Anteosaurids distinguished from ''Brithopus'' and other non-anteosaurid anteosaurians by the presence of a large thickened region or "boss" on the side of the angle of the lower jaw; this was probably used in intraspecific behaviour. In ''Doliosauriscus'' and ''Anteosaurus'', not only was this boss very prominent, but the bones were very thick and rugose. The same situation is found in the herbivorous Tapinocephalidae, and it has been proposed that these animals engaged in head-butting behaviour.
