Paleogene benthic foraminifer biostratigraphy and paleoecology at Site 647, Southern Labrador Sea [PDF]
, 1989 Benthic foraminifers were examined from the Paleogene of Ocean Drilling Program (ODP) Site 647 and Deep Sea Drilling Program (DSDP) Site 112 in the southern Labrador Sea.

The first evidence of marine Badenian transgression near Koceljeva (central Paratethys, Western Serbia) [PDF]
Geološki Anali Balkanskoga Poluostrva, 2019 This paper presents the first detailed biostratigraphic investigation of deposits cropping out in stream Sumijevac near Koceljeva (western Serbia). The most important fossil communities and their significance are presented.

Phenotypic Evolution in a Cretaceous Foraminifer [PDF]
Evolution, 1982 Statistically well-documented sequences of fossil species are rare, as has been observed, for example, by Eldredge and Gould (1972), Boucot (1978) and Dodson and Hallam (1977). Rapid advances in theoretical paleontology made over the last few years have, however, made it imperative that the many new and exciting theories we now have at our disposal be ...

The Middle Carboniferous Boundary in the North of Pay-Khoy – Correlation between the Shallow- and Deep-Water Sequences [PDF]
Учёные записки Казанского университета: Серия Естественные науки, 2017 The paper considers the Lower-Middle Carboniferous boundary interval in the sections of the Pay-Khoy carbonate parautochthone (shallow-water facies) and the Kara slate allochthone (deep-water facies) with respect to the boundary tracing criteria.

Geologica Carpathica, 2017 Thorough study of foraminifers, ostracods and dinoflagellate remnants from the Zavodskaya Balka and Koklyuk sections helps to characterize the detailed biostratigraphic division of the Berriasian / Valanginian boundary sequence in the Feodosiya district ...

Evidence for complete denitrification in a benthic foraminifer [PDF]
Nature, 2006 Benthic foraminifera are unicellular eukaryotes found abundantly in many types of marine sediments. Many species survive and possibly reproduce in anoxic habitats, but sustainable anaerobic metabolism has not been previously described. Here we demonstrate that the foraminifer Globobulimina pseudospinescens accumulates intracellular nitrate stores and ...

The Cretaceous/Paleogene (K/Pg) boundary in the Mezdra and Lyutidol syncline, Vratza District (West-Fore Balkan, Bulgaria) [PDF]
Geološki Anali Balkanskoga Poluostrva, 2006 This paper discusses the unjustified assignment (based on calcareous nannofossils) of a large portion of the Maastrichtian strata in the Mezdra and Lyutidol synclines (West Fore Balkan, Bulgaria) to the Paleogene.
