My young friend Mason (8yo) brought me this fossil, found in a dry creek bed in north eastern Sumner Co. Tn. I'm really excited to learn that this is a Mississippian outcrop and only a 45 min. drive from here, now to find someone who will let me hunt their property.. anyway this is a fairly large brachiopod, bigger than any I've found around here. I've been doing a lot of searching and the closest I can get to an id would be Platystrophia but I'm just not sure. He's very curious and I told him I would try to get an id. for him, so do you think I'm anywhere close to the ballpark?
