Green River Formation Insect Fossils Association

The Green River Formation deposits of Wyoming, Colorado, and Utah are best known for their immaculately-preserved fish, but other examples are known as well, as this specimen attests. This is an example of association plaque of a number of insects. There is a fine ant, a pair of wings with delicate venation, and some others. This is a fine association plaque sure to become a prized addition to any Green River fossil collection.
