    To be seen on the matrix below the ammonite are 2 Myophorella formosa bivalves on the right and a Staufenia opalinoides ammonite. The shell on one side is completely preserved. The other side shows the calcite mold with sutures on the phragmocone. Only a small section of the body chamber on this specimen is preserved. If complete, it would probably have had a diameter of approximately 16cm. This is the index fossil of the subzone.
