Hello! I have this juvenile stingray here from the green river formation, F2. The seller labeled it as a Heliobatis radians. At first I was taking his word on the ID but is it possible this is an Asterotrygon? I know the chances are very slim but I have reasons to believe this is an Asterotrygon: 1. Asterotrygon is more common from the F2 beds, this is from F2. 2. The general body shape leans more towards Asterotrygon than Heliobatis. 3. The tail looks shorter than other Heliobatis juvenile tails I've seen. Also the base of the tail shows some developed denticles, possibly the early growth stage of the thick tail of an Asterotrygon. Overall I know this is all probably wishful thinking, but I'd love to hear the opinions of you all.
