Lithostratigraphy and biostratigraphy sometimes provide contradictory interpretations,
especially when trying to establish a chrono-lithological boundary between two reservoir …

Forty-three planktic foraminifera samples from the Themed section (East Central Sinai;
Egypt) spanning the Zone Parvularugoglobigerina eugubina (Pα) to the Subzone Acarinina …

In the present study, we document paleoenvironmental change across the Danian–
Selandian transition (planktic foraminiferal interval P2–P3b; calcareous nannofossil Zone …

The P3a/P3b subzonal boundary is delineated by the lowest occurrence of Igorina albeari.
Using literature, identification of the first representatives of I. albeari appeared to be very …

A regional unconformity at the Danian–Selandian (D/S) boundary is recorded in Western
Desert, Egypt, based upon field study, biostratigraphic analyses and paleoenvironmental …

Three new genera of coccolithophores are introduced and one genus is emended. Six new
species are described. They are part of the so-called first radiation of the fasciculiths that …

To reconstruct the paleoclimate in North Africa during the Paleocene, the calcareous
nannofossils were quantitatively analyzed at higher resolution from the stratigraphic …

A detailed study of the calcareous nannofossil assemblages of latest Danian to early
Selandian age from Wadi Qena (the Qreiya-1, Qreiya-2, and Araas sections) in the central …

The variations in assemblages of calcareous nannofossils are tracked in the Dakhla and
Tarawan Formations exposed at Gebel Nezzazat (central Sinai, Egypt). Five calcareous …

The present study concerns with the nannofossil biostratigraphy of the Paleocene-lower
