Entelodonts were covered briefly on Tet Zoo back in July 2007 (here), when life was oh so different. Here's a brand-new rendition of Entelodon from the Late Eocene and Early Oligocene of western Europe, Kazakhstan, China, Mongolia and Japan (it's probably the most widely distributed entelodont), kindly provided by Jaime Chirinos of zooartistica.com and used with permission.

Closely related to Late Eocene-Oligocene Archaeotherium from North America, Entelodon was a large entelodont, with good remains of E. deguilhemi from France showing that it reached 1.3 m at the shoulder, and 65 cm in skull length. Archaeotherium and Entelodon had shallower skulls than the more familiar, gigantic entelodont of the Late Oligocene and Miocene, Daeodon (aka Dinohyus: it reached 1.8 m at the shoulder), but they would still have been formidable predators and scavengers. In the illustration here they're feeding on a dead horse.

Jaime's work has appeared on Tet Zoo before: see the Thylacoleo restoration used here. Anyway, back to work. Crypto-pinnipeds, don't you know.
