1.03" Tyrannosaur Tooth - Hell Creek Formation

This is a 1.03" long Tyrannosaur tooth from the Hell Creek Formation of Montana. The tooth has nice, dark colored enamel and was collected from a private ranch in Powder River County, Montana. Most of the serrations are worn but there is no repair or restoration. It either came from a juvenile T-Rex or Nanotyrannus lancensis. Comes in an acrylic display case.

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.
