DEEP WATER AGGLUTINATED FORAMINIFERA FROM THE JURASSIC/CRETACEOUS BOUNDARY AND PALEOENVIRONMENTAL SETTINGS OF THE MAIOLICA TYPE FACIES FROM THE CZORSTYN RIDGE (PIENINY KLIPPEN BELT, WESTERN CARPATHIANS)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2017
Deep-water carbonates deposited on the Czorstyn elevated ridge of the Pieniny Klippen Belt paleogeographic domain record changes in agglutinated foraminifera morphogroups through the J/K boundary interval at the Erdútsky kostol section.

Forabot: Automated Planktic Foraminifera Isolation and Imaging

open access: yesGeochemistry, Geophysics, Geosystems, 2022
Physical inspection and sorting of foraminifera is a necessity in many research labs, as foraminifera serve as paleoenvironmental and chronostratigraphic indicators.

Symbiont 'bleaching' in planktic foraminifera during the Middle Eocene Climatic Optimum [PDF]

open access: yes, 2013
Many genera of modern planktic foraminifera are adapted to nutrient-poor (oligotrophic) surface waters by hosting photosynthetic symbionts, but it is unknown how they will respond to future changes in ocean temperature and acidity.

PALEOBIOGEOGRAPHY OF SOME EGYPTIAN AND PAKISTANIAN BENTHIC FORAMINIFERAL SPECIES IN THE NORTHERN TETHYS [PDF]

open access: yesEarth Sciences Pakistan, 2021
Twenty-one benthic foraminiferal species were originally erected from the Southern Tethys, 13 species from Egypt, and 8 species from Pakistan. Some of these species were recorded from different localities in the Northern Tethys: France, Spain, Italy ...

Foraminifera On The Beach Of Malalayang Dua

open access: yesJurnal Ilmiah Platax, 2018
Beach as one on the landform that reflects the work of hydro-oceanographic factors, generally in the form of loose sedimentary material. Loose sediment is a collection of organic and inorganic particles that accumulate widely and are irregular in shape.

PALEONTOLOGY AND PALEOGEOGRAPHY OF THE TETHYAN EARLY PALEOGENE ROTALIID BENTHIC FORAMINIFERAL PAKISTANIAN GENUS ORNATANOMALINA AND OTHER RELATED GENERA [PDF]

open access: yesEarth Sciences Pakistan, 2021
Six Early Paleogene small Rotaliid benthic foraminiferal species of the genus Ornatanomalina Haque are common in Pakistan and some of them are recorded from some localities in the Southern Tethys (Iraq, Qatar, United Arab Emirates, Nigeria), as well as ...

Facies and paleoenvironmental reconstruction of Early–Middle Miocene deposits in the north-west of the Zagros Basin, Iran

open access: yesGeologica Carpathica, 2019
Facies analysis and paleoenvironmental reconstruction of the Burdigalian to Langhian Asmari Formation, outcropping in the Khorram Abad Anticline, in the north-west of the Zagros Basin allow us to interpret the carbonate ramp history during the Early ...

The niche of benthic foraminifera, critical thresholds and proxies [PDF]

open access: yes, 2001
Ecological studies of benthic foraminifera are carried out to explain patterns of distribution and the dynamics of communities. They are also used to provide data to establish proxy relationships with selected factors.
