Nyanzachoerus is an extinct genus of the pig family (Suidae) belonging to the subfamily Tetraconodontinae. The several species of Nyanzachoerus lived in Africa from the Miocene to Pliocene.[1][2]


This was a large pig, larger than living species.

Fossils of males of these species show that they had large lumps on their muzzle and widely flaring cheekbones. Their tusks were only of moderate size. It can be assumed that the ornaments were used as a mating display.

It may have been preyed on by the giant mustelid Ekorus


A total of 8 species have been described.[3]
