Entelodon
Entelodon
(meaning "complete teeth", from Ancient Greek ἐντελής entelēs "complete" and ὀδών odōn "tooth", referring to its "complete" eutherian dentition[1]), is an extinct genus of entelodont artiodactyl endemic to Eurasia. Fossils of species are found in Paleogene strata ranging in age from the Houldjinian (37.2–33.9 mya) until the Rupelian epoch of the early Oligocene (33.9–28.4 mya).[2]

Size comparison between E. deguilhemi and a human

Entelodon
Entelodon
was a fairly typical entelodont, with a large, bulky body, slender legs, and a long snout. Like other entelodonts, Entelodon
Entelodon
had complete eutherian dentition (3 incisors, 1 canine, 3 premolars, and 3 molars per quadrant). It had only two toes on each foot, and its legs were built for fast running.[3] Its long, wide head was supported by a robust, short neck,[3] and its cheekbones were greatly enlarged and protruded noticeably from the sides of the head.[4] Though it was more closely related to hippos and whales than pigs, its skull was generally pig-like.[3][4] It is presumed to have been an omnivore. Entelodon
Entelodon
was around 1.35 metres (4 ft 5 in) tall at the shoulders, with a 65 centimetres (26 in) skull.[3] Paleoecology[edit]

Entelodon
Entelodon
remains are primarily known from Europe, although one Entelodon
Entelodon
specimen was found as far as northern China. Entelodon
Entelodon
magnus populated a broad swath of Europe, with remains found in Spain, Germany, France, Romania, and the Caucasus. Extensive remains of Entelodon
Entelodon
deguilhemi were uncovered in Vayres-sur-Essonne, France.[3][5] The Chinese Entelodon
Entelodon
dirus is known from a single tooth discovered in Nei Mongol.[6] In popular culture[edit] Entelodon
Entelodon
was featured in the third episode of the popular BBC documentary Walking with Beasts. In the program, the narrator always calls the creatures "Entelodonts", instead of the specific genus name.[7]
