An Ultra Rare EXTRA LARGE, Top Quality Tyrannosaurus rex tooth. Another August 2018 Fossil of the Month. This Rex crown measures 4-1/2" (straightline) and is thick (1-9/16") - a massive Rex tooth. The enamel is very high quality and a rich dark brown color. Good posterior and anterior serrations with a small amount of natural tip wear. An extra wide base. This is a big and heavy tooth. Note - this tooth was cracked in a freeze cycle as evidenced by the cracks in the top half of the tooth. The preparator did a exceptional job prepping this tooth and it is rock solid now. A small area of the cutting edge was rebuilt about midway on both the anterior and posterior sides (see final photo). Excellent overall condition for a big Rex tooth. A incredibly rare & special 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 private land in the Hell Creek Fm., Faith, Harding Co., So. Dakota. Authenticity guaranteed. Note - Riker frame included. The largest T-rex tooth (crown) that I have offered! Top quality Rex teeth over 4" are the holy grail of the dinosaur collecting world. You just can't find quality 4"+ teeth at any price.
Tyrannosaurus rex was the apex during the late Cretaceous. It weighed about 6 tons. It was about 40 feet long and 20 feet high. These specimens are from the famous Hell Creek Fm. (67 MMYA). All of these teeth were collected on private ranch land with the owners permission. Collection area includes Montana and So. Dakota.
How do you know if you are getting a real T-Rex tooth? Tyrannosaurus rex teeth have a few unique characteristics.
T-Rex teeth are massive and a cross-section that is much more cylindrical than other tyrannosaurs (which are more oval). They were powerful crushing teeth like no other tyrannosaur. I will always show an “end” photo.
T-Rex teeth enamel wall is thick when looking at the end. Again, this provides the massive crushing power for these teeth.
T-Rex teeth serrations are large and more “blocky” or rounded. The serrations are not fine and pointy sharp. T-Rex teeth did not neatly slice its prey. It would grab, crush, and tear apart its prey!
T-Rex tooth profile tends to be more straight line ( less curvature)
Know the formation that produced the teeth. If the tooth looks like a T-Rex tooth and it is from the Hell Creek or Lance Creek Fm., they are T-Rex teeth.
