This is an excellent Tyrannosaurus tooth recovered from our partner's private lease in Carter County

Debate:
1) Nanotyrannus vs. T-Rex (teeth that are longer, thinner, and more compressed with a pinched base are labeled Nanotyrannus.
2) Larger teeth with a more rounded tip and no pinching at the base are labeled T-Rex, scientifically proven!!!!

No restoration - no repair.
Very nice Nanotyrannus fossil tooth for collectors.
The teeth on the distal and mesial edges are excellent.
Certificate of authenticity included.
