edit Period on Earth. The mammoth lived from the Pliocene epoch, about two million years ago, into the Holocene age. Most mammoths became extinct 10,000 years ago. Some smaller woolly mammoths, one of the species of mammoths, lived on an isolated island until 3750 BC. The mastodon pre-dated the mammoth, although there was overlap. Mastodons lived from the late Miocine era, about 5.3 million years ago to the late Pleistocene era, which ended 10,000 years ago. Mastodons became extinct 10,000 years ago. The precise reason why both species became extinct is unknown.
