Pachycephalosaurs are a family of bipedal dinosaurs that lived during the Late Cretaceous and had a distinctive, large, bony dome on top of their skull. This dome was sometimes up to 10 inches thick and was thought to cushion their brain from impacts. Some paleontologists believe this thick skull may have been used for head-butting, much like rams while others contend it may have been a sexual display. They were either a herbivore or an omnivore with small leaf shaped teeth which would have been very effective at shredding plants.

There are more than a dozen described genus of Pachycephalosaurs with Pachycephalosaurus from the Hell Creek Formation being the best known.
