An “Instructive” Bibliography of the Foraminifera [PDF]

open access: greenNature, 1888
UNDER the title of “The (!) Bibliography of the Foraminifera,” a remarkable production was published by Mr. Anthony Woodward in the Fourteenth Annual Report of the Geographical and Natural History Survey of Minnesota (St. Paul, 1886), and the work has lately been followed by a supplement—one of a series—in the Journal of the New York Microscopical ...

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 229-246., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Biocalcification in porcelaneous foraminifera

open access: yeseLife, 2023
Living organisms control the formation of mineral skeletons and other structures through biomineralization. Major phylogenetic groups usually consistently follow a single biomineralization pathway. Foraminifera, which are very efficient marine calcifiers, making a substantial contribution to global carbonate production and global carbon sequestration ...

Origin of the foraminifera. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1995
We report nuclear small-subunit rDNA sequences for two species of the benthic foraminifer Ammonia. Because of their abundance in present and past seas, the foraminifera are a very important group of organisms used in a wide range of geologic studies; however, the ancestry of this group was, until now, unknown.

Subsurface and Infaunal Foraminifera of Kemaman- Chukai Mangrove Swamps, East Coast Peninsular Malaysia

open access: yesOpen Quaternary, 2021
This study analysed the distribution and abundance of dead and live (Rose Bengal stained) infaunal foraminifera from three short cores taken at three locations in the mangrove swamps of Kemaman-Chukai, Terengganu, Malaysia.

The evolution of early Foraminifera [PDF]

open access: yesProceedings of the National Academy of Sciences, 2003
Fossil Foraminifera appear in the Early Cambrian, at about the same time as the first skeletonized metazoans. However, due to the inadequate preservation of early unilocular (single-chambered) foraminiferal tests and difficulties in their identification, the evolution of early foraminifers is poorly understood. By using molecular data from a wide range

Biomineralization in perforate foraminifera [PDF]

open access: yesEarth-Science Reviews, 2014
In this paper, we review the current understanding of biomineralization in perforate foraminifera. Ideas on the mechanisms responsible for the flux of Ca2 + and inorganic carbon from seawater into the test were originally based on light and electron microscopic observations of calcifying foraminifera.

Development of freeze-thaw processing technique for disaggregation of indurated mudrocks and enhanced recovery of calcareous microfossils [PDF]

open access: yes, 2014
Microfossil extraction from indurated mudrocks is widely acknowledged as challenging, especially for foraminifera. Here we report development of the freeze–thaw extraction method through the addition of rapid heating, detergent and ultrasound stages.

Planktonic foraminifera fluxes and their response to the Asian Monsoon: insights from the Maldives, Indian Ocean

open access: yesFrontiers in Earth Science, 2023
This study describes seasonal changes in the fluxes of planktonic foraminifera in response to changes in environmental conditions during the Asian Monsoon.

Coupled Mg/Ca and clumped isotope analyses of foraminifera provide consistent water temperatures [PDF]

open access: yes, 2018
The reliable determination of past seawater temperature is fundamental to paleoclimate studies. We test the robustness of two paleotemperature proxies by combining Mg/Ca and clumped isotopes (Δ47) on the same specimens of core top planktonic foraminifera.
