?Oepikina minnesotensis. I'm not 100% sure yet. Oepikina tend to have very fine costae and those specimens are literally loaded with costae making them darker. There's two in the leftmost rock specimens along with a Strophomena. The annoying thing is its hard to see hinge line for a positive id. Among the most inflated brachiopod I have seen from Decorah formation, only inarticulate brachiopods are this inflated.
From the album:
Brachiopods of Platteville/Decorah Twin Cities Minnesota
