.74" Theropod (Juvenile Tyrannosaur or Raptor) Tooth

This is a small, .74" long theropod tooth from the Judith River Group or Eastern Montana. Because of the wear to the serrations ID'ing it as a juvenile/baby Tyrannosaur tooth vs Dromaeosaur (Raptor) tooth is mostly a guess. Though every small tooth I've looked at from the site appeared to be Tyrannosaur.

Comes in an acrylic display case.

There are three described Tyrannosaurs from the Two Medicine Formation (Judith River Group), Albertosaurus, Gorgosaurus and Daspletosaurus. Research done on teeth from these three Tyrannosaurs has concluded that isolated teeth are statistically impossible to assign to a specific genre because they are so similar. I've linked to the research paper below.
