1.9" Dinosaur Jaw Section - Montana

This is a jaw section of a dinosaur that was collected from the Hell Creek Formation of Garfield County, Montana. You can see the grooves where the dinosaur's teeth would have been. Due to the lack of bone present, it's nearly impossible to provide an accurate species, let alone type of dinosaur.

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.
