Tyrannosaurus rex

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 has 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.
