The importance of thegloboconusa daubjergensis-kozlowskii gens as a time-marker in the lower tertiary

  • J. Hofker


Globoconusa kozlowskii (Brotzen & Pozaryska) was found in the DSDP drill hole 47.2 in theTruncorotalia uncinata zone as the direct continuation ofG. daubjergensis (Brönnimann). As this species was found by Brotzen & Pozaryska in the typical Montian foraminiferal fauna, it is obvious that the Montian ist younger than the Type-Danian, the zone of which is characterized byG. daubjergensis. This species has been found typically in the underlying S.trinidadensis-pseudobulloides zone in the drill hole 47.2. With this discovery, the time of the layers with the Montian fauna (Tuffeau de Ciply, Calcaire de Mons, highest part of the Me* and the Bunde Fauna in South Limburg) is definitely established. *P = Paleocene; Me = Post Maestrichtian (above Type-Maestrichtian) = Danian; Md = Upper part of Maestrichtian Tuff Chalk.

Globoconusa kozlowskii (Brotzen & Pozaryska) wurde in der DSDP Bohrung 47.2 in derTruncorotalia uncinata-Zone als direkte Fortsetzung derG. daubjergensis (Brönnimann) aufgefunden. Da diese Art von Brotzen & Pozaryska in Polen zusammen mit der typischen Montien-Foraminiferenfauna gefunden wurde, ist das Montien offenbar jünger als die Typ-Dan-Fauna, die auch in der Bohrung 47.2 durch das Auftreten in der Zone mitS. trinidadensis-pseudobulloides gekennzeichnet ist. Mit dieser Entdeckung ist die Zeit der Schichten mit der Montien-Fauna (Tuffeau de Ciply, Calcaire de Mons, höchstes Me* und die Bunde-Fauna in Süd-Limburg) sichergestellt.
