedimentation rates were probably high, and in stratigraphic sequences containing many shallow-water indicators such as redbeds, evaporite deposits, and stromatolites. It occurs commonly in restricted, mollusc-dominated faunas. The known distribution of Costellarina broadly parallels the distribution of abundant terrigenous limestones in the lower Permian, and conclusions on the paleogeographic range of the genus must take into account the presence or absence of this rock type. Life habits. — Costellarina is a unique productid in that it was capable of living attached or free. The cicatrix of attachment shows that individuals were attached to a substrate as young. The size of 292 BULLETIN 303 the cicatrix varies considerably and for most it is too small for an animal that was attached throughout life. They probably detached upon reaching maturity. The attachment surface is almost always smooth and flat, and only rarely is it small or found to have attached to a strongly curved surface. The brachiopod must have been at- tached to another organism because the sea floor substrate was soft sediment, but often no suitable form is preserved. The most likely substrate for attachment was blades of seaweed, as suggested by Stevens (1966). There is no direct evidence of seaweed in the strata now, but Elias (1937) demonstrated the presence of abundant fleshy seaweed in the lower Permian of Kansas. Attachment spines are rare. It appears that attachment by shell cementation was weak enough to allow the shell to fall to the bottom when it grew large enough. Costellarina has several shell features which suggest a free-living adult habit. The adult shell is well inflated and has halteroid lateral spines and abundant long curved body spines. These shell characters, and the common occurrence of individuals in clusters, suggest a free-living habit of the adult form similar to the life habits of Waagenoconcha, Marginifera, and Echinauris (Grant, 1966, 1968), which lived nearly buried in sediment with the brachial valve and anterior margin exposed, and were supported in the sediment by the spines. Articulated individuals of Costellarina containing geo- petal accumulations of clay and spar-filled areas under the beak, similar to geopetal orientations of Waagenoconcha and Marginifera, have been found in collections of the genus from the Colina Forma- tion in Arizona. Variation. — Collections of Costellarina from Arizona, Utah, and Nevada containing hundreds of individuals, show that variation within a cluster of individuals (here considered to be a population, and henceforth called a population) is limited. The most variable feature within a population is the shape of the shell. The major varia- tion in the species is in differences between populations, so that the species contains a large number of distinct populations which are part of an intergradational series. A single population does not in- clude morphologic forms representative of the entire species, and only by examining several large populations can the full range of variation be indicated. PERMIAN BrRAcHIOPODS AND Mo.iuscs: YANCEY 293 Within a population the shell shape varies from quadrate to elongate but this variation is greater in some populations than in others. The amount of shell inflation, and the degree of rugation near the beak is less variable. The size, density, and curvature of the body spines is nearly constant within a population. The strength of rib- bing is a nearly constant character within a population, but varies between populations, and is variable enough to cause some diffi- culty in species discrimination when only limited samples are avail- able.

Description. — Ventral valve: Small, well-inflated Costellarina with a single set of spines sparsely and regularly scattered over the ventral valve, about 2 mm apart on the anterior margin, leaving the shell at an angle of 30-40 degrees and subsequently curving toward the shell surface to become parallel to it at several mm from the shell surface; ribbing consisting of a few or many weak costellae, rarely none, and weakly developed rugation on the beak area; large individuals becoming slightly elongate; other features as for genus. Dorsal valve: Cardinalia as for genus; small endospines usually present on the anterior margin of the visceral disc, variable in num- ber; other features as for genus. Discussion. — This species is distinguished by the loose, open arrangement of the spines and the weak ribbing of the ventral valve. It is variable in its ribbing and rugation, because in some populations the ribbing is nearly obsolete while in others there are many well- developed small costellae. A weakly ribbed condition is normal for the species. The spines are openly curved and extend some distance away from the surface of the valve. This common species has prob- ably been confused with other small productids, or considered to be juveniles of known species by other workers. It is similar to illustra- tions of Avonia dorsoconcava as described and illustrated by McKee (1938), but examination of the types of A. dorsoconcava shows that it is a synonym of Echinauris subhorrida. Costellarina kaasat can be distinguished from E. subhorrida by the presence of a cicatrix, 294. BuLtetTIn 303 absence of a pointed beak, subcircular shape, and absence of a sul- cus. C. kaasai is most similar to C. carlstroemi but differs from that species in having more abundant and more slender spines. C. kaasai is similar to Costellarina arctica (Waterhouse), but C. arctica can be distinguished by its larger ears and greater width/length ratio. Costellarina kaasai occurs in a wide range of nearshore shallow- water environments. It is most often found in marginal marine situations with a biota of limited diversity, indicating semi-restricted conditions. It is especially characteristic in mollusc-dominated biotas but is also found in more diversified normal marine biotas having abundant brachiopods, bryozoans, and echinoderms. It is found in a variety of lithologies but most often in a sandy mud. This is the most abundant brachiopod species in the Arcturus Group of Nevada- Utah and is widespread in the lower Permian. Occurrence. — Throughout the Riepetown Formation, Pequop Formation, and Loray Formation of the Arcturus Group in Nevada and Utah, and in correlative strata in west central Utah. Ranging in age from late Wolfcampian (in Riepetown Formation) to late Leonardian (in Loray Formation).

Discusston.— This species is distinguished from other species in the genus by the tight curvature of the spines over the shell, and by spines that are slightly smaller in diameter than in the other species. The species is slightly smaller than C. kaasai and much less strongly costellate than C. costellata. When the curvature of the spines cannot be determined, the stronger costellation is a useful means of separating C. plasi from C. kaasai. Costellarina plasi occurs in more open marine environments than C. kaasat, and is found in biotas of high diversity. It probably lived in less turbid conditions and in slightly higher energy condi- tions than C. kaasat. Occurrence. — Pequop Formation, loc. UCMP D-5535; lower part of Loray Formation, loc.

Costellarina carlstroemi, n. sp. Pl. 3, figs. 6-10 Description. — Ventral valve: Small to medium-sized, well in- flated; with a single set of robust spines scattered over the ventral valve, spaced from 2-4 mm apart along margin, leaving the shell at an angle of about 30-40 degrees and curving towards shell; ribbing of numerous small, broad costellae; shape subquadrate to sub- rounded; rugation lacking or weak; other features as for genus. Dorsal valve: Features as for genus. Discussion — This species is distinguished from other species in the genus by the relatively large, robust spines which are less numerous, both on the ears and body of the shell than in any other 296 BuLueTIn 303 species known in the genus. It is most similar to C. kaasai which has a similar shape and a similar curvature of spines. C. carlstroemi can be separated from both C. kaasai and C. plasi by the less numerous, but larger and more robust spines. This species is described here for comparison with the Arcturus species, and is of interest because it is the most southerly known species in the genus, and probably lived in subtropical climates.

Pl. 4, figs. 1-4 Description. — Small shell with strong fold and sulcus which is strongly plicate, with plications limited to anterior half of shell; subtriangular in outline, well inflated; ventral valve projecting be- yond dorsal valve, with deltidial plates leaving free oval foramen; internal characters not seen; fold bearing two strong plications, and sides of fold and sulcus converging dorsally; lateral slopes bearing one or two smaller plications, these extending about a quarter of distance to beak. Discussion. — Cooper and Grant (1976) revised the Texas Permian rhynchonellids, described many new genera, and changed the basis for classification of this group. Details of the interior of this species are unknown, and it cannot be identified to genus with certainty. Furthermore, this is a bidentate form, which is possibly a variant of a tridentate species, as discussed by Cooper and Grant (1976, p. 1951) for Wellerella bidentata Girty. More individuals are needed for identification of this species. Occurrence. — Pequop Formation, loc. UCMP D-5617, Medi- cine Range, Nevada.

Description. — Small, well inflated, with distinct but weakly developed plications on a moderately high fold and sulcus, and an oval to subrounded outline; plications extending about a third of length of shell; three plications present on fold, and a single weak plication on lateral slopes; margins of fold and sulcus converging rapidly dorsally; internal features not seen. Discussion. — This species is readily distinguished on the basis of its oval to subcircular outline, and weakly developed plications. The number of plications on the fold and lateral slopes is variable, but a triplicate condition is typical. Until the internal characters are known from etched specimens, the generic assignment is uncertain. Occurrence. — Riepetown Formation, loc. UCMP B-6217; Pe- quop Formation, loc.

Description. — Small, well-inflated form with ventral beak over- hanging the dorsal valve a short distance; shells subquadrate or subcircular in outline, with slightly greater length than width; fold and sulcus not developed, and shell margin slightly squared off on anterior margin; shell ornamented with characteristic overlapping fimbriate lamellae of small size; greatest width in central part of shell; beaks rounded, not attenuated; interior unknown. Discussion. — This species is close to the types of C. ciriacksi described by Cooper and Grant (1976) from upper Permian Franson member of the Park City Formation in Montana. It is similar in in- 298 BuLLETIN 303 flation of valves, and the slight folding of the plane of commissure, but differs in being slightly longer than wide instead of wider than long, and being slightly larger than the types of C. ciriackst. These minor differences are probably due to population variation. The Arcturus specimens are from an older horizon (Leonardian) than the types (probable Guadalupian). The possibility of evolutionary change within the species needs to be examined when further ma- terial is available, but the range of variation within a species of the genus may be as great as in the genus Composita with which it is closely related. The genus occurs in conditions of normal marine environment with a diverse biota. Occurrence. — Pequop Formation, loc. UCMP D-5535, D-5546, Egan Range, and loc. UCMP D-5626, Medicine Range, Nevada.

Description. — Shell small to medium size (up to 12 mm wide), of ovoid shape, as wide as long; well inflated, with widest part close to mid part of shell; beak of ventral valve prominent and over- hanging; fold and sulcus well developed on later-formed half of valve and slightly more than half as wide as the valve; on most adult shells the articulation line of fold and sulcus having a characteristic tonguelike shape on the plane of commissure — wide and low, with short steep sides, and gently curving along top of fold — changing to a high sinusoidal curve having height about equal to width at largest growth stage of shell; on large shells fold and sulcus bordered by a lesser sulcus on either side, which are appressed to the shell, fold and sulcus tongue thus projecting anteriorly; sulcus usually marked with a shallow well-defined groove along the median line; interior characters as for genus. PERMIAN Bracuiopops AND Mo.tiuscs: YANCEY 299 Discussion.— The wide and nearly flat-topped fold and the well-developed shallow groove on the sulcus of most large individuals are the characteristic features for these populations of the species. However, the groove on the sulcus is not always present on all indivi- duals. The fold and sulcus changes shape during ontogeny, develop- ing a tonguelike shape at maturity, and changing to a high sinusoidal curve at largest growth size. Individuals with the high sinusoidal fold and sulcus are few, since the majority of individuals in each sample are juveniles and small adults. The species Composita parva and Composita arizonica are placed in synonymy with Composita mexicana because of their overall similarity of form, similarity in development of fold and sulcus, and similar ages of occurrence. C’. mexicana is variable, as are all Composita species, but it is closely related to Composita subtilita (Hall), differing mostly in its smaller size and more projecting fold and sulcus tongue. The Arcturus populations are closest to the morphological form described as Composita arizonica by McKee (1938), in the shape, size, and amount of anterior projection. The description by McKee (1938) does not indicate a median sinus or groove on the sulcus, but this is probably an oversight, due to poor preservation of material. As suggested by McKee (1938) and Grin- nell and Andrews (1964), C. arizonica may be transitional between Composita subtita and Composita mexicana, and a part of an evo- lutionary continuum between the two species. However, because of the variability of species in the genus, this form is not consistently separable from C. mexicana, and is best regarded as C. mexicana proper. Occurrence. — Pequop Formation, loc.

Discussion. — This species is distinguished by its large size and flattened form. The available material of this form is incomplete but can be recognized by the flat form of even the juvenile shells.

Description. — Shell elongate, with greatest width about 3/5 distance from beak and equal to about 2/3 of the length; moderately to highly inflated; beak of ventral valve prominent and overhang- ing, with open foramen; shape tending to a pentagonal outline, with slightly projecting fold and sulcus that is squared off in front; fold and sulcus slightly developed, and wide; greatest size 9 mm by 11 mm; internal characters not known. Discussion. — This species is similar to Composita elongata, but is less inflated and rotund, and not so narrow as the types of the species, which are nearly parallel sided. They are close in all charac- ters except size to C. emarginata affinis of King (1930) and are similar to one specimen of C. subtilita (Branson, 1930, plate 9, figure 11). These authors did not distinguish this form from other species of the genus. It lacks a name but seems characteristic of the middle Permian. The Arcturus Group specimens are small and are probably juveniles. The growth series and range of characters in populations of this species are not known. This species appears to be descended from Composita elongata. Occurrence. — Pequop Formation, loc. UCMP D-5535, Egan Range, Nevada.

Type species: Wilberrya fragilis, n. sp. Description. — Small, thin-shelled, and rounded in shape; well inflated; ventral valve larger than dorsal valve, and more inflated; hingeline short and poorly defined, with two tooth processes on each valve; interarea present but poorly defined on ventral valve; shell has a weakly developed fold and sulcus; ornament consists of small, weakly developed costellae. Ventral valve: Strongly inflated valve with overhanging but not prominent beak; interarea contain- ing an open delthyrium bounded by low ridges which project as tooth processes. Dorsal valve: Moderately inflated valve with slightly projecting beak; with well-formed tooth sockets having inner socket ridges elevated and expanded to form large toothlike projections; con- taining long thin crura connected to the base of the tooth sockets; crura elevated above the floor of the valve and not connected to it, and projecting anteriorly, curved parallel to the floor of the valve. Discussion. — This genus is characterized by its form, weakly costellate ornament, short indistinct hingeline, and simple cardinalia with long thin crura; features which distinguish it from all other common smooth late Paleozoic ambocoeliids It is closely related to Crurithyris. It also superficially looks like Phricodothyris or Mar- tinia (of the Reticulariacea) but can be distinguished from them by the absence of concentric lamellae and by the internal features (lack of crural plates or dental plates or median septum). It differs from Crurithyris and other ambocoeliids by the short, indistinct hingeline, by the much more equivalved and more rounded form, and by the presence of costellae (the only other ambocoeliid known to possess costellae is the Devonian genus Ladjia). The cardinalia of Crurithyris, described and illustrated by Brunton and Champion (1974) for British Isles species, shows definite relationship to Wilberrya. Internal characters of the two genera differ primarily in the development of stronger tooth pro- cesses and the absence of even a rudimentary cardinal process in Wilberrya (Text-fig. 6). In British species of Crurithyris these characters show progressive changes through time, with the youngest 302 BULLETIN 303 A Text-figure 6.

Drawn from specimens shown in fig. 8, Plate 5, ard fig. 13-14, Plate 5. species most similar to Wilberrya. Furthermore, there is a progres- sive reduction of the crural bases in Crurithyris approaching the condition found in Wilberrya. These morphologic progressions indi- cate that Wilberrya is a direct descendant of Crurithyris. Wilberrya is uncommon in the biotas in which it is found. It oc- curs in predominantly molluscan faunas in the Arcturus Group, and appears to have been tolerant of nearshore environmental conditions (periodic high turbidity and high energy). Brabb and Grant (1971) illustrated a larger unnamed species of this genus (listed as Martinia sp. undet.) from the Tahkandit Formation of Alaska which contains an arctic type fauna. Gobbett (1963) and Bamber and Waterhouse (1971) illustrated specimens of “Martinia sp.” which may well be- long in this genus, but the internal features of these forms are not known. Etymology. — Named for W. B. N. Berry, of the Dept. of Paleontology, University of California, Berkeley. Wilberrya fragilis, n. sp. Pl. 5, figs. 8-19 Description. — Ventral valve: Small, thin-shelled, wider than long, with greatest width just anterior to the hingeline; hingeline short; valve well-inflated, with slight fold and sulcus developed and a broad low fold on each lateral slope at maturity; beak overhang- ing, not prominent, and strongly incurved; interarea low, containing an open delthyrium bounded by low ridges which project as tooth PERMIAN BRACHIOPODS AND Mo.iuscs: YANCEY 303 processes, diverging from each other at an angle of about 40 degrees and high standing; tooth processes as curved plates; dental plates and septum lacking; ornament consisting of subdued costellae. Dorsal valve: Small, well-inflated, thin-shelled, with beak slightly projecting; fine costellae covering the valve; juvenile form elongate, becoming wider than long at maturity, and also less inflated; con- taining well-formed tooth sockets in the cardinalia enclosing a small triangular notothyrium, with the inner socket ridges elevated and expanded on their extremities to form large toothlike projections, these diverging from each other at an angle of about 45 degrees and high standing; containing long thin crura connected to the bases of the tooth sockets, elevated above the floor of the valve and not con- nected to it; crural bases projecting anteriorly and curving parallel to the floor of the valve (Text-fig. 6). Discussion. — The presence of costellae and absence of concen- tric plications, and the small size of this species distinguish it from other ambocoeliid or reticulariacean species. The specimens at hand show variation in the strength of the fold and sulcus and accessory folds and in the strength of costellae on the valves. All folds are broad and low and become stronger with maturity, so considerable variation in the strength of folds can be expected. Nonetheless, among the specimens examined there is a correlation of stronger ribbing associated with weaker folding of the plane of commissure. This appears to be intraspecific and indicates a moderate range of variation within the species. The globose, highly inflated shell, open delthyrium and fragile shell indicate a probable epifaunal habit. The shells were probably attached to arborescent taxa living above the bottom sediments, either sea weed, sponges, bryozoans or crinoids. Occurrence. —Upper Pequop Formation, loc.

Phylum MOLLUSCA Class SCAPHOPODA Bronn, 1862 Order DENTALIOIDA Palmer, 1974 Family DENTALIIDAE Gray, 1847 Discussion. — This family includes the two common genera of Paleozoic scaphopods, Prodentalium and Plagtoglypta, in which nearly all Paleozoic scaphopods are placed. Prodentaliwm includes the commonest species of scaphopods in Carboniferous and Permian strata, and includes species with large heavy shells that have longitu- dinal ribbing [such as P. raymondi Young and P. canna (White) ]. Most of the species that were previously placed in Plagioglypta should be transferred to Prodentalium (Yancey, 1973 a,b), but there are some small species with strong concentric ornament that are retained in Plagioglypta [such as P. meekiana (Geinitz) ]. Another generic group is represented by long, slender thin-shelled scaphopods with smooth surfaces which are fairly common in Carboniferous strata. These compare closely with modern Dentaliwm (Laeviden- talwm) and are represented in the Paleozoic by D. (L.) venustum Meek & Worthen and related forms. Scaphopods with strong and widely spaced ribs are placed in the newly described Dentalhum (Paleodentaliwm) (Gentile, 1974), which occurs uncommonly in upper Carboniferous strata. Scaphopods are a common element in molluscan faunas of both shallow- and deep-water environments of the upper Paleozoic. Prodentalium is common in shallow-water molluscan communities, where it attains great size and has an adult shell of considerable mass. It is one of the largest molluscs living in those communities. Genus PRODENTALIUM Young, 1942 Type species: Prodentalium raymondi Young, 1942. 306 BULLETIN 303 Description. — Long, gently curved scaphopods with a thick shell, having longitudinal ribbing consisting of many small ribs, these reduced in size anteriorly; ribs slightly zigzag or offset in alignment; growth lines oblique; some species very large; shell wall thick. Discussion. — The main characters for distinguishing Proden- talium are its small longitudinal ribs, gentle curvature, and its thick shell wall. Most of the common species of Carboniferous and Permian scaphopods belong in the genus Prodentaliwm, and nearly all of the larger species of these periods belong to this genus. Some of these are species which lived in large populations in shallow, nearshore environments, and often grew to large size. These, and other species of the genus, were originally described as Dentalium, and the longitudinally striate character was noted. When the genus Plagioglypta was defined, the striae were ignored and all forms which appeared to have an annulated character were assigned to Plagio- glypta. This was a mistake, based on observations of worn indivi- duals. It was not corrected until the new generic name Prodentalium was established on Paleozoic material and better observations and descriptions were made on known material. Species presently assigned to Prodentalium are: Prodentalium raymondi Young — the type species Dentalium semicostatum Girty Dentalium canna White — the commonest and most widely cited scaphopod species of the Permian Dentalium mexicanum Girty Dentalium indianum Girty Dentalium sublaeve Hall Plagioglypta monolineata Branson This is not a complete listing of species in the genus, but it includes all of the upper Carboniferous and Permian species known in North America. The species Prodentaliwm belcheri Nassichuk and Hodgkin- son, 1976, is not a species of Prodentalium, and probably not a scaphopod. Prodentaliwm has a thick shell wall, with shell layers angled to the outer surface, P. belchert has a thin shell wall with shell layers nearly parallel to the outer surface. Prodentalium in- creases regularly in diameter and has a regular rate of curvature, P. belchert is irregularly curved and increases in diameter irregularly. The aperture of P. belcheri is irregularly constricted, and it is prob- able that it is not a molluscan species, but a calcareous worm tube. PERMIAN Bracutorpops AND Mo.uiuscs: YANCEY 307 Some of these nominal species are synonyms of other species due to their original descriptions being based on fragmentary ma- terial. As noted by Miller (1949) the type species of Prodentalium is variable in both size and irregularities of ornament. This vari- ability is similar to that occurring in modern species of scaphopods. There is a characteristic progression in ornamentation during onto- geny in Prodentalium, and this feature is probably the best means of distinguishing species. Characters used to discriminate species are size of ribs, density of ribbing, ontogenetic change in ribbing, adult size of shell, and curvature of shell. The density of ribbing is a major character of differentiation between species. A comparison of the density of ribbing on the type specimens of the species listed above follows: Prodentalium sublaeve (plastotypes) —3 ribs/mm on 3.5 mm diameter shell 2 4 (same lot) — 2-3 ribs/mm on 12 mm 2 , P. raymondi paratype) —4=+ ribs/mm on 10 mm PY ?

Except for Prodentalium raymondi, the ribbing density measurements for all the types were made by me on type specimens at the U.S. National Museum (including plastotypes of Dentaliwm sublaeve). Four species, based on ribbing densities, can be recognized within this group. Suggested diagnoses and synonymies of species are given as follows: 1) Prodentalium sublaeve (Hall), 1858 — having about 3 ribs/mm as a juvenile and about 2-3 ribs/mm as an adult (12 mm diameter); the species is distinguished by low density of ribbing; Carboniferous in age. Synonyms. — Dentalium acutisulcatum Gurley, 1883 — placed in synonymy by M. L. Cooper in an unpublished MS thesis (Kent State, 1972). This lower Carboniferous species has a ribbing density similar to P. sublaeve. 308 BULLETIN 303 2) Prodentalium raymondi Young, 1942 — large as adults, attain- ing a diameter of 30 mm and length of 30 cm on some individuals; having about four ribs/mm on middle diameter (10 mm diameter) and about three ribs/mm on full grown adult shells (25 mm diameter); species distinguished by its large size and high density of ribbing. P. raymond: is restricted to the upper Carboniferous (Pennsylvanian) (pers. comm., E. L. Yochelson, 1971) and is prob- ably the ancestor of the Permian species P. canna. 3) Prodentalium canna (White), 1874 — large scaphopods; having a ribbing density of 5-6 ribs/mm on a small diameter (5 mm diameter) and 3-4 ribs/mm on a large diameter (10 mm); species distinguished from P. raymond: primarily by its smaller size and more regular shape but has a similar ribbing pattern. P. canna is probably descendent from P. raymondi and is restricted to the Permian. Synonyms. — Plagioglypta monolineata Branson, 1930 — a sub- jective junior synonym (Yancey, 1973b); Dentalium mexicanum Girty, 1909 — probably a junior synonym. 4) Prodentalium semicostatum (Girty), 1915 — has a ribbing den- sity of 4-5 ribs/mm on small diameter (diameters of 2.5 to 5 mm), ribs small and low in profile; distinguished by an intermediate rib- bing density between P. sublaeve and P. raymondt — P. canna. Without more complete material there is no way to determine con- clusively if this represents a distinct species, or juveniles of P. ray- mondt, but the different ribbing density suggests that it is a separate species.

America, vol. 63, No. 2, ie canna (White), Yancey, 1973, Jour. Paleont., vol. 47, No. 6, p. 1126. Description. — Large scaphopods probably attaining total length of 20-25 cm for complete mature forms; shell diameter about 2 cm in mature forms, with shell wall thickness in midreaches rang- ing up to 4-6 mm; shell greatly curved on young portion and nearly straight on adult portion; ornament consisting of longitudinal ribs, slightly zigzag, strongly raised on juvenile portion of shell, becoming lower, weaker, and wider during growth, new ribs added by inter- calation; rib density about 5/mm on juvenile shell (up to 5 mm diameter) changing to 3-4/mm on adult shell (10 mm in diameter); ribbing obsolete or lost on apertural areas of large shells. Discusston.— This species was well described by Yancey (1973b). It is closely related to P. raymondi and is clearly a descen- dent of that species. It differs from P. raymondi in its smaller adult size, but the ribbing and general form are the same. At the present time the adult size is the only meaningful character by which to separate the two species. Partly this is due to a lack of knowledge of the juvenile portions of P. raymondt. Prodentalium canna lived in a range of environments from fully normal marine to marginal marine, variable salinity conditions. It has not been found in definitely deeper water environments, and ap- pears to have inhabited shallow waters nearly exclusively. It is present in diverse normal marine biotas but is most common in restricted marginal marine biotas, where it is often present in large numbers. Populations which inhabited marginal marine conditions produced the largest individuals. Occurrence. — Very common in the Riepetown, Pequop and Loray formations in the Egan Range, Butte Mountains, Maverick Springs Range and Medicine Range, Nevada; common in Arcturus Formation, Confusion Range, Utah. Order SIPHONODENTALIOIDA Palmer, 1974 Family SIPHONODENTALIIDAE Simroth, 1894 Genus CALSTEVENUS Yancey, 1973 Type species: Calstevenus arcturus Yancey, 1973. Description. — Small, short scaphopods, with rapid width ex- 310 BULLETIN 303 pansion; curvature of shell relatively strong; growth lines oblique to axis of shell, at an angle of about 75 degrees to axis; apex simple, without notch or lobes, with earlier apical areas not present, and presumably resorbed; ornamentation consisting only of weak growth lines; shell wall thin. Discussion. — This genus includes only one described species, which is the only definite pre-Cretaceous species of the siphono- dentalids known. Its simple form and small size suggest that it is part of the original evolutionary stock of the siphonodentalids. Calstevenus arcturus is similar in size and shape to Plagioglypta meekiana (Geinitz) although differing greatly in surface features. These two species clearly belong in different genera, but the simi- larities between them suggest that P. meekiana might have siphono- dentalid affinities. Further study on P. meekiana is needed to verify this. Calstevenus arcturus Yancey, 1973 Pl. 6, figs. 12-14 Calstevenus arcturus Yancey, 1973, Jour. Paleont. vol. 47, No. 6, p. 1063, text- figs. 1a-1f. Description. — Shell small, 1.0-1.5 cm long for adults, 1.0 mm in diameter at apex and 2.0 mm in diameter at aperture; shell thick- ness 0.2 mm for adults; curved, with greatest curvature in apical regions; growth lines oblique, at an angle of about 75 degrees to axis; ornamentation consisting only of numerous faint growth lines; rapid increase in diameter with growth, increase continuous through- out life of individual; apical areas truncated and apparently re- sorbed. Discussion.— This species is known only from the calcareous siltstones of the Dry Mountain “lithosome” of the Riepetown Formation and appears to have lived only in muddy substrates in low energy environments in probably deeper waters. It is common in this environment, although unknown elsewhere in the Arcturus Group. It normally occurs with a molluscan fauna including am- monites, taxodont bivalves, and thin-shelled bivalves. Occurrence. — Dry Mountain “lithosome” of Riepetown Forma- tion, loc. 1J-2 (type locality), 1J-6 at Buck Mountain, 1K-8 at Dry Mountain, 1X-1, 1X-3, 1X-8 at Limestone Peak, White Pine Range, Nevada; also from about the middle of Dry Mountain “lithosome” at Maverick Springs Range, Nevada.

Description. — Shell large, greatly inflated, with rounded and smooth central body portion; prominent curved beaks nearly touch- ing at hingeline; ornament of weak growth lines and weak, smoothed ribs over most of shell; strongly differentiated anterior portion of shell, with shell wall there about three times as thick as on remainder of shell, and with strong radial ribs; small, nearly obsolete posterior rostral tube which may have thickened shell wall; hingeline long and straight; shell wall containing radial rods, rods most distinct in beak areas, forming subdued ribbing; large internal shelf on inside of anterior portion of each valve, with secondary shelves in large individuals. Discussion. — Arceodomus includes several species which are distinct from other conocardiids in the lack of external ribbing on the body of the shell. This part of the shell has internal ribbing that is not exposed unless the shell has been eroded. In addition to the type species Conocardium glabratum Easton, 1962, the species C. japonicum Nishida, 1968, C. ouralicum Verneuil, 1845 (discussion in Wilson, 1970), and C. langenheimi Wilson, 1970 can be referred to the genus Arceodomus. The first three species are of Carboni- ferous age and are similar in general form, being more elongate and more strongly ribbed than the Permian species A. Jangenheimt. These differences suggest an evolutionary change from the Carboniferous to Permian species involving reduction in size of anterior snout, and shortened length of shell. Short, highly inflated species appear to have evolved in the Permian, and to be confined to that period.

Fh2 BuLtetTIN 303 Description. — Shell large, greatly inflated and rounded, up to 7 cm in length, with height about 2/3 of length and width about 1/2 of length; ventral margin subparallel to hingeline; posterior shell surface smooth with occasional growth lines and faint smoothed ribs on beak areas; valves tightly articulated and denticulate on inner margin, except at rostrum and anterior portion; strongly differen- tiated anterior snout projection with shell wall 2-3 mm in thickness, about three times as thick as the other shell wall, and strongly ribbed, ribs sharp and high, separated by flat spaces about two- three times rib width; anterior gape; complexly shaped internal shelf on middle of inside of anterior projection, which projects nor- mal to the shell wall in juveniles but is angled downward in adults, a secondary shelf below the first shelf in larger individuals; shell wall of major part of valve containing radial rods, rods creating a slight ribbing on the outside of valve, and fairly strong ribbing on the inside of juvenile and young valves; small and short rostrum present on posterior end of hingeline, rostrum having a partly thick- ened shell wall. Discussion. — This species can be easily recognized among the conocardiids by the large, smooth, rounded posterior portion of the shell, the relatively high beak areas, and the equilaterally triangular shape of the anterior snout projection. In many external features (except the anterior snout projection) it resembles a well-inflated edmondacean rather than a conocardiid, and in shape, beaks and degree of inflation it closely resembles Edmondia subtruncata from the Gaptank Formation (Bird, 1968). No relationship is suggested by making this comparison, but it is possible that many individuals of this species or related species have been misidentified as Ed- mondia, if the anterior projection of the shell is not preserved.

Family BRANSONIIDAE Pojeta & Runnegar, 1976 Bransonia sp? Pl. 7, fig. 4 Discussion. — This large species is identified as a conocardiid by the shell structure, consisting of radial rods embedded within the PERMIAN BracHiopops AND Mo.tiuscs: YANCEY 313 shell wall of the valve, a unique conocardiid feature. Other features are not well preserved, and it is tentatively assigned to Bransonia on the basis of shape and probable lack of a hood, although hippo- cardiid affinities cannot be ruled out. This species is larger and more trigonal in form than A. langenheimi, and appears to be definitely ribbed, although weathering may have emphasized the strength of ribbing on exposed surfaces. Details of rostrum, anterior projection and interior are not known, but rostrum and anterior projection are probably relatively small. The shell is large, with a height and minimum length of 5 cm, and inflation of 4.5 cm, which makes this one of the largest species of conocardiids known. Occurrence. — Riepetown Formation, loc.

Nat. Sci., Proc. for 1870, p. 44. Clinopistha, McAlester, 1968, Geol. Soc. America, Mem. 105, pp. 20-21, pl. 4, figs. 1-16. Type species: Clinopistha levis (as Clinopistha radiata levis) Meek & Worthen, 1870. Diagnosis. — Medium-sized, subquadrate forms with an elon- gate anterior margin and a prominent external ligament on the short posterior margin. Discussion. — The type species of Clinopistha is similar to Nuculopsis in external form, particularly to the type species of Nuculopsis, N. girtyt. Both species are enlarged and elongated in one direction with umbonal areas offset from the center of the shell, both are well inflated, and both have a nearly smooth exterior with irregular fine growth lines. The two differ in that Clinopistha has an external ligament which is often preserved and when found is a diagnostic character to separate the two genera. Clinopistha has a larger shell which is not so extremely inflated as Nuculopsis and has 314 BULLETIN 303 a thin shell wall. The shell wall of Clinopistha is about 1/3 to 1/2 the thickness of the shell wall of Nuculopsis and is the easiest means of separating the two genera. Clinopistha is placed in the family Ctenodontidae on the basis of its external form and the possession of an external ligament. Pre- sumably the shell has taxodont dentition, but this has not been demonstrated with undoubted Clinopistha. The many illustrations of the type lot of Clinopistha that McAlester (1968) presented pro- vide no evidence of this. Most of the type lot are tightly articulated shells showing no dentition.

