Arctocyonia
Extinct clade of mammals
From Wikipedia, the free encyclopedia
Arctocyonians (Arctocyonia; also known as "Procreodi") (from Ancient Greek ἄρκτος (árktos), meaning "bear", and κύων (kúon), meaning "dog", and thus, "bear-dog") are a clade of laurasiatherian[citation needed] mammals whose stratigraphic range runs from the Palaeocene to the Early Eocene epochs. They were among the earliest examples of major mammalian predators after the Cretaceous–Paleogene extinction event. While some classify arctocyonians as stem-artiodactyls,[1][2] others have classified the group as members of Ferae.[3] There are three families classified in the order: Arctocyonidae, Oxyclaenidae, and Quettacyonidae.
