.65" Theropod Phalange (Toe Bone) - Judith River Formation

This is a very nice, .65", Theropod phalange (toe bone) from the Judith River Formation, Montana. The bone is in very good condition with only minor weathering around the edges and no repair or restoration.

There are a number of theropods from the Judith River Formation and specific identification from an isolated toe bone is highly problematic.

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.
