Epihippus jaw
Epihippus is believed to have evolved from Orohippus, which continued the evolutionary trend of increasingly efficient grinding teeth. Epihippus had five grinding, low-crowned cheek teeth with well-formed crests. A late species of Epihippus, sometimes referred to as Duchesnehippus intermedius, had teeth similar to Oligocene equids, although slightly less developed. Whether Duchesnehippus was a subgenus of Epihippus or a distinct genus is disputed. This is an early species of a horse.
