This is a tooth from a large Gorgosaurus. This specimen is from Montana. Gorgosaurus was one of the last carniverous dinosaurs. This large tooth is quite robust. Many of the serrations are evident on the tooth. The tip displays a small amount of wear. The tooth has been repaired (normal), but there is no reconstruction. This is a good example of a large tooth of a meat-eating dinosaur.