Soc. America, Mem. 105, pp. 20-21, pl. 4, figs. 1-16. Description. — Medium-sized, well-inflated, sub-rectangular shells; anteriorly elongate with a smoothly rounded extremity; flat- tened dorsal margin; sharply and smoothly rounded posterior mar- gin; large and raised external ligament on posterior slope; umbos prominent but not inflated; shell wall thin; ornament of fine con- centric growth ridges and furrows; and a few faint radial ribs on the posterior portion of the shell; dentition and hinge unknown. Discussion.— This species agrees in all observed characters with the type lot of the species (illustrated by McAlester, 1968) which is upper Carboniferous. The faint radial rib ornament is present, as in the type lot of the species, but is not as strongly de- veloped. The specimen described here is slightly longer than the average of the type lot but falls within the range of variation of the lot. This occurrence extends the range of the species and of the genus into the Permian, well up in the Wolfcampian Series. Ciriacks (1963) illustrated a more elongate, undescribed species of this genus as “Nuculopsis sp. a”, from a geologic horizon younger than the Arcturus Group. Occurrence. — Dry Mountain “lithosome”, Riepetown Forma- tion, loc. 1J-2, Dry Mountain, Nevada. Superfamily NUCULACEA Gray, 1824 Family NUCULIDAE Gray, 1824 Discussion. —Nuculids are common in late Paleozoic faunas, PERMIAN Bracuiopops AND Mo.tiuscs: YANCEY 315 but their taxonomy is unsettled because of the description of many new taxa since Schenck (1934) revised the family Nuculidae. Fol- lowing Schenck, the diagnosis of the family is: small, trigonal bi- valves with taxodont dentition and a resilifer, lacking a pallial sinus, and beaks posterior with a well-developed pseudo-lunule and poorly defined escutcheon. None of the Paleozoic forms are known to have a truly denticulate ventral margin. Upper Paleozoic species of the nuculids belong in the genera Nuculopsis, Nuculavus, and Quadratonucula. Both Nucula and Palaeonucula, which have been used by past workers for upper Paleozoic species, are post-Paleozoic. Small trigonal nuculids, which include most of the upper Paleozoic species in the family, belong in the genus Nuculavus (Chernyshev, 1947). The genus Nuculanella proposed by Tasch (1953) is clearly a synonym of Nuculavus. Nuculopsis (Girty, 1911) includes a small group of distinctive species with elongate form and thick shell wall. Quadratonucula (Dickens, 1963) is a small subquadrate form that is definitely a nuculid, although McAlester (1969) placed it in the family Mal- letiidae. This genus has been overlooked in previous studies and is probably fairly common. However, the majority of upper Paleo- zoic nuculid species belong in Nuculavus, which probably can be split into subgeneric groups. The recognized genera of upper Paleozoic nuculids, Nucwlopsts, Nuculavus, and Quadratonucula, differ greatly from each other and clearly belong in different phylogenetic stocks within the family, as well as being different from most younger genera within the family. Possible subdivision within the family was discussed by Dickens (1963), but he chose to follow Schenck’s (1934) informal groupings of genera. Difficulties in intrafamily classification are compounded by uncertain family limits as genera are shuffled from one family to another. Characters of importance in family classification are the nature of the resilifer, presence or absence of denticulate margins, shell thickness, and shell microstructure. Because a subdivision of the family for upper Paleozoic genera does not work well for groups of lower Paleozoic and post-Paleozoic genera, family subdivision is not attempted. The informal groupings of Schenck (1934) do not work well for upper Paleozoic genera in the family. 316 BuLLeTIN 303 Genus NUCULAVUS Chernyshev, 1947 Nuculavus Chernyshev, 1947, Akad.

Diagnosis. — Small, trigonal nuculids with concentric ornament of fine irregular growth lines, beak located a short distance pos- teriorly, resilifer small, open, shallow, and triangular. Discussion. — This genus includes the most common taxodont species of the upper Paleozoic. Species of this genus have been re- ported under the generic names Nucula and Palaeonucula which are post-Paleozoic genera and do not extend into the Paleozoic. Chernyshev’s (1947) description of Nuculavus as a new genus is the first available name for the group. There are many named species in this genus, whose relationships to each other remain to be worked out. Species of Nuculavus lived primarily in shallow environments, and usually in populations with great numbers of individuals. The genus is common in upper Carboniferous and lower Permian strata, but its older and younger limits have not been determined. Pre- sumably it ranges through most or all of the Carboniferous and Permian. Nuculavus levatiformis (Walcott), 1884 Pl. 7, figs. 6-10 Nucula levatiforme Walcott, 1884, U.S. Geol.

Palaeonucula levatiformis (Walcott), Yancey, 1969, Paleobios, No. 8, p. 6, figs. 18-20. Description. — Small, subtriangular shells, averaging about as high as long, with beaks situated posterior of center of hingeline; beak in some specimens close to posterior margin of shell, close to PERMIAN Bracuiopops AND Mo.tuiuscs: YANCEY 317 midpoint in others; outline of shell variable, imperfectly equilaterally triangular; well inflated with thickest part about 1/3 height below beaks; ornamentation subdued, consisting of many low concentric ribs, some individuals having a few irregular growth constrictions superimposed over these; pseudolunule sharply defined and large, enclosing a flattened area below the beaks and extending to ventral margins, with slight outward bulge midway between beaks and margins; taxodont dentition with about 12-15 anterior teeth and 9-10 posterior teeth including the small teeth under the beak; resilifer small but distinct, of triangular shape, shallow and flat in form with only a slight curvature on the ventral edge; individuals reaching 7 mm in height and 7 mm in length in Arcturus populations. Discussion. — The variation in external form in this species is large, and the height-length ratio ranges from 1:1.5 to 1.5:1. This is the most variable specific character, and variations in the other characters appear to be dependent upon the changes in dimension of the shell. The species is characterized by a moderately inclined beak which may be strongly inclined in a small proportion of individuals in a population. This species can be differentiated from most other species of Nuculavus by its subdued, less prominent beak, moderate inflation of the valves, and rounded extremities. In the available material, there are consistent regional differences within the species. Popula- tions from the Arcturus Group of the Ely area tend to have more ele- vated beaks, and, therefore, have a greater height-length ratio than others. In the populations from the Maverick Springs Range, the more elevated beaks are lacking and the concentric ornament is weak. All of the Arcturus populations differ from the Colorado Plateau populations in having a smaller average size and in having weaker concentric ornament. Also, the Colorado Plateau individuals tend to have slightly heavier, thicker shells. These are all infraspecific varia- tions and do not deserve formal designation. They indicate a trend of southward increase in size and thickness of shell, and increase in strength of concentric ornament. Nuculavus levatiformis is common in lower Permian strata of the western states and is the commonest taxodont species in those rocks. It occurs characteristically with biotas of shallow-water marine environments, including marginal marine environments, and 318 BuLLeETIN 303 preferred muddy substrates. Occurrence. — Many localities in the Pequop Formation and Loray Formation, Egan Range, Butte Mountains, Maverick Springs Range and Medicine Range, Nevada, and Arcturus Formation, Con- fusion Range, Utah. Nuculavus sp. A Pl. 7, figs. 11-14 Description. — Small to medium size, moderately to strongly inflated shells; beak and resilifer at highest point on tooth row; beak well elevated and slightly incurved; margins nearly straight on an- terior and posterior slopes, and with sharply curved anteroventral and dorsoventral extremities; tooth rows short but large, with about 10 teeth in the posterior row and 12 or more in the anterior row, some larger; resilifer dish-shaped with a rounded ventral margin, and projects ventrally into the shell; shell wall thick; adductor muscle scars and pallial line deeply impressed on large shells; orna- ment consisting of closely and regularly spaced concentric ribs; size reaching 11 mm in length and 10 mm in height. Discussion. — This species is larger and more robust than WN. levatiformis. Adult shells have nearly straight lateral margins rather than curved ones, and a thicker shell wall. NV. sp. A also has stronger tooth rows and larger dish-shaped resilifer, and a higher degree of inflation. It is clearly a distinct species from N. levatiformis, but the indifferent preservation of the available material and the lack of a growth series prevents a complete comparison. The shells of large individuals are readily distinct by virtue of their more prominent beaks, straighter lateral margins, and more angular extremities, but small shells occurring with them are hard to distinguish from small N. levatiformts. This species appears to be conspecific with specimens illustrated by Ciriacks (1963) as Nuculopsis sp. C. The specimen illustrated by him has a more rounded anterior margin but is otherwise similar. Occurrence. — Loray Formation, loc. UCMP D-5611, D-5612, Robinson Summit area, Butte Mountains, Nevada. Nuculavus sp. B Pl..7,, figs. 15k Discussion. — Two lots of poorly preserved specimens from the Murry Summit section in the Egan Range are similar to specimens described by Girty (1915) as N. wewokana. This is an extremely in- a PERMIAN Bracuiopops AND Motiuscs: YANCEY 319 flated species which has strongly incurved beaks and a trigonal outline. Not enough specimens are available for study, but it does not appear to intergrade with N. levatiformis. The interiors and hinge are not known. There are a large and well-defined pseudo- lunule and an escutcheon on the dorsal margin. The posterior area contains a small pair of inner escutcheon ridges curving from the beaks to the hingeline just below the beaks. This species differs from NV. wewokana of the Wewoka Formation in having no earlike projections within the pseudolunule and escutcheon (noticeable on the specimens Girty illustrated), and has more rounded beaks. This species is closely related to N. wewokana and is part of a distinctive stock within Nuculavus. Both the Arcturus specimens and N. wewokana appear to have inner escutcheon ridges. These ridges are best developed in species of Polidevcia and are only oc- casionally present in species of Nuculavus. Nuculavus sp. B is found in shallow-water, normal marine de- posits. Occurrence. — Pequop Formation, loc. UCMP D-5535; Loray Formation, loc. UCMP D-5539, Egan Range, Nevada. Genus QUADRATONUCULA Dickens, 1963 Quadratonucula Dickens, 1963, Australia Bur. Min. Res., Geol. & Geophysics, Bull. 63, p. 32, pl. 1, figs. 16-24. Quadratonucula Dickens, McAlester, 1968, Geol. Soc. America, Mem. 105, pp. 49-50, pl. 14, figs. 1-9. Type species: Quadratonucula australiensis Dickens, 1963. Description. — Small to medium size, subquadrate to ovoid; moderately inflated; dorsal margin more flattened than arched, with beaks nearly centrally located, and umbos slightly incurved towards the tooth rows; tooth rows short and containing 5-10 small teeth, with one tooth row shorter than the other; a small resilifer present under the beak; two large adductor muscle scars, near the anterior and posterior extremities, and about four small muscle scars in the beak area; shell may be slightly flexed; shell nearly symmetrical in two planes, one plane between the valves and the other cutting from the dorsal to ventral margins at 90 degrees to the first plane. Discussion. — The presence of a resilifer in the shell is demon- strated here, though both Dickens (1963) and McAlester (1968) 320 BuLLeETIN 303 described the genus as lacking one. It is small, directly underlies the beak, and has a dish shape. Both adductor muscle scars are present on the Arcturus Group material and are both slightly impressed and rounded. Determining the orientation of this nuculid is especially difficult, and Dickens and McAlester chose opposite directions in their descriptions of the genus. Bradshaw and Bradshaw’s (1971) method of using dentition to determine orientation cannot be applied because of similar tooth size in both rows. A comparison with Deceptrix (which has similar form) suggests that the shorter tooth row of the hinge is anterior, which agrees with the orientation of McAlester (1968). There is a slight anterior inclination of the beak, and the anterior end is slightly shorter than the posterior. The shell features of this genus are typically nuculid, and it be- longs in the Nuculidae without doubt. The assignment of Quad- ratonucula to the family Malletiidae in the “Treatise of Invertebrate Paleontology, Part N,” by McAlester (1969) is hereby changed. The unique symmetrical proportions of the shell are derived by slight changes in the geometry of the shell and not by the loss or addition of characters. The differences in appearance from many other nucu- lids are more apparent than real, as a result of the symmetry im- posed on the valves, although this symmetry is not perfect. It is similar to the Devonian genus Deceptrix, to which it may be related. Quadratonucula stella, n. sp. Pl. 8, figs. 1-6 Description. — Small, nearly symmetrical nuculids; reaching 15 mm in length and 12 mm in height; moderately inflated — perhaps not more than 3-4 mm per valve; slightly, but not always, produced on the posterior margin; beak moderately incurved, often inclined slightly towards the anterior, this inclination more pronounced on the inner surface of the beak (as seen on the internal molds) than on the external surface; two tooth rows of nearly equal length, with about six teeth on the anterior row, and eight teeth on the posterior row; small resilifer of dish shape located directly under the beaks; adductor muscle scars of ovoid shape and impressed on adult shells, located half way up the height of the shell; about four tiny muscle scars impressed on the inner surface of the beak; pallial line non- sinuate; ornament of closely set, weak irregular concentric growth ridges only. PERMIAN Bracuiopops AND Mo.tiuscs: YANCEY S2il Discussion. — This species is different from the type species in a number of details of shape and tooth rows. It differs in having a more nearly symmetrical beak, in being more rounded in form, and in having nearly equal tooth rows, with fewer teeth in them. It is also much larger. The average size of specimens examined is about 10 mm in length, about twice the size of Q. australiensis. Both species are known only from silty sediments which probably accumulated in the same general environment — one of quiet, deeper water deposition.

Type species: Nuculopsis girtyt Schenck, 1934 (= Nucula ventricosa Hall, 1858). Diagnosis. — Small to large nuculids that tend to have a sub- quadrate form, thick shells, and a smooth ventral margin and lack definite concentric ribs. Discussion. — Girty (1911) erected this genus for nuculids which he believed to have an external ligament and anteriorly directed beaks. Schenck (1934) negated these two assumptions but retained the genus and placed it securely within his newly revised Nuculidae. He retained the genus for Paleozoic nuculids with smooth ventral margins lacking definite concentric ribs. They tend to be elongate or subquadrate, and to have thickened shell walls, charac- ters also noted by Girty (1915). Nuculopsis is similar in external form to the genus Clinopistha which is not a nuculid. Clinopistha possesses a true external ligament, 322 BULLETIN 303 has a thin shell wall, and is easily separated from Nuculopsis on these characters.

Non Nuculopsis girtyi Schenck, Bird, 1968, Bull. Amer. Paleont., vol. 54, No. 24 Oseps Lsi7epliel stip eds Description. — Small, equivalved taxodonts, well inflated, with a roughly rectangular shape formed by the parallel alignment of the dorsoanterior margin and ventral margin; beaks prominent and projecting slightly posteriorly; escutcheon well formed just below beaks, short and wide; faint pseudolunule developed anterior to beaks on well-preserved individuals; true lunule lacking; dentition taxodont; each valve thick walled, about 1.0-1.5 mm in thickness for full grown individuals; ornamentation lacking except for fine growth lines, and faint semiregular but occasional growth constrictions; posterior margin produced, with protruding extremity small and rounded; anterior extremity large and widely rounded; interior characters not seen. Discussion. — The Arcturus Group specimens appear identical to typical NV. girtyi, especially as illustrated by Girty (1915). The diagnostic characters include the ventricose shape, the nearly paral- lel top and bottom margins, and the sharply rounded posterior ex- tremity that is sometimes set off from the ventral margin by a slight groove on the shell. Nuculopsis girtyi is similar to Nucula gibbosa Fleming, 1828, from the Carboniferous of Scotland. Schenck (1934) suggested that these two may be conspecific, and if this proves to be true the species will bear Fleming’s earlier name.

PERMIAN BraAcHiopops AND Motiuscs: YANCEY 323 Description. — Small, subquadrate taxodonts; well inflated with prominent beaks inrolled towards the hinge and projecting pos- teriorly; shell wall relatively thick; anterior dentition consisting of many small teeth; posterior dentition not seen; posterior margin produced, with a tightly rounded extremity; anterior margin widely rounded; irregular growth constrictions on shell, but surface orna- ment unknown; other features unknown. Discussion. — Individuals questionably assigned to this species are close to the types of Nuculopsis darlingensis (in outline and in- flation), but they are not well enough preserved for positive identi- fication. On portions of the hingeline where the teeth can be ob- served, the teeth are identical both in size and number with those of the types of the species. The greatest difference is the stronger pos- terior projection of the beaks of the Arcturus specimens. The Arc- turus specimens and Australian specimens are closely related, and further collecting to determine the character of the hinge and the average position of the beak is needed to clarify the identification. The thick shell wall clearly places the species in the genus Nuculop- sis. Dickens (1963) noted that Nuculopsis darlingensis was found commonly in yellowish brown clayey matrix, similar to that of the Arcturus Group specimens. Occurrence. — Dry Mountain “lithosome”, Riepetown Forma- tion, loc. 1J-2, Buck Mountain, Nevada. Superfamily NUCULANACEA Adams & Adams, 1858 Family MALLETIIDAE Adams & Adams, 1858 Discussion. — There is a fairly large group of Paleozoic taxo- dont bivalves similar to Palaeoneilo which form a natural family grouping and are placed in the family Malletiidae. The Paleozoic genera are usually elongate, often with one or two radial grooves in the shell, have taxodont dentition with one tooth row much shorter than the other, and lack a resilifer. It is assumed that they have an external ligament, but this is yet to be proven. The Paleozoic genera are unlike modern genera in the family and do not appear to be closely related.

America, Mem. 105, pp. 16-17, pl. 20, figs. 1-17. Type species: Anthraconeilo taffiana Girty, 1911 (= Leda oweni McChesney, 1859). Description. — Small, thin-shelled taxodont bivalves of ovoid shape; having a raised and incurved beak, pointed towards the shorter end, located near the short end of the valve; shells inequi- lateral; margins smoothly rounded; dentition consisting of many small chevron-shaped taxodont teeth, about 20-30 on the long tooth row and about 10 on the short tooth row; ornament consisting of fine, regular, concentric ribs developed parallel to the growth lines; other features unknown. Discussion. — There is much discussion on the relationships and nature of this genus, largely because many critical characters are not adequately known. Girty (1915), in his description of the genus noted that an internal resilifer was not seen but was expected to be found. Unfortunately, no evidence of attachment for an internal or external ligament has been found, nor has this feature been determined in any of the closely related genera. Murphy (1966), after looking at many specimens of the genus, concluded that it lacked a resilifer, and that it possessed external grooves for a liga- ment, but did not illustrate any external grooves. On all specimens I have examined referable to the genus there is no evidence of an escutcheon, and no trace of external grooves. The hinge is thickened under the beak and along the short tooth row, but the teeth do not extend completely across the thickening, leaving a flat, barren shelf along the ventral margin of the hinge. This can be seen on internal molds as paired grooves parallel to the hingeline. This shelf may have functioned as a resilifer. Murphy (1966) suggested that Anthraconeilo and Palaeoneilo are synonymous, but this is doubtful, and Anthraconeilo is retained as a separate genus.

Description. — Small to moderate size taxodont bivalves of PERMIAN BrRAcHIopops AND Mo..iuscs: YANCEY 325 nearly oval shape, having a small beak located closer to the posterior end of the shell than the midpoint; beak incurved and slightly pointed posteriorly; moderately inflated; lacking radial grooves; an- terior end of shell slightly elongated; hingeline consisting of many small, chevron-shaped teeth, with about 20-30 teeth on the anterior tooth row, and 5-10 on the posterior row; posterior teeth at least as large as the anterior teeth, and located on a wide hingeline plate that has a smooth extension on the ventral side of the tooth row; open space, developed below beak, consisting of a smooth area on the hingeline plate; shell wall thin to medium thickness; ornament of fine, regular concentric ribs. Discussion. — The hinge structure of the species is well dis- played on one individual, where the strong character of the teeth on the posterior tooth row is shown. The tooth row is also unusual in that there is a smooth rim of material on the ventral side of the tooth row where the teeth are not developed beneath the anterior tooth row. This smooth surface on the hinge plate extends under the beak where it is wider because of the narrowing tooth rows at this point, and the result is a triangular depressed space between the tooth rows. This may have functioned as a resilifer. This species is known from the Riepetown Formation of late Wolfcampian age and from the Meade Peak Formation and Gran- deur Formation of the Park City Group of Leonardian age.

Pl. 8, fig. 16 Description. — Small, ovoid shells with a nearly terminal beak, and a short, straight hingeline; extremity away from the beak rounded or somewhat angulate on the ventral border; dentition un- known; thin shell wall; ornament consisting of fine, regular, con- centric ribs. Discussion. — This species is too poorly preserved to identify properly, and not enough of the hinge is known to properly assign it generically. The closest comparison is to the species Edmondia ? 326 BULLETIN 303 phosphatica Girty, illustrated and described by Girty (1910) and Ciriacks (1963). However, E. ? phosphatica is more elongate and has a more prominent beak. Inasmuch as the hinge of this species and that of E. ? phosphatica are not known, a proper evaluation of their relationships cannot be made. Occurrence. — Dry Mountain “lithosome”, Riepetown Forma- tion, loc. 1J-2, Ruby Range, Nevada. Family NUCULANIDAE Adams & Adams, 1858 Diagnosis. — Nuculoid bivalves with elongate form, long tooth rows with resilifer beneath the beak below the juncture of the tooth rows; most genera having regular strong concentric ornament, often at a slight angle to the growth lines. Discussion. — A large and diverse group of genera that appear to represent several stocks of taxodonts are presently assigned to the family Nuculanidae. In the upper Paleozoic there is a fairly distinct group of nuculanids, including the genera Polidevcia, Phestia, Gir- tyana, and Glyptoleda belonging in one stock, and questionably in- cluding the genus Paleyoldia. Many genera in the group possess the characteristic ornament pattern so well-developed on some modern species of Nuculana and Yoldia. This consists of a series of concen- tric step ribs, regular and sharp in form, developed at an angle to the growth lines, with the crest inclined towards the beak. Each step rib has a sharp crest, and a short steep dorsal slope and a longer, lower ventral slope (PI. 9, fig. 9, as well as illustrations in Chronic, 1952, and McAlester, 1968). Subfamily PHESTIINAE Logan, 1967 Diagnosis. — Well-inflated nuculanids with a slightly to greatly produced posterior margin, commonly with umbonal ridges on the posterior portion of the dorsal margin; having well-defined escutch- eon; short to long tooth rows with many teeth, and a triangular or dish-shaped resilifer; having regular, sharp concentric ribbing de- veloped at a slight angle to the growth lines, often becoming ob- solete on posterior portion of shell; an entire pallial line; most genera have an internal thickened ridge extending ventrally from beak. Discussion. — There has been considerable discussion on the validity and limits of Paleozoic genera in the family Nuculanidae. Such problems can only be resolved by further work, but my experi- PERMIAN Bracuiopops AND Mo.tuiuscs: YANCEY S27, ence has been that all genera proposed are valid. Logan (1967), presented a good summary of the problems associated with classifica- tion of the taxodonts. Lintz (1958) and Logan (1967) discussed the characteristics of nuculanids that belong in the Phestiinae. This subfamily is characterized by an elongate form, a triangu- lar or dish-shaped resilifer, and an entire pallial line. The typical nuculanid ornament is known to be present in Polidevcia, Phestia, and Paleyoldia, and the internal ridge is known to be present in Polidevcia, Phestia, and Girtyana but is not present in Paleyoldia.

Soc., Mon., No. 518, vol. 121, p. 43-44. Phestia Chernyshev, McAlester, 1968, Geol. Soc. America, Mem. 105, p. 43, pl. 34, figs. 3-6. Type species: Leda inflatiformis Cherynshev, 1939. Diagnosis. — Small nuculanids with a slightly to moderately produced posterior extremity; having a height nearly equal to length; beaks incurved but not projecting lengthwise; having typical nuculanid ornament over most of the valve; triangular resilifer; posterior tooth row half as long as anterior row; lacking or having a small inner escutcheon ridge on escutcheon. Discussion. — This genus is poorly known from its original descriptions and little information has disseminated to English speaking workers about the characteristics of this Russian genus. It appears to be far more common in the eastern European areas than in the Americas or Australia where mollusc-dominated normal marine faunas are common. In these areas, and in Europe, the name Phestia has been haphazardly applied to material known only from internal molds. Most of the species described by Chernyshev are small, and the genus can be typified by small taxa. Because of the difficulty in separating species of Phestia from species of Polidevcia, many workers place the two genera in syno- nymy. Logan (1967) summarized in English the differences between Phestia and Polidevcia from Chernyshev’s original description. Ex- cept for the presence of a resilifer in Polidevcia, the original diagno- sis is still the best published guide to separating the two genera. 328 BuLLeTIN 303 They can be clearly separated in the American species as well as the Russian species. Species of Phestia are smaller, with little posterior elongation, have a much shorter posterior row of teeth, and a tri- angular resilifer. Although not conspicuous, a short subdued pair of inner escutcheon ridges may be present. Polidevcia has rows of teeth of subequal length, and a dish-shaped resilifer. Other features are similar between the two genera. There are enough differences in characters to justify separating the two forms, with Phestia in- cluding mostly species of small size, and Polidevcia including species with an elongate posterior extremity. The best characters for separating the genera are the length of the tooth rows, and the shape of the resilifer. Phestia perumbonata (White), 1880 Pl. 9, figs. 1-5 Nucula perumbonata White, 1880, U.S . Geol. Surv., 12th Ann. Report, Contr. Pal., No. 6, p. 136, pl. 34, figs. 7a-b. Description. — Small nuculanids with a height almost equal to length, and slightly produced posterior extremities; beak located centrally on the dorsal margin, and slightly directed posteriorly; moderately inflated; outline broadly and smoothly rounded every- where except on the posterior extremity which is sharply rounded; typical nuculanid ornament of many concentric ribs set at an angle to the growth lines; ribs closely spaced; well-defined escutcheon with a slightly protruding central portion consisting of the escutch- eon ridges; tooth rows continuous and composed of chevron-shaped teeth, about five on the posterior row and 10 on the anterior row; resilifer present below the beaks and of triangular shape and directed anteriorly; inner thickening ridge below the beak of the shell; pallial line entire. Discussion. — This species has been unreported since the first description of it, and has undoubtedly been overlooked because it was confused with juveniles of Polidevcia or with Nuculavus. White’s description was short and based on a single articulated specimen, so many characters of the shell were never described. In particular, the internal characters have not been recorded, and the nuculanid-type ornament has not been described. White (1880) gave two dia- gramatic drawings of the articulated holotype. Etched valves are illustrated here to show the internal and external features. PERMIAN BRACHIOPODS AND Mo.tiuscs: YANCEY 329 White’s illustration of the holotype shows a greater resem- blance to Nuculavus than the species has. The drawings probably show the beaks to be higher than they are. I have not examined the holotype, but the biota of the Kaibab Formation includes a small species of Phestia that compares closely with the specimen White described as Nucula perumbonata, and there is good reason to use his name for it. No nuculanid species of this size has been otherwise reported in North America. The species is known only from the Loray Formation of middle or late Leonardian age, and the Kaibab Formation of late Leo- nardian or earliest Guadalupian age. Occurrence. —Loray Formation, loc.

Diagnosis. — Large, elongate nuculanids with a strongly pro- duced posterior margin; a long well-defined escutcheon with a strong set of inner escutcheon ridges; long tooth rows of subequal length, continuous over a rounded dish-shaped protruding resilifer. Discussion. — Both Chernyshev (1951) and Lintz (1958) pro- posed a new generic name for taxodonts of the same type which had previously been referred to as Nuculana in upper Paleozoic deposits. Chernyshev’s description is earlier, and although Lintz (1958) made a distinction between the two generic proposals on the basis of Chernyshev’s statement that the type species of Polideucia lacks a chondrophore (resilifer), this appears to be an unwarranted guess on the part of Chernyshev, and the two genera have been synonym- ized by later workers. In the description of Culunana, Lintz (1958) separated Culu- 330 BuLLeTIN 303 nana from Nuculana on the basis of a continuous row of teeth over the resilifer which Nuculana often doesn’t have, and the presence of rectangular teeth on the posterior tooth row. The statement about tooth form was a mistake, and as far as is known all nuculanids have chevron-shaped teeth. A better means to distinguish the two genera is the shape and size of the resilifer, and the fact that Polidevcia has more strongly incurved beaks. The reason for Lintz’s mistake about the tooth form in Poli- devcia bellistriata is that the teeth in this species have an unequal chevron shape, with one arm of the V much longer than the other. In poorly preserved material the teeth could appear to be rectangu- lar rather than chevron-shaped. On the anterior tooth row, the lengthened arm is ventral and the bend of the V is near the outer surface of the shell, while on the posterior tooth row the lengthened arm is dorsal and the bend of the V is near the inner edge. This characteristic tooth form is also present in Polidevcia obesa, but in that species the tooth is closer to a true V-shape. It is a common characteristic that in etched silicified collections containing nuculids and nuculanids, the species of Polidevcia are consistently more poorly preserved than the species of Nuculavus. Often when Nuculavus is excellently preserved, the Polidevcia are present as broken fragments or partly silicified internal molds with pieces of shell adhering to them. Because these come from the same sample it is clear that the two groups have been altered differently during diagenesis, and probably had different shell structure (Newell & Boyd, 1970, pp. 239-241, reviewed this problem in bivalves). Polidevcia appears to have been less stable and probably had a shell structure with large amounts of aragonite.

Hist., Bull., vol. 125, Art. 1. p. 42, pl. 4, fig. 1-3. Discussion. — This species has been well described by other PERMIAN Bracuiopops AND Mo.uiuscs: YANCEY 331 authors. Excellent descriptions are given in White (1880) and Chronic (1952), especially the account by Chronic (1952) who gave measurements on a growth series of a population that was collected from a locality geographically and stratigraphically close to the type locality of the species. Her illustrations of adult forms of the species are excellent. P. obesa is distinguished from other species in the genus by its strongly attenuated and elongated posterior extremity, which is usually slightly to moderately upturned, and the subcentral location of the beaks. The beaks are conspicuously directed posteriorly and nearly centrally located. In addition, the posterior part of the dorsal margin is moderately concave and the ventral margin is smoothly convex. The species is similar to P. pandoraeformis of the lower Carboniferous (Driscoll, 1966) and appears to be descended from it, although upper Carboniferous specimens of this lineage are not known. P. obesa differs from P. pandoraeformis principally in its lower height relative to length. It can be distinguished from P. bellstriata by its more elongate posterior extremity and distinctly posteriorly directed beaks. Within the species there is definite variation in morphology from one population to another, mostly among smaller specimens. This variation is expressed in the amount of upward inclination of the posterior extremity, and the curvature of the ventral margin. These are interrelated characters, and a small variation in the posi- tion of the posterior extremity produces a greater difference in pro- file. Smaller specimens with a less curved posterior extremity can be confused with other species, but the more centrally located beak reveals their identity. These develop typical form upon maturity. P. obesa has been reported from the upper part of the Arcturus Group, Kaibab Formation, San Andres Formation, and throughout the Phosphoria Group. This gives a geologic range from the base of the Leonardian Series (Riepetown Formation, Maverick Springs Range) to well within the Guadalupian Series (Phosphoria Group). The species appears to be restricted to the middle Permian. It is known only from deposits of shallow-water environments and in- habits a variety of environmental conditions. Occurrence. — Many localities in the Arcturus Group (Riepe- town, Pequop and Loray formations) of the Egan Range, Butte 332 BULLETIN 303 Mountains, Maverick Springs Range; Medicine Range, Nevada; Arcturus Formation, Confusion Range, Utah, but most abundant in the Loray Formation.

Discussion. — This species has been well described by Girty (1915), Lintz (1958), and Driscoll (1966), and the reader is re- ferred to these sources for a complete description. The species is common in the upper Carboniferous and lower Permian of the North American midcontinent. Its occurrence in most lower Permian deposits of the western states has been overlooked because P. obesa is normally the most abundant Polidevcia in these horizons. Polidevcia bellistriata is distinguished from P. obesa and all other species in the genus by its rounded and blunt posterior ex- tremity which is not much produced. Its beaks are conspicuously incurved and only slightly pointed posteriorly. It has a more com- pact shape than other species. The internal structures of the species are poorly known. Both Lintz (1958) and Driscoll (1966) described the species as having rectangular rather than chevron-shaped teeth on at least part of the anterior tooth row. However, illustrations of the type of the species by McAlester (1968) show the tooth row to be composed of chevron- shaped teeth, the normal condition in all nuculoid bivalves. On the illustrations of Driscoll (1966) it is clear that the portion of the tooth row near the beak has elongate teeth that are unequal chevrons (see discussion of tooth shape under genus description). Descrip- tions of rectangular teeth appear to have been based on observa- tions on weathered, leached specimens; well-preserved material shows modified chevron tooth form. PERMIAN Bracuiopops AND Mo.iuscs: YANCEY 333 The stratigraphic ranges of P. bellistriata and P. obesa are separate, and within the Arcturus Group overlap only in the Riepe- town Formation in the Maverick Springs Range. P. bellistriata ranges from the lower Atokan Series of the upper Carboniferous through the Wolfcampian Series of the lower Permian (Driscoll, 1966). The highest occurrence in the Arcturus Group is in the Riepe- town Formation in the zone of Schwagerina linearis, approximately Wolfcampian-Leonardian boundary in age. P. bellistriata inhabited both deep and shallow environments, preferring a fine-grained substrate and quiet water conditions. On the average it inhabited deeper waters and quieter water conditions than P. obesa. Occurrence. — Riepetown Formation, loc.

Pl. 9, figs. 14-15 Description. — Polidevcia of medium-size with pointed and moderately upturned posterior elongation; ventral margin straight beneath beaks, and upturned on the posterior extremity; anterior margin steep and little curved, curving sharply to join the ventral margin; beak located near the anterior extremity, strongly incurved, and slightly curved posteriorly; escutcheon large, containing pair of large, long inner escutcheon ridges, and an inner ridge formed by upturned edges of valves; well inflated; with typical nuculanid ornament; reaching 3 cm long, 1.5 cm high, and 1 cm thick; internal features unknown. Discussion. — This species can be easily separated from P. obesa and P. bellistriata by the position of the beak near the an- terior end of the shell and can be further distinguished by the nearly straight ventral margin in the anterior end, and the shape of the posterior elongation, which is neither as pointed nor as upturned as in P. obesa. Also, the inner escutcheon ridges are stronger than in P. obesa. P. arctura is uncommon, but occurs in the same quiet water en- vironment as P. bellistriata. The character of the posterior ex- tremity is approximately intermediate between P. obesa and P. 334 BULLETIN 303 bellistriata, but the position of the beak differs greatly from either species.

