Tertiary dinoflagellate, acritarch, and chlorophyte assemblages from the Oak Grove Core, Virginia Coastal Plain
… the Paleocene (Thanetian) age indicated by the calcareous nannofossils, Foraminifera, ostracodes, and pollen and spores for the Aquia strata; certain dinoflagellate and pollen species in the lowermost 11.5 m (37.9 ft), however, suggest this basal interval, devoid of other microfossils, could be …

PCO2 EFFECTS ON THE PRODUCTION OF PELAGIC BIOGENIC CARBONATE AND OCEAN CHEMISTRY: A CASE HISTORY FROM THE CRETACEOUS.
… through an integrated micropaleontological (calcareous nannofossils) and geochemical (Re-Os isotopes, C and O stable isotopes) approach. Calcareous nannoplankton, responsible for primary productivity and effective producers of calcite, affect the C-cycle on both long- and short-term time …
