Pleiolama mckennai

Pleiolama mckennai is an extinct species of camelid, a member of the family Camelidae in the genus Pleiolama. It was named by Webb and Meachen in 2004, 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 Serravallian to the Tortonian stage of the middle Miocene, between about 12.5 and 9.4 million years ago, from one fossil occurrence, found in the United States (Nebraska). 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 Pleiolama mckennai as an accepted species of the family Camelidae, which is the second source for the name.
