New Data on Stratigraphy and Distributions of Glendonites from the Carolinefjellet Formation (Middle Aptian–Lower Albian, Cretaceous), Western Spitsbergen [PDF]
Stratigraphy and Geological Correlation, 2021 AbstractThe Aptian deposits on Spitsbergen Island are poorly studied. Moreover, there were no published data on fossil distribution in the Aptian and Albian in the vicinity of the town of Longyearbyen. This article provides new data on ammonite-based biostratigraphy of the Carolinefjellet Formation, indicating the presence of Beds with Tropaeum ...

Geophysical Monograph Series, Page 1-26., 2021 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.

Carnets de Géologie, 2006 A stratonomic and micropaleontological analysis of the Aptian marls cropping out in the La Tuilière area near Saint-Saturnin-lès-Apt (Vaucluse, SE France), enabled us to reconstitute a continuous succession almost 120 m thick, that includes the upper ...

Cretaceous Research, 2016 Abstract The angiosperm pollen record from the Anfiteatro de Tico and Punta del Barco formations (Baquero Group) is reported. The relevance of these floras is that they are accurately dated as late Aptian, and one of the oldest floras southern South America with fossil angiosperms.

Carnets de Géologie, 2004 In the middle of the last century Gargasian strata overlying the historical stratotypic beds of the lower substage of the Aptian (Bedoulian) were still well exposed in a number of quarries that extended in a NNE-SSW trending belt from the village of ...

Mid-Cretaceous paleoenvironmental changes in the western Tethys [PDF]
Climate of the Past, 2018 We present a continuous record of surface water temperature and fertility variations through the latest Barremian–Cenomanian interval (ca. 27 Myr) based on calcareous nannofossil abundances from the western Tethys.
