How do we know what Ice Age mammals looked like? No photos or eyewitness reports exist. The mammals died out before humans developed written languages. Much of what we know comes from discoveries of fossil bones and skulls that are tens of thousands of years old.
Many of these come from Siberia, one of the coldest parts of Russia. As mammoths were buried by landslides or trapped in muddy swamps (as a result of thawing ground), they froze quickly. Mammoth remains have also been found in China, Canada, Alaska, and other areas of the United States.
