Nano Tyrannosaur tooth

This is a .98" long tyrannosaur tooth from the genus Nanotyrannus, collected from the Hell Creek Formation in Montana. The enamel is weathered across the majority of the crown, though small areas of serrations remained preserved along both edges.

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 tooth comes with a small acrylic display case.
