Calcareous Nannoplankton Fossils and their Stratigraphic Meaning

Journal of Geography (Chigaku Zasshi), 1978
Modern calcareous nannoplanktons have an important role in marine food chain as a primary producelr. Fossils nannoplankton played an important part of the Mesozoic and Cenozoic biological world, and are now accepted as a very useful and accurate index fossil from the Jurassic to Recent Period.In this article recent advance of nannoplankton ...

Relationship and Source of Whitings Used as a Painting Ground in Icons From Polish Museum Collections Based on Their Calcareous Nannofossil Content

Archaeometry, Volume 68, Issue 1, Page 132-143, February 2026.
ABSTRACT In icon painting, chalk whiting is key to creating a gesso ground, providing a smooth, absorbent surface for paint. Calcareous nannofossils, tiny marine skeletons found in chalk, are an ideal tool for analyzing the origin of an icon's chalk ground, often the only reliable information about where the icon came from.

Sea Surface Temperature and Salinity Changes in the Easternmost Mediterranean During the Pre‐Evaporitic Messinian Controlled by the Restriction at Gibraltar

Paleoceanography and Paleoclimatology, Volume 41, Issue 1, January 2026.
Abstract During the latest Miocene, the Mediterranean Basin was affected by extreme paleoceanographic and paleoenvironmental changes culminating with evaporite (gypsum and halite) formation during the Messinian Salinity Crisis (MSC: 5.97–5.33 Ma).

MIDDLE MIOCENE DROWNED RAMP IN THE VICINITY OF MARIJA BISTRICA (NORTHERN CROATIA)

Rudarsko-geološko-naftni Zbornik, 2018
Fossiliferous Middle Miocene deposits from the surroundings of Marija Bistrica (north-east of Zagreb) transgressively overly older pre-Cenozoic bedrocks. Fossils from shallow marine environments are in most cases preserved as bioclasts, while deep marine

CALCAREOUS NANNOPLANKTON OF APTIAN OF MOUNTINE CRIMEA

Collection of Scientific Works of the Institute of Geological Sciences of the NAS of Ukraine, 2013
Вперше для Гірського Крима наведені дані про стратиграфічне поширення вапняного нанопланктону з аптських відкладів. Показана можливість виділення двох нанопланктонних зон: Chiastozygus litterarius (нижній апт) та Rhagodiscus angustus (средній-верхній апт). Межа апту та альбу встановлена за появою Prediscosphaera cretacea.

A model for the concomitant early formation of dolomite and fibrous clays in coastal bay systems: Evidence from the Eocene (Paris Basin, France)

Sedimentology, Volume 72, Issue 6, Page 1860-1898, October 2025.
ABSTRACT Detailed analysis of Lutetian–Bartonian deposits in the Paris Basin (‘Marnes et Caillasses’ Formation) provides new evidence of concomitant magnesian fibrous clays (palygorskite and sepiolite) and early microcrystalline dolomite. Although relatively uncommon in sedimentary archives, palygorskite and sepiolite are found in a wide range of ...
