Perfect 12" Heliobatis Stingray Negative - Wyoming

This is a perfect negative of a rare and highly desirable, Heliobatis radians stingray from the Green River Formation in Wyoming. It's Eocene in age and was collected from the split fish layer at Warfield's Quarry near Kemmerer Wyoming. The ray is average size at 12 inches in length (straightline) on a very solid 14 by 10.5 inch slab of natural matrix. It has not been restored or color enhanced.

These rays are one of the more rare fossils from the Green River Formation and are highly coveted by collectors for their beauty. I can only imagine the look on the collectors face when he split on this perfect example. The positive likely would have fetched in the area of $4,000 given how perfectly preserved this 50 million year old fossil is.

Heliobatis is an extinct genus of freshwater ray primarily known from the Green River Formation in wyoming. The teeth are triangular and shaped for feeding on small fish, crustaceans, and mollusks.
