Fragment of a Mastodon Tooth. Mastodons were hairy elephant-like creature that browsed on leaves. This specimen measures approximately 2 by 4 inches. They went extinct around 9000 B.C. Both bones and teeth of Mastodons have been found in St. Louis. At Mastodon State Park in adjacent Jefferson County, a Paleo-Indian spear point was found associated with one Mastodon skeleton. The above was found in Florissant, Missouri by Scott Williams.
