About Nanosmilus

Nanosmilus is a nimravid from the Oligocene (Whitneyan to Arikareean stages) of Nebraska. As a member of Feliformia, it is related to the superficially similar-appearing true cats. As such, it and nimravid genera in general are often referred to as false saber-toothed cats. No larger than a small bobcat, it is the smallest known saber-toothed mammal currently recognized by science. It is most closely related to its fellow nimravid Eusmilus.
