Tyrannosaurus rex (T-Rex) Teeth & Fossils
Shop Authentic Tyrannosaurus Rex Tooth Fossils
Buried Treasure Fossils offers Tyrannosaurus rex teeth for sale. Tyrannosaurus rex or "tyrant lizard" was the infamous apex predator of the late Cretaceous period. This monster reached lengths of more than 40', stood 13' tall at their hips, and reached weights approaching 7 tons. Their teeth reached lengths of 12" including the root. T. rex teeth have been referred as "banana teeth" by the renowned paleontologist Bob Bakker, curator of the HMNS. The T. rex teeth are round or or close to round to withstand the massive bone crushing bite force exerted (up to 10,000 lbs), the greatest bite force of any land animal. A must have item for dinosaur collectors. Fossil remains in teeth, bones, and claws. All of which are very rare and extremely difficult to locate. These top quality specimens were all legally collected from private lands in the northwestern US. Late Cretaceous, Hell Creek Fm. (or equivalent), 68-66 MYA. Authenticity guaranteed.

Frequently Asked Questions
What makes each Tyrannosaurus rex tooth unique? Each Tyrannosaurus rex tooth reflects its own history of burial and fossilization. Differences in preservation and surface features give every specimen a distinct appearance. And there are differences in shape and size due to jaw position.
How can I display a Tyrannosaurus rex tooth safely? A sturdy display stand or protective case helps keep the fossil secure while making it easy to enjoy. Placing it away from direct sunlight helps preserve its condition over time.
Why do Tyrannosaurus rex teeth come in different colors? Natural minerals in the surrounding sediment can influence a fossil's appearance during the fossilization process. Depending on those conditions, authentic teeth may develop shades of brown, black, gray, tan, or other earthy colors.
Is a Tyrannosaurus rex tooth suitable for new collectors? Yes. Many people begin their fossil collections with a dinosaur tooth because it offers a direct connection to prehistoric life while fitting easily into a personal display or educational collection. Who wouldn't want to own a tooth from this iconic apex predator?
What should I look for when comparing fossil teeth? Collectors often compare overall preservation, visible serrations, enamel quality, and natural coloration. Also, tooth shape and size will vary with jaw position. Looking at these features can help you appreciate the individuality of each specimen and choose one that best fits your collection.
