3.7" Ceratopsian Dinosaur Ungual - Judith River Formation

This is a 3.7" long fossil Ceratopsian dinosaur ungual (distal phalange bone) found in the Judith River Formation of Montana. The cortical bone has almost completely weathered away from this specimen. There is a repaired crack through this bone, with some addition fractures throughout the bone which didn't require repair.

Comes with an acrylic display stand.

Within the Judith River Group there are multiple Ceratopsid genera and species, so with just a single bone or tooth they are hard to differentiate and give a definitive identification.

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.
