Hypohippus

[2] It was the largest anchitherine equid about the size of a modern domestic horse, at 403–600 kg (888–1,323 lb)[3][4] and 1.8 m (5.9 ft) long.

It was a long-necked, high-shouldered browser with sub-hypsodont, lophodont (rhino-like) dentition, that fed on the tough vegetation of forest understory and shrubs.

Its deep preorbital fossae and retraction of the nasal notch hint at the presence of a long, muscular and prehensile upper lip that would aid during selective browsing.

Overall its ecology would have been more comparable to modern okapi than to grazing horses.
