The American lion (Panthera atrox (/ ˈ p æ n θ ər ə ˈ æ t r ɒ k s /), with the species name meaning "savage" or "cruel", also called the North American lion) is an extinct pantherine cat native to North America during the Late Pleistocene from around 130,000 to 12,800 years ago.
Panthera is a genus within the family Felidae, and one of two extant genera in the subfamily Pantherinae.It contains the largest living members of the cat family. There are five living species: the jaguar, leopard, lion, snow leopard and tiger, as well as a number of extinct species, including the cave lion and American lion.
Some authors considered it a subspecies of Panthera spelaea (Panthera spelaea fossilis) or treat it as a distinct species. [17] [18] Some employ a subgenus of Panthera, "Leo", to contain several lion-like members of Panthera, including P. leo, P. spelaea, P. atrox and P. fossilis. [10]
Panthera spelaea lived in Europe after the third Cromerian interglacial stage from about 450,000 to 14,000 years ago. [16] Panthera atrox lived in North America during the Pleistocene and early Holocene about 340,000 to 11,000 years ago. [17] Panthera shawi was a lion-like cat in South Africa that possibly lived in the early Pleistocene. [18]
†American lion (Panthera leo atrox), reported from Peru [217] and Argentina and Chile; [218] however, the former set of remains has later been identified as belonging to a jaguar [219] and the latter set of remains were initially identified as being from jaguars; Bats (Chiroptera)
Several anatomical studies of remains of Panthera spelaea were conducted during the early-mid 19th century, who generally agreed that the species had lion affinities. [4] During the 20th century and the first decade of the 21st century, Panthera spelaea was often regarded as a subspecies of the modern lion, and therefore as Panthera leo spelaea.
† 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 ...
