Analysis of skulls and mandibles of the fossil Beringian lion demonstrate that the small lion that inhabited Yakutia (Russia), Alaska (USA), and the Yukon Territory (Canada) is a new subspecies described here as Panthera spelaea vereshchagini n. subsp. It differs from the European cave lion P. spelaea (terra typica: Gailenreuth Cave, Germany, Late Pleistocene) by its smaller size and from the American lion P. atrox (terra typica: Natchez, Mississippi, Late Pleistocene) by smaller size and by skull proportions.
