About Epihippus
Epihippus is an extinct genus of the modern horse family Equidae that lived in the Eocene, from 46 to 38 million years ago.
Epihippus is believed to have evolved from Orohippus, which continued the evolutionary trend of increasingly efficient grinding teeth. It had five grinding, low-crowned cheek teeth with well-formed crests. A late and partially recognized species of Epihippus, sometimes called Duchesnehippus intermedius, had teeth similar to Oligocene equids, although slightly less developed. The genus fed mostly on insects, berries and plant material.
