.91 Inch Partial Tyrannosaurid Tooth, T-Rex

Here is a partial Tyrannosaurid tooth from the Hell Creek Formation of Montana. This would have either been a Tyrannosaurus rex or Nanotyrannus lancensis, though many paleontologists believe they were the same dinosaur and not two seperate species. The tip is broken off but it has very nice enamel preservation and the serrations are in good shape.
