.87" Aublysodon Tooth - South Dakota

This is a .86" long Tyrannosaurid tooth which is typically assigned to Aublysodon. There is debate about whether this is actually a valid genus or rather Juvenile teeth of another type of Tyrannosaurid. This is due to the fact that Aublysodon was described based on only partial skull elements and several teeth in 1868.

It is well preserved with no restoration or repair. It comes in an acrylic display case.

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.
