Panthera onca mesembrina is an extinct subspecies of the jaguar that was endemic to North and South America during the Pleistocene epoch (1.8 mya–11,000 years ago).[3] The fossils of this large felid from late Pleistocene localities in southern Chile and Argentina, have been reported in 2017 to be remains of the American lion, Panthera atrox.[4]

Morphology

Two specimens were examined by Legendre and Roth for body mass The first specimen was estimated to have a weight of 46.3 kg (100 lb). The second was estimated to have a weight of 129.1 kg (280 lb).[5]

Fossil distribution

Fossils have been uncovered from Cueva del Milodon, Chile, Piaui, Brazil, and north to Adams County, Washington.[6]
