This mastodon tooth, weighing about 5 pounds, was found in the early 1950s in the remote Alaskan wilderness by T. Casey Moher, (later Dover City Attorney and District Court justice), during a Korean War winter survival training course. Mastodons were large, hairy, vegetarian ancestors of the modern elephant and roamed all of North America from 33,000 years ago until their mass extinction from human hunting about 10,000 years ago. They were 7’ to 9’ tall and weighed about 4-5 tons. Their high, jagged, cusp-like teeth were well suited for feeding on leaves, branches, trees, and other woody plants. The tooth was donated to the Museum after Moher’s death in 2004.
