.73" Juvenile Tyrannosaur Premax Tooth - Montana

This is a Tyrannosaur premax tooth from the Hell Creek Formation of Montana. These oddly shaped teeth with two ridges located on the lingual side where originally described as Aublysodon more than a century ago based off of isolated teeth and jaw fragments. More recent discoveries of more complete Tyrannosaur skeletons from this formation has lead to the discovery that these teeth are actually the premaxillary teeth from juveniles of other Tyrannosaur species.

The tooth is .73" long and likely would have come from either Tyrannosaurus rex or Nanotyrannus lancensis. There is a repaired crack at the tip of the tooth. Comes with an acrylic display case.
