Dinictis (terrible cat) belonged to the Genus Nimravidae, which is an extinct family of cat-like mammalian carnivores, also known as "false saber-toothed cats." Dinictis felina was named by the American paleontologist Joseph Leidy in 1854. Dinictis is found from Canada through the central-western states down through Colorado. It existed from the Late Eocene to the Early Miocene epochs (37.2-20.4 MYA), living for about 16.8 million years.
Dinictis' body was a sleek 3.6 feet long and 2 feet high. Its claws were not completely retractable. Dinictis and other Nimravids walked flat footed (plantigrade), unlike current day cats which walk on their toes (dentigrade). It had strong jaws and a long tail. Its size and shape were similar to a close relative - Hoplophoneus. Its upper canines were relatively small, but still protruded distinctively from its mouth and the lower jaw was flared at the front sides to protect the upper canines. Dinictis' teeth were shorter and more rounded than those of Hoplophoneus and Eusmilus (whose teeth were thinner and laterally compressed), indicatiing that they were more likely to have been used to physically hold the prey while it was still struggling or to bite through the skull or spine to kill its prey. Because of its size, Dinictis would have probably been an ambush hunter, waiting for vegetarian browsers to put themselves in harms way during feeding.
Animals at the top of the food chain are usually rarer than the prey at the bottom. Their numbers were fewer and therefor their remains would be fewer. We are pleased to be able to offer several specimens from this rare species.
Also, teeth from the Nebraska and South Dakota areas will fluoresce. Be sure to look for them in the fluorescent section under teeth in the Nebraska and South Dakota pages. The item number will be the same as here, except it will be followed by an "F."
