Serrated, 1.47" Tyrannosaur Tooth - Judith River Formation
This is a 1.47" long Tyrannosaur tooth from the Judith River Formation of Montana. This formation is approximately 75 million years old, or about 9 million years older than the Hell Creek Formation which also produces T. rex. This specimen has very good enamel and serration preservation along both edges. There is a repaired crack at the tip and missing denticles from both the mesial and distal edges. There are also a few repairs with small gap fills right at the base of the tooth.
The Judith River Formation is one of the most prolific sources of Late Cretaceous vertebrate fossils. At least sixteen Orders containing more than forty Genera are known from the formation. These include fish, amphibians, mammals, and insects in addition to the reptiles, avian and non-avian dinosaurs (birds). Among the more interesting specimens is Leonardo, a mummified and fossilized Brachylophosaurus. This is a Hadrosaur, a duck-billed dinosaur with amazing preservation of the soft tissues of the body. The pattern in the skin of the feet is even preserved. In addition to Leonardo, the Judith River Formation contained the remains of the theropod Hesperornis, the only known freshwater Hespernorthid, a penguin like bird.
Comes with a floating frame display case.
