Cretaceous Fossil Turtle Shell Sections - Hell Creek Formation

These are sections of fossil turtle shell, collected from the Late Cretaceous-aged Hell Creek Formation, making them approximately 66 million years old. The specimens come from either Montana, Wyoming, North Dakota, or South Dakota. The majority of the shell sections range from 1" to 3" wide, with some even larger. The photos are representative of the specimen(s) you will receive.

Each specimen is accompanied by a description card. Quantity discounts are available.

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.
