A nice quality Tyrannosaurid tooth from the Judith river formation. The exact species is unknown but is most probably either Albertosaurus, Gorgosaurus or Daspletpsaurus as these are the three main tyrannosaurids found in this area. The tooth itself has been repaired with glue and has some chips and damages but no restoration in the form of reconstruction. Has lovely serration. 
This is the exact tooth you will receive, all fossils are genuine so will have damages/repairs.
