Description

Reconstructed faces of male (left) and female (right) Archaeotherium mortoniEntelodonts possessed characteristic bony protrusions on their skulls and mandibles, which are notably larger and broader in mature male specimens. The only modern mammals which possess facial growths analagous to those of entelodonts are certain types of pigs, such as warthogs (Phacochoerus). These "warts" are are sexually dimorphic features that act as shields protecting the eyes from damage during intraspecific fights. goo.gl/Jykw2s
