MGooden Posted December 14, 2022 Share Posted December 14, 2022 (edited) Good evening, brand newbie here. We recently went shark tooth hunting on the beach at Purse State Park in Maryland and along with sand Tiger/goblin/mackerel shark teeth, Gastropod internal molds, stingray dental plates, I collected a few other items that seemed unique. I looked online at some fossil sites for the Paleocene era but man I have to admit I was ready to toss these. Figured it was worth an ask here. I used the centimeter side of my ruler to take photos of each of the items and will post each in a separate post.

Not easy with the bryozoans, normally you need the internal structures, openings, chambers... But, for a first idea it will perhaps be possible Link to comment Share on other sites More sharing options...
MGooden Posted December 15, 2022 Author Share Posted December 15, 2022 Can you tell me what time period this would have been from? I'm googling but confused as to when this fossil would have come from. Link to comment Share on other sites More sharing options...

The Nanjemoy Fm is the fossiliferous strata at Purse (one of my favorite collecting locations in days of yore), and is late Paleocene/early Eocene. Your bivalve belongs to the oyster family, but I don’t know the genus or species. I recall finding them there.

Your bivalve belongs to the oyster family, but I don’t know the genus or species. I recall finding them there. Purse State Park has exposed zones 2 through 5 of the Paleocene Aquia Formation. Zones 3 and 5 are hard indurated layers. You have to go further downriver from Purse State Park to find exposed the early Eocene Nanjemoy Formation.
