Douvillina interstrialis brachiopod from Poland

Douvillina is a genera of Brachiopod that I only recently recognized in fossils that I was finding. It started with specimens from the Ludlowville and Widder formations and then I received some specimens from Iowa. Now I have specimens of Douvillina interstrialis from the Skaly beds of Poland for comparison.
