Material

A total of 443 specimens from the Baddeckenstedt section, 38 specimens from the Söhlde section, 297 specimens from the Wunstorf Wu2010/1 core, 269 specimens from the Wunstorf Wu2010/3 core, and 19 specimens from the Wunstorf Wu2010/4 core.

Remarks

Initially described as Arenobulimina frankei by Cushman (1936), Frieg and Price (1982), and Frieg and Kemper (1989) described the clearly triserial chamber arrangement of this species. Therefore, we follow their classification as Vialovella frankei .

Occurrence

Very abundant to common in the uppermost Albian up to the upper Cenomanian. Last occurrence below the Facies Change at Söhlde and Baddeckenstedt and in the plenus Bed at Wunstorf.
