Marine Anoxia and Ocean Acidification During the End‐Permian Extinction

open access: yesGeophysical Monograph Series, Page 325-340., 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.

Some Late Cretaceous agglutinated foraminifers from the Northern outskirts of Donbas, Ukraine

open access: yesGeo&Bio, 2023
The article describes four species of agglutinated foraminifers belonging to three genera (Verneuilina, Orbignyna, and Spiroplectammina) three superfamilies (Verneuilinoidea, Ataxophragmoidea, and Spiroplectamminoidea) and two orders (Ataxophragmiida and

Palaeoenvironmental changes based on foraminifera during the late Holocene at the Beagle Channel, Argentina

open access: yesAnais da Academia Brasileira de Ciências, 2022
A foraminiferal faunal study was carried out in a Holocene marine section from Arroyo Baliza, located on the northwest coast of the Beagle Channel, to contribute to the knowledge of the palaeoenvironmental conditions during the marine Holocene event ...

Past Analogues of Deoxygenation Events in the Mediterranean Sea: A Tool to Constrain Future Impacts

open access: yesJournal of Marine Science and Engineering, 2023
Human-induced carbon emissions are altering the modern climate, with severe repercussions on ecosystems. Among others, anthropogenic pressure is causing deoxygenation of the bottom water, with the widespread establishment of hypoxic zones in several ...

Foraminifer or Sponge? [PDF]

open access: yesNature, 1893
UNDER the above heading in last week's NATURE Dr. Hanitsch briefly draws our attention to Mr. A. Goes' report on the deep sea organisms procured by Prof. Agassiz in the American tropical Pacific, which he describes as Arenaceous Foraminifera, with the name Neusina Agassizi.

Upper Cretaceous, K/T boundary, and Paleocene agglutinated foraminifers from Hole 959D (Côte d'Ivoire-Ghana Transform Margin) [PDF]

open access: yes, 1998
Upper Cretaceous agglutinated foraminifer assemblages from Hole 959D of Ocean Drilling Program (ODP) Leg 159, Côte d’Ivoire-Ghana Transform Margin, reflect the subsidence history and paleoceanography of the widening equatorial Atlantic gateway.

Ostracod and Foraminifer Responses to Late Pleistocene–Holocene Volcanic Activity in Northern Victoria Land as Recorded in Ross Sea (Antarctica) Marine Sediments

open access: yesGeosciences, 2023
The impacts on ostracods and foraminifers caused by three Late Quaternary ashfalls of different intensities and recovered in the ANTA02-NW2 core sediments (Drygalski Basin, western Ross Sea) were analysed for the first time. Albeit with different timing,

Biostratigraphy of Eocene to Oligocene deep-water agglutinated foraminifers in the red clays from Site 767, Celebes Sea [PDF]

open access: yes, 1991
Deep-water agglutinated foraminifers were examined from reddish brown claystones comprising lithologic Unit 4 of Ocean Drilling Program Holes 767B and 767C. The biostratigraphy of deep-water agglutinated foraminifers in this unit indicates an Eocene to

Diversity patterns and palaeobiogeographical relationships of latest Devonian–Lower Carboniferous foraminifers from South China: What is global, what is local?

open access: yesJournal of Palaeogeography, 2014
During latest Devonian and early Carboniferous times, calcareous foraminifers were abundant, widely distributed, and showed the most rapid rate of evolution in the shallow-sea deposits. These factors, especially their fast phylogenetic changes, make them
