Barbourofelidae (or Barbourofelinae) is an extinct family (or subfamily) of of the suborder Feliformia, sometimes known as false saber-toothed cats, that lived in North America, Eurasia and Africa during the Miocene epoch (22.8—7 million years ago) and existed for about . Thought to be an independent lineage from the Nimravidae and Machairodontinae, which had all attained elongated canines, recent research argues that it may be a subfamily of the Nimravidae. Over the recent years, this hypothesis has been gaining more support among experts.
Barbourofelids first appear in the fossil record in the Early Miocene of Africa. By the end of the Early Miocene, a land bridge had opened between Africa and Eurasia, allowing for a exchange between the two continents. Barbourofelids migrated at least three times from Africa to Europe. While the genus Sansanosmilus evolved in Europe, A. jourdani also migrated through Eurasia and reached North America by the late Miocene, represented there by the genus Barbourofelis and the North American species Albanosmilus.
A further two species of Sansanosmilus ( S. rhomboidalis and S. serratus) were described by G.E. Pilgrim in 1932 based on fragmentary fossils from the Siwaliks, and a third species from the same area and of similarly fragmentary nature, Sivasmilus copei, was described by Miklos Kretzoi in 1929. Sansanosmilus rhomboidalis was described further, with new material assigned, in 2022.
A much older species, Oriensmilus liupanensis, was described in 2020. Unlike other older barbourofelids, it was found in China.
Another species of Afrosmilini from Africa, Jinomrefu lakwanza, was described in 2020 as well. Further research into the relations of Afrosmilini was published in 2021; along with assigning new material to various species, it described an unusual specimen (FT3366, a p4) from Fort Ternan that could not be assigned to any genus, and suggested the Ginsburgsmilus was also part of Afrosmilini.