Description. — Medium-sized nuculanids with coarse concentric ribs extending over most of valves; short posterior elongation having a blunt and openly rounded termination; valves about 2/3 as high as long; moderately inflated as in most nuculanids; anterior three- quarters of valves possessing thin, high concentric ribs separated by narrow or wide flat spaces; sharp, raised ribs stopping short of postero-dorsal surface; spacing of sharp, raised ribs variable; an- terior and posterior tooth rows containing about 10 and 15 teeth respectively, teeth of chevron shape, and large throughout tooth rows; small dish-shaped resilifer present under the beaks; strong adductor muscle scars and single internal ridge extending from the umbo. Discussion. — This genus is distinct and can be easily separated from Polidevcia, Phestia, and Glyptoleda on the basis of the strong, sharp, raised ribs on the anterior portions of the valve that do not extend onto the posterior end of the valve. In shape it can be con- fused with young specimens of other nuculanids, but the ornament is distinctive. The dentition, resilifer, and internal ridge are diag- nostic of the nuculanids. The outline of Girtyana is close to that of some species of Phestia (such as the type species), but the charac- teristic ornament will reliably separate the two genera. Also, Girtyana has large teeth and may lack an escutcheon. PERMIAN BrRAcHIOPODS AND Mo.uiuscs: YANCEY 335 4 Girtyana stellara, n. sp. Pl. 10, figs. 1-4 Description. — Medium-sized nuculanids with a moderately produced and bluntly rounded posterior extremity; incurved beak without significant turning of the beak anteriorly or posteriorly; moderately inflated; taxodont dentition, with about 15 teeth on the posterior row, anterior row unknown, and a small resilifer directly below the beak; external ornament of large, sharp, raised ribs sepa- rated by a small space, extending almost but never completely to the posterior extremity of the valve or on the postero-dorsal surface; a conspicuous boundary between the ribbed and non-ribbed surfaces running diagonally from the beak to the postero-ventral margin; sharp ribs running slightly oblique to growth lines; shell wall thin; other features unknown. Discussion. — This species can be distinguished from the type species by its more closely spaced sharp concentric ribs and its blunter posterior extremity. Morse (1931) illustrated two species of Girtyana (as Leda arata and L. jllsoni) that demonstrate a con- siderable range of variation in the development of the ornament in the genus. The ornament may be strong and of few ribs or be dense and more subdued. G. stellara differs considerably from the type species, G. honessi, in having a much thinner shell wall and smaller teeth, as well as more numerous concentric ribs. Girtyana stellara is known from the early Permian of Nevada (Riepetown Formation — upper Wolfcampian Series). It has been collected only from fine-grained shales. The species lived in quiet waters perhaps with considerable depth range. Occurrence. — Dry Mountain “lithosome”, loc. 1J-2, Buck Mountain, Nevada. Numbered specimens. — Holotype USNM 245176, paratypes USNM 245177-245180, all from loc. 1J-2, Buck Mountain, Nevada. Etymology. — Refering to the star Arcturus in the constella- tion Bostes. Subclass PTERIOMORPHA Beurlen, 1944 Order ARCOIDA Stoliczka, 1871 Superfamily ARCACEA Lamarck, 1809 BULLETIN 303 >) Oo ON Family PARALLELODONTIDAE Dall, 1898 Diagnosis. — Elongate, well-inflated arcids with beaks located nearer to anterior end of shell; broad diverging ligamental area con- taining duplivincular ligament; simple arcid dentition of few or several small oblique teeth on anterior end of hinge and long laterals subparallel to hingeline on posterior end of hinge. Discussion. — This is primarily a Mesozoic family. During the Mesozoic the group diversified and included a large number of genera, which have been combined into two subfamilies containing several “groups” of genera. Permian species are similar to Mesozoic species but show much less diversity, while pre-Permian species show considerable variation from the Mesozoic types. Newell (1969) suggested that the Parallelodontidae were derived from the Cyrto- dontidae during the Paleozoic, and pre-Permian species appear to include forms transitional between the two families. Species of Parallelodon from the lower Carboniferous Marshall Formation illustrated by Driscoll (1961) have parallelodontid dentition but are transitional to the cyrtodontids in shape and other characters. Nearly all Permian species in the family have been referred to the genus Parallelodon which is given a geologic range extending from the Ordovician to the Jurassic (Newell, 1969). However, most of them do not belong in the genus Parallelodon s.s., and should be reassigned to the Grammatodon group of genera and subgenera. Recent reviews of this family by Driscoll (1961) and Logan (1967) recognized the need for revision of the family, especially the Paleo- ZOIC species. Genus GRAMMATODON Meek & Hayden, 1861 Subgenus COSMETODON Branson, 1942 Beushausenia of Arkell, 1930 (mon Cossmann, 1897), Geol. Mag., vol. 67, p. 303. Cosmetodon Branson, 1942, Jour. Paleont., vol. 16, No. 2, p. 248. Type species: Arca keyserlingu d’Orbigny, 1850. Description. — Shell elongate and trapezoidal; strongly in- flated, and without byssal gape; beak located near anterior end of shell, and incurved; ligamental area smooth and wide with duplivin- cular ligament; hinge consisting of several anterior teeth of small size radiating upward and laterally from a point under the beak, including two small but strong teeth on anterior end of hinge, and PERMIAN BrAcHIopops AND Mo.iuiuscs: YANCEY S35) two or three long lateral teeth along posterior part of hinge; point of greatest projection of valve on postero-ventral corner. Discussion. — Grammatodon (Cosmetodon) is the best name for most if not all Permian arcid-type clams, and the use of the name Parallelodon should be discontinued. The hinges of Permian species contain a radial array of teeth under the beak which is a character of Grammatodon (Cosmetodon) and related subgenera and not of Parallelodon. Parallelodon can be distinguished as a separate genus on the basis of having a nearly terminal beak and many large inclined teeth [Arkell (1930), included illustrations of the type species]. I have reservations about accepting the interpretation that the anterior teeth of Parallelodon all converge to a point slightly above and ahead of the beak, being more or less en echelon alignment, but the genus is valid on the basis of other characters.

America, Mem. 89, pp. 51-52, pl. 6, figs. 10a-b (not 8-9c). Description. — Elongate and trapezoidal arcids; well inflated; without byssal gape; anterior margin nearly perpendicular to dorsal and ventral margin, and rounding smoothly into ventral margin; ventral margin slightly curved except for short straightening in the middle; posterior margin directed back towards anterior end, with slight sinus; no posterior ear developed; growth lines prominent and regular; unworn shells covered with fine radial ribs, at least on the posterior portion of the shells, ribs of constant strength throughout growth of shell; hinge containing several tiny and curved teeth radiating out from a point directly below beak, with some stronger and nearly horizontal on anterior end of hinge, and with two or three long horizontal lateral teeth on posterior end of hingeline; ligamental area smooth and wide with a duplivincular ligament; beaks located near anterior end of shell and incurved; slight groove on crest of inflated beak area on young specimens. Discussion. — This species is common in Permian deposits of the western states, and was well described by Chronic (1952). The 338 BULLETIN 303 only important character not mentioned in her description is the presence of faint radial ribs on the shell, which stay the same strength throughout growth. These apparently are easily eroded off during the lifetime of the animal, or before burial, and ordinarily are not seen on fossil material. G. (C.) politus can be distinguished from other species in the genus by the faint radial ribs of constant strength, by the straight or nearly straight posterior margin, and by the anterior margin that is nearly perpendicular to the dorsal and ventral margins. The species is known fom the Capitan Formation and Delaware Mountains Formation of Guadalupian age, and the Kaibab Forma- tion and Fort Apache Member of the Supai Formation of Leonardian age, and the Loray Formation of Leonardian age. The species oc- curs in a variety of shallow-water substrates in fully normal marine conditions. It probably was an exposed nestler or an epifaunal form, because it often shows evidence of abrasion and abrupt growth stop- pages in the shell, probably due to periods of rough water conditions. Occurrence. — Arcturus Formation, loc. UCMP D-5586, Con- fusion Range, Utah; Loray Formation, loc. UCMP D-5518, D-5535, D-5539, D-5545, D-5546, D-5550, D-5555, Egan Range, Nevada. Order MYTILOIDA Ferussac, 1822 Superfamily PINNACEA Leach, 1819 Family PINNIDAE Leach, 1819 Diagnosis. — Elongate, trigonal shells with pointed beak and smoothly rounded posterior extremity; mostly equivalved; large pos- terior gape; hinge edentulous, ligament subinternal and extending along entire hinge margin; shell wall generally thin, and with nacreous layer developed in part; shell wall moderately flexible when thin; two well-developed muscle scars in anterior half of shell; orna- ment various. Discussion. — This family has been common in shallow marine environments since the Carboniferous Period and has changed little in shell features or life habits since that time. The large size of the shells of many species, and their relative fragility (which results in crushing during burial) makes collecting them difficult and keeps them from being adequately studied. Genus MEEKOPINNA, new genus Type species: Aviculopinna americana Meek, 1867. PERMIAN BraAcutopops AND Mo.tiuscs: YANCEY 339 Description. — Generally small, elongate, narrow pinnids; hinge line thickened on each valve by roll of shell material; beaks sub- terminal but located close to anterior end; shell with characteristic narrow, sharp regular growth lamellae; growth lines nearly parallel to ventral margin and becoming straightened or slightly flexed on posterior margin, there joining hingeline at nearly a right angle; shell moderately inflated and thin shelled. Discussion. — Arcturus pinnid species belong in two species groups: one type has small, sharp, regular growth lamellae, and the other type has a smooth shell without significant ornament. These two types are common in Carboniferous and Permian strata in North America and are generically distinct but have been placed together in Aviculopinna, an all encompassing genus. Meek (1864) erected Aviculopinna, with “Pinna prisca Munster = Avicula pinnaeformis Geinitz” as type species, for pinnids with subterminal beaks. The type referred to by Meek has a strongly subterminal beak and faint radial striae. Meek later (1867) described Aviculopinna americana and contrasted it to A. pinnaeformus by stating that A. americana possessed sharp, regular growth lamellae, had no trace of radial striae, and had a beak that was more nearly terminal in position. Pinnids with narrow elongate shells having regular, sharp growth lamellae lack a suitable generic name, and Meekopinna is proposed here to include this group. The generic name Pteronites, (a genus distinct from Avicu- lopinna, despite the synonymy by Cox and Hertlein, 1969), is not available for americana-type pinnids. Pteronites is based on a lower Carboniferous species that differs greatly from Meekopinna in shell form, having a strongly curved ventral margin, and much less elon- gate shape. Pteronites is almost transitional to pteriacean shell form. It does have regularly spaced concentric shell ornament and may be related to Meekopinna but is distinct. Species of the genus Meekopinna occur mostly in fine-grained sediments, usually of terrigenous or partly terrigenous composition, and rarely occur in coarse-grained sediments or in high energy en- vironments. This preferred association with fine-grained terrigenous sediments occurs consistently through the Carboniferous and Per- mian. 340 BuL_etin 303 Meekopinna sagitta (Chronic), 1952 Pl. 10, figs. 10-11 Aviculopinna sagitta Chronic, 1952, Geol. Soc. America, Bull., vol. 63, No. 2, p. 141, pl. 6, fig. 10. Aviculopinna sp. b, Ciriacks, 1963, Amer. Mus. Nat. Hist., vol. 125, Art. 1, p. 46, pl. 5, figs. 3-4. Description. — Narrowly elongate shells with steady small in- crease in width throughout length of shell; angle formed by dorsal and ventral margin about 15 degrees; hinge line straight and thick- ened on each valve by curled roll of shell material containing liga- ment and projecting above regular cylindrical body of shell; mod- erately inflated; growth lines passing from nearly parallel to dorsal margin to perpendicular to it, past perpendicular, then joining dorsal margin at about a 70 degree angle, inclined towards the anterior; growth lines smoothly curved on postero-ventral margin; shell orna- mented with small, sharp, regular growth lamellae spaced about 1-2 mm apart; radial ornament lacking; beak apparently subterminal; shell wall thin; greatest height about 2 cm, on projected length of 10 cm; other characters unknown. Discussion. — This species is similar to M. americana, in having a small size with low angle of increase in height, and regular external growth lamellae. M. sagitta can be distinguished from M. americana by the angle of the growth lines as they join the hingeline. The angle of approach is approximately 90 degrees in M. americana, and is about 70 degrees in M. sagitta, with the growth line inclined toward the beak. For a discussion and description of M. americana see Meek (1872) and Girty (1915). The specimens found in the Arcturus Group differ somewhat from the holotype collected in the Kaibab Formation in being less elongate. Chronic (1952) described them as having a slightly thick- ened cardinal margin (hingeline), but in the Arcturus specimens this appears to be mostly a folding of the shell wall along the hinge- line to form a groove, presumably to contain the ligament, and the hinge is only slightly thickened. The holotype does not show any evidence of growth lamellae, but this feature appears to be charac- teristic of the group and can be expected on topotype material. M. sagitta is known from the Loray Formation of the Arcturus Group of Leonardian age, from the Kaibab Formation of latest Leonardian or earliest Guadalupian age, and from the Tosi Forma- PERMIAN BrRACHIOPODS AND Mo.iuscs: YANCEY 341 tion and Ervay Formation of the Park City Group of Guadalupian age. The species is found in fine-grained shaly substrates and lived in quiet water areas. Occurrence. — Loray Formation, loc. UCMP D-5606, D-5608, D-5609, D-5612, D-5617, Butte Mountains, Nevada. Genus AVICULOPINNA Meek, 1864 Type species: Avicula pinnaeformis Geinitz, 1848. Description. — Elongate, narrow pinnids with markedly sub- terminal beak; having subdued, non-regularly spaced ornament; thin shell wall. Discussion. — Arcturus pinnids lacking regularly spaced growth lamellae are provisionally placed in this genus, as a catch-all for species that do not fit into better defined genera. Pteronites is inap- plicable to Permian species, and they do not fit into Pinna. Aviculopinna peracuta (Shumard), 1858 ? Pl. 10, figs. 12-13 Aviculopinna sp., Winters, Geol. Soc. America, Mem. 89, p. 52, pl. 7, figs. 1a-b.: Description. — Large pinnid bivalves with rate of expansion of about 15 degrees, having a thin but strong shell wall; long and straight cardinal margin (hingeline), with curved roll of shell ex- tending few mm above main body of shell from each valve, holding ligament; well inflated, forming near circular cross section; shell externally smooth except for growth lines, these sinusoidal, curving from parallel to ventral margin around posterior margin to position about perpendicular to dorsal margin, and curving posteriorly while appoaching hingeline at angle of about 60 degrees, inclined away from the beak. Discussion. — This is a distinctive species with smooth, unorna- mented surface, a strong, thickened hingeline, and a strongly in- flated shell, nearly circular in cross section for diameters of a few cm. Only fragmentary material is available, and details of the hinge and ontogenetic changes in growth lines are not known. It is within the prevailing concept of Pinna peracuta Shumard, 1858, but that is such a poorly described and poorly illustrated species that an exact comparison is not possible. Furthermore, a number of similar pinnid species have been described without definite knowledge of population variation or ontogenetic changes, so definite identification of the 342 BuLLeETIN 303 Arcturus and Bird Spring species is not now possible. Among the un- resolved problems is the nature of Pinna consimilis Walcott, 1884, from the Eureka district. A. peracuta ? is usually found in sediments deposited in mod- erate energy environments, where wave or current action was present intermittently. It occurs in rocks with fine- and medium-grained sand size sediments and is most common in limestones. In most oc- currences it is found in an upright position with the beak projecting downward in the sediment. Under favorable conditions they were common and occurred in clam fields showing life orientation, usually with few other fossils. A. peracuta ? is moderately common in the Arcturus Group and strata of equivalent age in the western states. It is known from the Pequop Formation and Loray Formation of the Arcturus Group, and the Fort Apache Member of the Supai Formation, all of Leonardian age, and from the Bird Spring Formation of Clark County, Nevada, in a horizon believed to be late Wolfcampian in age (Plas, 1972). Occurrence. — Pequop Formation, loc. UCMP D-5540 and Loray Formation, loc. UCMP D-5527, Egan Range, Nevada; Pe- quop Formation, loc. UCMP D-5614, D-5623, Medicine Range, Nevada; Arcturus Formation, loc. UCMP D-5576, Confusion Range, Utah. Aviculopinna sp. Pl. 10, fig. 14 Description. — Small pinnid with moderately rapid posterior expansion of shell; moderate inflation, thin shell wall; and numerous small corrugations of the shell wall perpendicular to the hingeline. Discussion. — This is represented by one specimen but appears to be distinct from other pinnid species. The shell wall is intensely corrugated with small scale folds that do not appear to be due to crushing. The shell is too small and incomplete to make a good com- parison with other species. Occurrence. — Loray Formation, loc. UCMP D-5606, Butte Mountains, Nevada. Order PTERIOIDA Newell, 1965 Suborder PTERIINA Newell, 1965 Superfamily AMBONYCHIACEA Miller, 1877 PERMIAN Bracuiopops AND Mo.tiuscs: YANCEY 343 Family MYALINIDAE Frech, 1891 Diagnosis. — Heavy shelled ambonychiids normally with strongly produced beak; slightly inequivalved; edentulous or with cardinal tooth beneath beak on right valve and furrow on left valve; pallial line entire. Discussion. — These massive shells are among the best known of upper Paleozoic bivalves. The genera Myalina and Eurydesma are widely distributed, typical examples of the family. The hinge area is often broadened with many ligamental grooves. Genus MYALINA de Koninck, 1842 Myalina de Koninck, 1842, Description des animaux fossiles qui se trouvant dans le terrain carbonifere de Belgique, p. 125. Mryalina de Koninck, Newell, 1942, Geol. Surv. Kansas, vol. 10, part 2, pp. 45-46. Type species: Myalina goldfussiana de Koninck, 1842. Diagnosis. — Heavy thick shells with terminal beaks and heavy hinge area containing few to numerous ligamental grooves running oblique to the hingeline, having tendency toward quadrate shape. Discussion. — This genus has been extensively monographed by Newell (1942), who gave full descriptions of the genera in the family Myalinidae. Myalina sp. Pl. 10> fig. i Discussion. — Juveniles of an undetermined species of Myalina s.l. are present in the Arcturus Group. They are all small and where adequately preserved show regular lamellar ornament. This type of ornament is present in several subgenera of Myalina but is most characteristic of Septimyalina. However, present material is inade- quate to determine if the Arcturus specimens should definitely be placed in that subgeneric group, or if they can be identified with any of the species described by Newell (1942). A similar form was described by Walcott (1884), as M. congeneris Walcott for material from eastern Nevada, but the horizon of its occurrence is not certain and not enough features are known to permit identification to Newell’s taxa, although it is probably a Myalina (Septimyalina). Therefore, the material bearing this name must be further studied, and compared with midcontinent material before the name can be used. Occurrence. — Riepetown Formation, loc. UCMP D-5637, Maverick Springs Range; Pequop Formation, loc. UCMP D-5626, 344 BuLuetin 303 Medicine Range; Loray Formation, Egan Range, Nevada. Genus SELENIMYALINA Newell, 1942 Selenimyalina Newell, 1942, Geol. Surv. Kansas, vol. 10, part 2, p. 63, fig. 19. Type species: Myalina meliniformis Meek & Worthen, 1866. Diagnosis. — Smoothly rounded shells of ovoid to subquadrate shape, not developing an ear; thin shell; with light hinge containing simple tooth and socket; ligament attachment area slightly curved and not much thickened; beak terminal. Discussion. — This genus is different from Myalina in its ovoid shape and lighter hinge and shell. In its shape it resembles modern Mytilus, but the ligamental features are different, and it is placed in the Myalinidae rather than the Mytilidae. Selenimyalina sp. Pl. 10, figs. 16-17 Discussion. — Abundant small individuals, probably mostly juveniles, of an undetermined species of this genus are present at one locality. They are ovate as juveniles and the margins are not curved, but with further growth the ligamental and anterior margins become curved. These individuals are similar in outline to Pro- mytilus retusus Chronic, 1952 but are clearly not in the genus Promytilus. Because P. retusus Chronic is described only from in- ternal molds, the generic assignment of that species is open to question, so the Arcturus specimens might be conspecific. This species occurs with a restricted molluscan fauna that in- cludes many chiton plates. It is probable that it lived epiphytically along with the chitons, on organisms that grew above the substrate, such as seaweed. Occurrence. —Pequop Formation, loc. UCMP D-5536, Egan Range, Nevada. ? Selenimyalina sp. Plt 10; fig, 18 Description. — Small, elongate myalinids, with high inflation and produced beaks; other features unknown. Discussion. — Poorly preserved specimens from one locality in the Arcturus Group can only questionably be assigned to this genus. They are a little more than 1/2 cm in length, half the size of the smallest described myalinids, and are highly inflated. The beaks are protruding and terminal, and in some individuals are widely spaced. The character of the beaks suggests a relationship to Liebea (Newell, PERMIAN BracHiopops AND Mo.Luiuscs: YANCEY 345 1939), but ligamental grooves are not apparent, and the specimens are too poorly preserved to be identified specifically.

MIDDLE ORDOVICIAN CRINOIDS FROM THE TWIN CITIES AREA OF MINNESOTA By James C. BRowER AND JULIA VEINUS ABSTRACT Two major crinoid faunas are known from the Middle Ordovician of the Twin Cities in Minnesota. The lower fauna occurs in the Hidden Falls Mem- ber of the Platteville Limestone which represents a quiet water habitat. The fauna, including Cremacrinus arctus Sardeson, Cupulocrinus gracilis (Hall), an unidentified camerate crinoid, and lichenocrinid holdfasts, is characterized by strong dominance and low diversity. Cremacrinus arctus was a calceocrinid with reduced hinge mobility, and arms that spread horizontally near the sub- strate to form a collecting bowl. Both features are considered adaptations to a rheophobic habit. Several specimens of Cufulocrinus jewetti (E. Billings) have been found in the Carimona Member of the Platteville Limestone. The depositional en- vironment of these beds was similar to that of the overlying Decorah Forma- tion. The most diversified and equitable crinoid assemblages occur in the Decorah Shale, which has yielded fourteen species with six types of holdfasts. Unlike their Hidden Falls counterparts, the water conditions in the Decorah depositional environments were alternately agitated and quiet, although the former probably predominated. Current agitation produced a shifting and un- stable substrate. The species present are Archaeocrinus sp., Glyptocrinus tri- dactylus, n. sp., Pycnocrinus sardesoni, n. sp., P. multibrachialis, n. sp., Peri- glyptocrinus spinuliferus, n. sp., Cupulocrinus jewetti (E. Billings), C. canali- culatus, n. sp., Grenprisia billingsi (Springer), Carabocrinus dicyclicus (Sarde- son), C. magnificus Sardeson, Palaeocrinus angulatus (E. Billings), Porocrinus pentagonius Meek and Worthen, IJsotomocrinus tenuis (E. Billings), and Cremacrinus punctatus Ulrich. Based on abnormalities of anal plate structure in living and fossil crinoids and on statistical considerations, the holotype of Strophocrinus dicyclicus Sardeson is shown to be an abnormal Carabocrinus with extra plates. Accordingly, Strophocrinus is suppressed and becomes a synonym of Carabocrinus. Thus, Strophocrinus dicyclicus Sardeson is properly termed Carabocrinus dicyclicus (Sardeson). Statistics also denote that C. conoideus Sardeson is a synonym of C. dicyclicus (Sardeson). Six types of holdfasts are present, the most common of which are attached to solid objects like ramose bryozoans. The form genus Podolithus that Sardeson erected for primitive discoid holdfasts is suppressed on morphological and nomenclatural grounds. Carabocrinus dicyclicus was adapted to a low-level niche. The disk-shaped holdfast was cemented directly to the sea floor, and a short, narrow and flexible stem was present. Carabocrinids have an extremely low food gathering capacity (i.e., ratios of number of food-catching tube-feet to tissue volume, and length of food gathering system to tissue volume) because they have a large thin- plated cup in conjunction with non-pinnulate arms. Clearly the arms could not have formed a full mucus-net for trapping small food particles as in most pin- nulate crinoids (e.g., living comatulids). Probably carabocrinids caught large food particles directly with the tube feet. Relative to most low-level crinoids, C. dicyclicus (Sardeson) exhibited a low bulk density that suggests it was not fully adapted to this mode of life. Several cupulocrinids had long narrow stems which were attached to ramose bryozoans by small lobate or digitate holdfasts. This may also have been true for Grenprisia springeri and perhaps some other crinoids. Crema- crinus punctatus, in contrast to C. arctus of the Platteville, exploited the normal calceocrinid mode of life with a recumbent stem and fully functional hinge. Study of variation in arm branching patterns in cupulocrinids and crema- crinids from the Twin Cities shows that the number of plates in proximal series of brachials is less variable than in more distal parts of the arms. Wider 374 BuL_eTin 304 brachial series exhibit more branches than narrower ones. The presence of spear-shaped axillaries allows the development of more arm branches than if the axillaries had parallel lateral margins. Indices developed from network theory are useful in the characterization of arm branching patterns. INTRODUCTION Over a period of about fifty years ranging from 1892 to 1940, I’, W. Sardeson produced almost one hundred papers dealing with the geology of the Twin Cities area. About sixty percent of these dealt with Ordovician stratigraphy and paleontology (see Melone and Weis, 1951, pp. 52-56, for a complete bibliography of Sardeson). During this interval, Sardeson collected numerous crinoid specimens, including about fifty crowns and dorsal cups, several thousand iso- lated plates, and numerous stem and attachment devices, from the Platteville Limestone and the Decorah Shale of the Twin Cities area. Despite this mass of material, only a few papers were written about the Ordovician crinoids of the Twin Cities area. In 1897, Ulrich (in Winchell and Ulrich, p. cxii) listed crinoid species present in the Platteville, Decorah and Galena Formations of the Twin Cities. These names were published without description or illustration; some were new and represent nomina nuda. Although we have examined both the collections of the National Museum of Natural History and the University of Minnesota, where the Sarde- son collection is housed, we were not able to find any of Ulrich’s labels.

The carabocrinids were described in 1899, 1908, 1925, and 1939. Although Sardeson’s taxonomy is now partially obsolete, his work was innovative. He speculated on the evolution of carabocrinids at a time (1899) when most writers were con- cerned with descriptive taxonomy. Sardeson believed, incorrectly, that carabocrinids formed a link between cystoids and crinoids. It is now known that crinoids (carabocrinids are bonafide crinoids) and cystoids are not closely related (Ubaghs, 1967). In 1939, Sardeson reconstructed dorsal cups of carabocrinids from isolated plates. This was, to the best of our knowledge, the first published reconstruction of a Paleozoic crinoid. In 1928, Sarde- son described calceocrinids from the Twin Cities area, and gave a detailed analysis of the living habits and paleoecology of Crema- crinus arctus and C. punctatus. In the 1928 paper, when discussing the phylogeny of the calceocrinids, Sardeson also outlined a mecha- nism for the transition from dicyclic to monocyclic crinoids. This theory has been largely ignored, and has never been adequately tested. In 1908, Sardeson proposed a novel form of classification for crinoid holdfasts. Primitive discoidal roots were placed in the “genus” Podolithus. “Species” were named according to the genus to which the holdfast belonged. For example, the holdfast of Dendro- crinus was termed Podolithus dendrocrinus. Although ingenious, this classification has not been adopted by subsequent authors. One problem is that the Sardeson nomenclature is not acceptable under the current rules of The International Commission on Zoological Nomenclature. In the Twin Cities area, holdfasts and complete stems have not been seen attached to dorsal cups or crowns. In our opinion, the main significance of Sardeson’s 1908 paper is that he clearly realized the importance of detailed studies of crinoid hold- fasts, and that he attempted to match holdfasts with crowns based on frequency of association and morphological criteria. Several other authors have briefly described Twin Cities crinoids. Ulrich (1886) proposed Cremacrinus punctatus, while Fenton (1929a,b) illustrated a cincinnaticrinid and numerous lichenocrinid holdfasts from Minneapolis and St. Paul. 376 BuLueTin 304 ACKNOWLEDGMENTS We thank the following institutions and individuals for the loan of specimens: University of Minnesota, Sardeson Collection and other materials (UM), R.

Sloan originally suggested that we undertake this study and furnished information on the stratigraphic occur- rence of many of the crinoids. Lance Grande, a graduate student in paleontology at the University of Minnesota, provided localities for many of the crinoids. Lance Grande and R. E. Sloan guided one of us (J. C. B.) to several collecting sites. Prof. G. Ubaghs of the Uni- versity of Liege in Belgium kindly provided copies of the generic diagnoses of glyptocrinids to be published in the Treatise on Inverte- brate Paleontology. John M. Warn of the University of Cincinnati identified the specimen of Jsotomocrinus tenuis (FE. Billings). R. V. Harris, formerly of Syracuse University, measured the carabocrinid plates and performed some preliminary statistical analyses on the data. The cost of engraving the illustrations has been defrayed by Syracuse University.

COMPOSITION OF CRINOID FAUNAS IN THE TWIN CITIES AREA Most of the crinoids for this study are either from the Sardeson collection at the University of Minnesota, or from material collected by E. O. Ulrich and his associates at the National Museum of Natural History. Sardeson and Ulrich did not provide detailed localities for most of their specimens. Most locality labels simply give the stratigraphic horizon, and either “Minneapolis” or “St. MIppLE OrpDovVICIAN CRINOIDS: BROWER & VEINUS 377 Paul”, although precise labels accompany some specimens. Sarde- son, however, did combine specimens found at a single collecting site. Mr. Lance Grande, a paleontology graduate student at the University of Minnesota who has collected fossils in the Twin Cities area for many years, examined many of the crinoids and provided precise geographic localities for many of them. Many of the roots and holdfasts were collected by Mr. D. Wallace, curator emeritus of the Geology Department at the University of Minnesota. Over the years, geology students and faculty of the University of Minnesota have added specimens to the collections. Some of the lichenocrinids described by Fenton (1929a) are located in the Geology Museum at the University of Cincinnati. For this study, we have examined about one hundred crowns and dorsal cups, several hundred holdfasts, several thousand isolated plates, and an uncounted number of stem segments. Sardeson used “Beds 1 to 6” as stratigraphic horizons for crinoid-bearing strata in the Twin Cities area. These fit into the current formal stratigraphy given with the following faunal lists (R. E. Sloan, personal communication). Reviews of the Ordovician stratigraphy and paleoecology of the Twin Cities area may be found in Stauffer and Thiel (1941), Agnew (1956), Weiss and Bell (1956), Austin (1972), and Webers (1972). PLATTEVILLE LimMEsTONE, H1ppEN Farts MEMBER (Beds 1 and 2 of Sardeson) Cremacrinus arctus Sardeson Cupulocrinus gracilis (Hall) Unknown camerate crinoid Lichenocrinid holdfasts The table above indicates that the Hidden Falls crinoid fauna is characterized by low diversity. The fauna is dominated by Crema- crinus arctus and the lichenocrinid holdfasts that account for over 95 percent of all specimens known. Both Cupulocrinus gracilis and Cremacrinus arctus are present in the Platteville Formation of Wis- consin and Illinois. The former species is also found in the Trenton Group of New York. Thus the Hidden Falls fauna is most similar to the Platteville assemblages of adjacent areas in Wisconsin and Illinois. 378 BuLuetin 304 PLATTEVILLE LIMESTONE, CARIMONA MEMBER Cupulocrinus jewetti (E.

