Athyris concentrica brachiopod from Eifel, Germany

I have yet another species of Athyris from Germany which makes three compared to the single species that I find here in New York and Pennsylvania.  Athyris concentrica comes from the Devonian, Eifelian stage, aged Junkerberg formation, near Gondelsheim, Eifel, Germany. The shell is generally round with a shallow sulcus and narrow concentric growth lines decorating the surface. This species looks very similar to A. vittata from Michigan.

Compare this species to others from Germany, A. tumida and A. amanshauseri or here in N. America, A. spiriferoides from New York.
