1.57" Juvenile Tyrannosaur Premax Tooth - Partial Root!

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.


The Hell Creek Formation

Renowned for both its age and rich sedimentary layers, the Hell Creek Formation is one of the most intensively studied fossil-bearing regions on Earth. To date, scientists have documented 158 genera of animals and 64 genera of plants from its rocks, with new finds emerging regularly. Beyond iconic dinosaurs such as tyrannosaurs, ceratopsians, and hadrosaurs, the formation has produced an extraordinary array of life, including amphibians, reptiles, lizards, snakes, turtles, fish, sharks, birds, and early mammals. Together, these fossils provide the most complete picture of the ecosystems that thrived just before the Cretaceous–Paleogene extinction event.
