This is an exquisite, museum quality female Stingray specimen called Heliobatis radians (Order: Rajiformes; Family: Dasyatidae), and one of only two species of ray from the Green River Formation. This stingray has been back and comes with a French Cleat, ready to hang. Like modern stingrays, this extinct genus had spikes on its tail. The preservation is fantastic and the preparation is as good as it gets. This one is known to be a female due to the absence of claspers used by the male in mating.
Rays belong to the Chondrichtyes, as do the sharks. All have an inner skeleton made of cartilage. Since cartilage comprises more organic material (collagen and elastic tissues) than bone, it decays more rapidly. As a result, fossils of cartilaginous fishes generally are rare. The cartilaginous fishes appeared in Silurian time, and their ancestors remain one of the most successful groups of marine animals. This ray has a restored tail and small repairs to its raylike skeleton. It is an amazing display piece.
