.85" Fossil Dromaeosaurid Phalanx on Sandstone - Judith River Fm.

Fossil Dromaeosaurid Phalanx on Sandstone - Judith River Fm #313456

This is a really cool, .85" long dromaeosaurid dinosaur phalanx that has been nearly completely exposed from the rock it was found in. The specimen comes from the Judith River Formation in Hill County, Montana.

There are multiple species of Dromaeosauridae that come out of the Judith River Formation, making it difficult to provide an accurate species for this specimen. There is a repaired crack through the middle of the bone.

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 (birds) and non-avian dinosaurs. 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.
