Platyceras and Nanticonema gastropods from the Centerfield Mbr. of New York

I have not found too many Gastropods in the Centerfield mbr. of the Ludlowville Formation, but when I do it's just two genera: Platyceras and Nanticonema (formerly Platystoma).

This is a small Platyceras sp. gastropod

And this is a typical Nanticonema sp. gastropod.

Both specimens were found near East Bethany, NY. The Ludlowville Formation is Devonian in age (Givetian stage).
