American lion

The American lion (Panthera atrox) is a pantherine cat that lived in North America during the Pleistocene epoch about 340,000 to 11,000 years ago.[2][3][4] Its fossils have been excavated from Alaska to Mexico.[5][6] Genetic analysis has shown that the American lion and the Late Pleistocene Eurasian cave lion (Panthera spelaea) are sister lineages.[7] It was about 25% larger than the modern lion, making it one of the largest known felids.[8]
