Coryphodon Mammal Fossil Incisor Tooth Eocene Willwood Formation WY Eocene
- Source: eBay
The fossil, approximatly 50 million years old, was found on the surface of the Willwood Formation near Worland, Wyoming. An incisor tooth with almost perfect enamel. My father and I hunted these fossils in the 1960's and this specimen is part of the collection. Coryphodon was a pantodont, a member of the worlds first group of large browsing mammals.
