Spinatrypa curvirostra brachiopod from Germany

Spinatrypa curvirostra is a species of brachiopod from the Rodert member of the Cürten Formation (Devonian, Givetian stage) near Sötenich, Germany. I can directly compare it to specimens of S. spinoa from the Windom shale of New York (with and without spines preserved) as well as S. aspera from Poland and S. rockfordensis from Iowa. It is generally smaller and less robust than most specimens I have found in the Windom shale but retains the same general look with it's growth lines that resemble pie crust.
