Nimravus (SciiFii)

Nimravus is a 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 7 million years. 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.
