Horned dinosaurs (ceratopsians) evolved in Asia 160 million years ago, then colonised North America about 110 million years ago and Europe by 85 million years ago. The first ceratopsians were small, walked on two legs (bipedal) and lacked the large frill and facial horns of later species. Towards the end of the Cretaceous Period, gigantic species evolved and were among the most common dinosaurs in Laramidia, a huge island that formed when the rising sea level divided North America into several continental islands. 75 million years ago, the eastern coastal plain of Laramidia supported the highest diversity of giant herbivores recorded anywhere. Several ceratopsians, including Styracosaurus, co-existed there with numerous species of duckbill dinosaurs, ankylosaurs and other large ornithischians
