Indefinite orthocone cephalopod remains as well as seven late F'amennian ammonoid species are described
   from the Refrath 1 Borehole (Bergisch Gladbach-Paffrath Syncline).  The composition of the fauna suggests
   an age between the Platyclymenia annulata Zone and the Clymenia laevigata Zone (middle to late Famen-
   nian).  The first Famennian anaptychi are reported from the Ardennes-Rhenish Massif.
