Graptolites from the Ordovician of Rügen (northern Germany, Western Pomerania)

Graptolite faunas from the Holmograptus lentus, Pterograptus elegans, Hustedograptus teretiusculus and Nemagraptus gracilis Zones are identified in the Ordovician succession of Rügen. The well sections bear incomplete, often fault-bounded successions. Tectonic stacking is present in the Rügen 3h core. A sedimentological gap is expected in the Arenig. About twenty graptolite species are described and their local biostratigraphic ranges are documented. Most of the faunal elements are described for the first time from the Ordovician of northern Germany. The faunal associations belong to the Atlantic Faunal Province.
