Spinocyrtia granulosus brachiopod from Arkona

This is a partial pedicle valve of Spinocyrtia granulosus that I found at Hungry Hollow near Arkona, ON recently. It's very large and is the only specimen that I have of this species from the Hungry Hollow member of the Widder formation (Devonian, Givetian stage).

Note the bryozoan holdfast
