.50" Juvenile Tyrannosaur Premax Tooth (Aublysodon) - Wyoming

This is a very interesting Tyrannosaur tooth from the Lance Creek Formation of Wyoming

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 .50" long and likely would have come from either Tyrannosaurus rex or Nanotyrannus lancensis. Really nice enamel preservation. Comes with an acrylic bubble case.
