Pachycephalosaurus is a small herbivorous dinosaur in The Isle.

In Real life

It lived during the Late Cretaceous Period (Maastrichtian stage) of what is now North America. Remains have been excavated in Montana, South Dakota, and Wyoming. It was a herbivorous creature which is primarily known from a single skull and a few extremely thick skull roofs, though more complete fossils have been found in recent years. Pachycephalosaurus was one of the last non-avian dinosaurs before the Cretaceous–Paleogene extinction event. Another dinosaur, Tylosteus of western North America, has been synonymized with Pachycephalosaurus, as have the genera Stygimoloch and Dracorex in some recent studies.

In The Isle

It's headbutt attack can cripple even large carnivores, though it is generally best to avoid them and run away when being attacked. You can easily fight smaller carnivores however. It is recommended that you live in a herd so you can have extra protection. Try not to engage in combat.
