Originally described as a species of Dicynodon, Aulacephalodon is a genus of dicynodont therapsid that lived in Southern Africa towards the end of the Permian. At around one and a half meters long, Aulacephalodon was mid-sized for the type of animal that it was, and like its relatives, Aulacephalodon is known to have had a tough beak like mouth as well as two downwards facing tusks. The type species A. bainii was named in 1898 by Harry Govier Seeley, and twenty three years later a second species A. peavoti was named by Robert Broom. The validity of this second species has now been questioned (Govender 2008), with the notion that the species A. peavoti may not actually belong to the genus.
