Protolabis notiochorinos

Protolabis notiochorinos is an extinct species of camelid, a member of the family Camelidae in the genus Protolabis. The Paleobiology Database credits the name to Patton in 1969, while the GBIF backbone taxonomy gives Patton and the year 1976, and the database dates the species from the Aquitanian stage of the early Miocene to the Messinian stage of the late Miocene, between about 23 and 5.3 million years ago, from 12 fossil occurrences in Arizona, Nevada and Texas in the United States. The Paleobiology Database lists it as an extinct member of the even-toed ungulates with a terrestrial, ground-dwelling way of life and a browsing diet, values it takes from the wider group, and it files the name as a synonym of Protolabis coartatus, whereas the GBIF backbone lists it as an accepted species, so the two sources disagree about whether it stands apart from that species.
