Potomac River Finds

[pinkus]

Hi.  We visited Purse State Park for the first time a few weeks ago and my son loved collecting the little snails that were littering the bank. He's putting little baggies of shark teeth, ray teeth, and the snails together for his classmates and I'm hoping I could get some more information on the snails. They are approximately 2 cm in length. Are these modern? I can't imagine they are from the Aquia Fm.  Thanks

Yes they are recent fresh water snails but I don't know the genus/species.  The Aquia mollusks are quite distinctive:  Turritella mortoni, Ostrea sinuosa, Cucullea.

I agree with Mike.

Try to compare with the Pleuroceridae - Pleurocera, Elimia, Juga genera.
Pleurocera virginica (Say, 1817) is widespread in eastern rivers and creeks, and is frequently observed in shallow water along the shore of the Potomac River.
