.4" Rooted Crocodilian Tooth - Judith River Formation

This is a partially rooted, .4" long tooth from the Judith River Formation of Montana. This formation is approximately 70 million years old, or about 5 million years older than the Hell Creek Formation which produces T-Rex. It appears to be crocodilian.

Comes with an acrylic display case.

There are a number of genres of crocodiles and alligatoroids described from this formation with very similar teeth. Typically most of these teeth just get assigned to Leidyosuchus by collectors however in 1997 several species of Leidyosuchus were reassigned to Borealosuchus.

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 contains the remains of the theropod Hesperornis, the only known freshwater Hespernorthid, a penguin like bird.
