Green River Female Heliobatis radians Stingray Fossil Fish
This 50 million year old fossil fish, often called a stingray, is a ray in the Class Chondrichtyes, as are all sharks. The Chondrichtyes fishes have no bones, and their inner skeletons are made of cartilage. Cartilage decays more quickly, making preservation as a fossil less probable. This fish fossil comes from the Green River Formation of Wyoming that yields an enormous number of fossils. Among, some are quite rare, as is this ray. Arguably, Heliobatis is the prettiest of these fossils, and I’ve never seen a photograph that does them justice. This is a particularly nice specimen.
