    • This is a female Stingray specimen called Heliobatis radians and is one of only two species of ray from the Green River Formation. Like modern stingrays, this extinct genus had barbs on its tail. This one is known to be a female due to the absence of claspers used by the male in mating.

    Oh man, that stingray looks funny. Better send it to me for my collection. I wouldn't want the forum to have to take away your GDB!
