Panthera atrox (Leidy, 1853)

American lion

 

 

Taxonomy & Nomenclature

Synonym/s: Felis atrox Leidy, 1853 (original combination); Felis imperialis Leidy, 1853; Felis atrox bebbi Merriam, 1909; Felis atrox alaskensis Frick, 1930; Panthera jaguarius atrox Leidy, 1853; Panthera leo atrox Leidy, 1853

 

Conservation Status

Extinct

Last record: Late Pleistocene

 

There have been numerous reports of lions or lion-like animals in America during the 20th century (Coleman, 1971; Bord & Bord, 1989:231-232). And cryptozoologist Loren Coleman has hypothesized that these may refer to surviving individuals of the American lion ([i]Panthera atrox[/i]) (Coleman, 1983:106-116). However, [i]P. atrox[/i] is probably more closely related to the Jaguar ([i]P. onca[/i]) than to the [i]bona fide[/i] Afro-Eurasian lions ([i]P. leo[/i] ssp.).

 

Distribution

The Americas (North, Central and South America)

 

Remains of Panthera from South America have been known since the late 19th century, however they were only recognised as belonging to the American 'lion' extremely recently (Chimento & Agnolin, In Press). It may have had reddish skin (Ibid.).
