European cave lion and woolly rhinoceros, European cave lion, is the ancestor of the lion, the body is larger than the modern lion, the average body length of up to 2.7 meters, in the period of 300,000 to 100,000 years, the footprint of the cave lion throughout the northern and central Eurasian steppe and desert, semi-desert areas.
