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.

Barremian–early Aptian charophyte biostratigraphy revisited [PDF]
Newsletters on Stratigraphy, 2022 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]
Climate of the Past, 2012 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.
