Eusmilus bidentatus

Eusmilus ('true saber') is a prehistoric genus of the family Nimravidae, subfamily Nimravinae endemic to North America, Europe, and Asia during the Late Eocene-Early Oligocene epochs (37.2-28.4 million years ago), existing for approximately 8.8 million years. Eusmilus had a long body and was about as tall as a leopard. It had developed long saber teeth and looked like a saber-toothed cat, but was actually a so-called 'false saber-tooth'. Most were leopard-sized and rather long-bodied and short-legged compared to modern leopards. Some reached 2 metres long. A single specimen was examined by Legendre and Roth for body mass and was estimated to have a weight of 50 kg.
