Standard Palaeogene Calcareous Nannoplankton Zonation
THE stratigraphic value of a group of marine minute algae usually referred to as the calcareous nannoplankton, first shown by Bramlette and Riedel1, has already been discussed2. A standard zonation, based partly on the investigations of Hay et al.3 and Bramlette and Wilcoxon4, has been proposed, and the Neogene calcareous nannoplankton zones have been numbered NN 1 to NN 21.
