Quadrithyris macrorhynchia brachiopod from Germany

This next brachiopod fossil is a little rough but you can get the general idea of what it looked like. It's Quadrithyris macrorhynchia from the Nims member of the Junkerberg Formation (Devonian, Eifelian stage) near Rommersheim, Germany. It looks a little like an Athyris vittata but compressed between the anterior and posterior ends. There are some very fine growth lines on the surface of the shell that are more obvious in the view of the brachial valve.
