A crested ornithopod is indicated by a small group of teeth, AMNH 8527 from Clambank Hollow, which are markedly different from those of Kritosaurus (fig. 8W, X). The teeth are large, with a long, narrow and elongated enamel face having a prominently raised medial keel. Sides of the enamel face are ornamented toward the apex of the crown with small papillae. Unlike teeth of Kritosaurus , the crown is not diamondshaped but is rectangular in lateral view.

The teeth, which vary greatly in size, closely resemble teeth of Trachodon (Pteropelyx) altidens Lambe (1902 , pl. 4, fig. 4). The species was later tentatively transferred to the genus Procheneosaurus by Lull and Wright (1942, pp. 222-223).
