Name:
Gorgosaurus libratus
Age: Cretaceous
Formation: Judith River
Location: Montana
Size: Tooth is about 1.7 inches along curve
This is a very unusual tooth of Gorgosaurus libratus from Montana. Gorgosaurus was a large carniverous dinosaur related to Tyrannosaurus. Gorgosaurus had a huge skull with sharp, serrated teeth. This tooth is one of the few premaxillary, or''nipper'', teeth found in the very front of the jaw. Usually, carniverous dinosaur teeth have a set of serrations on each opposite cutting edge - premax teeth have both sets of serrations on only one edge, smooth on the other - better for ''nipping'' prey. The specimen has nice serrations intact, and a beautiful wear facet on the tip from use. The tooth has had some repair (normal), but no restoration. Although some of the back side of this tooth near the root is not present, this is a very good example of a front tooth from this large meat-eating dinosaur.
A Certificate of Authenticity from EXTINCTIONS is included with this specimen.
