T. rex Tooth Fragments in Riker Box — Hell Creek Formation, North Dakota (66 MYA)

Own a real piece of T. rex. This authentic Tyrannosaurus rex tooth fragment was recovered from the Hell Creek Formation of North Dakota and dates to the Late Cretaceous, about 66 million years ago. It comes displayed in a labeled Riker box, ready for a shelf, desk or classroom.

Each fragment is unique. The photo is an example only. The actual fragment you receive will differ, but will be of similar size and quality. Size, shape and color vary from piece to piece.

Though small, each fragment once formed part of the massive, serrated teeth that gave T. rex its legendary bite, with an estimated bite force of up to about 12,000 pounds, strong enough to crush bone. Every fragment is a tangible piece of prehistoric history from one of Earth's most fearsome carnivores.

A great gift for fossil collectors, dinosaur fans, kids, teachers, homeschoolers and anyone who wants a real T. rex fossil at an accessible price.
