Brontotholus

Brontotholus is a relatively large pachycephalosaurian dinosaur. Like all pachycephalosaurs, it was bipedal and sported the characteristic bony dome on top of its skull. Brontotholus grew to nearly 4 m in length, making it one of the largest known pachycephalosaurs, and the largest from the Campanian age.
