Hesperocamelus stylodon

Hesperocamelus stylodon is an extinct species of camelid, a member of the family Camelidae in the genus Hesperocamelus. It was named by Macdonald in 1949, 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 Aquitanian to the Messinian stage of the early Miocene, between about 23.04 and 5.333 million years ago, from 2 fossil occurrences, found in the United States (Nevada). 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 Hesperocamelus stylodon as an accepted species of the family Camelidae, which is the second source for the name.
