Writer/Researcher: Brian Melloni Editor: Dan Lancour Web Page Builder: Brian Melloni The woolly mammoth was one of three species of the genus Mammuthus that lived on the mainland of North America during the last ice age. Other relatives of the woolly are the Colombian mammoth and Jefferson's mammoth. It was these lesser known species that first crossed the Bering Strait from Asia about 2 million years ago to populate what is now the United States and Canada. The woolly mammoth crossed the strait much later. Researchers believe that, while they existed in Eurasia far earlier, they did not migrate into North America until about 500,000 years ago.
The woolly mammoth stood 10-14 feet tall, and weighed in from 6-8 tons. The fossil record shows us that the mammoth's teeth were strong, plated enamel that was ideally suited to eat many kinds of plants including grasses, aquatic plants, and even shrub and tree material. However, during the last ice age they tended to stay within the grassy plain environment of savannas and tundras.
