Coryphodon incisor
Willwood Formation of Wyoming
Eocene Age (56 to 33.9 million years ago)
The tooth with the root sits 7/8" tall and measures approximately 5/8" across the bottom. Coryphodon (from Greek "point", and "tooth", meaning peaked tooth, referring to "the development of the angles of the ridges into points [on the molars].") is an extinct genus of mammal. Coryphodon was a pantodont, a member of the world's first group of large browsing mammals. It migrated across what is now northern North America, replacing Barylambda, an earlier pantodont. It is regarded as the ancestor of the genus Hypercoryphodon of Mid Eocene Mongolia. Coryphodon is known from many specimens in North America and considerably fewer in Europe, Mongolia, and China. It is a small to medium-sized coryphodontid who differs from other members of the family in dental characteristics. Coryphodon had one of the smallest brain/body ratios of any mammal, living or extinct, possessing a brain weighing just 90 grams (3.2 oz) and a body weight of around 500 kilograms (1,100 lb).
