see text Dichobunidae is an extinct family of basal artiodactyl mammals from the early Eocene to late Oligocene of North America, Europe, and Asia.

They were small animals, averaging about the size of a modern rabbit, and had many primitive features.

They had complete sets of teeth, unlike most later artiodactyls, with their more specialist dentitions.

[1] The shape of the teeth suggests they were browsers, feeding on small leaves, perhaps in the forest undergrowth.

The shape of their bodies and limbs suggests they would have been fast-running animals, unlike most of their contemporaries.
