[The ammonoid fauna from the Platyclymenia annulata Zone of Kattensiepen (Late Devonian, Rhenish
  Mountains.] - From the locality Kattensiepen near Warstein-Suttrop, an ammonoid fauna of the
  Platyclymenia annulata Zone is deseribed which consits of 1 1 species: Gundolficeras rotersi sp. n.,
  Gundolficeras prescheri sp. n., Prionoceras divisum (MÜNSTER 1832), Felisporadoceras felix (KORN
  1992), Xenosporadoceras ademmeri sp. n., Erfoudites suttropensis sp. n., Prolobites aktubensis
  BOGOSLOVSKY 1969, Roinghites bottikei sp. n., Platyclymenia annulata (MÜNSTER 1832), Platyclymenia
  subnautilina (SANDBERGER 1855), and Pleuroclymenia costata (LANGE 1929).  The genera
  Felisporadoceras, Xenosporadoceras, and Roinghites as well as the subfamilies Balviinae,
  Xenosporadoceratinae, Pleuroclymeniinae, and Nodosoclymeniinae are newly erected.  The fauna from
  Kattensiepen is isolated because of its largely endemic taxa.
