.67" Fossil Nodosaurid (Denversaurus) Tooth - Montana

About Denversaurus

Denversaurus was a panoplosaurin nodosaurid dinosaur from the late Cretaceous, approximately 66 million years ago. Denversaurus was an herbivore like other nodosaurids/ankylosaurids, and measured approximately 20 feet (6 meters) on average. It lived in North America in the midwest alongside more well-known contemporaries such as Tyrannosaurus rex, Triceratops, and Pachycephalosaurus. Like other nodosaurids/ankylosaurids, it had an armored carapace made up of bony scutes all along the dorsal surface of its body.

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.
