Common Functional Correlates of Head-Strike Behavior in the Pachycephalosaur Stegoceras validum (Ornithischia, Dinosauria) and Combative Artiodactyls
Figure 5
Comparison of sagittal-section densities in crania of Stegoceras validum (UA 2) and Cephalophus leucogaster (AMNH 52802).
A, B, C. Sagittal sections through the cranium of Stegoceras validum, at positions shown in the dorsal view (top). D, E, F. Sections through the cranium of Cephalophus leucogaster, at positions shown in the dorsal inset (top). Note similar stratification of compact and cancellous layers in F, through the middle of the duiker's lobate dome, and B, through the center of the pachycephalosaur's dome. ec = endocranial cavity.
