The Dentary of a Tyrannosaurus Rex
Tyrannosaurus Rex
Late Cretaceous Period, Maastrichtian Stage (approx. 67 million years ago)
Hell Creek Formation, Dawson County, Montana, USA
Complete dentary of a fully-grown Tyrannosaurus rex with 5 erupted teeth. Dentary measures 20.5 inches long by 9 inches high from the tip of the tallest tooth to the bottom of the jaw. 15 inches high on custom metal armature.
Judging from the overall size and degree of the bone development, it can be determined that this mandible belonged to a large, mature individual.The bones are preserved in exquisite detail, exhibiting little distortion, and retaining much of their original shape and surface characteristics. The fossilization is superb, with normal foramina and nutrient grooves visible.
The five teeth emerging from the bone are well-preserved and measure approximately 4.75 inches, 4.25 inches, 2.5 inches, 2.75 inches, and 1 inch respectively. All have complete crowns and intact enamel, serrations, and tips without repair or restoration. The enamel exhibits a walnut brown patina.
