A section from the southern (Austro-Alpine Northern Calcareous Alps) margin of the Penninic Ocean in the NW Tethys realm of Late Campanian age is investigated stratigraphically. Plankton foraminifer and nannofossil biostratigraphy designate the presence of the Globotruncana ventricosa Zone and the Radotruncana (Globotruncanita) calcarata Zone, and standard nannofossil zones CC21-UC15cTP and CC2...

Coccolithophores, common primary producers in Mesozoic, Cenozoic, and present oceans, are significant components of the earth’s biogeochemical cycles. Being most productive calcifying organism on earth, their carbonate oozes play a major role fixing CO2, thereby forming important long-term CO2 sink throughout last 100 Ma. Our understanding fossil ancestors is mainly based data from chalk sequen...

Dinosaur fossils from the latest Cretaceous (Campanian–Maastrichtian) of Africa and Arabian Peninsula are rare. Most discoveries to date have consisted limited that precluded detailed phylogenetic paleobiogeographic interpretations. Fortunately, recent such as informative Egyptian titanosaurian sauropod dinosaur Mansourasaurus shahinae beginning address these long-standing issues. Here we descr...

This study presents the first integrated, high-resolution stratigraphic analysis of a large area Cretaceous Western Interior Basin in Alberta (western Canada), providing new tools to discriminate sedimentary processes and patterns transgressive-regressive (T-R) cycles correlative marine non-marine domains. We integrate gamma ray well-log analysis, measured sections, paleontological data determi...

The Kometan Formation is widely spread in northeastern Iraq and mostly composed of deep marine carbonates, with a predominance planktonic foraminiferal assemblages throughout its sequences. Two outcrop sections, Smaquli Tabin, were chosen to study the biostratigraphy Formation. identified 32 species belonging 12 genera. According stratigraphic distribution relative foraminifera assemblages, dem...

Figure 1. A: Map of Charleston-Nebo salient and northernmost Book Cliffs showing rock units, thrust faults (dashed where buried), key seismic coverage (gray lines), measured stratigraphic sections (1–7; 8 is location of additional Blackhawk sandstone samples), and wells. Rock units: KTs—Cretaceous–Tertiary strata (North Horn and younger formations), Kmv—Cretaceous Mesaverde Group (Blackhawk, Ca...

A Detailed Calcareous nannofossil study conducted on the Bekhme Formation that is cropped out at Southern limb of Bekhere anticline, eastern ward Dohuk city near Bajlur village, northern Iraq. The composed marly limestone, Organic limestone and fossiliferous limestone. nannopaleontological classification these calcareous nannofossils led us to determine thirty-four genus/species belonging nine ...