Miupbte Orpovician Crinoips: BROWER & VEINUS 379 Of the five previously described species that occur in the Twin Cities area, Cupulocrinus jewettr (E. Billings), Grenprisia billingsi (Springer), Palaeocrinus angulatus (E. Billings), Porocrinus penta- gonius (Meek and Worthen), and Jsotomocrinus tenuis (E. Bil- lings), four are shared with the Ottawa Limestone of Ontario and Quebec, two with the Curdsville Limestone of Kentucky, two with the Galena Dolomite of Illinois, and one with the Platteville Lime- stone of Illinois. Three other species, Carabocrinus dicyclicus (Sar- deson), C. magnificus Sardeson, and Cremacrinus punctatus Ul- rich, are mainly confined to the Twin Cities area and adjacent parts of Wisconsin. However, the closest relatives of these forms are from the Ottawa Limestone of Canada (three species), and the Curdsville Limestone of Kentucky (two species). For the five new species in the Twin Cities, Glyptocrinus tridactylus, n. sp., Pycno- crinus sardesont, n. sp., P. multibrachialis, n. sp., Periglyptocrinus spinuliferus, n. sp., and Cupulocrinus canaliculatus, n. sp., the most similar crinoids are from the Ottawa Limestone of Canada (five species), the Curdsville Limestone of Kentucky (one species), the Galena Formation of Illinois (one species), and the Platteville Lime- stone of Illinois (one species). Thus the Decorah Shale crinoids from the Twin Cities are most closely linked to Canadian assem- blages, and have less affinity with the faunas of neighboring areas in the United States. PALEOECOLOGY INTRODUCTION The Twin Cities area provides a unique opportunity to study two contrasting crinoid faunas, an older low diversity assemblage from a quiet water environment, and a stratigraphically younger suite of crinoids which lived in a more agitated environment. For previous discussion of the paleoecology of the crinoid habitats, see Sardeson (1899, 1908, 1926, 1928). FAUNA OF THE HippEN Farts MEMBER OF THE PLATTEVILLE LIMESTONE The crinoids and associated organisms were probably collected from a single bedding plane in the Johnson Street Quarry in Min- neapolis. The crinoids are dominated by Cremacrinus arctus with 380 BuLLeETIN 304 fewer lichenocrinid holdfasts, and specimens of Cupulocrinus gra- cilis. The crinoids are associated with the starfish Protopalaeaster narrawayt Hudson, edrioasteroids, cystoids, articulate brachiopods such as Dinorthis deflecta (Conrad) and Rafinesquina minnesotensis (Winchell), graptolites, bryozoans, and some molluscs. The en- closing rock is soft, yellow to buff, fine-grained dolomitic limestone. Specimens are commonly preserved in living position. Some orthid brachiopods are found with the interarea pressed down on the seabed to which they were probably attached by a short pedicle (Sardeson, 1929). Cremacrinus arctus lived with the dorsal cup partially buried in the sediment. The arms were spread horizontally to form a bowl for collecting a vertical rain of either or both plankton and organic detritus (Sardeson, 1928; see Text-figure 8, and discussion of C. arctus herein). The starfish were partially buried in the sediment with the disk exposed, the food grooves down, and the tips of the arms under the substrate. This probably represents the original living position (see illustrations in Kesling, 1962). Predominantly quiet water conditions in the habitat occupied by the crinoids are indicated by the fine-grained sedimentary rocks and by the preservation of brachiopods, crinoids, and starfish in their original living positions. This is also consistent with the col- lecting-bowl food-net of Cremacrinus arctus which probably evolved to catch a vertical rain of food particles. Some current activity was necessary to assure the predominant filter feeding organisms an adequate food supply and to remove waste products. Sedimentation rates were probably slow when the animals were alive. The preserva- tion of many complete crinoid crowns, and brachiopods and starfish in living position also suggests rapid to catastrophic burial. Thus the Platteville assemblage in the Johnson Street Quarry is interpreted as a consensus assemblage where preserved specimens include both individuals that were buried alive as well as shells and disarticulated skeletons of organisms which had died earlier. Normal marine conditions are denoted by the crinoids as well as the diverse articulate brachiopods. DecorAau SHALE CRINOIDS The crinoids, cystoids, and some other echinoderms occur in a bioclastic limestone or calcareous shale. The fossil material mainly MippieE OrpoviciAN CRrINOIDS: BROWER & VEINUS 381 consists of echinoderm debris, broken bryozoans, and brachiopod shells. The bryozoans include ramose and sheetlike forms that were probably erect and rigid during life. Some encrusting species and rare hemispherical colonies were also found. The detrital constitu- ents of the rock vary from sand-sized calcite, mostly of organic origin, to clay-sized material. The bedding surfaces are almost always irregular. This indicates a rough and hummocky substrate during life of the fauna. Commonly, the ramose bryozoans are aligned. The water was probably strongly agitated at times. This is denoted by the aligned bryozoans, the bryozoan colony types present, the nature of crinoid burial, and the chaotic texture of the sediment. Sardeson (1928, p. 46) reached similar conclusions. He visualized the habitat as just offshore in the zone of tidal currents, alluding to features such as ridged-up long windrows of shell rock. Certainly, the substrate was uncohesive, and fossil debris and sedi- ment particles were actively transported during agitated intervals. The fine-grained sediment was deposited during quieter water con- ditions. Thus the habitat was variable with respect to wave and current agitation. Most of the crinoids are represented by isoiated plates and stem segments, and complete dorsal cups and crowns are comparatively rare. With rapid burial, the crinoid would be covered with sediment before much disintegration and breakage took place (e.g., Brower, 1973, pp. 269-271). The main breakage would have been associated with collapse of the dying animal onto the seabed. The burial pro- cess could be augmented by the pressing of the crinoid down into the sediment. Relatively complete specimens would be preserved under rapid burial conditions. With slow burial, disintegration and breakage, due to scavengers and decomposition, would be com- pleted. The result would be isolated calyx, arm, and column plates. With intermediate burial rates one would expect to find calyces or dorsal cups, perhaps with arm and stem segments, isolated colum- nals, and brachials. It should be realized that the absolute sedimen- tation rate would vary depending on the environment. With high agitation as in the Decorah habitats, the time required for burial would be shorter than in a quiet water area. Slow crinoid burial rates may imply that the agitated intervals predominated. Normal marine salinity is indicated by the groups present and 382 BuLuetin 304 by their diversity. Associated with the crinoids in the Decorah beds are numerous bryozoans, brachiopods and some cystoids. Approxi- mately fourteen crinoid species are known, along with six types of holdfasts. Living crinoids are restricted to normal marine salinity. Almost the entire fauna consists of epifaunal filter feeders. The frequent agitation would have assured these forms an adequate and continuous supply of dissolved oxygen and food. The currents also served to transport sperm from male to female crinoids and to remove waste products such as carbon dioxide and fecal material. The uncohesive substrate presented the crinoids with attach- ment problems. Most of the Twin Cities crinoid root forms fall into the following categories. 1) Small lobate or digitate holdfasts usually cemented to ramose bryozoans and, rarely, to crinoid stems (PI. 25, figs. 1-5). In most cases, these roots only occur on one side of the bryozoan. This sug- gests that they became attached after the dead bryozoan colony was broken up and the pieces scattered about on the seafloor. In a few instances, the roots are found on all sides of the bryozoan, and the crinoids may have fixed their disks to a live bryozoan. The small size of the attachment devices suggests small adult or immature crinoids. 2) Lichenocrinid holdfasts are most often observed attached to strophomenid brachiopods. Many are located on the interior of one of the valves, and obviously the larvae settled on a dead shell. Others were seen on the exterior of articulated valves; perhaps these were present when the strophomenid was alive. Some specimens are also found on broken fragments of ramose bryozoans. 3) The large disk-shaped holdfasts of Carabocrinus (Pl. 23) have been seen cemented directly to the substrate, to corrosion sur- faces or hardgrounds, and to ramose bryozoans. 4) A similar massive conical attachment-disk was attached to a receptaculitid pebble on the seabed (PI. 25, fig. 7). 5) Stem segment with cirri wrapped around a bryozoan (PI. 24, fig. 19). 6) Large tree-stump-like cirrus roots may belong to adult glyptocrinids (Pl. 25, fig. 6). These are similar to the Barycrinus roots shown by Wachsmuth and Springer (1897, p. 46, pl. 1, figs. 4 and 5). Miupp_e OrpoviIciAN CRINOIDS: BROWER & VEINUS 383 Of the above root types, the first three are common, whereas the last three are comparatively rare. Of the common types, only one of the three was ever attached to uncohesive substrate; the others were joined to solid objects. The carabocrinids solved the problem of un- cohesive substrates by cementing the root to an area that was large compared to the size of the crinoid. The only other soft substrate attachment device, Type 6, probably fixed itself within the shifting sediment by deep root penetration. The distribution of the sub- strate-attached versus other root types was probably related to sub- strate stability. For general discussions on crinoid roots, see Ehren- berg (1929) and Brower (1973, pp. 281-283). Isolated columnals recovered alone or in association with either or both roots and calyces are of several different types (PI. 24, figs. 9-14), but cannot confidently be identified with any of the crinoid species reported here. SUMMARY Generally the Platteville crinoid assemblages are characterized by low diversity and the strong dominance of Cremacrinus arctus and the lichenocrinid holdfasts. This dominance-diversity relation- ship suggests the Platteville was a marginal and perhaps stressed environment for crinoids. Quiet water was the most probable limit- ing factor. In contrast, the overlying Decorah contains a much more diverse and equitable fauna. Strongly agitated conditions alternated with the intervals of quiet water during which fine-grained sediments were deposited. On an unstable and shifting substrate, bryozoans pro- vided suitable attachment surfaces for Twin Cities crinoids with lobate, digitate and other types of holdfasts. The disk-shaped roots of carabocrinids were cemented to hardgrounds, pebbles on the sub- strate, bryozoan colonies, and directly to fossil debris on the sea- floor. Several root types were cemented to or rooted within the sub- strate. This agitated habitat provided a more favorable environment for crinoid species than did the underlying Platteville. STATISTICAL STUDIES OF TWIN CITIES CARABOCRINIDS INTRODUCTION Carabocrinids are by far the most abundant crinoids in the 384 BuLwetin 304 Twin Cities area; over 1000 plates of these animals were available for study. The nomenclature of these carabocrinids is complex and confused, mainly because most of the material is preserved as dis- articulated plates. Accordingly statistics were used to aid in estab- lishing a correct taxonomy. Previous Work Sardeson (1899, p. 264, pl. 12, figs. 1-17, text-figs. 1, 2) pro- posed Strophocrinus based on S. dicyclicus, the type and only known species, from the Decorah Shale of St. Paul. The form was based on a partial, flattened dorsal cup with the distal parts of some radials broken off (see Pl. 20, figs. 10, 12, 13; Text-fig. 1). Although not so stated, this crinoid was obviously considered the holotype. Sarde- son also studied isolated plates and holdfasts which he believed were conspecific with S. dicyclicus. He clearly separated Strophocrinus from Carabocrinus and allied crinoids. Sardeson published three dif- ferent plate diagrams of the holotype of Strophocrinus dicyclicus at various times (1899, text-figs. 1, 2; 1925, pl. 5, figs. 1, 3; 1939, pl. 2, fig. 3). The 1899 figures depict 21 plates but only 20 appear in the later drawings. No explanation is given for this discrepancy. We con- sider the later figures to be correct, and the 20-plate version is repro- duced in Text-figure 1. The holotype has 20 plates in the dorsal cup: five infrabasals, five basals, five radials, one inferradial, two super- radials, and two plates in the anal X position. The radial facets are narrow and horseshoe-shaped. Several unbranched primibrachs occur in one ray. Typical calyx plates are highly ornamented with many round and slightly elongate nodes. In some specimens the nodes are either or both aligned into stellate ridge type patterns and in rows paralleling the plate margins. Commonly the nodes exhibit no con- sistent pattern. According to Sardeson (1899, p. 270; 1925, p. 60; 1939, p. 29), Strophocrinus differed from Carabocrinus (E. Billings, 1857, p. 275) in having more anal plates; the extra superradial and supple- mental anal X of Strophocrinus are not known in normal carabo- crinids (Text-fig. 1). The two crinoids are otherwise identical. This led some authors to treat Strophocrinus as a synonym of Carabo- crinus (e.g., Bassler, 1915, p. 182; Foerste, 1924, p. 349). Although these authors did not discuss their reasoning, Strophocrinus dicych- cus was probably considered as an abnormal Carabocrinus.

Sardeson (1925, 1939) continued to maintain S. dicyclicus either as the type species of Strophocrinus or as a species of Carabocrinus. Sardeson’s (1925) discussion of the problem of differing numbers of anal plates between species was partly stimulated by the comments of Bassler (1915, 386 BuLueETIN 304 p- 182) and Foerste (1924, p. 349). This was the main basis for separating Carabocrinus from Strophocrinus. Sardeson (1925, pp. 63, 64) cited the views of Bather and Springer that . these azygous (anal) plates were introduced to the dorsal cup from the tegmen, or ventral top of the body. Because of his colleagues’ dubious acceptance of S. dicyclicus, Sardeson briefly entertained the idea that the crinoid was a sport (abnormal form) of Carabocrinus. Sardeson (1925, p. 64) immedi- ately dismissed this thought, along with his friends, with the com- ment In reviewing my fossil collections and the evidence as a whole in this case, I have even tried to find that my type specimen was a sport merely of some good species of Carabocrinus. The evidence found is yet still to the contrary, so that I am constrained to treat the evidence and my friends with equal favor. Sardeson (1939, p. 30), in response to Bassler’s (1915, pp. 182, 1225) and Foreste’s (1924, p. 349) citations of Strophocrinus dicych- cus as Carabocrinus dicyclicus, stated that Strophocrinus dicychcus could be a pathologic or abnormal individual of Carabocrinus. Sar- deson’s only concession at this point was to say that if Stropho- crinus dicyclicus is a Carabocrinus, then it is a species yet to be described. Later in the same paper, Sardeson wrote (1939, pp. 30, 32) After the proposed Strophocrinus dicyclicus Sardeson appeared to have been recognized authoritatively, the species was again found in a list of fossils, not as Strophocrinus, but as Carabocrinus dicyclicus (Sardeson), by R. S. Bassler, in Bulletin of the U.S. National Museum, No. 92, page 182, and page 1225 (1915). Again it appeared as Carabocrinus dicyclicus Sardeson as given by Dr. August Foerste, in Iowa Geological Survey, Volume XXIX page 349 (1924). Explanation for such mental confusion appeared not to be that those authors extend the definition for the genus Carabocrinus to include my type- specimen of Strophocrinus. In fact no explanation appeared. Rather possibly the National Museum has a different form labeled under that name. Carabocrinus dicyclicus Sardeson (1925, p. 61, pl. 5, fig. 5) was based on isolated plates collected from the Decorah Formation of St. Paul and Kenyon, Minnesota, and Ellsworth, Wisconsin (see Pl. 20, fig. 11 for “holotype” plates; Sardeson reillustrated these plates in 1939 [pl. 2, fig. 5] ). As of 1925, complete cups and crowns were unknown, although several poorly preserved examples were collected subsequently. Sardeson (1925, p. 61) contrasted C. dicych- cus and Strophocrinus dicyclicus as follows: 1. The carabocrinid dorsal cup is probably ovoid rather than hemispherical as in Strophocrinus. ‘ 2. Smaller mature plates occur in Carabocrinus dicyclicus. MIppLE OrpDoVICIAN CRINOIDS: BROWER & VEINUS 387 3. The carabocrinid plates bear sharper ridges and fewer nodes. 4. Strophocrinus exhibits more anal plates with different shapes. By 1939, Sardeson had constructed dorsal cups of Carabocrinus from isolated plates, using the following procedure (pp. 33, 34). The plate circlets were selected from loose material to correspond to the structure of Carabocrinus. Wet clay balls of almost the right size were made. Plates were superimposed on the clay lumps, and the clay balls molded until the plates fitted together. The clay balls were then cast in plaster and the plates were permanently stuck on. Four cups from St. Paul and one cup from Ellsworth, Wisconsin were so restored (Sardeson, 1939, pl. 2, fig. 6; see Pl. 19, figs. 3, 5, 6; PI. 21, fig. 14). Sprinkle (1973) used the same method for Ordovi- cian hybocrinids. C. conoideus Sardeson (1925, p. 62, pl. 5, fig. 4; see Sardeson, 1939, pl. 2, fig. 4; Pl. 20, fig. 9) was based on a small dorsal cup about 18 mm high from the Decorah of St. Paul. The predominant plate ornamentation consists of fine ridges. Sardeson considered that the crinoid was easily separated from Strophocrinus dicyclicus and Carabocrinus dicyclicus by differences in cup shape and ornamenta- tion. Sardeson )(1939,-pp: 33, 34, pl. 2, fig. 6; Pl. 19; figs. 3,5, 6; PL 21, fig. 14) restored dorsal cups of C. dicyclicus and realized that C. conotdeus was an immature C. dicyclicus (1939, pp. 36, 38). Ac- cordingly C. conoideus was placed in the synonymy of C. dicyclicus. C. magnificus first appeared in Winchell and Ulrich (1897, p. 123) without description. The name was simply a nomen nudum and was free to be used later. Sardeson formally described C. magni- ficus in 1939 (p. 33) based on approximately 400 loose plates. Several dorsal cups were built using the method mentioned for C. dicyclicus (Sardeson, 1939, pp. 33, 34, pl. 2, figs. 1, 2; Pl. 19, figs. 1, 2, 4). Specimens are rare at Ellsworth, Wisconsin, fairly common at St. Paul, Minnesota and ubiquitous in the Decorah Shale at Can- non Falls, Minnesota. Sardeson (1939, p. 34) cited ornamentation as the main difference between C. magnitficus and C. dicyclicus. C. magmificus has fewer, and more continuous stellate ridges in con- trast to the more numerous pimple-studded ridges of C. dicyclicus. Also according to Sardeson, the posterior basal is larger than the right posterior basal in C. dicyclicus; the reverse is true in C. magni- 388 BuLuetin 304 ficus. In Strophocrinus dicyclicus, these plates are about the same size, but are compensated for by extra anal plates. As discussed in the subsequent text, the plate and dorsal cup shapes of the two carabocrinids are easily distinguished. Sardeson (1939, p. 34) also recognized developmental changes in C. magnificus. Young plates are thin and smooth, but single stellate ridges are soon acquired. The stellate ridges become rounded with increasing age, and new stellate ridges form parallel to the older ones. These growth trends cannot be fully confirmed. Since Sardeson’s work in 1939, the thin and young plates have been lost from the University of Minnesota paleontological collections. However, larger plates do tend to add stellate ridges during ontogeny (PI. 22). Sardeson (1899, pp. 268, 269, pl. 12, figs. 15-17; Pl. 23) noted holdfasts that were associated with Strophocrinus dicyclicus. He clearly grouped the attachment devices with the crinoids. The disk- shaped holdfasts exhibit pentameral symmetry. Sardeson believed this holdfast to have one, two, or possibly three layers of plates. Material in his collection shows two distinct layers. The basal layer, cemented to the substrate, bears a series of radiating ridges that show a more or less well-developed four- or five-fold symmetry (PI. 23, figs. 1-3, 5, 6). Some of these ridges are hollow and it is possible that these were derived from cirri, as suggested by Sardeson. Sarde- son thought the basal layer was multi-plated. Although several specimens exhibit ill-defined plate sutures (PI. 23, fig. 2), no traces of plate sutures can be found in most (PI. 23, figs. 1, 3, 5, 6). Clearly the lower layer was functionally a single solid plate. The overlying smooth layer is made up of a series of regular plates; the plate su- tures are obscure but can be seen under water or alcohol. A small round or obscurely pentagonal stem scar is visible. In 1908 (p. 242) Sardeson coined the form genus Podolithus for various crinoid holdfasts with the following diagnosis: Primitive discoid or conical Crinoidal root structures with more or less lobate margins and with a fixing-plate. Region about the stem-scar not depressed. These holdfasts have created other sources of confusion. For example Westphal (1974, p. 79, pl. 1, figs. 1, 2, text-fig. 1) described a lower layer of one of these holdfasts as Disconia pentamerus, in- terpreting the specimen as a discoidal anthozoan coral with penta- meral symmetry. This confusion is not unreasonable because West- Mippie OrpoviciAN CrINoIDS: BROWER & VEINUS 389 phal had not seen complete holdfasts that were associated with crinoids. By itself, the lower layer of one of these holdfasts bears little resemblance to an attachment device of a pelmatozoan and the specimen could easily be placed in another phylum. Various “species” of Podolithus were described and named; the specific names consisted of the genus to which the holdfast was as- signed. For example, Strophocrinus dicyclicus roots were named Podolithus strophocrinus. Also proposed were P. schizocrinus, P. anomalocrinus, P. eucheirocrinus and P. dendrocrinus (Sardeson, 1908, pp. 242-248; see later discussion of crinoid attachment de- vices). Subsequent authors have not followed this form genus con- cept, and the Sardeson classification is not acceptable under the current rules of the International Commission on Zoological Nomen- clature. Typically P. strophocrinus is listed as a synonym of Stropho- crinus dicychicus ( e.g., Bassler, 1915, p. 182; Foerste, 1924, p. 349; Bassler and Moodey, 1943, p. 690). Biologically, this is appropriate. Whenever possible, a holdfast should be placed with the crinoid that constructed it. Form genera are applicable where the attachment de- vices cannot be assigned to specific crinoids. It is notable that Sarde- son never mentioned Podolithus after 1908. A similar problem exists for crinoid stems. Russian workers (e.g., Yeltysheva, 1955, 1956, 1959) commonly use form classifica- tions. Usually, the stems cannot be assigned to a single crinoid. Moore and Jeffords (1968) employ a biological system. If possible, the stem is grouped with the appropriate crinoid species, e.g., Jo- crinus subcrassus (Meek and Worthen) (Moore and Jeffords, 1968, p. 32, pl. 1, fig. 3). Some new species based on the column (e.g., Gilbertsocrinus vetulus), were placed in well-established genera (Moore and Jeffords, 1968, p. 38, pl. 3, fig. 1). Some new taxa [like Hyperexochus Moore and Jeffords (1968, p. 33)] are based only on stems. It seems likely that taxa based upon columns will present nomenclatural problems in the future. As of 1939, Sardeson’s views were as follows. Although suspect, Strophocrinus dicyclicus was a valid species. Two species of Carabo- crinus, C. dicyclicus and C. magnificus were retained. C’. conoideus was thought to be conspecific with C. dicyclicus. Podolithus stropho- crinus was placed in synonymy with Strophocrinus dicyclicus. Sarde- son (1899, 1925, ?1939) considered Strophocrinus as a surviving 390 BuLueTin 304 species of a transitional form between rhombiferan cystoids and true crinoids such as Carabocrinus and other dicyclic inadunates (see 1899, p. 273). STATISTICAL TECHNIQUES Two methods were used for sample comparison. In one instance, a one-way analysis of variance with one variable served to treat the data (see Sokal and Rohlf, 1969, pp. 175-252 for outline of the technique); computations were done with the APL program ANOVA2 (documentation available from the University of Al- berta). Most pairs of samples were analyzed by generalized dis- criminant analysis (explanation in Seal, 1964, pp. 123-152). Three types of information have been considered: 1) Probabilities that the groups were drawn from the same statistical population. 2) Coef- ficients that indicate the contribution of each variable to the con- trasts between the groups. 3) Discriminant functions. The discrimi- nant function may be used to identify or classify individuals. Here two types of identification or classification are involved. Consider a specimen originally allocated to Group A. If discriminant function analysis assigns the specimen to Group A, then the classification or identification is correct. An incorrect identification occurs if the dis- criminant function places the individual in Group B. The same rea- soning holds for individuals originally located in other groups. In this study, the specimens were allocated to groups by the discrimi- nant function procedure based on the minimum value of Mahlanobis D? between that particular individual and the centroids of the groups. This ensures that each specimen has equal a priori proba- bility of being assigned to any one group and that each specimen will be placed in the closest group. The correct and incorrect classi- fications by the discriminant functions are summarized in a matrix for all of the groups. The number of discriminant function misclassi- fications relative to the total number of animals is useful because it increases with greater intergroup overlap. This information aids greatly in evaluating the test statistics. The computer program used for the analyses was BMD 07M (Dixon, 1973, pp. 233-253). Statisticians often use the 0.05 probability level to accept or reject the hypothesis that the two groups compared were drawn from the same statistical population. However statistical and bio- logical populations do not necessarily follow the same probabilities. MippLe OrpboviciAN CrRINOIDS: BROWER & VEINUS 391 Paleobiological species should either be defined in terms of their in- ferred reproductive structure or by their distinctiveness in a phyletic chain. The 0.05 statistical probability cannot be related directly to either potential interbreeding or evolutionary position. The approach followed here is to combine test statistics with the number of dis- criminant function misclassifications. These data (tabulated below) suggest that the 0.01 probability level is satisfactory to define the forms studied here. Certainly the 0.05 level results in too many misclassifications to yield meaningful species. Testing of various Paleozoic crinoids shows that 0.01 may be suitable in many instances as it results in an operational taxonomy. This level may also be ap- plicable to other groups. MEASUREMENTS Virtually all of the crinoids are represented by isolated plates. A few poorly preserved cups are available (e.g. types of C. conoideus and Strophocrinus dicyclicus). Also examined were the “model” Carabocrinus dicychcus and C. magnificus constructed by Sardeson. In consequence of the lack of large numbers of cups, only isolated plates were studied quantitatively. The implied reasoning is that if the plates are statistically identical, the dorsal cups must also be identical. The basals are by far most abundant. Radials are moder- ately common but not abundant enough for statistical study of all localities. A few were tested, and yield similar results to those ob- tained from the basals. The infrabasals and anals are too rare for any meaningful statistical treatment. Due to the distribution of material, the statistical treatment focuses on the basals. Three variables were examined: plate height, plate width, and surface ornamentation. Experiments indicated that it was imprac- tical to measure ornamentation elements on a continuous scale. Consequently, ornamentation is grouped into five discontinuous categories (see Pls. 19-22, 24): 1. Plates haying less than 10 stellate ridges, with ridge thickness greater than 1.0 mm. 2. Plates bearing more than 10 stellate ridges, with ridge thickness greater than 1.0 mm. 3. Plates showing numerous fine ridges (commonly more than 15), with ridge thickness less than 0.8 mm. 4. Plates with fine ridges and nodes, discontinuous ridges, or a combination thereof. 5. Plates with only nodes, commonly in a geometric configuration outlining the plate edge. 392 BuLLeTIN 304 Smooth plates are produced by either or both weathering and ero- sion, and were omitted from the statistics. SAMPLES EXAMINED As previously discussed, C. conoideus, C. dicyclicus, and C. magnificus supposedly differ in dorsal cup shape, plate shape, and plate ornamentation. All three crinoids have the same plate struc- ture. The differences, if any, between the three “species” should be fully characterized by measurements of the isolated plates. Stropho- crinus dicyclicus supposedly may be separated from the other “forms” by dorsal cup shape, plate shape, plate ornamentation and number of anal plates. Only the first three differences would be re- flected in isolated plates. The difference in number of anal plates must be treated separately. The following samples of basal plates were measured (number of plates in []). 1. Carabocrinus magnificus Sardeson; Cannon Falls, Minnesota [84]. 2. C. magnificus Sardeson; St. Paul [11]. 3. C. dicyclicus Sardeson; Cannon Falls [5]. 4. C. dicyclicus Sardeson; St. Paul [76]. 5. C. conoideus Sardeson; St. Paul [4]. 6. Stropho- crinus dicyclicus Sardeson; St. Paul [5 plates from the holotype and 3 other plates attributed to this form by Sardeson]. ANALYSES AND RESULTS We have chosen to attack the statistical problem through a series of systematic comparisons of pairs of samples. The results are annotated below and in Table 1. One-way Analysis of Variance Carabocrinus conoideus Sardeson was compared to C. dicyclicus Sardeson, using only the smaller plates with Type 3 ornamentation (see Pl. 21) from St. Paul. Because the basals on the type of C. conotdeus are much smaller than those of C. dicyclicus, it was neces- sary to analyze the height-to-width ratios of the basals. The ANOVA2 program returned an F-ratio of 3.85 with 1 and 11 numerator and denominator degrees of freedom. The probability of a larger F-ratio lies between 0.05 and 0.10 and the null hypothesis is accepted. It is concluded statistically that C. conoideus and C. dicyclicus belong to the same species or population. The sizes of the plates of C. conotdeus suggest that they are from an immature in- 393 MippLe OrpoviciaNn CRINOIDS: BROWER & VEINUS £0? = 069 68° ¢- 80°1 29o'T 00°2 Sie 00+ gel AGG ERERNEN aN L°92 09°! pere3ue ION = 890- v'E2 $s¢'0 969 8h S- $00°0 uryy ssa'y $00°0 ueyl sso'y SO,O)REE Ol'O ueemiag 10°0 pur $200 weemiog 010 uey 419] BaIL) (Isi'z@) gS (O8I‘) £€°8S2 COxe) eESire CSA) aha (ZL°€) 1€S°0 (4[uo yIpim pur 343194) poed 4S pur STE ST uouurs’) “S6—=N uosapseEs SNIVUSVU SNUILIOGDID ) (sajquuea ¢ TTP) pneg "I$ pue sjjey uouury “$6=N uOsapILG SnIfimdvum sSnuUtsI0qQvIN‘) s[[@q uouurg ‘“pg=N uOSapILg snIifimsvm snuts0gvivy Se uouuvy) pure [Neg Ag ‘TS=N uosapi es $NI1] WILD SNU1LIOGDAD) neq 3§ ‘9L=N uosapies snI1IkIip cn ulsI0gvID’) (4[uo yapim puv 343194) STE uouur:) pue yned AS “68—=N (uosapies) sngyaKIip SNU14IOQDID) (saqqenea ¢ [[e) ST[e uouur’) pue phed 4S “68==N (uosapiesg) §I1j9kI21p Snu1s20qQv40-) neq 3S JI=N uOSsspILS SNIUd DU SNU1SIOQDID) td 3S 8=N uosapsieg § nI1jakI1p $NU14I04YF0495 sj[v.j wouues Ni uOSapIPG $nI1jahI1p SNU1LIOGDAD) SUOTBIJIJUAPISIUT UOIWLUSUIL UIC YWPIM jo 93ejusd10q —— SqUaIdIjja0d UOTJIUNZ JURUIWITIOSIC] qWsPH onei-g Josey] jo Arpiqeqoig Jo}PUImIOUSp puv JojyviauInu JO¥J wIOpadlj Jo saaiZdep pue Ojvi-y Z dnoiy J dnoi5 SPIULIOGEID SOIJIQ UIM], IOF suooUNF JULUTUITIOSIG CLA 394 Buttetin 304 dividual of C. dicyclicus, as postulated by Sardeson (1939, pp. 36, 38). Discriminant Function Analyses The height and width provide a measure of the overall size of the plate. The nature of the ornamentation is correlated with the size of the plates in some samples but not in others. The size range of the Strophocrinus dicyclicus basals is less than in Carabocrinus dicychcus and C. magntficus. If all of the data were tested, two sources of contrast would be present: size distribution differences between the two samples, and morphological differences between plates of the same size and relative age. The difference in size distri- bution is due to variables such as collecting bias, differential time-size growth rates, and mortality rates, rather than inherent genetic dif- ferences between the crinoids. To eliminate the differences in size- frequency distribution in comparisons where Strophocrinus dicyclicus is involved, the size ranges of Carabocrinus dicyclicus and C. magni- ficus were adjusted to that of Strophocrinus dicyclicus. In this way only morphological differences between crinoids of comparable size are tested by the discriminant function analyses. Carabocrinus dicyclicus (Sardeson) from St. Paul Vs. Carabocrinus dicyclicus (Sardeson) from Cannon Falls The probability of a larger F-ratio exceeds 0.1 and, presumably the two samples are conspecific. This is consistent with the numerous misclassifications by the discriminant function analysis (29 out of 81 plates were misclassified). Of the Cannon Falls basals, the function misclassified two plates. Of the 76 basals from St. Paul, 27 were mis- identified. It is therefore concluded that the St. Paul and Cannon Falls plates were drawn from the same population. Strophocrinus dicyclicus (Sardeson) vs. all Carabocrinus dicyclicus (Sardeson) As mentioned earlier, the size range of the C. dicyclicus basals was restricted to correspond to that of the smaller S. dicycheus plates. The probability of a larger F-ratio is less than 0.025, but MrppLe OrpoviciAN CRINOIDS: BROWER & VEINUS 395 greater than 0.01, and it is believed that the basals of S. dicyclicus and C. dicyclicus belong to a single population. Of the eight S. dicyclicus basals the discriminant function analysis misclassifies only one, but 15 of the 52 C. dicyclicus plates were assigned to the wrong sample. The 16 misidentifications in 60 plates indicate major morpho- logical overlap between the basals of C. dicyclicus and S. dicychicus. The basals of C. dicyclicus, C. conoideus, and S. dicyclicus are statistically the same, suggesting that only a single species is present, and C. conotdeus is considered a synonym of C. dicyclicus. As men- tioned above, S. dicyclicus and C. dicyclicus also allegedly differ in the number of anal plates. There are two possible interpretations. The difference in anal plates may be real, and a valid taxonomic character. Alternatively, the extra anals of S. dicychcus may be abnormal. The latter alternative is suggested by the following ob- servations. 1. The basals of C. dicyclicus and S. dicyclicus are identical. Only one specimen with the extra anal plates, the holotype of S. dicyclicus, is known. All other specimens which can be or have been reconstructed have the normal carabocrinid numbers of anals. The rarity of the S. dicyclicus anal plate configuration suggests that it is abnormal. 2. Extra anal plates represent a common developmental abnor- mality in dicyclic inadunate crinoids from various families and hori- zons (see Strimple, 1963, pp. 10-13 for review). We have also seen extra anal plates in specimens of C. treadwelli Sinclair from the Bromide Limestone of Oklahoma. 3. Study of the developmental sequences of plates in living and fossil crinoids suggests that the extra anal plates could easily be ex- plained as an ontogenetic abnormality. All of these considerations justify the recombination of C. dicyclicus (including C. conoideus) and S. dicyclicus. The species S. dicyclicus Sardeson, 1899, has nomenclatural priority; the other two trivial names were published in 1925. As Carabocrinus E. Billings (1857, p. 275) has generic priority, the current name of the Twin Cities form becomes Carabocrinus dicyclicus (Sardeson). A full synonymy is given under Carabocrinus. 396 BuLLETIN 304 Carabocrinus magnificus Sardeson from Cannon Falls vs. Carabocrinus magnificus Sardeson from St. Paul The probability of a larger F-ratio falls between 0.10 and 0.05 and 38 out of 95 plates were misassigned by discriminant function analysis. Clearly, there are no statistically significant differences between the specimens of C. magnificus from Cannon Falls and St. Paul, and the samples are considered conspecific. Carabocrinus dicyclicus (Sardeson) vs. Carabocrinus magnificus Sardeson The probability of a larger F-ratio value is much less than 0.005. Obviously two different species are present. All three variables contribute to separating the two species, although plate ornamenta- tion provides the highest degree of contrast (see discriminant func- tion coefficients in Table 1). Only two misidentifications out of 184 plates shows that there is little morphological overlap between the two samples. Clearly, they represent separate species. We also attempted to differentiate the basals of C. dicyclicus (Sardeson) from those of C. magnificus, based only on height and width. The probability of a larger F-ratio equals much less than 0.005, a statistically significant difference. However, a large morpho- logical overlap between the two species is suggested by the misclassi- fication of 41 of 181 plates by the discriminant function analysis. Generally, at any given size, the plates of C. magnificus are more slender than those of C. dicyclicus (Sardeson) (Text-fig. 2). The misidentification data and the regression coefficients indicate that the smaller plates are similar in height and width, but the plates Text-figure 2.— Bivariate graphs for height and width of basals in Twin Cities carabocrinids.

