Nimravinae

The Nimravinae are a subfamily of the Nimravidae, an extinctfamily of feliformmammaliancarnivores, sometimes known as false saber-toothed cats. They were found in Eurasia and North America from the Late Eocene through the Late Oligocene epochs (Bartonian through Chattian stages, 35.37—25.9 mya), spanning about 17.37 million years. Centered in North America, the radiation of the Nimravinae from the Eocene to Oligocene was the first radiation of cat-like carnivorans. This subfamily would later disperse into Africa and gave rise to Barbourofelinae.
