.91" Partial Tyrannosaur Tooth - Montana

This is a .91" long partial Tyrannosaur tooth from the Hell Creek Formation of Montana. It has a some beautiful enamel and some sharp serrations to the posterior edge. It comes in an acrylic display case.

The tooth is likely from Tyrannosaurus rex, likely a juvenile. It is less likely that it is from a large 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.
