摘要: The palynological assemblages from two Albian-Cenomanian boundary sections in North Bulgaria are described. samples analyzed yielded a diverse content including dinoflagellate cysts and miospores. Based on dinocyst nutrient productivity indices phase of enhanced availability high primary is inferred for the latest Albian interval. pronounced predominance peridinioid dinocysts this interval, namely O. verrucosum, scabrosum especially P. infusorioides considered to reflect eutrophic conditions. It coincides with increased phosphorus mass accumulation occurring at top part Upper Dekov Formation. OAE 1d indicated Tolovitsa karst spring section, based palynofacies dominated by amounts granular amorphous organic matter (AOM) related anoxic environmental These serve as evidence suggesting relationship between Cretaceous (including Palaeohystichphora infusorioides, Ovoidinium scabrosum) anoxic/suboxic conditions and/or productivity. pollen spectrum relatively stable vegetation patterns surrounding continental areas during after Albian/Cenomanian interval times formation. hinterland integrated mainly pteridophyte spores gymnosperms. area was Southern Laurasian floral province which characterized warm temperate subtropical humid climate. Angiosperms were still minor vegetation.