In summary, two species of Carabocrinus lived in the Twin Cities area, C. dicyclicus (Sardeson) and C. magnificus Sardeson; the former dominated the Decorah fauna at St. Paul whereas the latter was most abundant at Cannon Falls. The two forms are most easily distinguished by the ornamentation. C. magnificus possesses a small number of simple and heavy stellate ridges whereas the orna- mentation of C. dicyclicus (Sardeson) is more complex, commonly aligned nodes with or without stellate ridges (see Pls. 19-23, 24). In addition, the plates and dorsal cup of C. magntficus are more slender with respect to overall size than in C. dicyclicus (Sardeson) (see Text-fig. 2, Pls. 19-22, 24). FUNCTIONAL MORPHOLOGY OF CARABOCRINUS DICYCLICUS (SARDESON) Buk Density AND Basic GEOMETRY The calyx of C. dicyclicus (Sardeson) is typical of carabocrinids (see restoration in Text-fig. 3). The dorsal cup is large, ovoid and consists of a small number of plates. In calculating the following volumes and bulk densities, we have adopted the methods of Brower (1973, pp. 283-286); the estimated densities of the soft parts and the endoskeleton are 1.07 and 1.73 gm/cc, respectively. The endoskeleton of living crinoids is covered with a thin epidermis which has been ignored in determination of the volumes and densi- ties because this layer is thin and commonly incompletely developed in many living crinoids. The dorsal cup outline of C. dicyclicus is closely approximated by half of an ellipse of rotation. Although the tegmen is unknown, it is thought to be nearly flat, as in other carabo- crinids with similar calyces. The volume has been computed rather than measured directly by immersion because of the obvious hazards of “dunking” the “plaster-based model-cups” constructed by Sarde- son, and because no complete and uncrushed cups are available. The dorsal cup volume of a mature carabocrinid equals 46.0 cc, assuming that the outline is half of a prolate ellipse of rotation. The dorsal cup plates average 0.2 cm thick. The volume of the thin shell of plates consists of 9.6 cc, and the volume of tissue in the dorsal cup is 36.4 MIppLeE OrpDovIcIAN CRINOIDS: BROWER & VEINUS 399 cc. Because the plates are thin, the volume of tissue is large relative to the cup volume. Consequently the density of the dorsal cup is only 1.22 gm/cc. Narrow radial facets support uniserial and non-pinnulate arms. Judging from the available specimens, the arms branch isotomously and heterotomously above the dorsal cup. The total length of brachials in all rays is 364 cm; there are 2265 plates in all the rays. These figures are relatively small compared to the pinnulate Ordo- vician camerates reported by Brower (1973, pp. 319-323; 1974, pp. 33-40), mainly because of the lack of pinnules in C. dicyclicus (Sar- deson). The number of food-catching tube-feet can also be estimated for a carabocrinid. We assume that the arrangement of the tube feet is the same as in the pinnules of Antedon bifida, in which one long food-catching tube-foot is present in each triad or set of tube feet (Nichols, 1960), and that a carabocrinid brachial bears nine sets of tube feet. The total number of food-catching tube-feet would be about 20,200 for a mature carabocrinid. Because of the lack of pinnules, carabocrinids are characterized by fewer tube-feet than camerate crinoids of the same size (see figures in Brower, 1973, p. 323; 1974, p. 39). In determining the volume of the rays, the arms were approximated by summing the volumes of a series of tapering rod-like segments with elliptical cross sections; as in living crinoids, the soft tissues of the food grooves are estimated to occupy 45 per- cent of the volume of the arms — the plated structures occupy the rest. Total volume of all rays is 25.8 cc, of which 14.2 and 11.6 cc are taken up by the brachials and soft parts, respectively. The den- sity of the arms is 1.43 gm/cc. This is significantly higher than in the calyx, because of the predominance of plates over soft parts. Com- pared to most Ordovician crinoids, the arms of C. dicyclicus are short and small, compared to the dorsal cup. Holdfasts are commonly associated with crushed calyces and loose plates of C. dicyclicus. Based on the frequency and consistency of association, these attachment devices clearly belong to this species, as stated by Sardeson (1899, p. 268). The holdfast of C. magnificus Sardeson is unknown. However, the close morphological similarity between C. dicyclicus (Sardeson) and C. magnificus may indicate that the two forms had similar attachment structures. The holdfast of C. dicyclicus (Sardeson) is flat and disk-shaped (PI. 23). The 400 BuLvetTin 304 device is composed of upper and lower layers, and a narrow inter- space. Presumably, this space was occupied by tissue during life of the animal. The lower layer is a solid disk in which traces of plate sutures are visible in a few specimens (PI. 23, fig. 2). The lower layer must have functioned as a single plate. Prominent ridges are located on top of the lower layer. The five largest ridges are pre- dominant and radiate outward from the central area where the stem was attached; these ridges give rise to numerous branched smaller ridges which increase in number toward the periphery. This pattern was dictated by the roughly circular plan of the lower layer so that new ridges originated as the size of the structure increased. Sardeson (1899, p. 269) interpreted the ridges as branched cirri. Four of the main ridges arise at one level and probably represent the cirri which grew from one columnal. The fifth main ridge appears slightly distal to the others and probably developed from a lower stem plate. Some of the main ridges are hollow and may be homologous with the axial canals in the cirri of many crinoids (Pl. 23, fig. 5). The adjacent ridges are joined together and no traces of the original plate sutures can be found in most specimens. For all practical purposes, the lower layer is a solid plate. Most of the holdfasts were cemented directly to the sea floor although several small specimens were attached to ramose bryozoan fragments that probably lay on the substrate. The upper layer of the holdfast is gently arched and consists of many small, irregular, smooth and obscure plates (Pl. 23, fig. 4). It begins at the beveled margin of the lower layer (PI. 23, fig. 3). The upper plate extends to its junction with the stem. The upper layer commonly is not preserved, but its presence may be denoted by a beveled edge on the lower plate. It is possible but not likely that some of the holdfasts lacked upper layers. The upper layers may be missing for either of two reasons: 1) The upper layer is much thin- ner than the lower, and more susceptible to weathering. 2) Burial in the habitat was usually slow. Consequently, the plated upper layer fell apart after the crinoid died, but prior to burial. Following decomposition and disintegration, the plates were scattered about the sea floor by wave and current action. Compared to the size of the crown, the holdfast is small, with a total volume of 5.7 cc. The shape of the holdfast was approximated as follows: lower layer as a circular disk with a diameter of 4.7 cm Mippie OrpoviciaN CRINOIDS: BROWER & VEINUS 401 and a thickness of 0.2 cm; soft tissues between upper and lower layers as a cone 4.7 cm in diameter and 0.3 cm high; upper layer as a conical shell with a thickness of 0.1 cm and height and diameter of 0.4 cm and 4.7 cm, respectively. A small amount of tissue, 0.71 cc, accounted for 12.5 percent of the volume of the holdfast. The plates represent 87.5 percent of the holdfast. Because of the low ratio of tissue to plates, the holdfast is the most dense part of the crinoid, with a density of 1.65 gm/cc. The stem is poorly known. Two columnals with a diameter of 0.34 cm are attached to the holotype of Strophocrinus dicychicus Sardeson [cup width is 5.0 cm; PI. 20, figs. 10, 12, 13; as mentioned earlier, S. dicyclicus Sardeson is now termed Carabocrinus dicyclicus (Sardeson)]. These columnals are round or obscurely pentagonal with a pentalobate axial canal. Except for these two plates, the stem of Carabocrinus dicyclicus (Sardeson) is unknown. Although num- erous dorsal cup plates and holdfasts are available, no stem type is consistently associated with the species. Basically C. dicyclicus (Sardeson) was a large crinoid attached to stem of extremely small diameter. This suggests that the column was short, and the dorsal cup may have been attached almost directly to the holdfast. It is believed that a long thin stem could not have supported and ele- vated the crinoid above the sea floor. Probably a short stem con- sisting of a few columnals was present. The column was omitted from computations of density and volume because of its presumed small size. The bulk density of the entire carabocrinid can now be esti- mated. The volumes and densities are: Part of crinoid Volume Volume of tissue Density in in cc in cc gm/cc Dorsal cup 46.0 36.4 122 Arms 25.8 11.6 1.43 Crown 71.8 48.0 1.29 Holdfast 5.70 0.71 1.65 Entire crinoid hess 48.7 1.32 The bulk density of 1.32 gm/cc is within the range for extant crinoids. For 16 species of comatulids, the densities range from 1.11 to 1.39 gm/cc with a mean of 1.26 gm/cc (Brower, 1973, p. 284). Densities of fossil crinoids are only available for a few species of Ordovician camerates, for which Brower (1973, p. 284) determined 402 BuLLeTIN 304 a crown density of 1.41 gm/cc. The higher density of camerates re- flects the large volume and mass in the pinnulate arms. The non- pinnulate arms of C. dicyclicus (Sardeson) dictate a lower density. For the carabocrinid, the crown is supported by the holdfast and stem. Inasmuch as the crinoid is partially supported by the sur- rounding sea water, the total densities are somewhat misleading. The portion of the weight of the entire crinoid that must be sup- ported by the substrate depends upon the effective density [bulk density minus density of sea water (1.03 gm/cc)]. For the crown alone this is the weight borne by the holdfast and stem. The effective densities of the crown and entire crinoid of C. dicyclicus (Sardeson) are 0.26 and 0.29 gm/cc, respectively. Moope oF LiFz AND ADAPTATIONS Two possible habits are envisioned for Carabocrinus dicyclicus (Sardeson). In the more probable one, the holdfast was cemented to the substrate and the crown was attached to the holdfast by a stem consisting of a few plates (Text-fig. 3). The segmented column would have allowed flexibility so that the crinoid could sway to and fro in the currents. If the crinoid were attached directly to the hold- fast, the animal would have been rigidly fixed in place. Extremely strong current or wave action could have detached the crinoid from its root. Such a situation probably would have proved fatal. A less likely scenario postulates a partially buried existence in which the embryonic crinoid was attached to some object on the sea floor. As the crinoid grew, currents deposited fossil debris and sedi- ment which eventually buried the holdfast and the base of the cup. This alternative seems less likely for several reasons. All holdfasts are attached to surfaces like bedding planes that were probably ex- posed to the overlying water column during life of the crinoid. The holdfasts and lower parts of the calyces exhibit no evidence of de- formation or warping that might be explained by partial burial. Such deformation and warping are common in pentamerid and other brachiopods which have a partly buried mode of life (see Johnson, 1977; Rudwick, 1970, pp. 91-94). The low bulk and effective densi- ties of the carabocrinids are reasonable adaptations for a substrate- dwelling existence where the crown was supported by the holdfast and stem. Higher densities are probably more useful for a partially- buried life style. For example, brachiopods that are partly buried 403 BROWER & VEINUS MuppLe OrboviciAN CRINOIDS: are commonly thick shelled forms in which the buried region of the shell is greatly thickened for increased stability (Rudwick, 1970, pp. 91-94). This feature is conspicuously absent in C. dicyclicus (Sarde- son). For these reasons, the Twin Cities carabocrinid is thought to buried species. Both be a substrate dweller rather than a partially possibilities are shown in Text-figure 3. The carabocrinids lived in an environment that was highly agi- tated periodically. Some crowns may have been detached from their holdfasts by either or both wave and current action.

The specimen in the foreground shows the most probable mode of life with the holdfast cemented directly to the seafloor. A less likely orientation with the holdfast and part of the dorsal cup buried in the sediment is sketched in the background. The crown is mainly reconstructed from NMNH 43008, which has a height of about 10 cm. The holdfast and stem are schematic. 404 BuLuetin 304 speculation about what might have happened to such a detached animal. The ecology of living crinoids is pertinent (see Fell, 1966 for summary). Extant young comatulids have a stem that is attached to the seabed or some other object during the pentacrinid ontogene- tic phase. Like most Paleozoic crinoids, these are rooted filter feeders. At maturity, the animal sheds the column and assumes a semi-free existence. The animal commonly is attached to the seafloor or some object by the cirri on the calyx base. The crinoids move periodically: some by swimming (e.g., Antedon), and others (like the coma- sterids) by crawling along the substrate. The arms grasp, pull, and lever the animal along during crawling. In swimming, the pinnules are extended on the down or propulsion stroke; this provides a large surface area in contact with the water. The upward or return stroke is slower and the pinnules come together over the ventral sides of the arms to minimize the water resistance. Typically, the arms operate in two groups, half at a time. Variations in the power strokes of different arms allow directed swimming. A detached individual of Carabocrinus dicyclicus (Sardeson) could not have exploited this modern crinoid mode of life for several reasons. 1. There are no grasping cirri on the calyx base. The position of the center of gravity is obviously critical to a detached carabocrinid crown. If the arms were held vertically, the center of gravity would lie along the distal part of the dorsal cup. Spreading the arms would displace the center of gravity into the radial circlet. Thus the crown center of gravity is located so that a detached animal would lie on its side. None of the specimens exhibit any evidence (such as asym- metry) of this living orientation. Clearly this was not the normal life attitude although a few traumatic or fatal accidents may have occurred. 2. Swimming was probably not possible. This conclusion is based on two lines of evidence. First, the carabocrinid arms are short and non-pinnulate. Those of swimming comatulids are longer and pin- nulate. The ratio of arm surface area to mass in carabocrinids seems too small to make swimming a mechanical possibility. Second, living crinoid arms are characterized by muscular articulations which per- mit the rapid movements necessary for swimming. The brachials are Mippie OrpoviciAN CrINOIDS: BROWER & VEINUS 405 hinged, and flexed by ligaments and muscles. The difference between crinoid muscles and ligaments is obscure but both can contract when stimulated by the nervous system. Strictly ligamental articulations as in the cirri react more slowly than do muscular articulations that possess both ligaments and muscles. Swimming comatulids have better developed muscular articulations, with larger muscles and ligaments, than do crawling types (Gislén, 1924, pp. 56, 57, 62-64). Like all early Paleozoic crinoids, the arm articulations of C. dicych- cus (Sardeson) are ligamental (see Van Sant and Lane, 1964, pp. 34-37, for summary on articulation in Paleozoic crinoids). The liga- ments of carabocrinids are also short and a distinct transverse ridge is lacking. C. dicyclicus (Sardeson) could have moved the arms, but certainly not rapidly enough to swim. 3. The possibility of crawling is more difficult to refute. Crawling requires flexible arm tips which can provide leverage and grasp objects on the seafloor. Judging from the few preserved exam- ples, the carabocrinid arms may have been flexible enough for slow crawling. This is consistent with the ligamental articulations seen in isolated brachials. The suggested life style of C. dicyclicus (Sardeson) is as follows. The disk-shaped holdfast was cemented directly to the seafloor and the crown was attached to the holdfast by a short stem. The ap- proximate elevations of an adult above the substrate are: base of calyx, less than one cm; top of dorsal cup, about five cm; arm tips, roughly 10 cm (Text-fig. 3). Detachment of the crown from the stem was probably fatal although a detached individual may have been able to crawl to a place of refuge. Srm1Lar ADAPTATIONS IN OTHER CRINOIDS Numerous crinoids have exploited a filter-feeding mode of life at low levels. Their adaptations are varied and can be divided into the following types. No attempt is made to list all species in each category: a few well-illustrated forms are tabulated. The categories range from the most (Types 1 and 2) to the least sedentary (Type 6). 1. The simplest solution to the problem is to shorten the stem between the calyx and holdfast. Examples are Carabocrinus dicych- cus (Sardeson), Euspirocrinus spiralis Angelin from the Silurian (see Ubaghs, 1953, p. 721, fig. 112; Springer, 1913, p. 174, fig. 267), 406 BuLveTin 304 Eugeniacrinus caryophyllatus Miller from the Jurassic (Ubaghs, 1953, p. 764, fig. 161; Springer, 1913, p. 240, figs. 345a, b), Toryno- crinus granulatus (Jaekel) from the Cretaceous (Ubaghs, 1953, p. 709, fig. 79), Hemicrinus spp. from the Mesozoic (Arendt, 1974, p. 45, text-fig. 5), and Phyllocrinus sabaudianus Pictet and Loriol from the Mesozoic (Arendt, 1974, p. 52, text-fig. 52). Most of these crinoids are massive, thick-plated types with heavy stems that lived in agitated environments. Although also found in a rough water habitat, Carabocrinus dicyclicus (Sardeson) is an exception, with its thin-plated calyx and narrow stem. The thin-plated calyx was dic- tated by the small stem. The carabocrinid probably was not fully adapted to life in agitated waters. 2. Other crinoids went one step further. The stem was lost, and the calyx base was cemented directly to the seafloor or some object. Examples are Cyathidiwm holopus Steenstrup from the Cretaceous (Ubaghs, 1953, p. 724, figs. 113a, b; Miiller, 1963, p. 393, figs. 533a, b), C. depressum Sieverts from the Cretaceous (Miiller, 1963, p. 393, figs. 531, 532), Hemibrachiocrinus manesterensis Arendt from the Cretaceous (1974, p. 54, text-figs. 10a, b), Brachimonocrinus simplex Arendt from the Cretaceous (1974, p. 54, text-figs. 10c, d), Dibrachiocrinus solovject Arendt from the Cretaceous (1974, p. 54, text-figs. 10d, e), Holopus rawsont Gray and H. rangu d’Orbigny, both Recent (Ubaghs, 1953, pl. 764, fig. 165; Springer, 1924, pls. 1-3), and Edriocrinus holopoides Springer from the Devonian (see Springer, 1920, pp. 443-452, pl. 76, figs. 22, 23). Some of these crin- oids are comparatively high and erect, like FE. holopoides, while others present very low profiles (e.g., Cyathidium depressum). In all, the arms are short and massive, and the dorsal cup is low and heavy. In some, plates are fused together (Edriocrinus). Other forms probably fail to develop certain plates during ontogeny (Cyathidium and Holopus). Springer (1920, pp. 443-452) surveyed the available data on the life of Edriocrinus. All young animals were cemented to the seabed. Some, like E. holopoides, retained this habit through- out life, and adults of these taxa show obvious evidence of cementa- tion. Other Edriocrinus, e.g. E. sacculus Hall and E. pocilliformis Hall (see Goldring, 1923, pl. 58, figs. 1-15), lost all vestiges of orna- mentation and developed rounded bases as adults (see discussion below). Muppte Orpovician CrINOIDS: BROWER & VEINUS 407 3. The recumbent stemmed calceocrinids of the Paleozoic were studied by Brower (1966) and Kesling and Sigler (1969) (see Cremacrinus punctatus Ulrich and C. arctus Sardeson here). The stem in these forms serves as a runner along the seabed. In the rest- ing position, the hinge is closed and the crown lies parallel to the stem. For feeding, the hinge is opened, which elevates the crown so that the arms are roughly at a right angle to the stem. Breimer and Webster (1975) thought that calceocrinids with long stems might have been lifted into the water by currents when the arms were opened so that the crown operated as a “submarine kite.” 4. Several Ordovician hybocrinids may have also had recum- bent stems, either embedded in the substrate or running along the surface. Examples are Hybocystis problematicus Wetherby and Hybocrinus tumidus E. Billings (see Strimple, 1975) and the speci- men of H. punctatus (Miller and Gurley) figured by Brower and Veinus (1974, p. 33, pl. 5, fig. 2). 5. Some Paleozoic crinoids were probably “bottom sitters.” Two examples are Agassizocrinus lobatus Springer (Ettensohn, 1975) and Cryphiocrinus Kirk (Strimple, 1977). Juveniles of both forms pos- sessed stems that were lost in the adult stages. Mature specimens of Edriocrinus sacculus Hall and adult FE. pociliformis Hall also belong to this category (see Springer, 1920, pp. 443-452 for mode of life; Goldring, 1923, pl. 58, figs. 1-15 for drawings). Young animals were cemented to the substrate but the older individuals have rounded bases and no trace of a stem scar. The proximal part of the calyx is mostly solid calcite; this must have displaced the center of gravity downward and increased the stability. The crinoids are visualized as sedentary, with the cup base either on the surface or partly buried in the sediment. Kirk (1911, pp. 99, 107, 113, 114) believed that these forms were partly eleutherozoic. Probably the animals possessed some ability to move by swimming or crawling. The latter seems more likely due to the predominantly or wholly ligamental arm articulations that would result in slow arm move- ments. These are thick-plated species with arm surface area to mass ratios too small for effective swimming. 6. Living comatulids have attained a high degree of mobility. Adult individuals shed the larval column and assume a more or less free existence. Most of these crinoids are attached by cirri along the 408 Bu LetTin 304 cup base. Some cling to the substrate or nest in cracks and crevices. Others prefer to grasp upright objects like sea-fans. Periodically the animals move from place to place by swimming or crawling (see Fell, 1966 for summary of their ecology; Clark, 1921, pls. 6-11, 22, 52-54; 1915, figs. 76-125 for illustrations). These various adaptations were commonly results of convergent evolution. Similar adaptations are found in lineages of Paleozoic and post-Paleozoic crinoids belonging to many different families and orders. Food gathering is obviously critical to a crinoid, and Magnus (1967) estimated that a living comatulid spends over half of its lifetime in this activity. Unfortunately, many of the variables which affect feeding in crinoids, such as the amount of plankton in the water and metabolic rates, cannot be measured for fossil forms (Brower, 1973, pp. 318, 319; 1974a, pp. 33, 34). Probably the most important morphological parameters are the amount of tissue that must be supplied with food, the number of food-catching tube feet and the area covered by the food gathering system. For C. dicychicus (Sardeson) the first character is estimated by the total volume of soft parts, which would include both soft tissues and fluid-filled coelomic spaces; the number of tube feet was previously worked out. Owing to geometrical complexity, it is impractical to measure the area covered by the arms or food-gathering system and the length of the arms is given instead.

Brower (1973, pp. 319-323; 1974a, pp. 33-40) treated ratios of length of food-gathering system to calyx volume for some Ordo- Mippie OrpoviciANn CrINoIps: BROWER & VEINUS 409 vician camerate crinoids. These data cannot be compared with the carabocrinid figures because the calyx volume was used rather than the volume of tissue. The most appropriate data were presented by Gislén (1924, pp. 282-286) who measured the length of the food- gathering system and total volume for 16 species of extant coma- tulids. Because the comatulids are pinnulate, the length of the food- gathering system is the sum of the lengths of the arms and pinnules. The arms of C. dicyclicus (Sardeson) lack pinnules so that the length of the food-gathering system is the same as that of the arms. We computed the ratio of food-gathering system length in cm to total volume in cc from these data. The summary statistics for the coma- tulids are listed below. Standard Variable Range Mean deviation Total volume in cc 0.47-73.1 13.9 21.0 Length of food gathering system in cm 195-10,300 2740 2790 Ratio of length of food gathering system to total volume 121-1000 398 256 The equivalent figures for C. dicyclicus (Sardeson) are: total volume, 77.5 cc; length of arms, 364 cm; and ratio of length of arms or food-gathering system to total volume, 4.70. For the comatulid data, these parameters are dependent on size with the following re- gression lines and correlation coefficients: 0.775 Length of food gathering system = 454 (Volume) Correlation coefficient = 0.894 and -0.463 Ratio of length of food gathering system to volume = 662 (Volume) Correlation coefficient = —0.662 Thus the ratios decrease in progressively larger comatulids. Most of the volumes of the comatulids are considerably smaller than those of the carabocrinid. In order to minimize the effect of size, only the data for the four largest comatulids are tested against those of C. dicyclicus (Sardeson). The summary statistics for the ratio of length of food gathering system to total volume for the comatulids are: Mean Range Standard deviation Standard error of mean 149 121-196 32.8 16.4 410 BuLLeTIN 304 The 95% and 99% confidence limits for the mean for this ratio in the four comatulids are from 96.8 to 201 and from 53.2 to 245, respectively. The ratio of 4.70 for C. dicyclicus (Sardeson) lies well below the confidence belts of the largest comatulids. Clearly, as far as food-gathering capacity is concerned, the comatulids and the carabocrinid belong to different statistical populations. This sug- gests to us that comatulids and C. dicyclicus (Sardeson) did not exploit the same feeding strategies. Several recent papers have discussed feeding in living and fossil crinoids ( Breimer, 1969; Lane and Breimer, 1974; Meyer and Lane, 1976). Most living species form dense filtration networks and exploit what Lane and Breimer (1974) termed full or partial mucus-net feeding. The filtration network or fan is constructed by arms and pinnules that secrete a mucus net. Small food particles (about 0.4 mm or less in diameter, according to Meyer and Lane, 1976) that impinge on the filtration fan are trapped by the mucus and tube feet and eventually conveyed along the food grooves to the mouth by the tube feet and cilia. In addition to living crinoids, camerates, all of which have pinnules, and pinnulate inadunates were probably mucus-network feeders (Lane and Breimer, 1974; Meyer and Lane, 1976). In agitated environments, most of the food supply travels parallel to the substrate and the filtration net is held vertically (Breimer, 1969; Lane and Breimer, 1974; Meyer and Lane, 1976). Under still water conditions the food consists of a vertical rain of plankton and organic detritus. Crinoids in these habitats probably spread their arms horizontally to form a collecting bowl (Breimer, 1969). Some crinoids which lived in alternating quiet water and agitated environments may have used both feeding postures (Brower, 1973, pp. 269-271, 283-290). Lane and Breimer (1974) thought that many flexibles and non- pinnulate inadunates were limited mucus-net feeders, but Meyer and Lane (1976) postulated that feeding in these crinoids was analogous to that of Recent basketstars. Basketstars dwell in agitated areas where they erect parabolic filtration nets (Meyer and Lane, 1976, pl. 1, fig. 1; Macurda, 1976, fig. 1). The basketstar net is an open mesh- work in contrast to the much denser network of extant crinoids. Currents carrying food particles flow through the arms of basket- stars. Tube feet and mucus do not function in feeding of basketstars. Mippie OrpovictaN CRINOIDS: BROWER & VEINUS 411 Instead large food particles (10 to 30 mm long) are caught by the flexible ramules of the arms and impaled on hooks on the arms (Meyer and Lane, 1976; Macurda, 1976, fig. 1). The food particles are transferred to the mouth by bending the arms and pulling them through the oral papillae. Living crinoids and basketstars can co- exist without competing for food because the food particles eaten by the two groups are not the same size (about 0.4 mm and smaller for the crinoids, and 10-30 mm for basketstars). As mentioned above, the low ratio of food gathering system length to total volume of C. dicyclicus (Sardeson) suggests that the animal utilized a different feeding strategy than do full mucus-net feeders like pinnulate living and fossil crinoids. This is suggested by the non-pinnulate arms, which could not have formed a complete mucus-bearing network. This is because the gaps between the arms would have been too large for the mucus strands to be maintained in the agitated environment where the carabocrinids are found. Four observations suggest that C. dicyclicus (Sardeson) and basketstars did not possess the same feeding habits. The arm branches of the carabocrinids were not flexible enough to wrap around and trap food particles. Hooks are lacking in the arms of the Twin Cities crinoid. Carabocrinids bear food grooves and tube feet which were suitable for food gathering; the tube feet of basketstars are not in- volved in feeding. It is difficult to see how large food particles could be carried to the subtegminal mouth of most Paleozoic crinoids. The main analogy that we draw between basketstars and the carabocrinids is based on the coarse meshwork of the arms. This homeomorphy suggests that, like basketstars, carabocrinids probably ate larger food particles than did comatulids with their densely- packed filtration networks. C. dicyclicus probably trapped large food particles directly with the tube feet, as suggested by Lane and Breimer (1974) for some small inadunate crinoids with nonpinnulate and unbranched arms. Although the food particles of C. dicychicus (Sardeson) probably were larger than the 0.4 mm and smaller par- ticles eaten by crinoids with full filtration networks, it is doubtful that these reached the 10 to 30 mm size range preferred by basket- stars, because the food grooves of C. dicyclicus are not wide enough to transport such large material. We visualize food particles up to about 1.0 to 2.0 mm in diameter for the Twin Cities form. However, 412 BuLieTin 304 it is misleading to consider food particles in terms of linear dimen- sions, because volume or mass is involved in the amount of nourish- ment contained in a piece of food. A small increase in the diameter of a food particle can result in a large change of volume. For example, a spherical food particle with a diameter of 1.0 mm has 15.6 times the volume of a particle 0.4 mm in diameter whereas the volume for a particle of 2.0 mm diameter is 125 times larger than the 0.4 mm one. We believe that many nonpinnulate flexible and inadunate crinoids used the feeding strategy outlined here for carabocrinids.

Pl. 13, fig. 6; Text-fig. 4 Remarks. — Two partial crowns that are poorly preserved and embedded in matrix are tentatively placed in Archaeocrinus. Because many calyx plate sutures are not visible, the reconstructed plate diagrams in Text-figure 4 are conjectural. The calyx structure indi- cates the crinoids should be assigned to Rhaphanocrinus (Wachs- muth and Springer, 1885, p. 98(320)) or Archaeocrinus (Wachs- muth and Springer, 1881, p. 189(363)). The arms of the Twin Cities crinoids are biserial and branched as in Archaeocrinus rather than uniserial and unbranched like in Rhaphanocrinus. Consequently, the two specimens are assigned to the former genus. The most similar archaeocrinids occur in the Trenton of Canada; these include A. lacunosus (E. Billings) (1857, p. 261; see Wachsmuth and Springer, 1897, p. 255, pl. 10, fig. 1) and A. microbasalis (E. Billings) (1857, p. 264; see Wachsmuth and Springer, 1897, p. 256, pl. 10, figs. 2a-c). Both of the Canadian animals possess stellate plates rather than the smooth plates of the Twin Cities crinoids. The Twin Cities specimens probably belong to an undescribed taxon, but a new species is not proposed because the available material is poorly preserved. Figured specimens. — UM 9265.

The following generic diagnoses are preliminary and slightly different from those to be published in the Treatise. Glyptocrinus Hall (1847, p. 281). Type species, G. decadactylus Hall. Arms unbranched, composed of uniserial or cuneiform brachials; arms ranging from two to four per ray; secundibrach 2 is axillary in Text-fig. 4 Plate diagrams for Archaeocrinus sp. Figured specimens, UM 9265, plate diagrams conjectural, both specimens X 3.5, Decorah Shale, Bed 4 of Sardeson, Twin Cities Brick Plant, St. Paul. A. — Specimen with arms on left side of slab. B. — Dorsal cup with stem and small part of arms. Interbrachial plates stippled. 414 BuLLeTiIn 304 rays with more than two arms; a prominent pinnule is located on the interray side of secundibrach 2 in arms where this plate is not axil- lary. Pycnocrinus Miller (1883, p. 219). Type species, G. dyert Meek. (Glyptocrinus shafferi Miller was originally designated as type species but G. shaffert represents a junior synonym of G. dyer Meek, as discussed below.) Arms consisting of uniserial or cuneiform brachials; arms with prominent pinnule located on interray side of secundibrach 2; arms branching once or twice above the calyx; axil- lary secundibrach ranges from a minimum of ¢ to about 20 in most species; some forms have arms which branch again on the terti- brachs; total number of arm branches varies from four to eight in each ray. Periglyptocrinus Wachsmuth and Springer (1897, p. 277). Type species, P. billingst Wachsmuth and Springer. Arms biserial, two or four unbranched arms in each ray; if four arms occur in a ray, secundibrach 2 is axillary. Genus GLYPTOCRINUS Hall, 1847 Glyptocrinus tridactylus, n. sp. Pl. 12, fig. 5; Text-fig. 5E Diagnosis. — A species of Glyptocrinus with three arms in each ray; axillary brachials comprising primibrach 2 and secundibrach 2 of one of the half-rays; within a single ray, one half-ray with two arms, the other bearing only a single arm and a large pinnule; arms uniserial and unbranched. Calyx ornamentation of stellate and median-ray ridges. Arms covered with fine sinuous ridges. Description. — Calyx globose with rounded sides and_ basal flange, height/width 1.0. Calyx ornamentation of median-ray and stellate ridges. Unweathered portions of arms characterized by fine sinuous ridges. Basal circlet low, with five pentagonal basals; height/width of basals equals 0.3. Radials large, hexagonal, height/width 0.8. Primi- brachs almost as large as radials. Primibrach 7 hexagonal, height/ width 0.7. Primibrach 2 axillary, septagonal, height/width 0.7. In each ray, one half-ray remaining unbranched, other branching on secundibrach 2. Distal fixed-brach consisting of secundibrach J or 2. Fixed-secundibrachs roughly equidimensional; height/width ranging from 0.9 to 1.0. MippLE OrpbovICcIAN CRINOIDS: BROWER & VEINUS 415 Interbrachials of lateral interrays not strongly depressed, plates regular, one large plate in proximal range, roughly equidimensional; two plates in each of the three distal ranges; height/width ranging from 1.5 to 2.0; interbrachial 2 range ending at level of primaxil. Intersecundibrachials not present, but proximal margins of secundi- brachs / of the same ray are joined. Arms three per ray, not completely known, unbranched, com- posed of uniserial pinnulate brachials. Brachials with protuberant pinnule facets; height/width varying from 1.0 to 1.5. Pinnules long, heavy relative to size of arms. Stem facet round with circular axial canal. CD interray, tegmen, stem and rooting device unknown. Remarks. — This form is only known from a single specimen, a young crown with a calyx height of about 3.0 mm. Three rays are visible, each with three arms. Despite the immaturity of the holo- type, G. tridactylus, n. sp. can easily be separated from all glypto- crinids by the presence of three unbranched uniserial arms in each ray. The axillaries consist of primibrach 2 and secundibrach 2 of one half-ray; the other half-ray remains unbranched. The holotype could be an abnormal specimen of a glyptocrinid with two or four unbranched arms in a single ray. However, this seems unlikely be- cause the number of arms per ray is a stable character in most large populations of glyptocrinids which we have examined, such as G. decadactylus Hall and Pycnocrinus dyert (Meek). Consequently Glyptocrinus tridactylus, n. sp. is thought to be a separate and dis- tinct form. This crinoid provides a morphological link between glyptocrinids with two unbranched arms in each ray and those with four unbranched arms in a ray where secundibrach 2 is the axillary. Species with two arms per ray are: G. pustulosis Kolata (1975, p. 50, pl. 9, fig. 8, text-fig. 15) and G. charltoni Kolata (1975, p. 49, pl. 9, figs. 2-4, 6, 7) [Black River forms]; G. ornatus E. Billings (1857, p. 269; see E. Billings, 1859, p. 60, pl. 9, fig. 2a; Wachsmuth and Springer, 1897, p. 274, pl. 20, figs. 6a, b) and G. circwmcarinatus Parks and Alcock (1912, p. 43, pl. 4, figs. 2,3) [Trenton taxa]. In G. circumcarinatus, one arm seems to branch on secundibrach 2 al- though this is probably an abnormality; the calyx ornamentation of G. circumcarinatus can easily be distinguished from that of G. tri- dactylus, n. sp.. Bassler and Moodey (1943, p. 602) treated G. 416 BuLuetin 304 mercerensis Miller and Gurley (1894, p. 28, pl. 2, fig. 23) as a syno- nym of Periglyptocrinus priscus E. Billings. According to the orig- inal illustration, G. mercerensis has uniserial arms. We have exam- ined the two types, UC 603, which are poorly preserved silicified specimens from Mercer County, Kentucky. The proximal parts of the arms are uniserial as in both Glyptocrinus and Periglyptocrinus but the structure of the distal part of the arms cannot be determined. Thus, G. mercerensis could be placed in either Glyptocrinus or Periglyptocrinus. UC 603 contains two specimens. The better of the two was illustrated by Miller and Gurley. This crinoid has a rounded cup base and a basal concavity; the calyx shape is different from that of P. priscus and this specimen is not conspecific with P. priscus. The second specimen in UC 603 is a long and slender calyx with in- determinate plate structure which we regard as unidentifiable. Con- sequently, we designate the specimen figured by Miller and Gurley as lectotype of Glyptocrinus? mercerensis. The only glyptocrinid with four unbranched arms in each ray where secundibrach 2 is axillary, is G. decadactylus Hall (1847, p. 281, pl. 77, figs. la-f; pl. 78, figs. la-u; see Meek 1873, p. 30, pl. 2, figs. 5a, b; Wachsmuth and Springer, 1897, p. 270, pl. 6, fig. 12; pl. 20, figs. 4a-e; pl. 21, figs. 4a, b) from the Upper Ordovician. How- ever, this configuration is also found in primitive species of Also- crinus which were derived from G. decadactylus (Brower, 1973, pp. 432-438).

