The Suborder Pachycephalosauria was recently named for a group of two legged plant eating dinosaurs that had enormously thick skull roof's. The skull roof was up to 10in (25cm) thick, and for that reason, this part of the animal is easily fossilized. Many of these dinosaurs are only known from the skull roofs.
