Barbourofelidae is an extinctfamily of carnivorans of the suborder Feliformia, sometimes known as false saber-toothed cats,[2] that lived in North America, Eurasia and Africa during the Miocene epoch (22.8—7 million years ago) and existed for about 15.8 million years.[3][4] Thought to be an independent lineage from the Nimravidae and Machairodontinae, which had all attained elongated canines, recent research argues that it may be a subfamily of the Nimravidae.[5] Over the recent years, this hypothesis has been gaining more support among experts.[6]
