Nimravus

Nimravus is an extinct genus of "false" saber-toothed cat in the family Nimravidae, that was endemic to North America during the Oligocene epoch 33.3—26.3 mya, existing for approximately . Not closely related to true saber-toothed cats, they evolved a similar form through parallel evolution. Fossils have been uncovered in the western U.S. from Oregon to southern California and Nebraska.
Description.
"Nimravus" was around in body length. 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. It probably hunted birds and small mammals, ambushing them like modern cats, rather than chasing them down. "Nimravus" competed with other false sabre-tooths such as "Hoplophoneus".
Pathology.
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. Another "Nimravus" fossil from Nebraska was described in 1959 by paleontologist Loren Toohey, and comprises a "Nimravus" skull with saber-teeth embedded into the scapula of another "Nimravus", indicating a fatal incidence of intra-specific combat.
