.51" Rooted Nodosaur Tooth - Judith River Formation

Rooted Nodosaur Tooth - Judith River Formation #144851

This is a .51" tooth from a Nodosaur. It was collected from the Judith River Formation in Montana. While Nodosaur teeth are relatively abundant in the formation, not enough skeletal material has been recovered to describe the species.

Nodosaurs are a family of ankylosaurian dinosaurs that lived from the Late Jurassic to Late Cretaceous periods. They were medium to large-sized, quadrupedal herbivores that were heavily armored, adorned with rows of bony armor nodules and spines. Unlike ankylosaurs, nodosaurs lacked mace-like tail clubs. Nodosaurs possessed small, leaf-shaped teeth, which can be impossible to distinguish from ankylosaur teeth when heavily worn or weathered. Nodosaur teeth have a characteristic "shelf" visible below a pocket in the crown, and no center ridge.
