similar to the archaeopteryx fossil. Were all mammoths woolly?
The mammoth had to grow a woolly coat when the world began to get colder, about 700,000 years ago. But by the end of the Ice Age, even the woolly mammoth was extinct. The only survivor was the dwarf mammoth, which died out about 3,500 years ago. Some people believe that woolly mammoths survived the Ice Age, but died from disease or were hunted down for food.
