(PDF) The Mesozoic planktonic foraminifera: The Cretaceous Taxanomically, the Cretaceous planktonic foraminifera are here divided into two orders: the Globigerinida and the Heterohelicida. It is proposed that the former are best divided into three main (PDF) Late Cretaceous Biostratigraphy Planktonic ... PDF Available. Late Cretaceous Biostratigraphy Planktonic Foraminifera of the Farokhi Formation, Iran. Upper Cretaceous planktonic Foraminifera from the Western Gulf Coastal Plain. Article. Biozonation and Paleobathymetry on Foraminifera Upper ... In order to indicate the ancient depth of Upper Cretaceous at this time, planktonic and benthic foraminifera were studied. The percentage of the total planktonic foraminifera to the whole sample of foraminifera after the removal of indwell benthic foraminifera (%P*) using the formulaD = e(3.58718 + (0.03534 P*× %)) was identified

Upper Cretaceous Foraminifera from Japan Upper Cretaceous Foraminifera from Japan KIYOSHI ASANO1 IN THIS PAPER the discovery in Japan of smaller Foraminifera from the Upper Creta­ ceous strata is recorded for the firsi: time. This contribution, in addition to its specific bio­ stratigraphicapplication in Japan, has further interest by … Cretaceous planktonic foraminiferal zonation Radiometric data and phylogenetic analysis of Cretaceous planktonic foraminifera suggest that the Cretaceous be divided into three epochs rather than two. Primitive globigerines occur in the Lower Cretaceous, single-keeled Rotalipora faunas that of the Upper Cretaceous (text-figure 1) and the sec- ond was that of the Paleocene - Middle 17. PLANKTONIC FORAMINIFERA FROM THE UPPER … A detailed list of the planktonic foraminifera and a few benthonic smaller and larger foraminifera found in the Upper Cretaceous at Site 98 is given on the distribution-chart. The following remarks are therefore restricted to the comments needed for the understand-ing of this chart and to a few ambiguous species. UPPER CRETACEOUS FORAMINIFERA TRINIDAD

Upper Campanian(?)-lower Danian planktonic foraminiferal ... Description The 140 m Dababaiya Corehole (DBQ), drilled in the Dababiya Quarry about 35 km south of Luxor, Upper Nile Valley, Egypt, spans the stratigraphic interval from upper Campanian/lower Maastrichtian (the Globotruncana aegyptiaca Zone) to the lower Eocene. This study is devoted to an investigation of the planktonic and benthic foraminifera of the Upper Cretaceous (Maastrichtian) and Biozonation and Paleobathymetry on Foraminifera Upper ... In this study Late Cretaceous stratum in central Iran, Baharestan section in Isfahan area, was evaluated by biozonation and paleobathymetry. These sediments have 89 meters thick, and strata have been formed of marl and marl limestone. In order to indicate the ancient depth of Upper Cretaceous at this time, planktonic and benthic foraminifera were studied. Original article New biostratigraphic data from Cretaceous ...

The Upper Cretaceous strata of the Gulf Coast region of México, Texas, and southwestern Arkansas contain rich, abundant, well-preserved, and, hitherto, poorly studied assemblages of … Cretaceous (Albian-Cenomanian) planktonic Foraminifera in ...
