The biostratigraphic correlation scheme of Upper Cretaceous multicoloured claystones in the Polish Romanian. External Carpathians using agglutinated deep-water foraminifers can be extended to onshore localities in the Gibraltar Arch area (Morocco, Spain) and DSDP/ODP sites in the North Atlantic. In all studied areas, taxonomic turnovers in deep-water agglutinated foraminifers are observed at the Cenomanian-Turonian boundary and in the early/middle Campanian. Additionally, a remarkable decrease in abundance and diversity of benthic agglutinated foraminifers is observed at the same levels in continuous sections of North Atlantic DSDP sites. These datum levels correspond to inter-regional and time-constant palaeoceanographic events, and may facilitate the direct correlation of the biozonation of agglutinated foraminifers to the standard geomagnetic polarity time scale.

Deep-water agglutinated Foraminifera (DWAF) display potential for correlating pelagic (calcareous and non-calcareous) and flysch environments. This is illustrated by an example from Sites 765 and 261 on the Argo Abyssal Plain. A working zonation based on DWAF has been developed for Lower Cretaceous flysch sequences of the Polish Carpathians, but this zonal scheme has not been tested in other areas of the Tethys. No zonation has yet been developed for abyssal oceanic DWAF. The challenge for the future, under the auspices of Project 262, is to test the existing zonation in other regions and develop a widely applicable biochronology for integration into a general Tethyan biochronological correlation scheme.

Benthic foraminifers were studied in 99 samples collected from the lower 200 m of Hole 765C.The studied section ranges from the Tithonian to Aptian, and benthic foraminifers can be subdivided into five assemblages on the basis of faunal diversity and stratigraphic ranges of distinctive species.Compared with deep-water assemblages from Atlantic DSDP sites and Poland, assemblages from the Argo Abyssal Plain display a higher diversity of agglutinated forms, which comprise the autochthonous assemblages.Assemblages at the base of Hole 765C are wholly composed of agglutinated forms, reflecting deposition beneath the carbonate compensation depth (CCD).Most calcareous benthic species are found in turbidite layers, and the presence of an upper Valanginian Praedorothia praehauteriviana Assemblage may indicate deposition at or just below the CCD.The P. praehauteriviana Assemblage from Hole 765C is the temporal equivalent of similar assemblages from DSDP Holes 534A, 416A, 370, 105, and 101 in the Atlantic Ocean and Hole 306 in the Pacific Ocean.Stratigraphic ranges of cosmopolitan agglutinated species at Site 765 generally overlap with their reported ranges in the Atlantic and in the bathyal flysch sequences of the Carpathians; however, several species from Hole 765C have not been previously reported from Uppermost Jurassic to Lower Cretaceous abyssal sediments.

Two new species of the lituolid genus Phenacophragma, characterized by intracameral hemiseptae, are described from "flysch-type" agglutinated foraminiferal faunas. Phenacophragma beckmanni, n. sp. occurs in the Paleocene Lizard Springs formation of Trinidad and in Paleocene to middle Eocene sediments of the Polish Carpathians. Phenacophragma elegans, n. sp. has been observed only in Trinidad.

The sedimentologie and tectonic history of the Silesian Flysch Basin is reviewed and a stratigraphic scheme is presented for the Polish Outer Carpathians. The paleoecology of Tithonian to Oligocene benthic foraminiferal assemblages in the Silesian Basin is discussed, and stratigraphic ranges of 45 important species of agglutinated foraminifera are reported in terms of their occurrence in major lithostratigraphic units.
