1.57" Juvenile Tyrannosaur Premax Tooth - Partial Root!

Juvenile Tyrannosaur Premax Tooth - Partial Root! #245869

This is a tyrannosaur premaxillary tooth with a partial root, collected from the Hell Creek Formation of Montana. These oddly shaped teeth with two ridges located on the lingual side were originally described as Aublysodon more than a century ago based on isolated teeth and jaw fragments. More recent discoveries of more complete tyrannosaur skeletons from this formation has lead to the discovery that these teeth are actually the premaxillary teeth from juveniles of other tyrannosaur species.

The tooth is 1.57" long and likely would have come from either Tyrannosaurus rex or Nanotyrannus lancensis. There is a repaired crack between the crown and root, along with another repaired crack near the apical end of the tooth.

Comes with a floating frame display case.

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.
