Their compact build and thick, bony skulls made pachycephalosaurs the rams or bighorn sheep of their day. Not all pachycephalosaurs were large, as this little Stegoceras illustrates. Cast from a skeleton that is over 75% complete, our replica is of superior quality. It is more than adequate as a stand-alone exhibit, but is striking when integrated into a diorama with other skeletons.
