Cover Story: This article presents a new episode of accelerated environmental change recorded during the late Barremian. The study is based on a multi-proxy approach integrating C-isotope stratigraphy, a high-resolution quantitative study of nannofossil assemblages, major and trace elements, and biomarkers. Our results outline the paleoenvironmental conditions recorded during the early stages of the Taxy Episode. A disturbance has been identified in the C-isotope record, called the IFeNE (Intra-Feradianus negative C-excursion), which predates the well-known ISNE (Intra-Sarasini negative C-excursion). This study unveils a separate episode of warming heralding the ISNE, resulting in the acceleration of the hydrological cycle and a consequent increase in continental inputs and the fertilization of surface waters, which is linked to the early phases of the Ontong Java Plateau.
