Study of the Creodont Patriofelis for the Eocene Scene

Roy Krenkel

[plasmagruntcalvin]

The ferocious Patriofelis may look like a cat, however it’s a member of a long extinct mammal family called oxyaenidae. This mammal was likely slower on land but could have been a good swimmer or climber.

Sarkastodon mongoliensis, an oxyaenid from the Late Eocene of Mongolia, about 35 million years ago. Known only from a skull and jawbones, it probably stood around 1m tall at the shoulder (3′3″), roughly the size of a modern brown bear. Its teeth were very hyena-like, suggesting it was a hypercarnivore specializing in bone-crushing.

Oxyaenids were traditionally classified as part of the creodonta, a wastebasket taxon, but actually seem to have been basal members of the laurasiatheres -- the branch of the mammal family tree that includes hedgehogs, shrews, bats, whales, ungulates, and carnivorans.
