I bought this tyrannosaur tooth a while back and it says it’s a albertosaurus, gorgosaurus, or daspletosaurus. Is there anyway to narrow it down any further? It says it was found in the Judith river formation of eastern Montana and it measures just over an inch. Any and all help is appreciated.188E6BAF-78AE-49AE-A397-C93B19A38570.thumb.jpeg.6beb68cbec56626da3f1742366ac4868.jpegFBE55261-E7C3-4085-82BB-38B86928749B.thumb.jpeg.a46d536bb00c53b246d5cc30bd32679e.jpegF62640BB-7275-4BFB-BC26-0A8B0046DC5E.thumb.jpeg.562835cf15cbc0a384ffafc31d06bc1c.jpeg

Its all about provenance and easten Montana is not a good one.  Its not Albertosaurus those are found in Alberta.  Eastern montana could be HC and preservation is more that than JRF.

Okay its JRF then its an Indeterminate Tyrannosaurid.   Daspletosaurus and Gorgosaurus have yet to be described from the JRF and it would be difficult to assign it to either if they were.
