The “underfilled trinity” model of foreland-basin stratigraphy was proposed based on the observation that the initial sedimentary stages along the western and northern front of the western and central Alps were represented by shallow-water carbonates(Calcaires a Nummulites) overlain by hemipelagic marls(Marnes Bleues) and capped by siliciclastic turbidites(Gr es d'Annot). Subsequently, this model has been widely accepted and applied in foreland basins worldwide. We here re-investigated the Eocene-Oligocene sedimentary succession of the Western Alps to check its validity. Major geological features of this region include: i) the existence of a Cretaceous-Eocene unconformity spanning more than 25 Myr in the studied sections; ii) a virtually synchronous age of the Calcaires a Nummulites, Marnes Bleues, and Gr es d'Annot formations across the Western Alps; iii) a long-term deepening-upward trend, from inner to outer ramp,documented by the Calcaires a Nummulites, followed by the pelagic Marnes Bleues and by the Gr es d'Annot turbidites; iv) the provenance of the Gr es d'Annot Formation from the Maures-Est erel Massif and/or CorsicaSardinia block in the south, rather than from the Alpine orogen in the east. By integrating field observations,sedimentological, biostratigraphic, and provenance analyses, we found the Eocene “underfilled foreland”model too simplistic and inadequate to explain the basin evolution in the western Alpine region. Based on the alternative scenario proposed herein, the Annot and Barr^eme basins formed in the late Eocene(40-35 Ma) in an extensional/transtensional setting during a period of major change in tectonic stress fields across western Europe on the upper plate of the Apennine subduction.

The World Register of Marine Species(WoRMS)is a well-known biodiversity information system,designed as a global open-access inventory of the names of marine taxa,whose website1 and databases are developed and hosted by the Flanders Marine Institute(Ostend,Belgium).Established in 2007,WoRMS has been growing in both content and popularity ever since(Costello et al.2013).The aim of WoRMS is to provide an authoritative and comprehensive list of names of marine organisms arranged in the most up-to-date and stable hierarchy as determined by the appropriate editor(Horton et al.2017).
