$7,800.00

In stock

North America, Western United States, Late Cretaceous, ca. 68 to 65.5 million years ago. A fossilized tooth from the iconic Tyrannosaurus rex, the formidable “Tyrant Lizard King,” one of the most recognizable predators of the prehistoric world! The tooth retains its thick conical form and serrated edge, and the tip exhibits distinct wear facets – flat, polished surfaces created during the animal’s life through repeated bone-crushing and shearing as it fed on prey. These feeding traces provide direct evidence of the powerful bite forces and bone-processing behavior characteristic of T. rex! At 2.3″ long, this tooth is an impressive example, as larger Tyrannosaurus rex teeth are increasingly scarce on the market and highly sought after by collectors for their size, strong form, and clear evidence of feeding wear. Size: 2.3″ L x 0.9″ W (5.8 cm x 2.3 cm); 6″ H (15.2 cm) on included custom stand.

The most famous dinosaurs of all time are undoubtedly the large, meat-eating members of the Tyrannosauridae family. This family includes species such as Nanotyrannus, Albertosaurus, Gorgosaurus, Daspletosaurus, Tarbosaurus, and the most infamous of all, Tyrannosaurus rex. The emergence of all tyrannosaurids was short-lived and occurred in only a 15-million-year span in the Late Cretaceous Period before their extinction about 65 million years ago. The first recognized fossil remains of Tyrannosaurus were discovered in Colorado, U.S.A. in the 1890s; one of the first partial skeletons came from the Hell Creek Formation in 1902.

Condition: Large fragmentary piece with loss to root area as shown. Intact serrations. Wear facets to the enamel tip. Losses to enamel and small abrasions and striations, but otherwise stable and nice preservation. Comes with removable display stand.
