Stable isotope and calcareous nannofossil assemblage record of the late Paleocene and early Eocene (Cicogna section)

diversity changes among calcareous nannofossil assemblages across the paleocene – eocene boundary in the zagros (southwest iran)

calcareous nannofossil assemblages of the boundary paleocene-eocene deposits (pabdeh formation) of the zagros, dezful embayment-mansouri oilfield have been studied in detail. it consists of shale and grey marlstone with inter layers of calcareous argillites and marly claystone. we present a study focused on changes in calcareous nannofossils of the pabdeh formation during the paleocene/eocene b...

Late Albian adaptive radiation in the calcareous nannofossil genus Eiffellithus

Well preserved nannofossil assemblages in upper Albian and lower Cenomanian hemipelagic sections from Ocean Drilling Program (ODP) Leg 171B preserve a record of the early history and adaptive radiation of the genus Eiffellithus. Seven distinct taxa are recognized and differentiated, with one previously named taxon (E. monechiae) emended and four new species described: E. praestigium, E. vonsali...

Late Paleocene and Early Eocene Paleoclimate Reconstructions: The Digital Leaf Physiognomy Approach

Biostratigraphy and paleoecology of Paleogen rocks based on calcareous nannofossil in Kafaz section, east Iran

In this study, the assemblage of calcareous nannofossils has been investigated in long and continuous deposits from a Kafaz section in Eastern Iran. A systematic study of calcareous nannofossils has indicated 39 nannofossils species. In order to the age determination of Kafaz's deposits, a revised zonation for the Eocene is used. Based on it, the Early-Middle Eocene deposits of Kafaz section is...

Biostratigraphy and paleoecology of Cretaceous rocks based on calcareous nannofossil in Sarayan section, East Iran

Calcareous nannofossil assemblages recovered from a long, continuous section have been described from the Sarayan region in Lut Block in east Iran. The marine Upper Cretaceous sediments of this section yield medium diverse and well-preserved calcareous nannofossil assemblages. A structural analysis of Upper Cretaceous calcareous nannofloras has revealed 30 nannofossil species. A revised zonatio...
