.85 Inch Nanotyrannus Tooth From Montana

This is a small Tyrannosaurid tooth from either a Nanotyrannus lancensis or a juvenile T-Rex. Though there is much debate about whether they are really the same species. It's .85 inches in length with good enamel preservation. Both the posterior carina serrations and the anterior carina serrations are present but worn with just a bit of feeding damage to the tip.

This tooth comes from a private dig in the Hell Creek Formation of Montana. The Hell Creek Formation represents a sub-tropical floodplain which would have been similar to coastal, modern-day Louisiana.
