Rare Positive and Negative Fossil Stingray, 50 Million Years Old. Stingrays (Heliobatis radians) are among the rarest and most beautiful of all the fossils from Green River, Wyoming. Most of these stingrays occur as a single fossil, but rarely is one slab split open to reveal both a positive (with bones) and negative (counterpart) of the delicate fossil. This nearly complete 9 in. stingray is a perfect example of such splitting. Only about 1 inch at the front of the rays has been restored. Stingrays are cartilagenous like sharks and do not have a solid bone skeleton. The positive half of the ray has the very tiny bones of the "wing" and the complete tail with some of the tiny black tail vertebrae scattered around the tail. The negative half contains the complete body outline and some tail vertebrae, as well as the complete stingers. This is a rare opportunity to purchase two fossil slabs that both illustrate the fossil process and contain a rare and interesting fossil ray. Allow $35 for shipping.
Estimated Value $1,000 - 2,000.
