A Helmet of Bone

Pachycephalosaurus had a skull dome of solid bone several inches thick. This Cretaceous dinosaur skull was about 3 m (10 ft) long and walked on two legs.

The medium Pachycephalosaurus dome offers more surface to study the dense, fine-grained bone.

Head-Butter or Show-Off?

Some scientists think males used the dome in head-butting contests, like rams. Others think it was mainly for display, or had several uses, like deer antlers.

This Hell Creek dome fragment lets you judge the bone yourself. Browse more in our Prehistoric Collection and Authentic Fossil Specimens.

About Pachycephalosaurus

Pachycephalosaurus lived in the Late Cretaceous, about 69 to 66 million years ago. Fossils come from Montana, South Dakota, Wyoming and Alberta. It was probably a plant eater in a subtropical land. Every Cretaceous dinosaur skull piece from that time is a window into its anatomy.
