Bargain .63" Tyrannosaur Tooth - Montana

This is a .63" long Tyrannosaur tooth from the Hell Creek Formation of Montana. Its enamel has been weathered away, but you can still see faint indications of the serrations. It comes in an acrylic display case.

The tooth is likely from either small Tyrannosaurus rex or Nanotyrannus. There is a hot debate among paleontologists about whether Nanotyrannus and Tyrannosaurus rex (T-Rex) are really the same species, with Nanotyrannus representing juveniles. Recent finds that are soon to be published should put this debate to rest, definitively proving that Nanotyrannus is in fact a separate genus and valid genus. Nano teeth tend to be much more finely serrated, and much thinner/blade like t-rex teeth, in addition to being smaller.