Ornamentation of median-ray ridges; calyx plates covered with either or both small nodes and short ridges, some specimens with fine short ridges located on margins of calyx plates; ridges oriented at right angles to plate sutures. Basals pentagonal, short, height/width 0.4. Radials large, hexa- gonal, height/width 0.9. Two primibrachs present, almost as large as radials, height/width 0.9; primibrach J hexagonal; primibrach 2 axillary with six or seven sides. Distal fixed-brachial variable, usually a proximal tertibrach. Number of secundibrachs commonly six, less commonly four or five; two proximal plates, large, with six or seven sides, height/width about 1.2; distal four secundibrachs much smaller and wider relative to height, with five to eight sides, height/width ranging from 0.4 to 0.6; secundibrach 6 generally axillary, penta- gonal, height/width about 0.5. From three to 11 tertibrachs may be fixed into the calyx; fixed tertibrachs similar to distal secundibrachs, height/width varying from 0.3 to 0.1. Lateral interrays with eight or nine ranges of interbrachs; inter- brachial areas slightly depressed compared to rays, plates regular; plates smaller in distal direction; height/width of plate ranging from about 1.0 to 0.7; proximal range with one plate; second range of two plates, terminating at level of primaxil or secundibrach J; third range with two or three smaller plates ending at proximal secundi- brach level; next two higher ranges of interbrachs with two or three plates; higher ranges bearing from five to seven plates, gradually merging into tegmen; prominent fixed pinnule on secundibrach 2; other fixed brachials may also have fixed pinnules. Intersecundibrachial areas depressed below adjacent rays, proxi- mal range with one plate at the secundibrach J level; about five higher ranges present, each with two or three plates. CD interray partially known, primanal between primibrachs I of Cand D rays; primanal followed by about seven large basically hexagonal anal series plates; anal series not strongly differentiated from the adjacent CD interray interbrachs.

Tegmen partly preserved, composed of numerous plates, not Mrpp.eE OrpbovIcIAN CRINOIDS: BROWER & VEINUS 419 strongly lobate. Ambulacrals numerous, polygonal, regular, arranged in rows of two plates, smaller than interambulacrals. Arms four per ray, consisting of uniserial, cuneiform, and im- mature biserial brachials. Brachials much wider than high; height/ width averages about 0.2 or less; pinnule facets small, not strongly protuberant. Pinnules closely spaced, long and slender, consisting of elongate pinnulars. Column facet round. Stem only definitely known from a poorly preserved imprint associated with UM 3489; column round, with nodose columnals. Stem segments that probably belong to this species are round, individual columnals with sharp protuberant ridges that frequently have crenulate or nodose edges, columnals with fine horizontal striae that probably represent growth lines. Attachment device not known. Remarks. — This species is based on two more or less well- preserved calyces and a crushed crown. The crown is interesting be- cause of the unusual type of preservation. The shape of the slab with the crinoid indicates that it was found in the sediment that filled the living chamber of a large straight nautiloid. Obviously the animal did not live there and it must have been transported with essentially no disarticulation. Rapid decapitation, transportation, and burial are denoted by the nearly intact crown. The probable sequence of events began with breakage of the stem, perhaps by a storm. Subsequently the crinoid was washed into the living chamber of the cephalopod where it was deposited. Perhaps the sediment originated as a mudflow that decapitated, transported, and buried the crinoid. Several stem segments may belong to this form. Unfortunately the only direct trace of the stem is the imprint seen below the crown (UM 3489). This imprint is round with nodose columnals. The only stem segments that possess these features are those of UM 9266, and 9370-9372. Although these were not found with the calyces and crown, the similarity of morphology suggests that the stem frag- ments belong to P. sardesom, n. sp. The new species is most similar to P. marginatus (E. Billings) (1857, p. 260; 1859, p. 59, pl. 9, fig. la; see Wachsmuth and Springer, 1897, p. 275, pl. 20, fig. 2) from the Trenton of Canada. Both species possess four arms in each ray in which secundibrach 420 BuLueTIN 304 6 is usually axillary and the shapes of the calyx plates are similar. The presence of rims along the margins of the calyx plates separates the Canadian crinoid from P. sardesoni, n. sp. P. dyert (Meek) and allied forms from the Maysville of the Cincinnati area also show four arms in each ray. The synonymy of these crinoids is complex and in need of revision. P. dyert was estab- lished by Meek (1872, p. 314; 1873, p. 32, pl. 2, figs. 2a, b). Many similar taxa from the same horizon were subsequently proposed by other workers, some of which represent juvenile crinoids; these are P. shaffert germanus (Miller) (1880, p. 233, pl. 7, figs. 2, 2a) and P. shaffert (Miller) (see 1880, p. 233, pl. 7, figs. 3a-c). Wachsmuth and Springer (1897, pp. 271-273, pl. 20, figs. la-c; pl. 21, figs. 3a-f, 6) studied many glyptocrinids from the Maysville and concluded that P. shafferi and P. shafferi germanus were growth variants of P. dyeri. These findings were confirmed by the statistical studies of Brower (1974b, p. 13, fig. 3). Accordingly P. shafferi and P. shaffert germanus are placed in the synonymy of P. dyeri. Subspecies based on adult crowns that are also similar to P. dyeri include P. dyeri sub- laevis (Miller) (1878, p. 103, pl. 3, fig. 2) and P. dyeri subglobosus (Meek) (1872, p. 316; 1873, p. 34, pl. 2, fig. 2c). These crinoids oc- cur with P. dyeri and may not constitute valid subspecies, although they have not been examined statistically. Like P. sardesoni, n. sp., the P. dyeri species group bears four arms in each ray. In the Twin Cities crinoid, secundibrach 6 is axillary; the axillary of the Cincin- nati forms ranges from secundibrach 9 to 15. The Canadian P. ramulosus (E. Billings) (see Wilson, 1946, p. 28) and P. ottawaensis (Wilson) (1946, p. 27) are easily distin- guished by their arm branching pattern. Four arms are present in each ray of P. sardesoni, n. sp., but the arms of the Canadian taxa branch repeatedly, producing roughly eight arms in each ray. The Cincinnatian species Glyptocrinus decadactylus (see Wachsmuth and Springer, 1897, p. 270, pl. 6, fig. 12; pl. 20, figs. 4a-e; pl. 21, figs. 4a, b) also exhibits four arms in a ray but the arms bi- furcate on secundibranch 2 in contrast to secundibrach 6 in Pycno- crinus sardesomt, n. sp. Specific name.— sardesoni in honor of F. W. Sardeson, who contributed greatly to knowledge about Middle Ordovician crinoids from the Twin Cities area.

Pl. 12, fig. 6; Text-fig. 5D Diagnosis. — A species of Pycnocrinus with two main arms in each half-ray; half-rays branch isotomously several times; proxi- mal branch located on secundibrach // to 24; distal axillary varies from tertibrach 8 to 32; roughly eight arms in each half-ray. Dorsal cup with sharp median-ray ridges; sharp ridges also link the ad- jacent radials; interray plates and lateral margins of ray plates with sharp nodes. Description. — Calyx not completely known, elongate, with conical base and straight sides, height/width 1.3. Ornamentation of sharp median-ray ridges on basals, radials, and primibrachs; ad- jacent radials linked by strong sharp ridges; CD interray with sharp ridge located on primanal and anal series; sharp ridges also con- necting primanal with adjacent C and D ray radials and proximal primibrachs; interray plates and lateral margins of ray plates bear- ing sharp nodes, plates somewhat swollen. Basal circlet high, with five pentagonal basals; height/width of basals is 0.6. Radials large, hexagonal, height/width about 1.0. Primibrachs nearly as large as radials. Primibrach J hexagonal, height/width about 1.2. Primibrach 2 axillary, with seven or eight sides. Distal fixed-brachial probably secundibrach 2 or 3. Proximal secundibrachs large, with six or seven sides, height/width about 1.0. More distal secundibrachs smaller and wider relative to height; height/width ranging from 0.7 to 0.5. Interbrachials of lateral interrays not fully preserved, depressed, plates regular. Proximal range with one large hexagonal plate, height/width 1.0. Second range has two hexagonal or septagonal plates that terminate at the primaxil level; plates smaller than interbrachial 7, height/width approximately 0.9. Higher ranges of about three plates each, plates with five to eight sides; height/width varying from 1.0 to 1.8. 422 BuLueTin 304 Intersecundibrachs strongly depressed compared to adjacent rays, proximal range including one plate that ends at the secundi- brach 2 level; second range of two plates; higher ranges not seen. Only proximal portion of CD interray known. Primanal in glyptocrinid position between the primibrachs J of the C and D rays, primanal large, septagonal, followed by a central anal series plate and two smaller CD interray plates on the flanks. Anal series plates large and hexagonal. Other details of CD interray not ob- served. Tegmen not known. Arms two per ray, pinnulate, consisting of unserial and cunei- form brachials; each half-ray branching several times isotomously; proximal branch from secundibrach // to 24; distal axillary from tertibrach 8 to 32. Brachials variable, mostly uniserial and pinnu- late. Uniserial brachials slightly wedge-shaped, extending across the entire arm, height/width about 0.3 or 0.4. Cuneiform brachials pinching out before reaching the side of the arm opposite the pin- nule facet; those brachials immature biserial. Pinnule facets protu- berant; face of facet oriented vertically. Pinnules long, slender, with round backs; proximal parts of pinnules widely separated; pinnulars from equidimensional to elongate plates with height/width about 2.0. Column facet round with pentalobate axial canal; column and root not preserved. Remarks. — This species is represented by one fairly well-pre- served crown. The pattern of arm branching denotes that P. multt- brachialis, n. sp. is allied to the Canadian Ordovician species P. otta- waensis (Wilson) (1946, p. 27; see E. Billings, 1859, p. 57, pl. 7, fig. 2a; Wachsmuth and Springer, 1897, p. 273, pl. 20, figs. 5a, b) and P. ramulosus (E. Billings) (see Wilson, 1946, p. 28; E. Billings, 1859, p. 57, pl. 8, fig. la). All taxa have two main arms in each ray that bifurcate repeatedly so that about eight arm branches are present in each ray. According to Wilson, although the two Canadian taxa are closely related, P. ottawaensis is distinguished from P. ramulosus by larger size and the presence of five or six secundi- brachs rather than four. The Twin Cities form can be separated from the Canadian crinoids by the ornamentation. P. multibrachiahs, n. sp. possesses sharp median-ray ridges, sharp ridges connecting the Mippie OrboviciAN CRINOIDS: BROWER & VEINUS 423 adjacent radials and prominent nodes on the plates. P. ottawaensis and P. ramulosus show smooth plates and broad median-ray ridges. Although all Canadian specimens that we have seen are flattened, the calyx shape of P. multibrachialis, n. sp. is probably narrower than in the Canadian crinoids. The calyx morphology of the new species resembles that of the P. dyeri (Meek) species group. As stated in the discussion of P. sardesont, n. sp., the P. dyeri group is characterized by four arms in each ray where the axillary ranges from secundibrach 9 to 15. In P. multibrachialis, n. sp., each main arm branches several times so that approximately eight arms are found in each ray. Specific name.— multibrachialis, in reference to the many brachials as a result of the repeated arm branching. Holotype. — NMNH 42146. Occurrence. — Decorah Shale: St. Paul.

Pl. 12, figs. 1-4; Text-fig. 6 Diagnosis.— A species of Periglyptocrinus with two biserial arms in each ray; dorsal cup ornamentation of median-ray ridges, stellate ridges, and small nodes on plates; pinnules bearing small spines or nodes. Description.— Calyx conical, with slightly rounded sides, height/width 1.0. Ornamentation of sharp median-ray ridges; strong stellate ridges located on proximal part of cup up to level of primi- brachs; scattered nodes also at this level; stellate ridges lacking on distal part of calyx, but many nodes present. Basals pentagonal, height/width 0.8. Radials large, hexagonal, height/width 0.9. Primibrachs two, nearly as large as radials; primibrach J hexagonal, height/width 1.0; primibrach 2 with six or seven sides, axillary, bearing secundibrachs, height/width 1.0. Distal fixed-brachial from secundibrach 4 to 8. Proximal two secundibrachs irregularly hexagonal; height/width from 0.8 to 0.9. Distal secundi- brachs shorter and wedge-shaped, height/width about 0.4.

Primanal in glyptocrinid position between proximal primibrachs of C and D rays, primanal septagonal, followed by three plates; central plate part of anal series; the two flanking plates are CD interray interbrachials. Anal series with strong median-ray ridge, consisting of large hexagonal plates. CD interray interbrachials smaller than adjacent anal series plates, one plate in proximal ranges, one or two plates in more distal ranges. Tegmen consisting of numerous plates, strongly lobate with raised ambulacral areas and depressed interambulacrals. Ambulacrals nodose, arranged in rows of two plates. Interambulacrals generally smooth, sometimes bearing small nodes, larger than ambulacrals. Arms two per ray, long, slender, composed of immature biserial or mature biserial plates. Immature biserial plates with curved, convergent proximal and distal margins. Mature biserial brachials with parallel proximal and distal margins; inner margins sharply separated from proximal and distal ones, converging sharply, pro- ducing chevron or zig-zag suture between brachials on opposite sides of arms; height/width of brachials about 1.3 to 1.5. Pinnules long and slender, separated by wide gaps; pinnules with many small nodes or short spines. Stem facet round; column and rooting device unknown. Remarks. — Two specimens are definitely assigned to this new species. The holotype, UM 9260a, is a complete crown whereas the paratype, UM 9260b, is a dorsal cup. A third crinoid, UM 9260c, a poorly preserved partial crown in matrix, may also belong to this species. P. spinuliferus, n. sp. is most closely related to P. priscus (FE. Billings) from the Middle Ordovician of Ontario. Both forms show two biserial arms in each ray and similar dorsal cups with the same type of ornamentation. Some confusion exists about the orna- mentation of P. priscus. E. Billings (1857, p. 257; 1859, p. 56, pl. 7, figs. la-f) described and illustrated the holotype, GSC 1522, as if the 426 Bu LvetTin 304 plates were smooth except for median-ray ridges. Wachsmuth and Springer (1897, pp. 278, 279, pl. 21, fig. 2) pictured the type with smooth plates but their description listed median-ray ridges and pustulose plates. Parks (1909) described a specimen (ROM 649T) from another locality in the Middle Ordovician of Ontario, in which the complete ornamentation consists of median-ray ridges and stel- late ridges in conjunction with small nodes on the plates. As men- tioned above, this is the same type of ornamentation as in the Twin Cities crinoid. P. spinuliferus, n. sp. may be separated from the Canadian form in several ways. The dorsal cup of P. spinuliferus is wider relative to its height, and P. priscus lacks the small nodes or spines on the pinnules that are characteristic of P. spinuliferus. The arms of P. priscus are heavier compared to size of the calyx. In ad- dition, the brachials of P. priscus are mature biserial whereas those of the Twin Cities species are immature biserial; however, this feature may be of ontogenetic rather than taxonomic significance because specimens of P. priscus commonly are larger than those of P. spinuliferus. P. billingsi Wachsmuth and Springer (1897, p. 277, pl. 21, figs. la, 1b) also from the Middle Ordovician of Canada differs from both P. priscus and P. spinuliferus, n. sp. in having four instead of two arms in each ray.

Diagnosis. — A species of Cupulocrinus characterized by a coni- cal dorsal cup with a narrow base, dorsal cup walls straight, dorsal cup plates smooth, sutures not deeply incised; arms moderately slender with several irregular isotomous branches; primibrachs four or more, secundibrachs numerous for Cupulocrinus; brachials with round backs, height/width moderate; stem round, proximal part of column tapering gently, columnals not strongly nodose. Description. — Dorsal cup conical with straight sides, base of cup narrow, height/width 0.9; dorsal cup plates smooth with slightly incised sutures. Five infrabasals, pentagonal, truncated at juncture with column, relatively large, about 30 percent of cup height; height/width averages 1.1. Basals five; lateral basals hexagonal, height/width 1.2; CD interray basal largest of basals, septagonal, distally trun- cated for reception of anal X, height/width about 1.5; basal circlet about 40 percent of cup height. Lateral radials four, pentagonal, height/width about 0.7, radials about 30 percent of cup height; radial facets slightly curved, wide, about 70 percent of total width of radial. Radianal pentagonal, located in primitive position below the C ray R, radianal equidimensional. Anal X not completely known, presumably hexagonal, slightly wider than radianal, located above CD interray basal and between C and D ray radials. C ray radial pentagonal, slightly smaller than other radials, height/width is 1.0. Fragment of anal sac preserved. Anal series plates in single vertical row, plates basically hexagonal, height/width 1.1; anal series doubly flanked by row of hexagonal plates; these roughly half as large as anal series plates. 428 BuLLETIN 304 Arms uniserial, nonpinnulate, branching isotomously, branches irregular; each half-ray branching two to four times. Brachials round-backed, smooth; sutures of typical cupulocrinoid type, primi- brachial sutures with gaping lip of moderate size; secundibrachs with small gape; tertibrachs and higher brachials without gape and with straight sutures; articular surfaces unknown. Number of brachials variable in all arm segments. Non-axillary brachials quadrangular; height/width as follows: primibrachs, 0.48; secundibrachs, 0.6; terti- brachs, 0.8; quartibrachs, 0.6; quintibrachs, 0.7; hexibrachs, 1.0. Axillary brachials pentagonal, height/width as follows: primaxil, 0.6; secundiaxil, 1.0. Arm branching formula irregular; variation in branching pattern increasing distally. At least five primibrachs. Branched secundibrachial series of six or seven plates. Tertibrachial series branched or unbranched, branched series with seven to nine plates; unbranched series of at least 20 plates. Quartibrachial series branched or unbranched, eight plates in branched series, up to 27 in unbranched series. Nine quintibrachs in only known branched series; single, incompletely preserved unbranched series with 15 plates. Hexibrachial series not fully known, at least nine plates present. Column incompletely known, round, with pentalobate axial canal occupying about one-third of stem diameter. Columnals not nodose, three orders of plates present; heights as follows: Order 1, 0.4 mm; Order 2, 0.15 mm; Order 3, 0.08 mm. Complete order formula: 1-3-2-3-1. Remarks. — C. gracilis (Hall) is represented in the Twin Cities fauna by four partial specimens and several arm fragments. Two specimens (UM 9292 and 9295) are dorsal cups. Although the number of primibrachs is uncertain, at least four or five plates must have been present in the A and E rays of UM 9295. The other speci- mens, UM 9293 and 9294, are detached sets of arms, and the dorsal cups are not known. The arms and the dorsal cups are considered conspecific for two reasons. First, the dorsal cups and arms were collected from the same bed at the same locality. Second, both the arms and dorsal cups are typical of cupulocrinids. Although C. gracilis was originally described by Hall (1847), the form was emended by Kolata (1975) who had examined the type material. The Twin Cities crinoids differ slightly from the Illinois specimens figured by Kolata (1975, pl. 7, figs. 6-8) in having MippLe OrpoviciAN CRrINoIDS: BROWER & VEINUS 429 brachials that are wider relative to their heights. This is attributed to age rather than taxonomy because the Twin Cities specimens are larger than those from Illinois; in most crinoids the width/height ratio of the brachials increases in older animals (e.g. Brower, 1974a, pp- 26-29). C. gracilis is easily separated from all other cupulocrinids by the nature of the stem, shape of the dorsal cup, ornamentation of the dorsal cup, shape of the arms, and the arm branching formula. In general, C. gracilis has fewer arm branches and more secundibrachs than most other species. As in other cupulocrinids (see discussion of C. jewetti), there is no significant correlation between the num- ber of secundibrachs and tertibrachs; based on nine observations, the correlation coefficient is only —0.16. In C. gracilis the dorsal cup plates are smooth and the sutures are not strongly depressed. The following species either have plates with rugose stellate ridges or swollen and nodose plates with de- pressed sutures: C. jewetti (E. Billings) (1859, p. 43, text-fig. 13; see Springer, 1911, p. 28, pl. 1, figs. 10-12; pl. 3, figs. 5-7), C. zewetts kentuckiensis Springer (1911, p. 32, pl. 3, figs. 8, 9), C. polydactylus (Shumard) (see Meek, 1873, p. 22, pl. 3bis, fig. 9), C. heterobracht- alis Ramsbottom (1961, p. 12, pl. 5, figs. 1-5), C. sepulchrum Rams- bottom (1961, p. 14, pl. 4, figs. 8, 9), C. angustatus (Meek and Worthen) (see Meek and Worthen, 1875, p. 492, pl. 23, fig. 8), and C. minimus Springer (1920, p. 88, pl. 75, figs. 6a, b). In addition, C. jewetti, C. jewetti kentuckiensis, C. polydactylus, and C. angusta- tus exhibit brachials that are much wider relative to their height. C. sepulchrum and C. heterobrachialis are also characterized by pentagonal columns which differ from the round stem of C. gracilis. The plates of C. erraticus (Miller) (1881, p. 316, pl. 8, figs. 1, Va) are smooth but the sutures are depressed, whereas C. gracilis pos- sesses smooth sutures. Like C. gracilis, C. conjugans (FE. Billings) (1857, p. 268; 1859, pp. 41, 44, pl. 3, figs. 8a, b; pl. 4, figs. 1, 2) and its synonym C. cylindricus (E. Billings) (see Springer, 1911, p. 37) shows smooth dorsal cup plates and sutures. C. conjugans has a dorsal cup that is wider relative to its height, the proximal part of the column tapers more rapidly, and the radial facets are much narrower. C. gracilis is most closely allied to C. humilis (E. Billings) 430 BuLwetin 304 (1857, \p: 270; see 1859, p.°39,: pl: 3, fig» 4; Springer, 191 iapa2es text-fig. 2, pl. 1, figs. 8, 9; pl. 3, figs. 1-4), C. latibrachiatus (E. Billings) (1857, p. 270; see 1859, p. 39, pl. 3, figs. 5a-c), C. drum- muckensis Kolata (1975, p. 38; see Ramsbottom, 1961, p. 13, pl. 5, figs. 6, 7), and C. heterocostalis (Hall) (1847, p. 85; pl. 28, figs. 3d, e, possibly figs. 3c, f; not figs. 3a, b; see Springer, 1911, p. 30, text- fig. 3). C. heterocostalis exhibits a wider cup with basals that are shorter compared to the overall size of the cup. Also the primi- brachial series is more slender than in the Twin Cities form. C. humilis and C. latibrachiatus are closely related. Both species are characterized by relatively wider dorsal cups with rounded walls that contrast with the straight-walled and more slender cup of C. gracilis. Also the brachials of C. gracilis are more slender relative to their height. C. drummuckensis possesses slender arms with equi- dimensional brachials (height equals the width) compared to the heavier arms with relatively wider brachials of C. gracilis.

Description of adult.— Dorsal cup broadly conical with rounded walls, height/width about 0.7; ornamentation variable, typically with more or less well-defined stellate ridges; stellate ridges of some specimens covered with four or five smaller ridges made up of fine nodes, plate surfaces granular. Infrabasals five, pentagonal, height/width approximately 0.9; infrabasals about 33 percent of cup height. Basals five, lateral inter- ray basals hexagonal, height/width roughly 1.0; CD interray basal septagonal, distally truncated for anal X; basal circlet about 50 per- cent of the cup height. Radials pentagonal; height/width of lateral radials averaging 0.6; C ray radial slightly smaller than lateral radials, height/width 0.5; radial circlet less than one-third of dorsal cup height. Radianal pentagonal, height/width about 1.0, radianal in primitive position below C ray radial. Anal X hexagonal, height/ width 1.0, above CD interray basal and between radials of C and D rays. Radial facets occupying entire width of radials; articular surface crescent-shaped with narrow dorsal ligament pit, pit separated by longitudinal ridge from ventral ligament pit. Anal sac only partly known, of typical cupulocrinoid type, con- sisting of central range of large hexagonal anal series plates flanked by much smaller plates. Anal series plates with median-ray ridge, height/width roughly 1.0. Facet on proximal part of first anal series plate, with one central and two flanking ligament pits separated by shallow ridges. Arms uniserial, nonpinnulate, branching isotomously at about four levels. Brachials with round backs. Proximal brachials often nodose, distal brachials with smoother outlines; surfaces of proximal brachials commonly covered with small nodes or granules, distal brachials granulose or smooth. Non-axillary brachials rectangular, with following height/width ratios: primibrachs, 0.2; secundibrachs, 0.4; tertibrachs, 0.6; quartibrachs, 0.7; quintibrachs, 1.0; hexibrachs, 1.1. Axillaries pentagonal, height/width ratios: primaxil, 0.3; secun- diaxil, 0.3; tertiaxil, 0.5; quartiaxil, 0.8; quintiaxil, 1.0. Variation of arm branching structure discussed under Remarks. 432 BuLuetTin 304 Column known only in young specimen, round, with penta- lobate axial canal, tapering distally. Several orders of plates present, most nodose, some with straight sides. Attachment device probably a small lobate or digitate holdfast that was cemented to a bryozoan. Remarks. — About seven well-preserved crowns from the Twin Cities and a number of partial crowns, cups and arm fragments are definitely placed in this species. Six specimens, UM 5942, occur on a single slab of granular Platteville Limestone (Carimona Member) from an unspecified locality in Fillmore County. Three crowns and one arm fragment, UM 9278, 9279 and 9282, were collected at the Twin Cities Brick Plant in St. Paul from Bed 5 of the Decorah Shale. The last crown, UM 9283, is a juvenile with a complete stem from Bed 4 of the Decorah Shale. The stem was probably attached to a large ramose bryozoan. The attachment device is buried underneath the bryozoan but probably was a small lobate or digitate holdfast that was cemented to the surface of the bryozoan. The orientation of the attachment device indicates that bryozoan was probably erect when the crinoid was alive. The entire crinoid is about 45 mm long. All of the other specimens from Bed 5 and from the Platteville are associated with large ramose bryozoans and these individuals could have been attached to bryozoans like the Bed 4 specimen. Comparison of UM 9283 and 9278 illustrates some ontogenetic changes. The calyx widths of the two specimens equal about 8.0 and 15 mm. The most striking change with growth is a decrease in the height/width ratios of the calyx plates and brachials. This shows that the width of these plates was growing more rapidly than the height. Several of the Twin Cities specimens preserve the articular surfaces of the radials and brachials. On the primibrachs, the cen- tral parts of the sutures are depressed which denotes a strong “patelloid” process. Proceeding distally, the “patelloid” processes become progressively less prominent and the sutures between the quartibrachs and quintibrachs are straight or almost so. The distal articulating surface of fully preserved primibrachs and _ secundi- brachs has an outer lip or rim which encloses a longitudinal trough or dorsal ligament pit with its long axis parallel to the width of the brachials. When the rim is weathered or broken, a crescent-shaped depression appears; this represents the dorsal ligament pit. In several Mippie OrpoviciaAn Crinoips: BROWER & VEINUS 433 tertibrachs, the rim is replaced with small supplementary plates; during the life of the crinoid these were probably joined by an in- tegument to form a more or less rigid pavement. The ventral liga- ment pits are poorly defined, only being known in a few tertibrachs. These ligament pits are represented by vague depressions flanking the food grooves, and they grade into the dorsal ligament pits along the margins of the brachials. The food grooves of the brachials are visible in UM 9278 where the sides of several distal series of brachials are exposed, disclosing four longitudinal rows of small plates. The two central rows of smaller plates are lappets, which are set at an angle to the two outer rows of the larger side-covering plates. There is one lappet to each covering plate, and four-and-one-half pairs of covering plates to each brachial. Every fifth covering plate is shared by two continguous brachials. The lateral walls of the brachials are somewhat raised above the level of the covering plates. Assuming that the tube foot arrangement of C. jewetti is the same as in the Recent Antedon (Nichols, 1960, p. 107), each lappet would have been associated with three food-catching tube feet. The variation in ornamentation in the Twin Cities specimens exceeds that known in crinoids from Kirkfield, Ontario (Springer, 1911, p. 28, pl. 1, figs. 10-12; pl. 3, figs. 5-7). The typical Kirkfield individuals possess vaguely defined single stellate ridges on the dorsal cup. The primibrachs and secundibrachs are nodose or swol- len, but distally the brachials gradually become smooth with shelf- like projections on their lateral margins. The dorsal cup ornamenta- tion of the Twin Cities material ranges between two extremes. First are crinoids that resemble typical Kirkfield animals such as UM 5942. The other extreme includes specimens like UM 9278; this calyx shows vague single stellate ridges, but a series of about four fine nodose ridges is superimposed on the stellate ridges. All speci- mens can be arranged into the following gradational sequence: UM 5942, 9279, probably 9281, 9283, 9282, and 9278. Some of the primi- brachs and secundibrachs of the Twin Cities individuals are nodose, as in the Kirkfield material, e.g., UM 5942, 9278, 9282; in several, the nodose or swollen brachials exhibit a row of small distal nodes. The nodose primibrachs and secundibrachs grade into smooth plates in UM 9283 and 9279. The distal brachials of the Twin Cities crin- 434 BuLcetTin 304 oids are sometimes nodose with small nodes covering the surface, e.g., UM 9278. Other brachials are simply nodose, but most of the distal brachials bear smooth surfaces and margins, e.g., UM 9283, 5492. The shelf-like projections found in the typical Kirkfield speci- mens are conspicuously absent. However some Kirkfield examples possess smooth-sided brachials like the Twin Cities forms. This dis- cussion shows that the Twin Cities specimens have ornamentation which differs somewhat from that of typical Kuirkfield crinoids. Nevertheless, the ornamentation of the two groups of animals over- laps and the specimens are considered conspecific with no doubt. C. jewettt is somewhat similar to a series of cupulocrinids with calyx plates bearing either or both nodose and stellate ridge orna- mentation. These species are C. jewetti kentuckiensis Springer (1911, p- 32, pl. 3, figs. 5-7), C. polydactylus (Shumard) (see Meek, 1873, p- 22, pl. 3bis, fig. 9), C. heterobrachtalis Ramsbottom (1961, p. 12, pl. 5, figs. 1-5), C. sepulchrum Ramsbottom (1961, p. 14, pl. 4, figs. 8, 9), C. angustatus (Meek and Worthen) (see Meek & Worthen, 1875, p. 492, pl. 23, fig. 8) and C. minimus Springer (1920, p. 88, pl. 75, figs. 6a, b). As implied above, populations of C. jewetti show some variation of ornamentation. For example, the Kirkfield specimens have plates that vary from nodose to stellate (Springer, 1911, pl. 1, figs. 10-12; pl. 3, figs. 5-7). However, some individuals in every local population that we have seen exhibit definite stellate ridges. Thus C. jewetti dif- fers from the other taxa in having more pronounced stellate ridges (in some crinoids), a more widely expanding dorsal cup and gen- erally stouter arms. The variability in arm branching pattern is tabulated below. Series Average number Range Coefficient of | Number of of plates variation specimens Primibrachs 3.4 3-5 20% 22 Secundibrachs 4.0 3-7 24% 22 Tertibrachs 7A 4-17 38% 30 Quartibrachs 9.6 6-20 48% 13 Quintibrachs 10.1 8-13 19% 9 There are two main patterns. First, the average number of plates in the different series increases distally. Second, with the ex- ception of the quintibrachs, the coefficient of variation [(standard deviation/mean) > 100] is augmented distally. The correlation Ui MippLe OrpovicIAN CrINOIDS: BROWER & VEINUS 43 coefficients between the number of plates in adjacent series are listed below. Series Correlation Degrees of Critical value coefficient (7) freedom of r at 0.05 probability level Primibrachs vs. secundibrachs 0.048 20 0.42 Secundibrachs vs. tertibrachs 0.024 28 0.36 Tertibrachs vs. quartibrachs -0.025 11 0.55 Quartibrachs vs. quintibrachs —0.550 7 0.67 The critical correlation coefficients are values that significantly exceed zero correlation. If the magnitude of the observed correla- tion exceeds the critical value, the observed correlation was drawn from a population with a correlation that is greater or less than zero. Comparing the observed correlations with the critical figures at the 0.05 probability level indicates that the number of plates in the adjacent brachial series are not significantly correlated, and these characters are believed to be independent of one another with respect to the genetic programming of the crinoid. The distribution of height and width of the brachials was in- vestigated within the arms of several specimens, especially UM 9278 (Pl. 14, fig. 3). Each arm series branches isotomously four or five times. The most striking patterns are as follows. 1. Both height and width decline distally but width decreases more rapidly. These differences were analyzed statistically. Graphs were plotted for Order of brachial (X) vs. width of axillary or non- axillary brachial (Y) (Text-figs. 7B, C, E, F). Simple power func- tions or allometric equations were fitted to the data and the dif- ferences between the slopes or exponents were tested statistically by Student’s t. In all cases, the slopes for non-axillary brachials have greater negative values than those of axillary brachials, subject to the 0.05 risk level. This indicates that the width of the axillary brachials decreases more slowly than the non-axillary brachials. 2. For any one order of brachials e.g., primibrachs or secundi- brachs, the axillaries are Jarger than the non-axillary brachials. The primaxils and primibrachs are characterized by nearly the same width but the axillary is higher (Text-figs. 7A, D).

