.55" Rooted Fossil Ankylosaur Tooth - Montana

This is a partially rooted, .55" tooth from an indeterminate ankylosaur. It was collected from the Two Medicine Formation in Montana. Not enough diagnostic material has been uncovered and studied from this formation for identification down to the species level. Comes in an acrylic display 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 Tyrannosaurs. Adult Ankylosaurs are believed to have reached up to 25 feet in length.
