.82" Fossil Rooted Crocodile Tooth - South Dakota

Fossil Rooted Crocodile Tooth - South Dakota #115739

This is a .82" rooted crocodile tooth from the Hell Creek Formation of Harding County, South Dakota. It is in very good condition.

Rooted teeth are fairly rare as that means they were lost from the skull after the animal died, not shed during its lifetime.

Because of its age and sedimentary composition, the Hell Creek Formation has become one of the most paleontologically studied areas in the world. 158 genera of animals and 64 genera of plants are known from the formation and new discoveries are made frequently. In addition to Tyrannosaurs, Ceratopsids, and Hadrosaurs, the formation has yielded remains of amphibians, reptiles, lizards, snakes and turtles, fish and sharks, avian and non-avian dinosaurs, and mammals. The Hell Creek Formation gives the most complete understanding of the environment just before the Cretaceous-Paleogene extinction.
