/ɔˈriəˌdɑn/

Origin: A borrowing from Latin. Etymon: Latin Oreodon.

Palaeontology.

A former genus (now included in the genus Merycoidodon) of extinct pig-sized ruminant mammals of the family Oreodontidae, having four toes on each foot and selenodont teeth, the remains of which are found in Middle Tertiary rocks in the western United States; (also) an animal of this genus. Later chiefly in Oreodon beds: strata containing fossils of these animals.

1852 Proc. Acad. Nat. Sci. Philadelphia 1850–51 5 238 Neither of these fossils Dr L[eidy] suspected belonged to Merycoidodon... For the first he proposed the name of Oreodon.

1877 J. Le Conte Elements Geol. (1879) 505 The Oreodon is another very remarkable animal, intermediate between the hog, the deer and the camel.

1893 Amer. Naturalist 27 182 These deposits were arranged in three groups, lower or Menodus beds, middle or Oreodon beds, and upper or Protoceras beds.

1923 Amer. Jrnl. Sci. 206 222 (heading) Oreodons of the lower Harrison beds.

1985 E. H. Colbert Wandering Lands & Animals (new ed.) ix. 232 The Middle and Upper Oligocene beds of the White River sequence have often been referred to as the ‘Oreodon beds,’ to distinguish them from the Lower Oligocene ‘Titanotherium beds.’
