Nimravidae
Nimravidae is an extinct family (biology), family of carnivorans, sometimes known as false saber-toothed cats, whose fossils are found in North America and Eurasia. Not considered to belong to the true cats (family Felidae), the nimravids are generally considered closely related and classified as a distinct family in the suborder Feliformia. Fossils have been dated from the Middle Eocene through the Late Oligocene epochs (Bartonian through Chattian stages, 41.03–25.9 million years ago), spanning about . The barbourofelids, which were formerly classified as a subfamily of the Nimravidae, were reassigned to their own distinct family Barbourofelidae in 2004. However in the 2020s, some studies suggest the barbourofelids are a branch of the nimravids, suggesting that this debate might not be settled yet. If accepted, the family would have persisted until the Late Miocene, and would extend their spatial distribution to Africa. Taxonomy The family Nimravidae was named by American pale ...

Barbourofelidae
Barbourofelidae (or Barbourofelinae) is an extinct family (biology), family (or subfamily) of carnivorans of the suborder Feliformia, sometimes known as false saber-toothed cats, that lived in North America, Eurasia and Africa during the Miocene epoch (22.8—7 million years ago) and existed for about . 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. Over the recent years, this hypothesis has been gaining more support among experts. Taxonomy The type genus, ''Barbourofelis'', was originally described by Schultz et al. (1970) and assigned to a new tribe, Barbourofelini, within the felid subfamily Machairodontinae, along with the other sabre-toothed cats. Subsequently, the tribe was reassigned to the Nimravidae by Tedford (1978) and raised to a subfamily by Bryant (1991). However, a number of studies in the early 2000s identified a closer aff ...
