Elomeryx is an extinct genus of artiodactyl ungulate, and is among the earliest known anthracotheres.

The genus was extremely widespread, first being found in Asia in the middle Eocene, in Europe during the latest Eocene, and having spread to North America by the early Oligocene.

[1] The closest living relatives of the Elomeryx are bovids, suids, and cetaceans.

Elomeryx was about 1.5 metres (4.9 ft) in body length, and had a long, vaguely horse-like head.

Elomeryx had five-toed hind legs and four-toed front legs, resulting in wide feet which made it easier to walk on soft mud.
