Calcareous nannoplankton evolution: a tale of two oceans

Micropaleontology, 2005
Calcareous nannoplankton diversity, evolutionary rates and species longevity show markedly different characters above and below the Cretaceous/Tertiary boundary. Excluding mass extinction events, and the initial origination and radiation, Mesozoic nannoplankton diversity is characterized by relatively continuous increase with low background ...

Transgressions, climatic change and the diversity of calcareous nannoplankton

Marine Geology, 1973
Abstract Plankton-diversity models of various authors are examined in the light of available diversity data on calcareous nannoplankton. To account for the diversity peaks during times of widespread epicontinental seas in the Mesozoic and Tertiary, a new explanation is given.

Paleogene calcareous nannoplankton biostratigraphy of northwestern Europe

Palaeogeography, Palaeoclimatology, Palaeoecology, 1986
Abstract The classic Paleogene stages (Thanetian, Cuisian, Lutetian, Bartonian, Ludian and Stampian) defined in the epicontinental deposits of the Anglo-Paris Basin(s) are placed within a standard biostratigraphic framework based on an analysis of their calcareous nannoplankton floras. Relatively precise biostratigraphic correlations can be made with

The pleistocene calcareous nannoplankton of the subantarctic Pacific Ocean

Deep Sea Research and Oceanographic Abstracts, 1972
Abstract The stratigraphic distribution and relative frequencies of Pleistocene calcareous nannoplankton from eight subantarctic cores and one subotropical core have been determined. The extinction and first appearance of certain species allow the division of the Pleistocene into four zones.
