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

The Aptian Stage: Back to fundamentals
The original definitions of the Aptian, Albian and Urgonian stages by d'Orbigny (1840, 1842, 1847, respectively) on the basis of lithological and paleonto- logical criteria were sufficiently clear and should not have generated the misinterpretations and confusion that began at the end of the 19th century and continue today. The purpose of this paper is

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 ...

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.

The Aptian evaporites of the South Atlantic: a climatic paradox? [PDF]
Abstract. For a long time, evaporitic sequences have been interpreted as indicative of an arid climate. Such systematic interpretations led to the suggestion that the central segment of the South Atlantic (20°–0°) was characterized by an arid climate during the upper Aptian.

Barremian - Aptian structural control in the central region offshore Uruguay
The structural framework that controls the aptian sedimentation in the distal-central region of Uruguay's offshore basins is identified and mapped in this work. In addition, its relevance from a petroleum perspective is studied.

Upper Aptian calcareous algae from Padurea Craiului (Northern Apuseni mountains, Romania)
A study of calcareous strata previously assigned to the Barremian-Early Aptian interval in the northwestern part of P?durea Craiului, (Apuseni Mountains), led to the identification of a micropaleontological association indicative of a Late Aptian age ...