This is related to the shape of the axil- laries. The secundiaxils and higher axillaries are spear-shaped be- cause the lateral margins expand distally so that the distal width exceeds the proximal width. The lateral margins of the primaxil are almost parallel and the two widths are equal. Comparison of axillary and non-axillary brachials was also done statistically. Simple power functions were calculated for both types of plates and the slopes and intercepts of the lines were compared with Student’s ¢ tests. Explanations of these statistics are available in Simpson, Roe, and Lewontin (1960, pp. 213-257, 373-420), Sokal and Rohlf (1969, pp. 404-548), and Imbrie (1956). In all cases, the initial intercepts of the lines for axillary brachials are significantly greater than those of non-axillary brachials at the 0.01 significance level. Thus axillary brachials are significantly higher than non-axillary plates with the same widths. The slopes for axillary and non-axillary brachials may or may not differ (compare Text-figs. 7A and 7D). 3. One could design an “idealized” crinoid with isotomously branching arms where the width of the brachials decreased 50 per- cent each time the arms branched. Beginning with primibrachial widths of 4.5 mm, this would yield widths of: primibrachs, 4.5 mm; secundibrachs, 2.25 mm; tertibrachs, 1.12 mm; quartibrachs, 0.56 mm; quintibrachs, 0.28 mm; hexibrachs, 0.14 mm (Text-figs. 7G). The widths of the successively higher arms branches would decline rapidly. This would, in turn, severely limit the number of arm branchings because the branches would quickly become too fragile to withstand current agitation; also, the food grooves might not be wide enough to function effectively. In C. jewetti from the Twin Cities, the decline of width is much less rapid than in the “idealized” model (compare Text-figs. 7B, C, E, F, with 7G). We also measured these differences statistically. The slope of the line for the “ideal” crinoid was treated as a hypothetical population parameter which was tested against the observed slopes for both axillary and non- axillary brachials. For all tested equations of Order of brachials (X) us. width of brachials (Y), the hypothetical slope has a larger nega- tive value than that of the observed slope at the 0.01 risk level. The conclusion drawn is that the widths of the brachials of the ob- served crinoids decrease less rapidly in the distal direction than those of the “ideal” crinoid. Consequently each arm series in the Twin MippLe OrpoviciIaAN CRrINoIDS: BROWER & VEINUS 439 Cities crinoid was able to branch four or five times; in an equivalent idealized crinoid, the arms would only branch about three times be- fore the terminal width was attained. The contrast between the pat- terns of C. jewetti and the ideal case is partially due to the shape of the axillaries because these spear-shaped plates expand distally. Also the brachial above the axillaries expands distally (see Text-figs. 7H, I, J which schematically illustrate the possible configurations; compare with PI. 14, fig. 3). 4. In C. jewetti, some arm series branch four times but others branch five times. Comparing the two types shows that the non- axillary quartibrachs and quintibrachs are wider in the arms that branched most often (compare Text-figs. 7A, C with 7D, F). This holds true for the axillary width but to a lesser extent (Text-figs. 7B, C). Although few data are available, the tentative conclusion is that wider brachial series branch more frequently than narrower ones. The contrasts between the slopes for the equations of the brachial series that branches four times vs. the one that bifurcates five times were also ascertained by Student’s t. These differ at the 0.01 significance level. For Order of brachials (X) vs. width of non- axillary brachials (Y), the slope for the series with five branches ex- hibits a smaller negative value that that with only four branches. In the case of Width (X) vs. height of non-axillary brachials (Y), the positive slope is larger for the more extensively branched arms. The statistics support the previous suggestion that the wider brachial series branch more often and possess more branches than narrower ones. However more data are required before this hypothesis can be fully confirmed. The wider brachial series were produced by larger width growth vectors for the brachials relative to overall size of the crinoid, given initially-formed brachials of about the same size and shape; although this cannot be shown for C. zewetti, this model is reasonable based on knowledge of the ontogeny of living and fossil crinoids (Brower, 1974a). This suggests that the genetic program- ming of arm branching is dictated by the same genetic package that programs the development of width. Note that these conclusions are tentative because they are based on a small number of specimens of only a few species. Further work on more specimens from many species is required before a definitive hypothesis can be formulated. We have also found it useful to characterize the arm branching 440 BuLLeTIn 304 patterns of crinoids in terms of network parameters (see Haggett and Chorley, 1974, pp. 1-105 for summary). As in streams and road patterns, the arms of crinoids may be visualized as networks. Streams serve to carry water and sediment; transportation networks are used for transfer of people and materials. The arms or networks of crinoids mainly function in trapping food and conveying the ac- cepted food particles to the mouth; also the gonads are located on the arms and the arms perform some respiration. Strictly speaking the arms of crinoids comprise minimally connected planar graphs in which a single distal node is only linked to one proximal node. The nodes or vertices represent the tips of the arms or the points where the arms branch. The edges or links between the adjacent nodes are formed by the brachial series. Taking the D ray arm of UM 9278 as an example, there are 26 nodes and 25 edges. This ray can be classified as an Order 4 “stream” (Strahler type) with an average bifurcation ratio of 2.39. The relatively low bifurcation ratio reflects the repeated isotomous branchings and regular bush-like pat- tern of the arms of C. jewetti; for comparison, an infinite topo- logically random channel network, similar to random walk graphs, theoretically produces a bifurcation ratio of 4.0. For the D ray of C. jewetti, the Cyclomatic number (V-E-G) equals zero. In the formula, V denotes the number of nodes on the graph, E refers to the number of edges, and G is the number of sub- graphs. The Beta index (E/V) is 0.96 whereas the Alpha index [ (Cyclomatic number / (2V-5)) times 100)] is nil. The low values of Cyclomatic number, Alpha index and Beta index show that the arms of C. jewetti constitute a simple network. The arm branching patterns of other crinoids are being investigated in the same fashion. If the arms are completely preserved, other parameters that are analogous to the drainage density and stream frequency of physical geography can also provide useful information.

Pl. 15; figs, 1-3,-5:.6; Pl 1G. fies oa Diagnosis.— A species of Cupulocrinus with characteristic longitudinally grooved or scalloped stem; distal portions of arms branching heterotomously; dorsal cup conical, with smooth plates. Description. — Dorsal cup conical with straight walls, height/ width about 1.0; dorsal cup plates smooth, with slightly incised sutures. Infrabasals five, pentagonal, height/width roughly 0.9; infra- basal circlet less than one-third dorsal cup height. Basals five; lateral interray basals six-sided, height/width averaging 1.1; CD interray basal larger than lateral interray basals, septagonal, distally truncated for anal X; basal circlet almost half cup height. Lateral radials four, pentagonal, height/width 0.8; radial circlet 33 percent of cup height. Radial facets occupying entire plate width; facets otherwise unknown. Radianal pentagonal, in primitive position be- low C ray radial, pentagonal, height/width 0.9. Anal X large, hexa- gonal, located above CD interray basal and between C and D ray radials. C ray radial, pentagonal, smaller than other radials, height/ width 0.6. Anal sac not known. Arms uniserial; branching pattern isotomous up to secundi- brachs or tertibrachs, higher branches heterotomous, arms broad with round backs. Brachials smooth; unweathered sutures between ad- jacent brachials straight; some weathered sutures with small gape indicating presence of patelloid process; some brachials with distal lips on dorsal surfaces. Non-axillary brachials quadrangular, with following height/width ratios: primibrachs, 0.3; secundibrachs, 0.46; tertibrachs, 0.55; quartibrachs, 0.58; quintibrachs, 0.81; hexibrachs, 1.0; and septibrachs, 1.1. Axillaries pentagonal, height/width ratios: primaxil, 0.3; secundaxil, 0.55; tertiaxil, 0.87; quartaxil, 0.68; quinti- axil 0.90; hexiaxil, 0.85. Number of brachials variable. Primibrachs from four to five; five to seven secundibrachs present; branched tertibrachial series with four to six plates; higher branched series with four or five plates. Column not completely known, basically round with numerous longitudinal grooves or scallops on each columnal; scallops less 442 BuLuetTin 304 prominent distally. Axial canal pentalobate. Proximal part of stem with two orders of columnals; orders 1 and 2 0.20 and 0.15 mm high, respectively; orders alternating in proximal part of column, columnals with crenulate sutures. Remarks. — This species is founded on seven crinoids which consist of whole or partial crowns with or without attached stem segments. Several of the specimens, the holotype UM 9286 and a paratype UM 9280, are complete crowns so that variation in arm structure can be studied in detail. Portions of the stem are attached to several of the crowns, such as paratype UM 9285. The number of primibrachs ranges from four to five plates with a mean of 4.6 and a coefficient of variation of 11.2 percent. Slightly more variation is observed in the secundibrachs which have a coef- ficient of variation of 12.8 percent. The mean equals 5.5 plates and from five to seven plates may be present. The variation of height and width for the brachials in C. canaliculatus, n. sp. is essentially the same as in C. jewettt. The network statistics were determined for a heterotomous arm of C. canaliculatus, n. sp. which has seven levels of branching. Some of the values are either identical or nearly the same as those of the isotomous arms of C. jewetti. The Cyclomatic number and Alpha index are both zero, and the Beta index is 0.93 (vs. 0.96 in C. jewetti). However, the arms of C. jewetti form a fourth order Strahler “stream”, but C. canaliculatus, n. sp. only reaches the third order. The average bifurcation ratios of C. jewetti and C. canalicu- latus, n. sp. equal 2.39 and 4.5, respectively. The contrasts in bifur- cation ratios and “stream” orders between the two crinoids are caused by the differences in arm branching, C. jewetti being isoto- mous with a moderate number of branches whereas C. canaliculatus, n. sp. is characterized by more extensive heterotomous branching. C. canaliculatus, n. sp. is related to many cupulocrinids with smooth plates. These forms are C. conjugans (E. Billings) (see 1859, pp. 41, 44, pl. 3, figs. 8a, b; pl. 4, figs. 1, 2), C. humilis, (E. Billings) (see Springer, 1911, p. 28, text-fig. 2, pl. 1, figs. 8, 9; pl. 3, figs. 1-4), C. drummuckensis Kolata (1975, p. 38; see Ramsbottom, 1961, p. 13, pl. 5, figs. 6, 7 under C. gracilis Ramsbottom), C. hetero- costalis (Hall) (1847, p. 85, pl. 28, figs. 3d, e, possibly figs. 3c, f, not figs. 3a, b; see Springer, 1911, p. 30, text-fig. 3), C. gracilis Mipp_e OrpoviciaN CrINoIDs: BROWER & VEINUS 443 (Hall) (see Kolata, 1975, p. 37, pl. 7, figs. 6-8), C. molandert Kolata (1975, p. 39, pl. 8, figs. 6, 7, text-fig. 11), C. plattevillensis Kolata (1975, p. 39, pl. 7, figs. 1-3, 9), and C. latibrachiatus (E. Billings) (see 1859, p. 39, pl. 3, figs. 5a-c; see also C. cf. latibrachiatus Kolata, 1976, p. 450, pl. 1, figs. 1-5). C. canaliculatus may be separated from these taxa by the characteristic grooved column, the heterotomous arms, and shape of the dorsal cup. C. sepulchrum Ramsbottom (1961, p. 14, pl. 4, figs. 8, 9) and C. heterobrachialis Ramsbottom (1961, p. 12, pl. 5, figs. 1-5) also exhibit heterotomous branching but these British forms differ in possessing deeply incised plate sutures and in lacking the charac- teristic column of C. canaliculatus n. sp. The dorsal cup plates of C. canaliculatus are smooth and the sutures are not markedly incised. These plates are easily separated from the either or both stellate and nodose plates with depressed sutures seen in C. jewetti (E. Billings) [g.v.], C. jewetti kentucki- ensis Springer (1911, p. 32, pl. 3, figs. 8, 9), C. polydactylus (Shu- mard) (see Meek, 1873, p. 22, pl. 3bis, fig. 9), C. angustatus (Meek and Worthen) (see Meek & Worthen, 1875, p. 492, pl. 23, fig. 8), and C. minimus Springer (1920, p. 88, pl. 75, figs. 6a, b).

America, Mem. 137, p. 143. 444 BuLLeTIN 304 Diagnosis.— A species of Grenprisia characterized by stellate plates in the anal sac; margins of brachials angular and sharp. Description of adult.— Dorsal cup conical with moderately wide base, sides straight, expanding distally, height/width about 0.67; dorsal cup plates smooth with depressed sutures. Infrabasals five, roughly pentagonal with slightly curved proxi- mal margins fitting into the proximal pentameres of the stem, height/width 0.8. Lateral basals four, hexagonal, usually slightly wider than high, height/width 0.8. CD interray basal largest in dorsal cup, septagonal, distally truncated for reception of anal X. Lateral radials four, generally pentagonal, height/width about 0.7; radial facets almost as wide as radials; nature of facets not seen. Small interbrachials in lateral interrays; interbrachial 7 hexagonal, largest interbrachial; about five irregular second and third inter- brachials, two or three plates in each range; all interbrachials located at level of primibrach /. CD interray much wider than lateral inter- rays. Radianal pentagonal, in primitive position below C ray radial and obliquely above CD and BC interray basals, height/width 0.8. C ray radial roughly hexagonal, located above radianal, height/width approximately 0.7. Anal X smaller than other CD interray plates, septagonal, lying above CD interray basal and between radianal, C and D ray radials, height/width 0.96. Anal sac partially preserved, large, high, not balloon-shaped; proximal two or three ranges of plates smooth with depressed sutures; these grading distally into plates with sharp stellate ridges. Proximal plates large and regular; plates smaller distally. Distal plates in anal sac in vertical rows; relatively little intercalation of new plates. Proximal plates in the anal sac mostly “axillaries”; new vertical rows of plates intercalated into anal sac above these “axil- laries”; most intercalation of new plates probably confined to proxi- mal five or so ranges of anal sac plates. Arms incompletely known in adult specimen. Four primibrachs in all known rays with primibrach 4 axillary. Non-axillary primi- brachs uniserial, wider than high; height/width from roughly 0.6 to 0.8; sides of brachials angular, with spinose and shelf-like projec- tions; these interlocking arms in closed position. Primaxil penta- gonal, height/width 0.65, branching isotomously. Higher brachials not known in mature specimen; in smallest crinoid, seven secundi- brachs in each half-ray with the last plate axillary; secundibrach 7 MippLe OrpoviciAN Crinoips: BROWER & VEINUS 445 giving rise to poorly known heterotomous branches. Proximal portion of column pentagonal with large pentagonal axial canal occupying most of the column, all sutures crenulate. All columnals nodose, but thinner plates less nodose than thicker ones; columnals divided into five pentameres; sutures oriented radially, lying in depressed part of column; small pores at the suture between pentameres of adjacent columnals in one specimen. Three columnal orders present, with the following heights: Order 1, 0.4 mm; Order 2, 0.2 to 0.3 mm; Order 3 averaging 0.17 mm. Complete order formula: 1-3-2-3-1. Fourth order perhaps present in distal part of column in largest crinoid. Remarks. — Three crinoids from the Twin Cities are referred to G. billingst. One specimen, UM 9268 is an adult calyx with part of the stem and most of the anal sac preserved. The second animal, UM 9269, consists of a submature dorsal cup with a portion of the column attached. The only known crown is the smallest specimen, UM 9271. The Twin Cities specimens differ from the Kirkfield examples described by Springer in slight details of the arm branching. Kirk- field crinoids show either three or four primibrachs in each ray; the mean equals 3.5 plates with a coefficient of variation of 15 percent. All six rays that could be tabulated for the Twin Cities material bear four primibrachs. Student’s ¢ tests indicate that the 99 percent confidence level for the Kirkfield specimens ranges from 2.7 to 4.3 plates, which includes the 4.0 figure for the Twin Cities crinoids. Consequently the difference is not considered statistically significant, and it is concluded that both the Kirkfield and Twin Cities speci- mens belong to the same interbreeding or potentially interbreeding population. The number of secundibrachs in the nine half-rays that could be tabulated for the Canadian specimens ranges from three to ten plates with an average of 6.2 plates; the coefficient of variation constitutes 40 percent. As in the cupulocrinoids discussed above, the variability in arm branching increases distally. The number of secundibrachs could only be counted in two half-rays of the smallest crinoid from the Twin Cities, both of which exhibit seven plates. All three specimens from the Twin Cities disclose the penta- meres of the column. However, the pores between the adjacent pentameres and adjacent columnals are only clearly visible on UM 9269. 446 BuLLetin 304 G. billingsi is easily separated from G. springeri Moore (1962b, p- 38; see illustrations in Springer, 1911, p. 37, pl. 4, figs. 5-7, where the species is listed as Ottawacrinus typus W. R. Billings) by the nature of the anal sac. G. springert has smooth plates but those of G. billingst have sharp stellate ridges. In addition, the brachial margins of G. billingst are much more angular than in the other species. Figured specimens. — UM 9258, 9269, and 9271; the latter specimen is in the collection of D.

Posterior area of tegmen partially preserved in a crushed crown; about six ranges of plates above anal X; area for anal opening large, elliptical with long axis vertical; anal area above third range of plates. 448 BuLueTIn 304 Arms uniserial, non-pinnulate, cup large relative to size of arms, arms branching isotomously and heterotomously. Depth of brachials exceeding width, depth/width approximately 1.5; food grooves deep with U-shaped plan-view; face of brachial with scar showing trace of movement of axial canal during brachial growth; brachials with- out transverse ridges; ligament pits gently concave, not strongly differentiated. Arm branching formula as follows: Two or three primibrachs, these branching isotomously. Secundibrachs four or five; arms branching isotomously. Outer arms borne by unbranched secundibrachs, or branching once on one of the tertibrachs. Inner arms on secundibrachs branching heterotomously four times in the only known complete ray; about six to nine plates in each branched series. Non-axillary branchials with rectangular outlines; height/ width ratios: primibrachs, 0.42; secundibrachs, 0.47; tertibrachs, 0.57; quartibrachs, 0.71; quintibrachs, 0.68; hexibrachs, 0.75.

Column only known from columnals; stem diameter small; columnals either round or obscurely pentagonal with pentalobate axial canal. Remarks. — The complex nomenclature of C. dicyclicus (Sarde- son) is reviewed under “Statistical studies of Twin Cities carabo- crinids.” The available material includes several poorly preserved crowns, roughly five dorsal cups and fragments thereof, a series of “model cups” constructed by Sardeson from loose plates, numerous isolated calyx plates and some brachials, and about 10 holdfasts. C. dicyclicus (Sardeson) is similar to C. magnificus Sardeson which is also found in the Decorah Shale of Minnesota. Comparison of these two forms is discussed in the statistical section on Twin Cities carabocrinids and under C. magnificus. Virtually all species of Carabocrinus are characterized by stel- late ridge ornament which differs from the more complex ornamen- tation of C. dicyclicus (Sardeson). In the latter species, the basic ornamentation consists of nodes with or without stellate ridges. Also, the approximately hemispherical cup of C. dicyclicus (Sardeson) is not the same as that of most other carabocrinids. The poorly known C.? tuberculatus E. Billings (1859, p. 33, pl. 10, figs. 2a-c) also has the plates covered with nodes but these are Muppte OrpoviciAN CRINOIDS: BROWER & VEINUS 449 heavier than the nodes of C. dicyclicus (Sardeson). The dorsal cup of C.? tuberculatus is more conical and the arms are larger in proportion to the cup than in C. dicyclicus (Sardeson). C. ovalis Miller and Gurley (1894, p. 25, pl. 2, figs. 20, 21) possesses smooth plates that contrast with the ornamented plates of C. dicyclicus (Sardeson). Primary types. — The type specimens of Strophocrinus dicycl- cus Sardeson become those of Carabocrinus dicyclicus (Sardeson). Sardeson considered the dorsal cup with the extra anal plates, UM 9187, as the holotype of his Strophocrinus dicyclicus. The other ma- terial discussed in his 1899 paper was treated as paratypes of S. dicyclicus (UM 9188 - 9199).

Goniospires absent or weakly developed. Ornamentation of large and heavy stellate ridges; plates otherwise smooth. Description of adult.— Dorsal cup broadly conical with rounded walls; outline of cup resembling half an ellipse; maximum width at distal margins; height/width of average cup equals 1.03. Dorsal cup plate ornament of variable number of stellate ridges; basals with from five to 22 ridges, plates otherwise smooth. Structure of dorsal cup like that of C. dicyclicus (Sardeson) except for different shapes of plates. Height/width ratios of average plates: infrabasals, 1.26; basals, 1.28; radials, 0.81; inferradials, 1.08; superradials, 0.917; anal X, 1.1. Arms, column, and holdfast unknown. Remarks. —Sardeson described C. magnificus from several hundred isolated plates from the Decorah of Cannon Falls and St. Paul, Minnesota and Ellsworth, Wisconsin (see discussion above for history of nomenclature). Plates are common at the Cannon Falls locality but rare at the other two. Complete dorsal cups, crowns, columns, and holdfasts are unknown although Sardeson recon- structed cups from isolated plates. Sardeson did not formally desig- nate types, but obviously considered all well-preserved plates as cotypes or syntypes. Type nomenclature for isolated plates of echino- derms presents problems. We designate the “collection” of plates on the “model cup” of UM 9208 as lectotype; paralectotypes are UM 9209-9211, 9217-9221, and 9240-9243. C. magnificus is closely related to C. dicyclicus (Sardeson), also from the Decorah Shale of Minnesota as outlined under “Statistical Studies.” The two forms are easily distinguished by their ornamenta- tion. C. magnificus has a few large and heavy stellate ridges on plates that are otherwise smooth. C. dicyclicus exhibits plates with numer- ous nodes or pimples, either with or without stellate ridges. Also the height/width ratios of the plates and presumably the cups are larger in C. magnificus than in C. dicyclicus. C. magnificus is similar to various Middle Ordovician carabo- crinids from North America, especially C. vancortlandi E. Billings, (1859, p. 32, pl. 2, fig. 4) and C. huronensis Foerste (1924, p. 345, pl. 31, figs. 11, 13; see Sinclair, 1945, pl. 2, fig. 17). The cup of C. Mipp_e OrpoviciAN CrINOIDS: BROWER & VEINUS 451 magnificus is wider relative to its height and there are fewer and more prominent stellate ridges than in the other two crinoids. In addition, an egg-shaped cup is seen in C. vancortlandi in contrast to the half-elliptical outline of the Twin Cities taxon. C. geometricus Hudson (1905, p. 282, pl. 1, figs. 1, 2; text-fig. 7) and C. treadwelh Sinclair (1945, p. 715, pl. 2, figs. 14-16) have more conical cups with smaller height/width ratios, and more fine stellate ridges on those cups. The goniospires of C. treadwelli are much more promi- nent than those of C. magnificus, in which the goniospires are either lacking or poorly developed. The same type of ornamentation is found in C. slocomi Foerste, C. slocomi costatus Foerste (1924, pp. 350-353, pl. 31, figs. 1-10, pl. 32) and C. magnificus, but C. slocoms and its subspecies are characterized by elongate and angular dorsal cups in contrast to the wider and more elliptical cup of the Twin Cities crinoid. C. stellifer Brower and Veinus (1974, p. 61, pl. 2, figs. 7, 10) and C. oogyt Kolata (1975, p. 29, pl. 5, figs. 3, 7) are poorly known but the ornamentation of these taxa is similar to that of C. magnificus. However the dorsal cup of the Twin Cities crinoid is both larger and more elongate than in the other two taxa. Specimens of C. magnificus are easily separated from C. estho- nus Jaekel (1918, p. 50, fig. 38), C. radiatus E. Billings (see 1859, p. 31, pl. 2, figs. 3a-e), C.? tuberculatus E. Billings (1859, p. 33, pl. 10, figs. 2a-c), C. micropunctatus Brower and Veinus (1974, p. 64, pl. 2, figs. 8, 9), and C. ovalis Miller and Gurley (1894, p. 25, pl. 2, figs. 20, 21) by the ornamentation and shape of the plates and dorsal cup.

America, Mem. 137, p. 139: Diagnosis. — A species of Palaeocrinus characterized by conical dorsal cup with a few sharp stellate ridges, brachials sharp-backed with sharp spine-like projections along lateral margins, anal tube present, column pentagonal. Description. — Dorsal cup conical with straight sides and nar- row base, height/width about 0.66; dorsal cup plate ornament of single sharp stellate ridges; ridge width from 0.2 to 0.5 mm; some shorter supplementary ridges, parallel to main ridges, also present on basals and radials; interbrachial J ornamented with nodes. Infrabasals five, pentagonal, height/width 0.9. Basals five; CD and BC interray basals with seven sides, truncated for reception of radianal and anal X; other basals hexagonal; all basals roughly equidimensional, height/width 0.9. Lateral radials four, basically pentagonal with narrow horseshoe-shaped facets, height/width 0.8; radial facets not seen. Small hexagonal interbrachial J plates in lateral interrays, higher interbrachials not present. CD interray widest. Radianal quadrangular, lying obliquely between CD and BC interray basals, anal X, and C ray radial. Anal X large, hexa- gonal, between C and D ray radials and obliquely above radianal, height/width 0.9. Anal series of large hexagonal and stellate plates; anal sac not seen. Arms partially known, branching isotomously three times. Brachials uniserial, non-pinnulate, with sharp backs; sides of brachials with spiny shelf-like lateral margins; articular surfaces poorly preserved; food grooves, deep, V-shaped. Two or three primi- brachs; nonaxillary brachials with rectangular outlines, height/width about 0.38; axillary brachials pentagonal, height/width roughly 0.47. Three secundibrachs, height/width approximately 0.7. Tertibrachs, nN So Mrpp_Le OrpoviciIaAN CRINOIDS: BROWER & VEINUS 4 three to six, height/width 0.8. Several quartibrachs known, height/ width 0.9. Only proximal portion of column preserved, pentagonal; axial canal obscure, round or pentagonal; all sutures crenulate. Columnals nodose, two orders of plates probably present. Remarks. — This species is represented by four specimens. Only one, UM 9272, a partial crown with a short segment of the column attached, is well preserved. The other three specimens, UM 9273, consist of a badly weathered crown in matrix and two arm frag- ments. The Twin Cities specimens closely resemble the Ottawa crin- oids assigned to this species in most respects, including the dorsal cup shape, small number of sharp stellate ridges, pentagonal stem, and sharp-backed arms that branch isotomously. The Twin Cities animals differ in several minor features. Some of the single stellate ridges have one shorter ridge lying beside them. According to the descriptions and illustrations presented by E. Billings (1857, p. 269; 1859, p. 45, pl. 3, figs. 6a, b) and Wilson (1946, p. 40, pl. 6, figs. 1a, b), the Ottawa material only shows single stellate ridges. The Twin Cities specimens seem to have longer spinose projections on the sides of the brachials. The published descriptions indicate that the Ottawa crinoids bear three or four primibrachs whereas the Twin Cities specimens have only two or three primibrachs. However, most dicyclic inadunate crinoids show wide variation in both arm branch- ing formula and ornamentation, and the Ottawa and Twin Cities crinoids are considered conspecific. P. angulatus is most similar to P. pulchellus EF. Billings (1859, p. 46; see Wilson, 1946, p. 40, pl. 6, fig. 3) and P. rhombtferus E. Billings (1859, p. 45; see Wilson, 1946, p. 40, pl. 6, fig. 2). P. pulchel- lus has a round column and broader and less distinct stellate ridges in contrast to the pentagonal column and sharp stellate ridges of P. angulatus. P. rhombiferus is also characterized by broad stellate ridges; in addition, the arms are much more slender than those of P. angulatus. The type species of the genus, P. striatus EF. Billings (1859, p. 25, pl. 1, figs. 5a, b; best illustrated in Hudson, 1911, pp. 217-246, text-figs. 4-19, pls. 5-7), is characterized by numerous and ill-de- fined stellate ridges. An anal tube is present in P. angulatus but the anus of P. striatus is located on the tegmen surface. P. chapmani 454 . Butvetin 304 (E. Billings) (1858, p. 71) is probably a synonym of P. striatus (Hudson, 1911, pp. 244-246, text-fig. 20). Figured specimen. — UM 9272. Other material. — Three specimens catalogued under UM 9273.

Mem. 7, p. 28, pl. 4, figs. 1-3. Diagnosis. — A species of Porocrinus characterized by a rela- tively wide dorsal cup with moderately wide base; cup walls slightly rounded, expanding upward rapidly. Ornament of single sharp stel- late ridges; surface between ridges granular, punctate on distal sur- face of radials; minute punctae on brachials. Goniospire areas large, with rounded outlines, not strongly depressed; individual slits of goniospires long and slender. Stem rounded pentagonal, rapidly tapering. Arms relatively short. Description. — Dorsal cup conical with rounded sides expanding upward rapidly, base of cup moderately wide, height/width of cup about 0.80; dorsal cup plate ornament of single sharp stellate ridges; area between ridges granular, large punctae on distal surface of radials, minute punctae on brachials, plate sutures not depressed; goniospire areas rounded, moderately large, covering about half the plates; goniospire areas not strongly depressed; individual slits of goniospires fine, numerous; goniospire slits along single sutures in largest specimen distributed as follows: radial-radial, seven or eight; radial-basal, seven; basal-basal, six to eight; basal-infrabasal, seven or eight. MippLe OrpoviciAN CRINOIDS: BROWER & VEINUS 455 Infrabasals five, pentagonal, height/width 0.49. CD and BC in- terray basals largest plates on dorsal cup, septagonal, truncated for reception of radianal and anal X; other basals hexagonal; basals almost equidimensional, height/width about 0.97. Lateral radials four, pentagonal, height/width 0.81; radial facets narrow, horseshoe- shaped, inclined outward, with deep ambulacral groove. Radianal quadrangular, almost equidimensional, located between CD and BC interray basals, anal X, and C ray radial. Anal X larger than radianal, hexagonal, located between C and D ray radials and obliquely above radianal, height/width 1.1. C ray radial smaller than other radials, height/width 0.64, located between anal X and B ray radial. Arms partially known, unbranched, sharp-backed with brachials compressed laterally. About ten primibrachs preserved on B ray arm and seventeen on A ray arm. Brachials uniserial, nonpinnulate, height/width 0.7; brachials about 25 percent deeper than wide. Proximal part of column preserved, cross-section round or pentagonal with rounded margins; observed part of column tapering rapidly. Columnals much wider than high, characteristic scalloped and crenulate columnals seen in most species of Porocrinus; only one order of colmnals observed; columnals higher distally. Remarks. — Three Twin City specimens are placed in this species. The best, UM 9276, is a crown preserving part of the arms and stem. The two specimens in UM 9277 are a calyx with an at- tached stem segment and an isolated stem fragment. Species of Porocrinus are defined on the basis of calyx shape, ornamentation, nature of the goniospires, including number and thickness of the goniospire slits, their spacing and length, size and shape of the gonio- spire groups, and whether the goniospire groups are depressed or not, the shape of the column, and the length of the arms. Because of poor material and, in some, poor illustrations, not all of these characters can be evaluated for all species. However, Porocrinus pentagonius can be distinguished from the other described porocrinids as follows. It differs from P. conicus E. Billings (1857, p. 279; see 1859, p. 34, pl. 2, figs. 5a-d; Kesling and Paul, 1968, p. 26, text-figs. 11, 12, pl. 6, figs. 1-5; pl. 7, figs. 1-5) in having sharp stellate ridges, larger goniospires and a higher cup. P. shawi Schuchert (see Kesling and Paul, 1968, p. 31, text-fig. 14, pl. 456 BuLLeTin 304 4, figs. 1-4) has expanded stellate ridges and goniospires which are coarser than in P. pentagonius. The goniospires of P. crassus Meek and Worthen (see 1868, p. 330, pl. 4, figs. 2a, b, text-figs. a, b) and P. scoticus Ramsbottom (1961, p. 17, pl. 5, fig. 8) are deeply de- pressed. P. smithi Grant (1881, p. 42, unnumbered pl., figs. 1-8) is characterized by a more conical cup with deeply sunken and trilo- bate goniospires. The stem of P. smithi is round, which distinguishes it from the rounded-pentagonal column of P. pentagonius. The goniospires of P. pyramidatus Kesling and Paul (1968, p. 25, text- fig. 10, pl. 5, figs. 1-6; pl. 6, figs. 6, 7) are pyramid-shaped whereas those of P. fayettensis Slocum (1924, p. 333, pl. 29, figs. 14-22; pl. 30, fig. 14) are small and round. P. elegans Kesling and Paul (1968, p. 25, pl. 3, figs. 1-8; pl. 4, figs. 7-9) is also from the Decorah or Galena of South St. Paul. P. pentagonius is easily separated from P. elegans by its wider cup and larger goniospires. Figured specimen. — UM 9276. Other material. — Two specimens in UM 9277.

Billings) Pl. 16, fig. 4 Remarks.— This species is represented by a single specimen, UM 9274, which is a crown with a short stem segment. John M. Warn (1973, personal communication) kindly identified the crinoid. Warn and Strimple (1977) have recently completed a study on cincinnaticrinids, formerly termed heterocrinids and homocrinids. The morphology and nomenclatural problems of J. tenius are fully discussed in their monograph (Warn and Strimple, 1977, pp. 61-66, pl. 8, text-fig. 15). Fenton (1929a, p. 492, pl. 36, fig. 4) figured a juvenile cincin- naticrinid from the Black River (probably Platteville) of St. Paul. Inasmuch as features that are generically and specifically diagnostic Mipp_e OrpoviciAN CrINoIps: BROWER & VEINUS 457 in adults are not well developed in immature specimens, the identity of the crinoid is not certain (Warn, 1973, personal communication ) and it could belong to Heterocrinus, Isotomocrinus or some other genus.

