An ULTRA RARE High Quality, 6"+ Tyrannosaurus rex  tooth from a large adult T. rex. A May Fossil of the Month. This Rex crown measures 5-13/16" (straight line) or 6-1/4" (on curve) and 1-7/8" wide. 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".

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.
