Armored Ankylosaur Tooth - Two Medicine Formation

This is a nicely preserved Ankylosaur tooth from the Two Medicine Formation (Judith River Group) of Montana. It exhibits relatively little wear and is nicely preserved. It comes in a small acrylic case.

Ankylosaurs were herbivorous dinosaurs that lived during the Cretaceous and evolved complete body armor covered in plates, scutes and spikes. They wielded a massive tail club which could have been used to defensive purposes against predators such as Tyrannosaurids. Adult Ankylosaurs are believed to have reached up to 25 feet in length.
