Pristinailurus bristoli is a fossil species in the carnivoran family Ailuridae, well-represented in the Hemphillian deposits of Gray, Tennessee.[1] It was significantly larger than the living Ailurus but probably possessed a weaker bite. Males appear to have been as much as twice the size of females.[2]

Temporal range: Miocene–Pliocene
