.72" Tyrannosaur Premax Tooth - Montana

This is a .72" Tyrannosaur premaxillary tooth from the Hell Creek Formation in Carter County, Montana. The serrations have completely worn from one edge, though some still remain on the opposite edge. The enamel is in great condition and there is feeding wear to the tip.

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 the Judith River Formation have led to the discovery that these teeth are actually the premaxillary teeth from juveniles of other Tyrannosaur species.
