1950. Flourensina intermedia Ten Dam , p. 15, pl. 1, fig. 16.

Material

A total of 35 specimens from the Baddeckenstedt section, 253 specimens from the Wunstorf Wu2010/1 core, 213 specimens from the Wunstorf Wu2010/3 core, and 1 specimen from the Wunstorf Wu2010/4 core.

Remarks

The systematic position, occurrence, and paleogeographical distribution of Flourensina intermedia is intensively discussed in Frieg and Kemper (1989). Like observed in the Konrad 101 core, and outcrops in the Münsterland Basin, Flourensina intermedia occurs frequently over the whole Cenomanian in Baddeckenstedt.

Occurrence

Abundant to common in the uppermost Albian up to the upper Cenomanian until below the Facies Change at Wunstorf and common to very rare in the Cenomanian at Baddeckenstedt.
