Keratocephalus moloch, known from a number of greatly variable skulls, along with postcrania, from the Lower and Middle Tapinocephalus zone, shows considerable variability in the pachyostoticdevelopment. It may be not as derived as Tapinocephalus. The naso-frontal boss is raised into a sort of horn and the length of the snout varies greatly. This in itself throwsdoubt on Boonstra's distinction between short and long-snouted forms. Pelosuchus, known only on the basis of postcranial features, is a synonym of this genus.
