SOLD!!

This necklace features a Tyrannosaurus Rex Tooth tip measuring approximately 1.1" in length, 0.6" wide, and 0.5" thick. The tooth comes from the Hell Creek Formation in South Dakota and has beautiful serrations.

Above: Samples of dinosaur bone beads. The beads vary widely in color and texture. Each is unique and beautiful.

As pictured below, the tooth has been capped with a generous amount of sterling silver.

Given the size of this piece, we've paired the pendant with a thick 18" (45cm) sterling silver necklace. If you would prefer a different length (20 or 24"), let us know and we can make the change at no additional charge. We can also swap the heavier chain for our thinner, box-style necklace.

As pictured above, the necklace arrives in a black display box. A large certificate of authenticity will be included as well as a copy of our Age of Dinosaurs Companion Guide.

More About Tyrannosaurus rex

Above: How do you like your T. rex? With scales or fluffy like a baby chick? The science is still unsettled about adults as depicted here but juveniles definitely had feathers.

"We need to start thinking of dinosaurs as not just brutes and not just monsters, and not just things with sharp teeth and sharp claws, but as really active, intelligent, energetic animals that oftentimes had keen senses. An animal like T. rex was a predator that used brain and brawn: its big brain, its great sense of smell and its really keen sense of hearing were probably as important to it, if not more so, than its sharp claws and its sharp teeth and its big jaw muscles."

~ Steve Brusatte, Paleontologist, University of Edinburgh, author of "The Rise and Fall of the Dinosaurs: A New History of a Lost World" (2018)

Various mechanical studies of T. rex power place the "Tyrant Lizard King" firmly at the top of the charts. Paired with this incredible power, T. rex also had some of the largest teeth of any carnivorous dinosaur, with the largest measuring 1ft (30 cm).

Despite popular depictions of poor depth perception, studies show that when compared to other giant theropods, tyrannosaurids had a wide postorbital skull which resulted in forward-facing eyes and acute binocular vision. The spine of a Tyrannosaurus Rex was subject to tremendous force. The size and strength of the vertebrae were essential to providing support for this enormous predator, but the entire apparatus also had to allow for rapid changes in movement and critical striking speed.

Studies suggest the great tyrannosaurids achieved their huge size through accelerated growth spurts. At the peak of its growth spurt, a young T. rex may have put on the better part of a ton annually.

Bite marks from conspecifics have been found on the skulls of large tyrannosaurids, suggesting they may have bitten each other in dominance or reproductive interactions. It’s possible some species were gregarious, perhaps even pack-hunters; the first known tyrannosaurid trackway, from a Late Cretaceous formation in British Columbia, hints at three animals traveling together.

Among the other dinosaurs bearing tyrannosaurid bite marks are ceratopsids, hadrosaurs, and other tyrannosaurs (reflecting the sort of opportunistic cannibalism also widespread among predators). Sauropods such as Alamosaurus, which overlapped with T. rex in North America, and Opisthocoelicaudia, which shared Asian landscapes with Tarbosaurus, may also have been tyrannosaurid quarry.
