Its name means "level head" because it had a flat top to its skull. There were several bumps on the top of its head and a pattern of small pits. Most remains come from Mongolia and it was probably about 10 feet long. Homalocephale was one of the large family of "bone-head" dinosaurs that lived about 70 million years ago. They are thought to have descended from the family of Heterodontosaurus dinosaurs, which lived more than 110 million years earlier. Homalocephale was closely related to Pachycephalosaurus.
Like other members of its family, Homalocephale had a very thick skull. This may have been used to attack others that tried to invade its territory, or it may have been used to play. Animals of today often heads in play. Homalocephale probably lived on high slopes and on the sides of mountains. Most of its fossil remains have been washed down from high places by fast-flowing streams. These animals walked on their back legs, using their tails as props when standing.
