Ice-Age Tooth in a Pile of Dirt

6-year-old Julian Gagnon was visiting Michigan’s Dinosaur Hill Nature Preserve, when he found a fossilized mastodon tooth. The park was named Dinosaur Hill, because excess dirt was piled into the shape of a sleeping dinosaur, when surrounding neighborhoods were built. The 12,000-year-old tooth was a completely unexpected discovery! Julian donated it to a museum.
