Zonation of Upper Cretaceous by means of planktonie foraminifera, Attersee, (Upper Austria)

Abstract

From 90 samples from the „Helvetikum” and „Ultrahelvetikum” respectively, of Attersee (Upper Austria) a series of 11 zones is established on the basis of the planktonic Foraminifera found; these correspond approximately to the stratigraphic range Albian to Maestrichtian. Pictures are made of the fossilia supplying the names to the zones.
