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.

It 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 world's 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 reptiles and 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 found with amazing soft-tissue preservation: skin impressions can be found on 90 percent of its body! The pattern in the skin on its 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.
