"The four plates that constitute the sole known remains of Glyptaspis verrucosa Newberry are identified and described. The identification of these elements allows them to be properly placed and fitted relative to one another and permits a complete reconstruction and restoration of the ventral thoracic armor. On the basis of the detailed anatomical study of these plates it is possible to rule out speculations of previous authors that the ventral armor plates of Glyptaspis verrucosa might actually be the ventral plates of Mylostoma or Diplognathus. The present study also serves as a foundation for speculation on the biomenchanics of feeding in Glyptaspis"--P. [1]
