Chalicotherium

A genus of extinct perissodactyls in the family Chalicotheriidae. The genus is known from Europe and Asia from the Early Miocene to Late Miocene, 23.0~5.3 million years ago. Chalicotherium, like many members of Perissodactyla, was adapted to browsing, though the chalicotheres were uniquely adapted to do so among ungulates. Its arms were long and heavily clawed, allowing them to walk on their knuckles only. The arms were used to reach for the branches of large trees and bring them close to its long head to strip them clean of leaves. The horse-like head itself shows adaptation to a diet of soft vegetation... (Wikipedia)

It's "Draw a Centaur Day" by @centaurcentral and I kinda got into a speculative biology thing on what their equivalents of non-human primates would be for the "traditional", intelligent centaurs, with the assumption they evolved naturally in the setting from a clade of six-limbed ungulates or ungulate-equivalents with specialized forelimbs.

Chalicotherium!
