B IOSTRATIGRAPHY OF SARAKHS (N.E. IRAN) AND NAFTE- SHAHR (N.W. IRAN) SECTIONS [PDF]
Journal of Sciences, Islamic Republic of Iran, 1992 It is the first time that biostratigraphic zonations of calcareous nannoplankton from Maestrichtian to Lower Tertiary deposits of Iran are reported. The required samples from the north-eastem and western parts of the country were selected from the stocks

Were Oceanic Plateaus Instrumental for Calcareous Nannoplankton Evolution?
, 2011 The history of calcareous nannoplankton shows a general increase in species richness through the Mesozoic. Fertility and chemistry of the oceans, climate and pCO2 seem instrumental for nannoplankton abundance, diversification and adaptation, but high ...

CALCAREOUS NANNOPLANKTON OF APTIAN OF MOUNTINE CRIMEA
Collection of Scientific Works of the Institute of Geological Sciences of the NAS of Ukraine, 2013 Вперше для Гірського Крима наведені дані про стратиграфічне поширення вапняного нанопланктону з аптських відкладів. Показана можливість виділення двох нанопланктонних зон: Chiastozygus litterarius (нижній апт) та Rhagodiscus angustus (средній-верхній апт). Межа апту та альбу встановлена за появою Prediscosphaera cretacea.
