Composita subtilita is the most common brachiopod in the Pennsylvanian Naco Formation in central Arizona. This silicified one was found while etching out a giant horn coral. The red Beekite chalcedony dots give this one character. Photo 1 Brachial valve. Photo 2 Pedical valve. Photo 3 Closure with sulcus. Photo 4 Shell with giant silicified horn coral.
