Huge, 2.6" Pyrite Replaced Brachiopod (Paraspirifer) - Ohio

This is a large brachiopod fossil of the species Paraspirifer bownockeri that has been replaced by glittering pyrite. It comes from the Devonian aged Silica Shale near Sylvania, Ohio. The quarries where these brachiopods used to be found are now closed to collectors so they are much harder to acquire.
