Anchitherium (meaning near beast) was a fossil horse with a three-toed hoof.

Anchitherium was a browsing (leaf eating) horse that originated in the early Miocene of North America and subsequently dispersed to Europe and Asia,[3][4] where it gave rise to the larger bodied genus Sinohippus.

[1] It was around 60 centimetres (6.0 hands) high at the shoulder, and probably represented a side-branch of horse evolution that left no modern descendants.
