The Case for the Anthropocene Epoch Is Stronger Than the Case for the Holocene Epoch

Earth's Future, Volume 13, Issue 5, May 2025.
Abstract The recommendation that the Anthropocene be denoted as a geological epoch was recently rejected by the International Union of Geological Sciences. Here, we compare the scientific rationales presented for the Anthropocene, the Holocene and the six other epochs in the Cenozoic Era: the Pleistocene, the Pliocene, the Miocene, the Oligocene, the ...

South American Great Basin: Limnogeological analysis of the Salina del Bebedero Basin, Argentina (Late Pleistocene‐recent)

The Depositional Record, Volume 11, Issue 2, Page 739-763, April 2025.
. The Bebedero tectonic depression in San Luis province, Argentina, is a closed drainage basin that has formed as a result of block‐faulting and rifting processes. The Bebedero lake exhibits notable similarities to the endorheic watersheds of the western United States, particularly those of Death Valley, the Saline Valley and, to a lesser extent, the ...

Would Adding the Anthropocene to the Geologic Time Scale Matter?

AGU Advances, Volume 6, Issue 2, April 2025.
Abstract Abrupt planetary change forced by the cumulative and overwhelming impacts of human activities in the mid‐twentieth century supports a new geologic epoch, named after Anthropos, the agent of this change. This transformation extends well beyond Holocene norms and is identified in geologic records worldwide.

Palaeoecology of the Cenomanian amber forest of Sarthe (western France) [PDF]

, 2013
Cretaceous ambers have been discovered in France since the beginning of the 18th century. The best known are those from south-western France which are Late Albian-Early Cenomanian in age, but there are other important amber deposits in other regions ...

Traces de volcanisme explosif dans le Campanien pyrénéen aux alentours du stratotype de limite Campanien-Maastrichtien à Tercis (SO France, N Espagne). Repérage biostratigraphique avec une étude particulière du foraminifère Radotruncana calcarata [Traces of explosive volcanism in the Pyrenean Campanian around the Campanian-Maastrichtian boundary type section at Tercis (SW France, N Spain). Biostratigraphy with emphasis on the foraminifer Radotruncana calcarata]

Carnets de Géologie, 2010
Pyroclastic material including idiomorphic crystals of sanidine, biotite, and apatite, first identified in the type section at Tercis are contemporaneous with the Radotruncana calcarata (planktonic foraminifer) total range zone.

Reassessment of the iconic Oligo‐Miocene heterodont dolphin Squalodon: a redescription of the type species S. grateloupii

Papers in Palaeontology, Volume 11, Issue 2, March/April 2025.
Abstract Since its description in 1840, the toothed whale Squalodon was conceptualized as a transitional form between archaeocetes‐like Basilosaurus and the modern toothed whales (Odontoceti). The cranial morphology of Squalodon approximates that of modern odontocetes; however, their dental patterning more closely resembles that of archaeocetes ...

Nouvelles études micropaléontologiques sur le stratotype de la limite Campanien-Maastrichtien à Tercis (SO France) : les gilianelles (microproblematica) extraites par acétolyse [New micropalaeontological studies on the stratotype of the Campanian-Maastrichtian boundary at Tercis (SW France): the gilianelles (microproblematica) extracted through acetolysis]

Carnets de Géologie, 2006
The Campanian-Maastrichtian stratotype section at Tercis (SW France) consists mainly of hard calcareous levels. Their treatment using acetolysis left residues among which for the first time well-preserved free microfossils were obtained (These levels ...
