Sansanosmilus

Sansanosmilus is an extinct genus of carnivorous mammal of the family Barbourofelidae (false saber-tooth cats) endemic to Europe, which lived during the Miocene, 13.65—9.7 mya, existing for approximately 3.95 million years.

[1] Sansanosmilus is a member of the family Barbourofelidae, a group of feliform carnivorans related to either felids[2] or nimravids.

In 1961, paleontologist L. Ginsburg concluded that Sansanosmilus was possessed of a plantigrade walking stance, after studying its foot bones and comparing it with those of the true felid Pseudaelurus from the same site.

[4] The type species, Sansanosmilus palmidens, is known from fossils from the Orleanian and Astaracian stages in France.

Although Albanosmilus was seen as a junior synonym of Sansanosmilus from the 1970s onwards, Robles et al. (2013) demonstrated that the type species of Albanosmilus, S. jourdani (which they considered to be a senior synonym of S. vallesiensis), is more closely related to Barbourofelis than to the type species of Sansanosmilus and thus generically distinct.
