N. brachyops skull with canines piercing the leg bone of another specimen
Description
Nimravus was around 1.2 metres (4 ft) 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.[2]
Pathology
A Nimravusskull, 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 humerus of another Nimravus, indicating a fatal incidence of intra-specific combat.[3]
