Mammoths are relatives of the elephants of today. They were alive in the Cenozoic Era-Age of Mammals. Woolly Mammoths have long trunks and very long hair. What you probably didn't know even though Woolly Mammoths are huge they have small ears and were herbivores. Mammoths used their trunks to hold things like their babies. Some people might think they look a little odd but I think they were cool. From the hump on their head to their extremely long tusks to their fur that was covered in fat, these magnificent creatures of the Ice Age were a once in a lifetime creation.
