.45" Fossil Nodosaurid Tooth - Oldman Formation, Montana

Fossil Nodosaurid Tooth - Oldman Formation, Montana #302525

This is a .45" long partial tooth of a nodosaurid, collected from the Late Cretaceous-aged Oldman Formation (Judith River Group) in the Mile River area of Northern Montana. There are yet to be any formally described nodosaurids out of this formation, therefore we have labelled it as nodosaurid indet.

Comes with an acrylic display case.

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.
