This book tells the story of the Woolly Mammoth, an animal that lived during the last Ice Age. Its long outer hair and inner layer of wool helped it withstand the bitterly cold conditions. Huge curved tusks were used to dig for food under the snow and as a powerful weapon against enemies. The Woolly Mammoth weighed up to six-and-a-half tons (six metric tons) and stood ten feet (three meters) tall.
