This is a rare Troodon tooth from the Judith River Formation of Montana. Troodon teeth have very distinctive, prominent, prominent, apically oriented serrations. These serrations are morphometrically more similar to those of herbivorous reptiles, and suggest a possibly omnivorous diet. Troodon teeth are quite rare and some of the most sought after dinosaur teeth.
Comes in an acrylic display case.
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.
