† American lion [25] [26] [27] † Panthera atrox: At least 80 individuals A large pantherine, the American lion is a possible descendent of Eurasian cave lions that had become isolated in North America. [26] This big cat is found much more rarely than the contemporary Smilodon. Within the species itself, more fossil specimens are thought to ...
Panthera atrox: North America, 0.13 to 0.013 MYA, with dubious remains in South America. [63] Commonly known as the American lion, P. atrox is thought to have descended from a basal P. spelaea cave lion population isolated south of the Cordilleran Ice Sheet, and then established a mitochondrial sister clade circa 200,000 BP. [64]
Panthera spelaea lived in Europe after the third Cromerian interglacial stage from about 450,000 to 14,000 years ago. [13] Panthera atrox lived in North America during the Pleistocene and early Holocene about 340,000 to 11,000 years ago. [14] Panthera shawi was a lion-like cat in South Africa that possibly lived in the early Pleistocene. [15]
The heaviest known pantherine felids are the Ngangdong tiger (Panthera tigris soloensis), which has been estimated to have weighed up to 486 kg (1,071 lb), [181] the extinct leonine Panthera fossilis, which has been estimated to have maximum weight of 400–500 kg (880–1,100 lb), [187] the American lion (Panthera atrox), weighing up to 363 kg ...
