Teeth under 3" of these three genera are very hard to differentiate and there is no scientific method for doing so. Thus, this tooth must be labeled as Tyrannosaurid indet.

This is a very nice specimen, but was found in two parts and had to be glued back together. There is also a bit of repair as well as the photos show. The serrations are slightly worn, but are still visible; an attribute which is not common. It comes with the acrylic case.
