Huge, 2.40" Serrated Tyrannosaur (Nanotyrannus) Tooth - Montana

This is a huge, 2.40" long tyrannosaur tooth from the genus Nanotyrannus, collected from the Hell Creek Formation in Montana. Typically a tooth of this length would be considered to be from Tyrannosaurus rex, however the cross section is far too thin to be rex. There are several repaired cracks and areas of gap fill throughout the crown, but the tooth retains visible serrations and offers an affordable opportunity to own a genuine specimen from this intriguing tyrannosaur.

The tooth comes with a riker mount display case.

The restoration makes up approximately 35-40% of this tooth, and can be easily identified under shortwave UV light. Upon request we can send photos of the restoration. If interested, please contact support@fossilera.com.

About Nanotyrannus

Nanotyrannus is a controversial theropod dinosaur from the Late Cretaceous of North America, known from a small number of fossils including the famous skull “Jane.” It was a relatively small, lightly built predator—about 15–20 feet long—with long legs, a narrow snout, and sharp teeth, suggesting speed and agility compared to the massive Tyrannosaurus rex. What makes Nanotyrannus especially intriguing is the debate over whether it represents a distinct genus or is simply a juvenile T. rex, with differences in skull shape, tooth count, and bone structure fueling ongoing discussion among paleontologists.


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.
