Panthera leo vereshchagini, also known as the East Siberian and Beringian cave lion, was a small fossil lion that inhabited Yakutia (Russia), Alaska (USA), and the Yukon Territory (Canada). Analysis of skulls and mandibles of this lion demonstrate that it is a new subspecies different from the other prehistoric lions. It differs from the European cave lion (Panthera leo spelaea) by its larger size and from the North American cave lion (Panthera leo atrox) by its smaller size and by skull proportions.^[1][2] Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms (as opposed to folk taxonomy). ...
