Nimravus is an extinct genus of "false" saber-toothed cat that lived in North America, Asia and Europe during the late Eocene and Oligocene epochs 35.3—26.3 mya,[1] existing for approximately 9 million years.

Not closely related to true saber-toothed cats, they evolved a similar form through parallel evolution.

With its sleek body, it may have resembled the modern caracal, although it had a longer back and more dog-like feet with partially retractile claws.

[2] A Nimravus skull, found in North America, had been pierced in the forehead region, the hole exactly matching the dimensions of the sabre-like canine of Eusmilus.

This particular individual of Nimravus apparently survived this encounter, as the wound showed signs of healing.
