Testing for ecophenotypic variation in a benthic foraminifer
Lethaia, 1983A method for identifying ecophenotypic variants is tested, using two morphological variants of the benthic foraminifer Reophax dentaliniformis Brady from the Baltic Sea. Results show that the example does not correspond to the model for ecophenotypic variation.

Cretaceous bathymetric distribution of benthic foraminifers
The Journal of Foraminiferal Research, 1972Model based on comparison with Recent forms, numerical analysis of depth of restricted genera, overlapping ranges of indicative species, faunal diversity and abundance ...

A review of benthic foraminifers and ostracodes of the Antalya coast
Micropaleontology, 2008We studied benthic foraminifer and ostracod faunas from the Southwestern coasts of Antalya (Turkey) in 227 sediment samples collected by SCUBA divers in July and August, 2002. We identified 50 foraminifer genera and 96 species, some of which contained numerous large specimens.

Application of LP-ICP-MS to benthic foraminifers
Geochimica et Cosmochimica Acta, 1995Abstract A laser microprobe coupled with an inductively coupled plasma mass spectrometer (LP-ICP-MS) was used to determine Mg, Mn, Sr, and Ba contents of benthic foraminifers in the solid state. Calcite shells of Cibicides wuellerstorfi, Oridorsalis umbonatus, Pyrgo spp., and aragonite tests of Hoeglundina elegans, which were taken from the surface ...

Assemblages of benthic foraminifers in the White Sea
Oceanology, 2009Based upon the composition of the dominant species of benthic foraminifers in the bottom sediments sampled at 50 sampling stations in the White Sea, their six assemblages (communities) were defined and mapped. The ranges of these communities depend on the environmental factors determined by the bathymetric, latitudinal, and circum-continental sea ...

Benthic foraminifer communities of the Persian Gulf
Oceanology, 2010Eighteen types of benthic foraminifer communities inhabiting depths of 0–200 m are described for the Persian Gulf including the analysis of 269 sampling sites. The species area is mostly localized by the geographical position and bathymetrical features, including the water masses advection, the upwelling, the river discharge, and the concentrations of ...

BORINGS IN LARGER BENTHIC FORAMINIFERS FROM TURKEY AND THEIR PALEOENVIRONMENTAL SIGNIFICANCE
The Journal of Foraminiferal Research, 2006Cretaceous/Paleogene outcrops of Turkey provide important areas for the study of trace fossils on larger benthic foraminiferal tests such as Orbitoides and Loftusia from the Maastrichtian, and Nummulites, Assilina and Discocyclina from the Eocene.

Recent Benthic Foraminifers from the South Atlantic Shelf of Argentina
Journal of Foraminiferal Research, 2018Abstract The aim of this study was to determine foraminiferal associations from recent sediments of Argentina's continental shelf (39–41ºS, 59–61ºW; 11–70 m) and assess their relationship to physicochemical parameters. From 20 samples, all dominated by sandy sediments (>80% sand), 44 species of foraminifers were identified, most ...

Test ultrastructure of some living benthic foraminifers
Lethaia, 1974Development of test ultrastructure through ontogeny is traced in four living species from the foraminiferal families Bolivinitidae and Caucasinidae. Test construction conforms in general to the monolomellar concept, but differs in having double pore membranes between consecutive calcitic lamellae and in maintaining a nearly consistent wall thickness ...

Cenozoic Deep-Water Benthic Foraminifers: ABSTRACT
AAPG Bulletin, 1981Cenozoic deep water deposits have yielded rich and diversified faunas of benthic formaminifers. From still limited data, it is clear than these faunas were depth stratified and that most species were cosmopolitan in distribution. The wide distribution and species richness, together with faunal turnover, which in places was very abrupt, points to great ...
