The woolly mammoth was a large, elephant-like creature that roamed the cold tundras of the northern hemisphere during the last Ice Age. It was covered in long, shaggy hair and had a hump of fat on its back to help it survive in frigid temperatures. Woolly mammoths could grow up to 13 feet tall and weighed around 6 tons. These mammals primarily fed on grasses, shrubs, and other vegetation. They lived in herds and were known for their long, curved tusks, which they used for foraging and fighting. The woolly mammoth went extinct about 4,000 years ago, likely due to a combination of climate change and hunting by early humans.
