18" Fossil Stingray (Heliobatis) With Knightia - Wyoming
This is a stunning, 18" long fossil stingray (Heliobatis radians) from the Green River Formation in Wyoming. These rays are one of the more rare fossils from the Green River and are highly coveted by collectors for their beauty and rarity. The preservation on this ray is particularly exceptional!
The ray has been inlaid into this rock which already contained a nicely preserved Knightia fish fossil. The rock has been backed for stability and comes with a metal display stand. Upon request we can install wall mounting hardware to created an aesthetic hanging display.
There is one repaired crack at the base of the tail that runs through one of the pelvic fin bones. There are also two cracks half way down the tail, one which runs through the barbs.

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.
About Fossil Lake
50 million years ago, in the Eocene epoch, these fish thrived in Fossil Lake, which was fed by the Uinta and Rocky Mountain highlands. The anoxic conditions at the bottom of Fossil Lake slowed bacterial decomposition, prevented scavengers from disturbing corpses, and, most interestingly, suffocated creatures that ventured into the oxygen-starved aquatic layer. The result is a miraculous exhibition of Eocene biota: a subtropical aquatic community within sycamore forests, teeming with creatures such as freshwater stingrays, dog-sized horses, menacing alligators, early flying bats, and one of the first primates.
