Staufenia ?sehndensis (Hoffmann 1913)

14.5cm. Not quite sure about the ID. It's missing a bit, but I've kept it due to the rarity of the species at this site. From the Staufensis Bank, Bradfordensis Zone, upper Aalenian in the Wutach Valley.

A few days later: I've edited the ID, filled in the gaps with stonemeal and placed a new picture.
