Bivalve shells
Greetings @seanna-carter ! Your specimen appears to be an external mold of a brachiopod like Vinlandostrophia.
@nathan-newell may be able to provide a more precise ID.
At minimum it is a platystrophid brachiopod. A flying guess is Vinlandostrophia ponderosa.
I might he wrong though now that I check the geochronology of Lorton.
…which is largely early Cretaceous.
So scallop like bivalve seems appropriate.
@matthew-granting thank you so much for your inputs. My son was so excited to get more information.
@seanna-carter Glad to be of service! Happy collecting to the whole family!
Cool specimen, @seanna-carter ! I think you’re right, @matthew-gramling , it seems like that area is from the Cretaceous and there aren’t any brachiopods in that formation, at least according to Rockd. I’m not able to place it any more specifically than just as a bivalve, though. The species Rockd listed didn’t look similar to this.
Thanks for the confirmation @nathan-newell ! I tried looking up fauna of the Potomac Formation, but could not find much on bivalve species.
But, it looks surprisingly like a brachiopod.
@matthew-gramling I agree, it really does look like a brachiopod. It kinda threw me when I was trying to ID it. If this was from another formation, I would totally assume it was a brachiopod.
@nathan-newell The mysteries of convergent evolution lol.
