A new specimen of Productella spinulicosta from Arkona

Another cool fossil find from last fall at Arkona is this Productella spinulicosta brachiopod with some of the spines still intact. I found it on a weathered slope that exposes both the Widder and Arkona formations (both are Devonian, Givetian stage) so I can't say for sure which set of rocks it came from. Previously I've only found specimens of this species with no intact spines.
