Mastodon jaw bone fossil. Part of the fossilised jaw bone of a mastodon, including some teeth. The mastodon (Mammut sp.) lived from 20 million years ago to about 10,000 years ago. It was an elephant- like animal, part of the megafauna (large animals) of prehistoric times that became extinct. The blunt, conical shape of its teeth made a mastodon more suited to chewing leaves, than grazing grass like the mammoth. The name mastodon (it is also called mastodont) means 'mastoid (nipple) tooth'.
