A morphogroup analysis of the upper Hauterivian-lower Barremian foraminiferal assemblages from the Agua de la Mula Member of the Agrio Formation (Neuquén Basin, Argentina) reveled six associations based on benthic foram...

Abstract The Eocene–Oligocene transition was the crucial turning point when Earth’s climate shifted to its current icehouse state. Understanding how the marine biosphere responded during this transition is not well-c...

Abstract Methane hydrate dissociation along continental margins has been widely associated with global carbon cycle perturbations and climate changes. However, the relationship between hydrate dynamics, carbon cycle dist...

The Late Quaternary North Sea basin represents a highly dynamic shelf system, altered by glaciations, deglaciations, and the recent Early Holocene marine transgression. However, detailed studies on the timing of the mari...

Abstract The chemical weathering of Earth's silicate rocks regulates the global climate. However, the exact role of continental weathering with orogenic building and island arc weathering with arc‐continent collisions ...

In order to characterize the diet of Astropecten brasiliensis and Luidia ludwigi scotti, the stomach content of both starfish species was analyzed. Starfishes were sampled for two years off Puerto Quequén coast in the B...

Latest Maastrichtian climate change caused by Deccan volcanism has been invoked as a cause of mass extinction at the Cretaceous-Paleogene (K-Pg) boundary (~66.0 Ma). Yet late Maastrichtian climate and ecological changes...

We investigate the use of Hg as a proxy for volcanism by studying four distal and two proximal sections in relation to the Deccan volcanic center, straddling the Cretaceous-Paleogene (KPg) boundary at (a) Højerup (Denma...

Over the past four decades, global actualistic taphonomy studies have grown significantly, driven by increased interest in present day patterns and processes of fossilization. South America has mirrored this trend, thoug...

The Argentine Continental Margin (ACM) comprises one of the largest contourite depositional systems worldwide, with evidences of strong gravitational downslope and alongslope sediment transport processes. Strong bottom c...

The IntCal09 and Marine09 radiocarbon calibration curves have been revised utilizing newly available and updated data sets from 14 C measurements on tree rings, plant macrofossils, speleothems, corals, and foraminifera. ...
