New robertinid foraminifers from the Early Jurassic of Adnet, Austria and their evolutionary importance [PDF]
Acta Palaeontologica Polonica, 2016 New benthic multichambered foraminifers have been discovered in the Hettangian–Sinemurian of the Northern Calcareous Alps (Adnet, Salzburg, Austria). Originally aragonitic, these forms are completely recrystallized but the early impregnation of their ...

Geologica Carpathica, 2017 Thorough study of foraminifers, ostracods and dinoflagellate remnants from the Zavodskaya Balka and Koklyuk sections helps to characterize the detailed biostratigraphic division of the Berriasian / Valanginian boundary sequence in the Feodosiya district ...

Journal 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

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

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

Ontogenetic disparity in early planktic foraminifers
Journal of Micropalaeontology, 2020 . Changes in morphology during ontogeny can have profound impacts on the physiology and biology of a species. Studies of ontogenetic disparity through time are rare because of the lack of preservation of developmental stages in the fossil record. As they

Geosciences, 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,
