    Identification

    Tyrannosaur teeth have similarly-sized serrations on each edge, and the serrations are chisel-shaped. This is a classic "Nano-morph" tooth being compressed and blade-like (which is the primitive condition of Tyrannosaurs). 

    Notes

    This tooth has excellent preservation, with serrations crossing the tip, and clear enamel. There is a minor wear facet near the tip on the lingual side, indicating this is from the left maxilla.
