Exceptional 14" Heliobatis Stingray Fossil - Wyoming

This is an exceptional specimen of a rare Heliobatis radians stingray from the Green River Formation in Wyoming. It's Eocene in age and was collected from the "18 inch layer" at Warfield's Quarry near Kemmerer Wyoming. The 18 inch layer produces much darker colored and more detailed fossils than the split fish layers.

The ray is 14" in length (straightline) on a 15x11.5" slab of natural matrix. These rays are one of the more rare fossils from the Green River Formation and are highly coveted by collectors for their beauty.

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.
