About Pristinailurus
Pristinailurus bristoli is a fossil species in the carnivoran family Ailuridae. It is well-represented in the Hemphillian-aged deposits at the Gray Fossil Site in Gray, Tennessee. It was significantly larger than the living Ailurus, but probably possessed a comparatively weaker bite. P. bristoli was sexually dimorphic, as males appeared to have been up to twice the size of females.
