Abstract The Paleocene‐Eocene thermal maximum (PETM, ∼56 Ma) is marked by a massive and rapid rise in atmospheric CO2 and ∼5°C of global warming. It is globally characterized by a negative carbon isotope excursion (CIE), and, at least locally, is preceded by a pre‐onset excursion (POE).

Abstract Long‐term rates of crustal uplift in southern Calabria and NE Sicily are incompletely understood due to limited information about the age of marine terraces at 1.0–1.3 km above sea level (asl). This study provides a new constraint on high‐elevation terrace ages through integrated analysis of geochronology, stratigraphy, shoreline modeling, and

A new cephalopod find in the Eocene beds near Grdoselo in Istria, Croatia
The article presents a cast fossil of a cephalopod found in sandy limestones (packstones) of Eocene age nearGrdoselo in Central Istria. The phragmocone remains most probably belong to the nautilid species Eutrephoceras(Simplicioceras) centrale (Sowerby ...

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.

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).
