Pliohippus stood approximately 1.25 metres, similar to the modern horse. Also like the modern horse, Pliohippus was a grazer that fed on steppe grasses of the North American plains it inhabited.

What did Pliohippus look like?

Early species still had three toes, later ones had remains of the second – and fourth toes on the outside of the remaining toe, the splint bones. The long and slender legs made Pliohippus a fleet-footed steppe animal.
