Distribution

Most fossils have been found in Fayum, Egypt, but one species, B. orientalis, is known from Late Eocene deposits in Thailand. It is believed to have originated from the Asian genus Anthracokeryx.[2] Bothriogenys is believed to be one of the first anthracotheriids to have entered Africa.[3]

Description

In life, they would have resembled hippopotamuses with small, elongated heads.

Palaeobiology

Growth and development

The deciduous premolars in the mandible of B. fraasi were retained all the way until the third mandibular molar began developing in the crypt, in contrast to the modern hippopotamus that sheds all deciduous premolars by the time its M3 develops in the crypt.[4]
