Not all of the fossil fish that are dug from the layers of siltstone in SW Wyoming pop out of the ground intact. In fact, there are lot of partial skeletons that show the features of these fish; they are just not complete. We have rescued these fish from the junk pile and send them to you at a greatly discounted price. These fish skeletons are 50 million years old, found in the Green River Formation, and are perfect for young paleontologists.
