Home > Nimravidae
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 .
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.
