Panthera fossilis
Panthera fossilis, also known as Panthera leo fossilis and Panthera spelaea fossilis, is an extinct species of felid belonging to the genus Panthera known from fossil remains found in Eurasia spanning the Middle Pleistocene and possibly into the Early Pleistocene. Although often historically considered a subspecies of the living lion (Panthera leo), Panthera fossilis is currently considered either a distinct species that is ancestral to, or a chronosubspecies of, Panthera spelaea (with both P. fossilis and P. spelaea having the common name "cave lion").
