Miocene deep-water agglutinated foraminifera from the Lomonosov Ridge and the opening of the Fram Strait [PDF]

, 2009
Deep-water agglutinated Foraminifera (DWAF) were recovered from Miocene to Pliocene sediments in 103 samples from IODP Hole M0002A on the Lomonosov Ridge.

Sedimentation environment of the Cojimar Formation (Havana province) based on benthic foraminifera

Minería y Geología, 2022
Cojímar Formation, —Lower Miocene (upper part) to Middle Miocene (lower part)—, is a unit in Western Cuba well known for its extensive development and exposure outcrops. It has been widely used in bioestratigraphic studies.

Biostratigraphic and Geological Significance of Planktonic Foraminifera, Updated Second Edition [PDF]

, 2015
The role of fossil planktonic foraminifera as markers for biostratigraphical zonation and correlation underpins most drilling of marine sedimentary sequences and is key to hydrocarbon exploration.

Cold-seep fossil macrofaunal assemblages from Vestnesa Ridge, eastern Fram Strait, during the past 45 000 years

Polar Research, 2019
Four cores from 1200 m water depth from Vestnesa Ridge on the western Svalbard margin in the eastern Fram Strait were studied for their content of fossil macrofaunas.

Biostratigraphy of the Ruteh Formation at Harijan section (Central Alborz) northern Iran using foraminifera and conodont [PDF]

, 2009
In order to study the fossil contents of the Ruteh Formation for biostratigraphical purposes, the 200 meters thick section was sampled at Harijan section, Central Alborz. The sequence is mainly made up of limestone and shale's.

Foraminiferal morphogroups of the Early–Middle Cretaceous succession in northeastern Rafsanjan and their significance as palaeoenvironmental bioindicators [PDF]

Journal of Stratigraphy and Sedimentology Researches
Foraminiferal morphogroups reveal their responses to palaeoenvironmental and palaeoecological changes. The foraminiferal morphogroups of the early-mid Cretaceous in northeastern Rafsanjan have been investigated with an interest in palaeoenvironmental ...

Shallow-water benthic foraminifera as proxy for natural versus human-induced environmental change [PDF]

, 2007
Ecosystem composition and functioning is not only subjected to human-induced alterations, ecosystems also subjected to natural (e.g. climate-induced) variability.

Environmental DNA sheds new insight on molecular adaptation of foraminifera to temperature from laboratory‐controlled culture experiment

Ecology and Evolution
Foraminifera is the most important temperature proxy of the ocean on long time scales. However, the absence of temperature‐controlled experiments at different water depths hinders the advancement of paleotemperature reconstruction with foraminifera from ...

Does foraminiferal test size reflect changes in palaeoenvironmental conditions?—a case study from the southern Svalbard shelf

Polar Research, 2020
Although the environmental factors influencing the growth rate and reproduction of benthic foraminifera are known, the relationship between foraminifera test size and environmental variables remains unclear, especially on geological timescales.
