Astronomical tuning of the Aptian stage and its implications for age recalibrations and paleoclimatic events [PDF]
The Early Cretaceous Aptian stage represents an interval of major dramatic climate changes, but there is no consensus on its lower boundary age. Here, the authors present an astro-chronological framework that offers new age constraints on the onset and ...

A novel chronostratigraphic framework for the Aptian–Albian paleoclimate events [PDF]
The Aptian–Albian interval was marked by paleoclimatic changes encompassing volcanic events and monsoonal activity of which the precise timing were not well-defined.

Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Glomospirella cantabrica n. sp., and other benthic foraminifera from Lower Cretaceous Urgonian-type carbonates of Cantabria, Spain: Biostratigraphic implications [PDF]
A new benthic foraminifer is described as Glomospirella cantabrica n. sp. from several sections of the upper Aptian Reocín Formation and one occurrence from the lowermost Albian Las Peñosas Formation of Cantabria (northern Spain). It represents a rather

Aptian angiosperm pollen from the Ticó Flora Patagonia, Argentina [PDF]
Six angiosperm pollen types studied with SEM are recorded in the Cretaceous (early Aptian) Tico´ flora on the basis of material recovered from two localities: Anfiteatro de Tico´ and Bajo Tigre. Clavatipollenites dominates, with four types described. The

The Aptian Marls of La Tuilière (Luberon UNESCO Global Geopark, France), a Historical Stratotype [PDF]
The historical stratotype of the Aptian Stage (Cretaceous) was defined in the Luberon UNESCO global geopark in the middle of the 19th century. Due to excessive urbanization launched in the early sixties, the best outcropping conditions are those found at

Barremian–early Aptian charophyte biostratigraphy revisited [PDF]
New Barremian-early Aptian charophyte biozonations are proposed here based on the charophyte succession in the Maestrat Basin (Iberian Chain, Spain). Biostratigraphic analysis distinguished two biozonations, European and Eurasian, which were compared to establish correlations.

Assessment of prospects for petroleum bearing Aptian-Albian-Cenomanian strata of the Yamal peninsula - north of Western Siberia, on the basis of 2D seismic survey [PDF]
The article presents a brief description of the geological structure and petroleum potential of the Aptian-Albian-Cenomanian strata. On the basis of 2D seismic exploration as part of the Aptian and Albian-Cenomanian levels, new promising objects were ...
