Protolabis barstowensis

Protolabis barstowensis is an extinct species of camelid, a member of the family Camelidae in the genus Protolabis. It was named by Lewis in 1968, 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 Burdigalian to the Serravallian stage of the early Miocene, between about 16.3 and 12.5 million years ago, from one fossil occurrence, found in the United States (California). 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 Protolabis barstowensis as an accepted species of the family Camelidae, which is the second source for the name.
