Skull of Merycoidodon culbertsoni. Most researchers in paleobiology and paleontology now use the antecedent genus Merycoidodon to refer to this Oligocene epoch oreodont, even though it was once widely known by the younger synonym of Oreodon.
Entelodontidae is an extinct family of pig-like artiodactyls (even-toed ungulates) which inhabited the Northern Hemisphere (Asia, Europe, and North America) from the late Eocene [1] to the early Miocene epochs, about 38-19 million years ago.
The order Artiodactyla consists of 349 extant species belonging to 132 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 132 genera can be grouped into 23 families; these families are grouped into named suborders and many are further grouped into named clades, and some of these families are subdivided into named subfamilies.
Catodontherium is an extinct genus of Palaeogene artiodactyls belonging to the family Anoplotheriidae.It was endemic to Western Europe and had a temporal range exclusive to the middle Eocene, although its earliest appearance depends on whether C. argentonicum is truly a species of Catodontherium.
Robiatherium is an extinct genus of Palaeogene artiodactyls containing one species R. cournovense.The genus name derives from the locality of Robiac in France where some of its fossil were described plus the Greek θήρ / therium meaning "beast" or "wild animal".
Andrewsarchus (/ ˌ æ n d r uː ˈ s ɑːr k ə s /), meaning "Andrews' ruler", is an extinct genus of artiodactyl that lived during the Middle Eocene in what is now China. The genus was first described by Henry Fairfield Osborn in 1924 with the type species A. mongoliensis based on a largely complete cranium.
This diverse group of stocky prehistoric mammals grazed amid the grasslands, prairies, or savannas of North and Central America throughout much of the Cenozoic era. First appearing 48 million years ago (Mya) during the warm Eocene epoch of the Paleogene period, the oreodonts dominated the American landscape 34 to 23 Mya during the dry Oligocene epoch, but they mysteriously disappeared 4 Mya ...
