Tyrannosaurus fossil tooth (Nanotyrannus lancensis). - Fossil tooth - Hell Creek formation - Carter County - Montana - USA !!!

A superb fossil tooth (Nanotyrannus lancensis)!!!!
Tyrannosauridae family
Formation: Hell Creek Formation
Location: Carter County - USA.
Geological period: Late Cretaceous
Geological stage: Maastrichtian (67 to 66 million years ago)
Tooth measurement: 1-1/4 in straightline - (3.18 cm)
This is an excellent Tyrannosaurus tooth recovered in the private lease of our partner in Carter County

Debate:
1) Nanotyrannus vs T-Rex (longer, thinner, and more compressed teeth with a pinching at their base are labeled Nanotyrannus.
2) Larger teeth with a rounder tip and without pinching at their base are labeled T-Rex, scientifically proven!!!!

No restoration - no repair.
Very nice Nano fossil tooth for collectors.
The dentition on the distal and mesial edges is excellent.
Certificate of authenticity included.
3D floating frame included.
