The enamel is the very good quality with some wear. Great brown & black color. A massive extra wide tooth. You can see why this bone crusher is referred to as a "banana tooth". Overall the tooth is very good quality with typical crack fill and some wear from tumbling down a Hell Creek stream. This is a real ~6" tooth.

T-Rex was the apex during the late Cretaceous with massive teeth capable of crushing its prey. See the detailed description to determine how to tell a real T-Rex tooth! Legally collected on privately deeded land in the Hell Creek Fm., Powder River Co., Montana. Authenticity guaranteed.  Note - a Riker frame is included. This is a BIG high quality collector's tooth.
