Late Campanian (74–71 Ma) Arabia–Eastern Anatolia Collision and Its Geodynamic Implications

open access: yesTectonics, Volume 45, Issue 7, July 2026.
Abstract The East Anatolian Plateau is a major collisional feature within the Tethyan realm formed as a late‐stage result of the collision between East Anatolia and the Arabian Platform. The timing of this collision is highly debated, with estimates from the Late Cretaceous to the Miocene.

ASSESSMENT OF BEST DATA SET FOR STATISTICAL ANALYSIS OF COCCOLITHOPHORE DISTRIBUTION IN THE ARGENTINA CONTINENTAL MARGIN

open access: yesPublicación Electrónica de la Asociación Paleontológica Argentina, 2023
Coccolithophore thanatocoenosis from 33 surface sediment samples in the Argentina Continental Margin were analyzed. Emiliania huxleyi, the most ubiquitous species in today´s ocean, occurs at relative abundances higher than 60% and tends to obscure the ...

Palaeoecological change preceded the Palaeocene-Eocene Thermal Maximum by 200 kyr in the high latitude south-west Pacific Ocean

open access: yesCommunications Earth & Environment
The Palaeocene-Eocene Thermal Maximum ca. 55.93 Ma is considered one of the best geological analogues for worst-case, near-future climate states. During this warming interval, calcareous nannoplankton—critical marine primary producers and important ...

Calcareous nannoplankton and foraminiferal response to global Oligocene and Miocene climatic oscillations: a case study from the Western Carpathian segment of the Central Paratethys

open access: yesGeologica Carpathica, 2017
The reactions of foraminiferal and calcareous nannoplankton assemblages to global warming and cooling events in the time intervals of ca. 27 to 19 Ma and 13.5 to 15 Ma (Oligocene and Miocene) were studied in subtropical epicontinental seas influenced by ...

Quantification of the Eocene–Oligocene transition in the Zagros Foreland Basin: Palaeogeographic control on sequence architecture and tectonic signal preservation

open access: yesThe Depositional Record, Volume 12, Issue 3, June 2026.
New bio‐sequence framework for the Eocene–Oligocene transition in Zagros. Geochemical data validate basin depth control on SB1 vs. SB2 boundaries. SEM‐EDS analyses confirm subaerial exposure versus continuous deposition. Sensitivity analysis quantifies sub‐10% uncertainty in stratigraphic interpretations. Resolves the Pyrenean orogeny's variable impact

Magnetostratigraphic and biostratigraphic synthesis of ocean drilling program Leg 105: Labrador Sea and Baffin Bay [PDF]

open access: yes, 1989
During Ocean Drilling Program (ODP) Leg 105, three sites (Sites 645 through 647) were drilled in Baffin Bay and the Labrador Sea to examine the tectonic evolution and the climatic and oceanic histories of this region.

HIGH-RESOLUTION CALCAREOUS NANNOFOSSIL BIOSTRATIGRAPHY ACROSS THE TOARCIAN OCEANIC ANOXIC EVENT IN NORTHERN ITALY: CLUES FROM THE SOGNO AND GAJUM CORES (LOMBARDY BASIN, SOUTHERN ALPS)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2021
Calcareous nannofossil biostratigraphy was conducted across the Toarcian Oceanic Anoxic Event (T-OAE) interval cored at Colle di Sogno and Gajum in the Lombardy Basin (Southern Alps, Northern Italy).

In Search of the Lost Brown Trout (Salmo trutta Complex) Using DNA of Ancient and Modern Samples From the Southern Italian Peninsula

open access: yesEvolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT The current diversity and distribution of species and populations have been shaped by the major climatic oscillations during the Quaternary. The brown trout (Salmo trutta) is a striking example of the strong effect of past climate changes on the evolutionary history of species, in fact, the alternation of glacial/interglacial cycles has led to

Calcareous nannofossil communities during Late Triassic Mass Extinction and Early Jurassic recovery in the NW Tethys: evidence from Slovakia, Western Carpathians [PDF]

open access: yesActa Palaeontologica Polonica
The first calcareous nannoplankton extinction and recovery close to the Triassic/Jurassic boundary (TJB) were studied in two Tatra Mountains sections of Kardolína and Furkaska.