Diagnosis. — A large species of Cremacrinus characterized by nodose dorsal cup plates; anal tube bearing strong median ridge; all plates with moderately coarse punctae; E ray arm long, slender and unbranched; B ray arm nearly as large as A and D ray arms; A, B and D ray arms having numerous branches with alternate brachials axillary; axil arms with knuckle-like enlargements at bases of axil- laries. Description. — Crown large with heavy arms. All calyx plates covered with moderately coarse punctae, diameters averaging about 0.15 mm in mature crinoid; dorsal cup plates nodose; axil arms with knuckle-like swellings where the ramules are given off. Basal series triangular, of four plates; stem facet shared by all plates. 458 BuLuetTin 304 E ray inferradial rectangular, height/width about 1.5; super- radial almost rectangular, height/width about 0.8. E ray arm un- branched, composed of uniserial and nonpinnulate brachials; height/ width averaging about 1.4. A and D ray radials undivided, largest plates in dorsal cup. Two main axil series, each commonly consisting of two plates; one or three plates rare. Non-axillary plates quadrangular with height/width approxi- mately 0.4; axillaries pentagonal, height/width about 0.8. Axil arms branching in typical cremacrinid pattern; arms commonly branching on alternate plates; first or third plate axillary in some specimens; axil arms of large crinoids branching from 12 to 15 times. Axil arms strongly geniculate, with knuckle-like swellings at branchings; axil- laries pentagonal, swollen distally, height/weight of proximal plates about 0.8, distal plates approximately equidimensional; non-axillaries with trapezoidal outline becoming more narrow distally, height/ width about 0.7. Articular surfaces of brachials not observed; many sutures between distal surface of non-axillary brachials and proxi- mal surfaces of axillary brachials partially fused in the proximal parts of the axil arms; such sutures showing no traces of fusion in the distal parts of the arms. Ramules long, slender, consisting of elongate plates with height/width about 1.6 to 2.0. B and C rays compound. Inferradials small, triangular, height/ width nearly 1.0; B and C ray inferradials not in lateral contact. B ray superradial large, height/width about 1.0. B ray axil arm exactly as in A and D rays. C ray superradial slightly smaller than B ray radial, equidimensional, distally bearing anal X. Height/width of anal X is 1.0; anal X nearly as large as C ray radial. Anal tube, large, straight, consisting of nodose plates with median ridge. Column not completely known; proximal parts consists of nodose columnals, height/width of columnals about 0.35. Distal portion of stem and attachment device not seen. Remarks. — C. arctus is known from about 50 specimens, most of which are dorsal cups with short fragments of the arms attached. Some of the crinoids represent crowns which were buried in a com- pressed version of the living orientation. When describing C. arctus, Sardeson did not formally designate type specimens. Reading Sar- MippLE OrpDovICIAN CRINOIDS: BROWER & VEINUS 459 deson’s paper makes it obvious that he considered most of his well- preserved specimens as syntypes. In order to stabilize the types of C. arctus, we designate UM 9306 as lectotype and UM 9300-9305, UM 9307-9318, and NMNH (S) 2181 as paralectotypes. Sardeson figured the specimens on his Plate 11 as follows: UM 9305, figs. 1, 2; UM 9308, figs. 3, 4; and UM 9304, fig. 5. The large suite of specimens allows statistical investigation of variation in arm branching structure. Most of the raw data are given in Brower (1966, table 2); summary statistics are listed in Table 2. Scrutiny of the table denotes that the branching structure of the proximal parts of the axil arms is subject to low variation. In fact, the observed variation is much lower than in roughly con- temporary species of Anulocrinus from the Bromide Limestone of Oklahoma (see Brower 1966, table 1; Brower, 1977). This reveals that the arm structure of Cremacrinus is essentially stabilized where- as that of Anulocrinus was subject to more variation, presumably genetic in nature. The specimens also provide information about ontogeny, most of which is similar to that reported by Kolata (1975, pp. 21, 23). Throughout the observed growth, the dorsal cup plates become more nodose, suggesting that most calcite accretion involves thickness of the plates. Roughly analogous changes in the axil arms are the result of predominant thickness and width growth of the brachials. Height of the brachials remains more constant. Development of the brachials is adjusted so that the knuckle-like joints become more pronounced with age. When discussing the origin of the Calceocrinidae, Sardeson (1928, pp. 36-40) also speculated on the relations of dicyclic and monocyclic crinoids. He believed that monocyclic crinoids such as Heterocrinus could be derived from dicyclic forms by rotating the radial circlet relative to the basal circlet so that the radials line up directly over the basals (see Sardeson, 1928, pl. ii, figs. 9-11). Fusion of the radials with the underlying basals would produce a mono- cyclic crinoid with two circlets of plates. The upper circlet of the monocyclic form would represent the radials which are homologous with both the radials and basals of a dicyclic crinoid. The lower circlet of the monocyclic form would be called the basals, the plates of which would match up with the infrabasals of dicyclic crinoids. 460 BuLueTin 304 Sardeson thought that dicyclic forms were generally ancestral to monocyclic ones. Sardeson viewed monocylic inadunate crinoids with two or three compound radials, such as Heterocrinus and Ecteno- crinus (see Moore, 1962b for review of calyx structure in these crinoids), as intermediate steps. The large or undivided radials of these monocyclic inadunates would consist of the fused basals and radials of the ancestral dicyclic crinoid. In the compound or divided radials of the monocyclic inadunate, the infraradials are equivalent to the basals of dicyclic crinoids and the superradials of the mono- cyclic crinoid would be homologous with the radials of the dicyclic ancestor. This idea is geometrically intriguing and reasonable. Al- though the Sardeson hypothesis certainly deserves further study, it has been ignored by most crinoid specialists (e.g., Moore and Lau- don, 1943; Ubaghs, 1953; Warn, 1975). The reasons for this are probably two-fold. First, Sardeson’s work was and still is not well known. Second, most crinoid workers view the radials as the basic plates of all crinoids, and the homologies of the other plates are designated with respect to the radials. Thus the radials are consid- ered as static and unchanging elements. The Sardeson hypothesis treats the radials as more dynamic elements with different homo- logies in monocyclic vs. dicyclic crinoids. Our plea is simply that the Sardeson hypothesis on the relations of monocyclic and dicyclic crinoids should be exhumed and evaluated. Sardeson pictured the evolution from dicyclic to monocyclic in terms of adult crinoids. The studies of Brower (1974a) on plate development sequences in camerate and living crinoids show that these divergences could be introduced more easily into the ontogeny of embryonic crinoids. Turning to the ancestry of the Calceocrinidae, Sardeson (1928) followed Springer (1926, pp. 88-104) and suggested that calceo- crinids were descended from a “heterocrinid” with compound radials in the B, C and E rays (at that time both true heterocrinids with two compound radials and homocrinids with three compound radials were commonly lumped together under the term heterocrinids). This view has been accepted by all subsequent workers (e.g. Moore, 1962a; Brower, 1966; Kesling and Sigler, 1969). Sardeson further noted that in 1928, C. arctus was the oldest known calceocrinid and thus was critical to the evolution of the group. Since 1928, additional calceocrinids have been discovered. At present, the oldest calceo- 461 BROWER & VEINUS MippLe OrpoviciIAN CRINOIDS Wr‘ 0 £t'0 97 $-¢ It? %0'0 00°0 8 c-C 00°2 Arb 0% $20 L eT 98'T %8'st 0£°0 IT c-T T6T Mb et 820 eT £-¢ 80°C M6 ct $z'0 9T oT tol Mest 9£°0 oT £-1 00°2 % 601 c2'0 02 £-¢ $0°C %S et £70 tb £-T 861 uOT}eIIeA JO uonelAap so] dwmexq asuey uvayy JUITITFJIOD piepueys jo raquinyy Ael g jo s[ixewlig shel Q pue VY Ul Wie [IxeIpunoas fo syoeiqemWey) skel q pue Vy Ul Wie [IxeIpunoas fo syoviquiag shel q pue Vy Ul We [IxeIpundas jo syoviqeyd]y sXvel q pue y jo s[ixerpunoag sABI q put Y Ul Wie [Ixeuid fo syoviqewuwes shel q pue VY UI Wie [Ixewlid fo syoeiqejag sXel q pue y ur wie [Ixewtid jo syoeiqeydiy shel q pue Vy jo s[ixeullig salias [elyoeiq Jo uoNeI0T UOSIPILS SNJIAD SNULIIVUI 47) UL IINONAYS SUIYIULIG WIe JO UOHPIIE A @ FIL 462 BuLLeTin 304 crinid is an undescribed cremacrinid-like genus from the Mountain Lake Member of the Bromide Formation which is probably Late Chazyan (Middle Ordovician) in age (Cooper, 1956, p. 123). Slight- ly younger species of Cremacrinus, Anulocrinus and Calceocrinus occur in Black River units such as the Pooleville Member of the Bromide Formation and the Platteville of the Twin Cities area. Sardeson (1928, pp. 43-46) suggested that C. arctus lived in a quiet water environment that was only swept by gentle currents. The fine-grained sedimentary rocks in which the crinoids are found seem to support this contention. Quiet water is also indicated by epifaunal brachiopods such as Dinorthis deflecta (Conrad) that are found in living orientation with the interarea pressed down on the substrate. Specimens of Cremacrinus arctus also occur in living posi- tion. The cremacrinids are preserved on the lower surfaces of bed- ding planes with individuals of Cupulocrinus gracilis, an unidentified camerate crinoid, and various brachiopods. Most of the crinoids were collected from the same place and presumably are the remains of a single large colony. The dorsal cup was mostly buried in the sediment (Text-fig. 8). Sardeson (1928, p. 43) thought that the hinge was closed, but most individuals exhibit a slightly open hinge. The stem is not completely known but the preserved part of the stem is recurved with its distal end set in the sediment around the calyx. Sardeson (1928, pp. 45, 46) believed that the stem was broken during life of the crinoid and he speculated that the young animals were anchored to seaweeds. With progressive age, the crinoid became larger and eventually the stem broke when it was too weak to support the crinoid. After this traumatic experience, the cremacrinids fell to the seafloor where some animals continued to prosper. According to Sardeson’s inter- pretation (1928, p. 45), the common fucoidal markings in the Upper Platteville of the Twin Cities represent traces of the seaweeds. We propose an alternate idea. As mentioned above, most of the speci- mens are found on lower bedding surfaces of sedimentation units. In most, stems and roots were probably present but were buried in the sedimentation unit below the crinoid. Probably the distal parts of the stems and the roots broke when the specimens were col- lected. Thus we envision C. arctus as exploiting a bottom-dwelling niche throughout life. 463 Brower & VEINUS =| fo) Sg me (©) Zz S| = > ie) a oe) es - a =| ‘OHBWAYIS st Yd}ay¥s ayy, ‘dno [es1op pating-Ajjenied pue sure ay} so UONLIUITIO [MOq-BuTda][09 10 aqoyd “O94 AjJOU SUOSapIES smjI4v snuLsvULIL Jo UOHeIOJSaY —*g aINZIJ-3x9 7, F740 ff eg e 7 o Me Vil sse my oe ae ‘ A Tee ss ah ae be oe wr Liz dee no er: rite ag TONLE OCI TER INE tee MIE SE ) tet ; : 3 mae ¥ me = yy eee e, p POET © > Mp a ST a CO % S EE TES nae og OLE cp eRe aa ERTIES SOT TTT gL Le a oS] / IIT T/ / , 464 BuLvetin 304 Judging from the orientations of the arms of preserved speci- mens, the A, B and D rays were spread upward and outward to form a collecting bowl just above the substrate. This would be a substrate- level version of the rheophobe feeding posture (Breimer, 1969) that is thought to characterize many crinoids that lived in quiet waters. It does not seem likely that any of the arms of C. arctus rested on the seabed, as suggested by Ettensohn (1975, pp. 1052-1058, text- fig. 8) for Agassizocrinus lobatus Springer, a dicyclic inadunate of Mississippian age. Resting the arms on the substrate would present the obvious hazard of sediment fouling the food grooves. The proxi- mal parts of the main arms of Cremacrinus arctus are straight or slightly curved, but the distal portions are commonly more curved. This suggests that the proximal parts of the arms were held relative- ly rigid but that the distal tips were more flexible. This is confirmed by the brachial sutures in the proximal arms. The sutures between the axillary brachials and the underlying non-axillary brachials are almost fused in most specimens; some movement was possible along the sutures between the axillaries and the overlying non-axillary brachials. In the distal parts of the arms, none of the sutures show traces of fusion. The long thin ramules were also probably rigid, with most movement occurring along the suture between the axillary brachial and the ramule. The slender E ray arm is commonly curved and may have been more flexible than the axil arms of the A, B, and D rays. The E ray may have served any of three functions: food gathering; bracing against the seafloor; or grasping some object on the substrate, as implied by Sardeson (1928, pp. 44, 45). Sardeson (1928, pp. 44, 45) postulated that the hinge of Crema- crinus arctus was non-functional because the calyx was partially buried. The hinges of the available specimens range from fully closed to partly open. This shows that although the hinge was used, its range of movement was restricted relative to other Ordovician cremacrinids (see discussion of C. punctatus Ulrich). Thus Sarde- son’s conclusion was basically correct. We think that the hinge of C. arctus was functional but not in the usual fashion. When the hinge was open, the arms were spread to form a collecting bowl. Closure of the hinge may have been associated with closure of the arms. During the resting or non-feeding orientation, the arms were Mipp te OrpoviciaN CrINoOIDS: BROWER & VEINUS 465 probably almost vertical with respect to the substrate rather than horizontal and parallel to the seabed as in most calceocrinids (see Brower, 1966; Kesling and Sigler, 1969). Burial positions denote that the anal tube was rigid and held at a steeper angle than the arms when the crinoids were feeding. Kesling and Sigler (1969, text-figs. 2, 3, 11, 12) restored their calceo- crinids in the same way. The vertical anal tube would allow fecal material to be carried “down stream” by the gentle currents in the area. In summary, C. arctus was a quiet water crinoid that lived with the calyx partly buried in the sediment; when feeding, the arms were spread horizontally to form a collecting bowl. C. arctus did not maintain a vertical filtration net as did most calceocrinids that are found in rocks representing more agitated environments (e.g., com- pare Text-fig. 8 with text-fig. 13 of Kesling and Sigler, 1969). Our ongoing studies of calceocrinid phylogeny indicate that C. arctus was descended from calceocrinids with normal hinge mobility. There- fore, the restricted movement on the hinge of C. arctus constitutes specialization. We consider that this character was adaptative to partial burial of the dorsal cup in the seabed and to exploitation of a rheophobe, or collecting-bowl feeding orientation. Other crinoids, exemplified by Agassizocrinus lobatus, developed a similar substrate- dwelling life style. However, A. Jobatus and other crinoids with roughly equivalent life habits were produced by convergent evolu- tion in unrelated stocks (Calceocrinids were derived from mono- cyclic homocrinids, whereas Agassizocrinus is a dicyclic form). As noted by Sardeson (1928, pp. 40, 41), the characteristic features of C. arctus are the moderately coarse punctate surface, anal tube with strong median ridge, nodose dorsal cup plates, long slender unbranched E ray arm, and long and heavy A, B and D ray arms with knuckle-like enlargements of the arms where the ramules originate. C. punctatus Ulrich (1886, pp. 106, 107, fig. 1; see Springer, 1926, pl. 28, figs. 16-20; herein) occurs in the overlying Decorah of the Twin Cities. C. punctatus differs from C. arctus in having coarser punctation and in lacking the knuckle-like axillaries in the A, B and D ray arms. The E ray arm of C. punctatus is much heavier and a ridge is absent on the anal tube. 466 BuLietin 304 Most other Middle Ordovician species of Cremacrinus, namely C. articulosus (E. Billings) (1859, p. 51, pl. 4, fig. 8; see Springer, 1926, p. 108, pl. 28, figs. 9-13; Wilson, 1946, p. 35, pl. 6, fig. 5), C. billingsianus (Ringueberg) (1889, p. 394, pl. 10, figs. 3a-c), C. fur- cillatus (W.

Typically these forms are smaller and possess more slender crowns than in C. arctus. In addition, fewer arm branches occur and there are more brachials between the ad- jacent branches of the axil arms in C. articulosus and the other forms; commonly the third or fourth brachial is axillary in most Middle Ordovician cremacrinids but alternate brachials are axillary in C. arctus. The E ray arm of some of these forms such as C. furcillatus and C. kentuckiensis is branched in contrast to the unbranched arm of C. arctus. In C. arctus, the E ray arm is more slender than in the other taxa, the other forms also lack strongly nodose dorsal cup plates and a prominent ridge on the anal tube. C. lucifer Bolton (1970, p. 62, pl. 13, figs. 2,3) from the Middle Ordovician of Ontario is a massive animal with a partial crown that is 42 cm high; this specimen is the largest known calceocrinid. C. lucifer is characterized by heavier arms with fewer and more widely spaced branches which lack the knuckle-like joints of C. arctus.

Diagnosis. — A species of Cremacrinus with coarse punctae on all plates; E ray arm unbranched as far as known; B ray arm large relative to those in the A and D rays; axillaries moderately nodose. Description. — Crown slender. Calyx plates coarsely punctate with punctae diameter from 0.1 to 0.4 mm; dorsal cup plates slightly nodose; axillaries with weakly developed knuckle-like areas at ramu- lar bases; axillaries twisted, ramules not fully visible laterally. Basal series triangular, of four plates; stem facet on all four plates. E ray inferradial rectangular with central constriction, height/ width almost 2.0; superradial rectangular, height/width from 0.5 to 0.7.

Radial facets with sharp transverse ridge and distinct dorsal liga- ment pit; ventral ligament pits broad, not well-defined. Two main axil series, generally two plates in each series; proximal plate rec- tangular, non-axillary, height/width 0.5; distal plate axillary, penta- gonal, height/width 0.6. Axil arms structured as in most crema- crinids. Alphabrachs, commonly two, rarely three; two or three beta- brachs; gammabrachs and higher brachs commonly of three, rarely four, plates; axil arms of largest specimen branching at least six times. Axil arms somewhat geniculate, with axillaries slightly twisted, ramules not fully visible with arms closed. Non-axillaries 468 BuLLeTiIn 304 rectangular; height/width from 0.75 to 0.9. Axillaries asymmetrical- ly pentagonal; height/width from 0.7 to 1.0. Articular surfaces of non-axillary brachials smooth. Proximal ramules long, slender, of at least 20 plates; ramulars rectangular, with height/width about 1.0 to 13. B and C rays with compound radials.

Only proximal portion of anal tube preserved, consisting of large rectangular plates; distal part of anal tube tucked inside the closed arms. B and C ray superradials grooved for reception of column when the crown is in the closed position. Column not fully known, round, made up of slightly nodose columnals; stem at least as long as crown is high. Distal portion of stem and attachment device not preserved. Remarks. — Nineteen specimens can be placed in this species; most of the material consists of dorsal cups with short parts of the arms attached. The best specimen is the holotype, NMNH 89879, a nearly complete crown. Almost all specimens have the hinge closed or nearly so; these crinoids apparently were buried in the resting orientation (See Brower, 1966; Kesling and Sigler, 1969 for living habits in calcocrinids). A long stem segment attached to UM 9321 indicates that the stem length exceeded the crown height in this form. Some calceocrinid stems are shorter than the crown, for exam- ple “Calceocrinus? n. sp.” from the Middle Ordovician Bromide Limestone of Oklahoma (Brower, 1966, pl. 75, fig. 24, text-fig. 1k). One specimen in the NMNH (S) 2156 suite of crinoids exhibits an open hinge; the animal may have died while feeding. As mentioned above, C. arctus was a rheophobe cremacrinid that was specialized for living in quiet water. Conversely, C. punctatus is found in coarse- grained sedimentary rocks in association with much bioclastic debris made up of bryozoans, crinoids, etc. This denotes that the habitat of C. punctatus was agitated and probably formed in shallow water close to shore (Sardeson, 1928, p. 46). Thus C. punctatus was ob- viously adapted to a rheophile existence (see Breimer, 1969 for gen- MippLeE OrpoviciaNn Crinoips: BROWER & VEINUS 469 eral discussion of rheophobe and rheophile life habits in crinoids). One of the major adaptations to this life habit may have been the fully functional hinge of C. punctatus (compare the partially func- tional hinge of C. arctus). C. punctatus is similar to many other Middle Ordovician crema- crinids which are punctate and have similar types of arms. Some of these taxa may eventually have to be placed in synonymy, but we have not examined any of the type material, and nomenclatural changes are not proposed here. The problem is complicated by the loss of types for C. billingstanus (Ringueberg) and C. furcillatus (W. R. Billings) (Wilson, 1946, p. 35). The species that are most closely allied to C. punctatus are C. articulosus (E. Billings) (see Springer, 1926, p. 108, pl. 28, figs. 9-13; Wilson, 1946, p. 35, pl. 6, fig. 5), C. billingsianus (Ringueberg) (1889, p. 394, pl. 10, figs. 3a-c), C. inaequalis (E. Billings) (see Wilson, 1946, pl. 5, figs. 4a, b), C. rugosus (W. R. Billings) (see Ringueberg, 1889, p. 393, pl. 10, fig. 2), and C. kentuckiensis (Miller and Gurley) (see Springer, 1926, p. 109, pl. 28, figs. 14, 15). The punctae of C. punctatus are coarser than in the other crinoids. In addition, C. punctatus has a smaller B ray arm and axillaries and dorsal cup plates with shapes that are different from those in the taxa listed above. The comparison between C. arctus and C. punctatus was given above. C. furcillatus (W. R. Billings) (1887, p. 51, unnumbered fig.) possesses an E ray which branches several times near the calyx, vs. the unbranched E ray of the Twin Cities species. C. lucifer Bolton (1970, p. 62, pl. 13, figs. 2, 3) is a much larger animal with a more robust dorsal cup and heavier arms, and finer punctae with respect to size of the crown. C. guttenbergensis Kolata (1975, p. 23, pl. 3, figs. 10, 14, text- fig. 6) and C. punctatus are both coarsely punctate. However, less nodose axillaries, a smaller cup, and a relatively smaller B ray arm are seen in the former species. All Silurian cremacrinids, C. decatur Springer (1926, p. 107, pl. 28, fig. 7), C. twbuliferus Springer (1926, p. 106, pl. 26, figs. 3-6) and C. wlricht Springer (1926, p. 105, pl. 28, figs. 1, 2) lack the punctae that are diagnostic of C. punctatus.

CRINOID ATTACHMENT DEVICES Remarks. — By 1908, Sardeson had evolved an ingenious sys- tem for the classification of crinoid attachment devices found in the Twin Cities area. The basic idea was a marriage of non-biological or form nomenclature with a formal biological classification. Sarde- son (1908, p. 242) grouped all primitive discoid or conical crinoid root structures with more or less lobate margins and a basal fixing plate where the area about the stem scar is not depressed, into the form genus Podolithus. Incidentally the generic name, which means “stone foot,” seems highly appropriate. The trivial names for podo- lithids were derived from the genera to which the roots belonged. For example, P. dendrocrinus included roots which belonged to various dendrocrinids; roots of Strophocrinus were placed in P. strophocrinus and so on. Previous to 1908, Sardeson had collected large suites of holdfasts of various types, stems and a smaller num- ber of calyces. Although Sardeson did not systematically label most of the crinoids by exact locality (most labels read “St. Paul” or “Minneapolis”), he did keep together specimens which were ob- tained from the same locality. Thus Sardeson knew which holdfasts were found with which calyces. As of 1908 Sardeson had identified most of the Twin Cities calyces to the generic level except for cara- bocrinids, which were treated at the species level. In associating hold- fasts with crinoids, Sardeson used two criteria. The morphology of the base had to be compatible with the calyx, e.g. small holdfasts probably did not belong to large crowns, and so on. Sardeson also rea- soned that the holdfasts most likely belonged to the crowns with which they occurred; thus information on associations was clearly recognized (see Brower, 1973 for the same methods on Upper Ordo- vician crinoids). Although ingenious, Sardeson’s type of nomencla- ture has not been adopted by any other crinoid specialists. There are several obvious reasons for this. First, one cannot usually match Mipp_e OrpoviciIAN CRINOIDS: BROWER & VEINUS 471 holdfasts with crowns. As practiced by him, Sardeson’s classification system assumed that the roots could be associated with the calyces. However, this is not inherent in the Podolithus scheme; any “species” that fitted the morphological criteria could be placed in Podohtthus. Second, most crinoid specialists have shown little inter- est in attachment devices and stems; crinoid literature deals almost exclusively with calyces. Third, the Sardeson system is not allowed under the current rules of the International Commission on Zoolo- gical Nomenclature. When proposing Podolithus, Sardeson described five “species”: P. strophocrinus [for roots of Carabocrinus dicyclicus (Sardeson), discussed above], P. schizocrinus, P. anomalocrinus, P. eucheiro- crinus and P. dendrocrinus. The type material for P. strophocrinus, P. anomalocrinus, and the stem for P. dendrocrinus are in the Sarde- son collection, but the other specimens have been lost. Nevertheless, Sardeson’s descriptions and illustrations are sufficiently detailed that one can reconstruct his conceptions of the “species” of Podolithus. One of the most striking aspects of the Twin Cities holdfasts and roots is that the sediments were not suitable for the attachment of crinoids. Judging from the material assembled by Sardeson, D. Wallace of the University of Minnesota, and others, virtually all of the crinoids were attached to brachiopod shells and bryozoan colonies. The two most common attachment devices are the lobate and digitate holdfasts that were cemented to bryozoans, and the lichenocrinid holdfasts found on brachiopod shells and bryozoans. Holdfasts rooted in or cemented to the substrate are less abundant. The most common are the bases of Carabocrinus, that were cemented directly to the seabed.

Paper 45, p. 537. Remarks. —Lichenocrinid bases are common in the Twin Cities area. We have examined over 50 examples from the Platte- ville and Decorah attached to different substrates. Hall (1866, p. 9) proposed the genus Lichenocrinus believing that it consisted of the “bodies” of parasitic crinoids which were usually attached to the shells or skeletons of other animals. However, almost all subsequent workers considered Lichenocrinus as bases or holdfasts of crinoids (see Warn and Strimple, 1977, pp. 49-52 for review; Faber, 1929, for morphological details). Warn and Strimple (1977, p. 30) aptly observed that Lichenocrinus represents an omnium gatherum for multi-plated discoidal bases of Ordovician crinoids belonging to the juvenile Cincinnaticrinacea, Homocrinacea and possibly some allied groups. Several complete specimens of either or both cincinnati- crinids and homocrinids with lichenocrinid holdfasts, collected by G. M. Austin, C. L. Faber, G. Ashman, and A. Albers in and around Cincinnati, Ohio, have been reported in the literature, but this ma- terial has been lost (according to Warn and Strimple, 1977, p. 51). Fenton (1929a) reviewed some of this material and commented that lichenocrinids were commonly associated with cincinnaticrinids and homocrinids. Based on morphology and association, Warn and Strimple suggested that small and adult individuals of Cinctnnati- crinus varibrachialis Warn and Strimple (1977, p. 41, pls. 3-5, text- fig. 8), small specimens of the homocrinid Ectenocrinus simplex (Hall) (see Warn and Strimple, 1977, p. 84, pls. 12-14, text-fig. 20), and possibly some related crinoids possessed lichenocrinid attach- ment disks. We accept the consensus of most crinoid specialists that most lichenocrinids are probably the holdfasts of cincinnaticrinids, homocrinids, and similar forms. The Twin Cities lichenocrinids are not associated with any specific crinoids as far as we can determine. It is notable that only Mippbte OrpovicIAN Crinoips: BROWER & VEINUS 473 two cincinnaticrinid specimens, /sotomocrinus tenuis and a form of unknown affinities, have been found in the Twin Cities area. The abundance of lichenocrinids, the rarity of cincinnaticrinids, and the absence of homocrinids in the Twin Cities fauna implies that other crinoids may have had lichenocrinid bases. The basic construction of a lichenocrinid is simple (details in Faber, 1929). The basal or floor plate is cemented to the substratum; this plate is typically round with a series of radiating ridges. The roofing or overlying layer is polyplated and contains a crater or depression in the center where the column is attached. All of the distal columns or column scars that we have seen are pentagonal or pentalobate in outline. The Twin Cities material varies in height relative to diameter, size of the depression or crater, size and regularity of the plates, and ornamentation. Fenton (1929b) listed seven species and subspecies from the Twin Cities area. We have not been able to identify these taxa consistently, as they show some morphological overlap. Follow- ing Warn and Strimple (1977, p. 51), we will not recognize Licheno- crinus and species described under the genus until complete speci- mens are available for establishment of a definitive taxonomy. There- fore, we lump all of the Twin Cities forms in the informal category of lichenocrinid holdfasts. The Twin Cities specimens are cemented to various objects as follows. Most holdfasts are attached to the outside of brachiopod shells (74%) and bryozoans (15%). A few bases are found on the seafloor (5.7%), on the interior of brachiopod shells (3.8%), and on a carbonate pebble on the seabed (1.9%). Of the lichenocrinids located on organic objects, those on the interior of brachiopod shells obviously settled on dead shells, but the lichenocrinids adhering to the exterior of brachiopod shells or bryozoans could have attached during or after the life of the host organism.

Podolithus anomalocrinus Sardeson, Jour. Geol., vol. 16, p. 246, figs. 18, 19. 1915. Podolithus anomalocrinus Sardeson, Bassler, U.S. Nat. Mus. Bull. 92, p. 1017. 1943. Podolithus anomalocrinus Sardeson, Bassler and Moodey, Geol. Soc. America Spec. Paper 45, p. 636. Remarks. — Only one Twin Cities specimen of this root form is known. Sardeson observed that the disk was apparently cemented to a pebble comprised of the inside of a receptaculitid. The layer overlying the fixing plate is polyplated and grades upward into a large stem with a pentalobate axial canal. The surfaces of the plates bear small canals that form pores along the sutures between the plates of the upper layer and the column. A rigid suture was prob- ably formed. Sardeson thought that this attachment device be- longed to Anomalocrinus because Meek (1873, p. 18, pl. 2, figs. 6d, e) found similar structures which were attributed to Anomalocrinus incuruus (Meek and Worthen). However, anomalocrinids have not been found in the Twin Cities area and the attachment device may represent part of another crinoid. Figured specimen. — UM 9360, which is also the type of Podo- lithus anomalocrinus Sardeson. Occurrence. — Decorah Shale, Bed 6 of Sardeson: below Man- torville, Minnesota. TREE-STUMP-LIKE CiRRUS ROOT Pl. 25, fig. 6 Remarks. — Several incomplete specimens of this root type ap- pear on a small slab from the Twin Cities Brick Plant. Although the distal end of the root is not visible, several large cirri that were buried in the substrate may be seen. The sediment is a mixture of fossil debris and sand- and silt-sized particles. The stem is round and the columnals have crenulate articular surfaces. The sutures between the distal columnals probably were rigid, so that the stalk could be flexed against a rigid base. An unusual feature is the ap- parent lack of an axial canal in the distal part of the stem. The Mppie OrpoviciaAN Crinoips: Brower & VEINUS 475 animals with this type of rooting device are not known but the size of the root is consistent with a large crinoid. Almost any large form, such as Pycnocrinus sardesont, n. sp., known to occur at the Twin Cities Brick Plant, could have developed this root form. Figured specimen. — UM 9345, in the collection of D. Wallace. Occurrence. — Decorah Shale, Bed 5 of Sardeson: Twin Cities Brick Plant, St. Paul. STEM WITH GRASPING CiRRI ON BRYOZOAN Pl. 24, fig. 19 Remarks. — This root form is represented by a single specimen. The stem is round and gives off a series of long, round cirri that are wrapped around a broken broyozoan colony. The species with this attachment device is unknown. Figured specrmen.— UM 9354. Occurrence. — Decorah Shale, Bed 5 of Sardeson: St. Paul. LoBATE AND DiGITATE HOLDFASTS CEMENTED TO BRYOZOANS Pl. 25, figs. 1-5 Remarks. — This attachment device is the most common one in the Decorah fauna. Although the types of the holdfasts described by Sardeson as Podolithus schizocrinus (1908, p. 244, figs. 11-17) and P. dendrocrinus (1908, p. 248, figs. 24-25) are lost, both are probably synonymous with our lobate and digitate forms. P. dendro- crinus resembles UM 9341, 9342 and 9344, and specimens such as UM 9338 and 9339 fall into the P. schizocrinus category. All or virtually all of these holdfasts are cemented to broken branches or ramose bryozoans. Portions of some of these attachment devices ap- pear to penetrate the zooecia of the bryozoans and probably formed after death of the host. Other specimens may have grown on bryozoan colonies that were alive and erect. These holdfasts exhibit great variation in outline. The number of branches ranges from four or five to about 20. Some branches are long and slender but these grade into short and stubby ones. Some holdfast branches remain unbranched whereas others bifurcate one or more times. All variations seem to intergrade. Inasmuch as the lobate and digitate holdfasts are the most com- mon type of attachment device in the Decorah Shale, it is probable that several crinoid species were characterized by these structures. 476 BuL_eTin 304 Two crowns are probably directly associated with this device. The young specimens of Cupulocrinus jewetti (UM 9283), and Gren- prisia billingsi (UM 9271), are both found on bryozoans. The first has a complete stem that disappears under a ramose bryozoan; the column probably attached to a lobate or digitate holdfast on the underside of the bryozoan. The young G. billings is lying on a bryo- zoan that it may have used as a substrate during life. Many other crinoids from the Decorah of the Twin Cities area are associated with bryozoans; these may also have exploited this means of fixation.

The Bulletins are a publication outlet for significant longer paleontological, paleoecological and biostratigraphic monographs for which high quality photographic illustrations are a requisite. Manuscripts submitted for publication in Bulletins of American Paleontology must be typewritten, and double-spaced throughout (including direct quotations and references). All manuscripts should contain a table of contents, lists of text-figures and/or tables, and a short, informative abstract that includes names of all new taxa. Format shou!d follow that of recent numbers in the series. All measurements must be stated in the metric system, alone or in addition to the English system equivalent. The maximum dimensions for photographic plates are 114 x 178 mm (4%4” x 7”: plate area is outlined on this page). Single-page text-figures are limited to 108 x 178 mm (4%4” x 7”), but arrangements can be made to publish text-figures that must be larger. Any lettering in illustrations should follow the recommendations of Collinson (1962). Authors must provide three (3) copies of the text and two (2) copies of accompanying illustrative material. The text and line-drawings may be repro- duced xerographically, but glossy prints at publication scale must be supplied for all half-tone illustrations and photographic plates. These prints should be clearly identified on the back. All dated text-citations must be referenced, except those that appear only within long-form synonymies. Additional references may be listed separately if their importance can be demonstrated by a short general comment, or in- dividual annotations. Citations of illustrations within the monograph bear initial capitals (e.g., Plate, Text-figure), but citations of illustrations in other articles appear in lower-case letters (e.g., plate, text-figure). Original plate photomounts should have oversize cardboard backing and strong tracing paper overlays. These photomounts should be retained by the author until the manuscript has formally been accepted for publication. Explana- tions of text-figures should be interleaved on separate numbered pages within the text, and the approximate position of the text-figure in the text should be indicated. Explanations of plates follow the Bibliography. Authors are requested to enclose $10 with each manuscript submitted, to cover costs of postage during the review process. Collinson, J. 1962.
