Dental Microwear and Diets of Late Miocene Primates From Rudabánya, Hungary

American Journal of Biological Anthropology, Volume 188, Issue 1, September 2025.
ABSTRACT Objectives This study focuses on a dental microwear texture analysis of European pliopithecids and dryopithecins from the Miocene primate site of Rudabánya, Hungary. The goal is to determine whether these taxa, found in part together in the same deposits, differed in their food preferences, or at least consumed, on a daily basis, in a manner ...

Past aridity and dust drove biodiversity crises and altered pollination in the ancient gymnosperm Ephedra (Gnetales)

Biological Reviews, Volume 100, Issue 4, Page 1680-1697, August 2025.
ABSTRACT The long‐term effects of present‐day climate change on pollination are unquantified. However, distinguishing climatic drivers of ancient changes in pollination could provide valuable insights into biotic responses to near‐future climate states.

Changes of Poleward Oceanic Heat and Salt Transport Associated With the Central Eurasian Seaway During the Early Paleogene

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract During the early Paleogene, the Arctic Ocean existed in a warm yet restricted freshwater regime, with episodic strong freshening leading to proliferation of the freshwater‐adapted Azolla at basal middle Eocene times (49–48 Ma). The Kara Strait, located between the Arctic Ocean and the West Siberian Sea (WSS), facilitated an open central ...

Oligocene archaeomonad stomatocysts from the Polish Central Paratethys

Acta Palaeontologica Polonica
An unanticipated diversity of archaeomonad stomatocysts intermixed with marine plankton including diatoms, silicoflagellates, parmaleans and individual siliceous protistan scales was encountered in Rupelian diatomites from the Central Paratethys. In this

A Model Based Study of the Emergence of North Atlantic Deep Water During the Cenozoic: A Tale of Geological and Climatic Forcings

Paleoceanography and Paleoclimatology, Volume 40, Issue 5, May 2025.
Abstract The North Atlantic Deep Water (NADW) is a key component of modern climate systems, redistributing heat from equatorial to polar regions and contributing to the Atlantic Meridional Overturning Circulation. However, the timing of its emergence and the mechanisms driving its formation remain uncertain.

Structurally Controlled Silica Precipitation Within Multi‐Stage Fault Damage Zones During the Rifting of the Pannonian Basin

Basin Research, Volume 37, Issue 3, May/June 2025.
Evolution of deformation mechanism and associated silica precipitation with respect to stratigraphic and burial position during syn‐rift phases. ABSTRACT Development of brittle fracture zones as passages for fluid migration within the shallow crust results in substantial petrophysical and rheological changes that strongly influence deformation ...

Silicoflagellates and other siliceous micro- and nannofossils from Rupelian diatomites, southeastern Poland

Plant and Fungal Systematics
The Eocene-Oligocene Transition is one of the major stages of the Cenozoic reshaping of the world oceans with associated changes in climate, of ocean coastlines and circulation patterns.

Porgy fish teeth in Miocene marl from Mastni hrib near Škocjan, Slovenia

Geologija, 2014
The article discusses fossil porgy fish teeth found in Middle Miocene (Badenian) sandy marl from Mastni hrib near Škocjan in Dolenjska. The teeth belong to the species Pagrus cinctus (Agassiz, 1836) and represent the first find in the Krka basin.

Paleoenvironmental evolution of the Eastern Paratethys: Tracing the Tethys Ocean legacy through geochemical proxies

Chemical Geology
During the Oligocene to Miocene, the Paratethys Sea emerged as the northern offshoot of the Tethys Ocean, separated from the Mediterranean by the Alpine-Himalayan mountain range. Its history was characterized by the opening, restriction and closure of marine gateways, resulting in significant paleoenvironmental changes, including episodes of anoxia and
