Notochoerus

Notochoerus is an extinct genus of very large pigs from the subfamily Tetraconodontinae. Fossils have been found in Africa, notably Uganda and Ethiopia.

Description
Notochoerus were among the largest pigs ever, with adults weighing up to 450 kg. These pigs were likely derived from the genus Nyanzachoerus. Like other tetraconodontine pigs, the males had ornamental growths on their skulls, formed from enamel.
