Abelisaurs were a group of ceratosaurian dinosaurs which lived in the southern hemisphere (with the exception of Tarascosaurus in Southern Europe) during the Cretaceous period. Some well-known dinosaurs of this group include Abelisaurus, Carnotaurus, and Majungasaurus. They are known for their small arms. Some members had ornamented heads, such as Carnotaurus and Majungasaurus; the horns and knobs may have been used for display.
