Stenailurus is an extinct genus of metailurinmachairodontine (saber-toothed) cat from the Late Miocene (the Turolian, specifically) of Spain. It contains a single species, Stenailurus teilhardi . It was described based on a piece of maxilla in 1972.[1]
The generic name Stenailurus honors Bl. Niels Steensen, considered the father of paleontology, combined with the Greek αἴλουρος/ailurus meaning "cat". The specific name teilhardi honors paleontologist Pierre Teilhard de Chardin.[1]
Description
Stenailurus shows basal features of machairodonts such as the presence of a P2 tooth.[1]
In 2014, a study describing the genus Yoshi compares the morphology of teeth from multiple metailurines. Among these, the measurements of the canine teeth of Stenailurus were recorded as having a length of 44.4mm and a mesiodistal diameter of 17mm. This is mentioned to be comparable to the genera Fortunictis acerensis and Metailurus major.[2]
