1.9" Tyrannosaur Tooth in Rock With Display Stand - Montana
This is a 1.9" Tyrannosaur tooth in sandstone that was collected from the Two Medicine Formation of Montana. The tooth has been removed from the sandstone, repaired and then remounted back into the sandstone from which it was found. The repair work consists of one repaired crack about a half an inch from the tip of the tooth. There is some natural stress fracturing that runs along the length of the tooth, as well as some chipping away of enamel from the tip. The serrations are still present and in overall good condition. The tip of the tooth is feeding worn and the sandstone around the tooth has been stabilized with glue to ensure structural integrity of the entire specimen.
This specimen comes with a custom built metal stand.

Three species of tyrannosaur have been described from the Two Medicine & Judith River Formations: Albertosaurus, Gorgosaurus and Daspletosaurus. Research done on teeth from these three tyrannosaurs has concluded that isolated teeth are statistically impossible to assign to a specific genus because they are so similar.

About The Two Medicine Formation
The Two Medicine Formation is a geographical formation in Central Montana and Southern Alberta, Canada. The formation is predominantly sandstone laid down by rivers and deltas during the Campanian Age of the Cretaceous, about 80-75 million years ago. Approximately two thousand feet thick on the western edge, it lies on top of the Virgelle Sandstone formation and under the Bearpaw Shale. It is located between the Front Range of the Rocky Mountains and the Sweetgrass Arch, a tectonic fold feature 40-90 miles east of the Front Range.
The Two Medicine is the same age as the Judith River Formation found further east. It was laid down further inland from the Western Interior Seaway, while the Judith River Formation was deposited along the coast. The Two Medicine contains much of the same dinosaur fauna, but fewer reptiles, amphibians, and aquatic fossils.
