Woolly Mammoth (2,000 B.C.)

The Woolly Mammoth (Mammuthus primigenius) inhabited much of the arctic tundra regions of the northern hemisphere in the early Holocene period. These massive creatures could reach 11 feet in height and weigh six tonnes, which is about the same size as African elephants, though their closest relative is the Asian elephant. However, unlike the elephant, it was covered in brown, black, and ginger fur. It also had a shortened tail to minimize frostbite.
