1.34" Tyrannosaurus Rex Tooth

This is a 1.34" long tooth from Tyrannosaurus rex (T-Rex) the king of the dinosaurs. It's not one of the much more common, more slender teeth that typically gets attributed to Nanotyrannus. The tooth is nice and robust with good coloration and has no restoration or repair.

This tooth was found at a private ranch in Butte County, South Dakota earlier this summer. It comes from a quarry known as the "Tooth Draw Quarry" that has produced many high quality dinosaur teeth over the past several decades. In the Late Cretaceous some 65 million years ago, this quarry was located in a sub-tropical floodplain that would have been similar to modern day coastal Louisiana. It consists of 2 meters of alternating sandstone and gravel, representing a river channel lag deposit. It contains many isolated dinosaur teeth including T-Rex, Nanotyrannus, Raptors and Triceratops, but teeth of this high quality are rare finds.
