cngodles Posted May 13, 2021 Share Posted May 13, 2021 I found this a while back, but finally saw it as an Ammonoid. But which one I wonder. It is pretty thin. Unseen is the inner umbilical groove, but it’s likely not important for ID. Opposite side is unremarkable.

fifbrindacier Posted May 13, 2021 Share Posted May 13, 2021 Hi, i think that will be hard to identify it, but i agree that looks like an ammonoid.

cngodles Posted May 13, 2021 Author Share Posted May 13, 2021 These are the listed suture patterns for Pennsylvanian Ammonoids from the book Fossils of Ohio. I agree, I think it will be hard to confirm a genus, let alone family or order. No 1, or 3-6 are my best bets.
