anisodon

Anisodon grande, a large chalicothere from the Late Miocene of Europe, about 15 million years ago. Standing 1.5m tall at the shoulder (4′11″), it looked somewhat like a cross between a gorilla, a horse, and a giant sloth – or like a mammal trying to mimic a therizinosaur. Its long forelimbs were probably used to pull down high tree branches so it could browse on the leaves, while spending most of its time sitting on its well-padded haunches.

Despite its huge claws, knuckle-walking gait, and distinct lack of hooves, it was actually an odd-toed ungulate related to modern horses, rhinos, and tapirs.
