Belongs within: Perissodactyla.

The Chalicotheriidae are a group of perissodactyls known from the Eocene to Pleistocene of Eurasia and North America, with a limited record from Africa. Members of this group possessed feet with large fissured claws rather than hooves and may have been upright browsers in the manner of gorillas or ground sloths.
