Oxydactylus longipes

Oxydactylus longipes is an extinct species of camelid, a member of the family Camelidae in the genus Oxydactylus. It was named by Peterson in 1904, and the Paleobiology Database records it as an extinct species of the order Artiodactyla, the even-toed ungulates. The database dates the species from the Chattian to the Serravallian stage of the late Oligocene, between about 23.1 and 11.63 million years ago, from 5 fossil occurrences, found in Mexico (Baja California) and the United States (Nebraska, Wyoming). Its ecospace record gives a terrestrial, ground-dwelling way of life and a browsing or grazing diet, values taken from the wider family, since fossils of the species itself do not show how it fed. The GBIF backbone taxonomy lists Oxydactylus longipes as an accepted species of the family Camelidae, which is the second source for the name.
