Case studies of Mesozoic calcareous nannofossils

, 2004
Calcareous nannofossils (CN) are an important component of the marine phytoplankton since the Mesozoic. For the fossil record they serve as accurate stratigraphic markers and palaeoceanographic proxies. The overall objectives of this thesis are to improve our understanding of changes within the assemblages of CN and their morphological variability with
