Proailurus (meaning "first cat") is an extinct carnivoran felid that lived in Europe and Asia approximately 25 million years ago in the Late Oligocene and Miocene. Fossils have been found in Mongolia, Germany, and Spain. One recent phylogeny places it as a basal member of the Feliformia, the suborder that includes mongooses, civets, hyenas, and cats; but other studies suggest that it instead was a felid (a true cat).
