2" Cretaceous Coprolite (Poop) With Seed? - Judith River Formation

Cretaceous Coprolite (Poop) With Seed? - Judith River Formation #144923

This is a highly unusual fossil from the Late Cretaceous, Judith River Formation of Montana. It appears to be a coprolite (fossil poop) with some type of seed preserved inside if it and visible on the broken end. The entire coprolite is 2" long, and we can only guess at what might have produced it. The Judith River Formation represents an environment near the shoreline so you can get a mix of terrestrial fossils like dinosaurs along with fish, reptile and amphibian fossils.

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.
