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 modern rams, while others contend it may have been a sexual display. They were either an herbivore or omnivore with small leaf-shaped teeth effective for shredding plants.

There are more than a dozen described genera of Pachycephalosaurs, though Pachycephalosaurus from the Hell Creek Formation is the best known.
