Nimravinae
Hoplophoninae
Barbourofelinae
The Nimravidae, also known as false sabre-tooths, are an extinct family of mammalian carnivores. Although they physically resembled the sabre-toothed cats (Smilodon), they were not closely related, but evolved a similar form through parallel evolution. It is not certain wether Barbourofelinae truly has closest affinities with Nimravids.
The ancestors of the Nimravids and cats diverged from their common ancestor in the early Eocene, more than 50 million years ago (mya). Recognizable Nimravid fossils date from the later Eocene (36 million mya) to the late Miocene (5 mya). Nimravid diversity appears to have peaked about 28 mya. Most had muscular, low-slung catlike bodies, with shorter legs and tails than typical of cats. The largest species reached the size of a lion.
