Figure 16 View Figure 16

Material. — DMNH 32649 portion of skullcap (Denver Formation, Loc. 20).

Description and discussion. — A portion of thickened parietal is all that is present of the skull roof ( Fig. 16 View Figure 16 ). The bone is very dense, making identification as pachycephalosaurid certain. The outer surface is moderately grooved; no nodes are present on the specimen, indicating that the fragment is not from the periphery of the skull.
