Oxyaena ("Sharp" or "Drawn-out" + hyena) is an extinct genus of oxyaenid mammal from the latest Paleocene to early Eocene of North America (most specimens being found in Colorado). The species were superficially cat or wolverine-like, with a flexible body 1 metre (3.3 ft) long, and short limbs. Oxyaena had a broad, low skull (20 cm. long) with a long facial part and a massive lower jaw, while its body and tail were long and its five-toed limbs were short. Unlike true cats, Oxyaena was plantigrade, treading on the whole surface of its soles.
