Foraminifera from the Tepetate Formation (Heim) at Las Pocitas, Baja California Sur, Mexico

Ciencias Marinas, 2008
In order to constrain the age and depositional paleoenvironment of the Tepetate Formation, benthic and planktonic foraminifera were analyzed in samples recovered from an exploration well located at Las Pocitas, Baja California Sur, Mexico.

Complex marine ecological response during the Eocene-Oligocene revealed by global foraminiferal record. [PDF]

Nat Commun
The Eocene–Oligocene transition was the crucial turning point when Earth’s climate shifted to its current icehouse state. Understanding how the marine biosphere responded during this transition is not well-constrained, appearing as a simple extinction ...

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

Geologica 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 ...

A resolution for the coiling direction paradox in Neogloboquadrina pachyderma. [PDF]

, 2006
We present new data on genotypic differences and biogeographic distribution of coiling types in the living planktonic foraminiferal morphospecies Neogloboquadrina pachyderma. The genetic evidence demonstrates that coiling direction in N.

Palaeoenvironmental, palaeoecological and palaeobiogeographical implications of mixed fresh water and brackish marine assemblages from the Cretaceous-Palaeogene Deccan intertrappean beds at Jhilmili, Chhindwara District, central India

Revista Mexicana de Ciencias Geológicas, 2018
The Deccan infra- and intertrappeans volcano-sedimentary sequences have been considered as terrestrial to fluvio-lacustrine deposits. Presence of planktonic foraminifera and brackish water ostracods in the Jhilmili basal Danian intertrappean beds ...

STRATIGRAPHY AND MICROFACIES STUDIES ON SOME TERTIARY ROCKS IN NORTH GALALA PLATEAU, NORTH EASTERN DESERT, EGYPT [PDF]

Delta Journal of Science, 2006
The early and middle Eocene successions of Wadi EL Qena (Sec. II) and Wadi El Agramiya (Sec. I) surface sections in west El Galala El-Baharia area, north Eastern Desert, were examined in detail.

Projected impacts of climate change and ocean acidification on the global biogeography of planktonic Foraminifera [PDF]

Biogeosciences, 2015
Planktonic Foraminifera are a major contributor to the deep carbonate flux and their microfossil deposits form one of the richest databases for reconstructing paleoenvironments, particularly through changes in their taxonomic and shell composition. Using

Integrated stratigraphy of the Waitakian-Otaian Stage boundary stratotype, Early Miocene, New Zealand

, 1999
The base of the type section of the Otaian Stage at Bluecliffs, South Canterbury, is recognised as the stratotype for the boundary between the Waitakian and Otaian Stages.

Planktonic Foraminifera Biostratigraphy Of Taeno Limestone, Ambon, Maluku Province, Indonesia

JGEET: Journal of Geoscience, Engineering, Environment and Technology
The limestone became exposed to the surface because of an uplift event during the Quaternary period. This study aims to determine the age of limestone outcrops in the Taeno Traverse using planktonic foraminifera.
