Brachyhyops is an artiodactyl which has a poorly resolved evolutionary status that continues to be subject of revision. Colbert initially classified Brachyhyops strictly within the bunodontids based on its bunodont-like tooth shape. More recent studies revised the evolutionary relationship of Brachyhyops and it has now been recognized as a very basal entelodontid that might represent the origin of the clade Entelodontidae,Foss, S.E. (2007). Family Entelodontidae. In, Prothero, D. R. and Foss, S. E. eds.,The Evolution of Artiodactyls, p. 120–129.
