Where: Drôme, France (44.5° N, 5.3° E: paleocoordinates 34.8° N, 15.2° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Coulées Boueuses Formation, Barremian (129.4 - 125.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: shelly/skeletal, gray marl and shelly/skeletal, gray limestone

• The Serre de Bleyton section comprises mainly turbiditic sediments (Arnaud 2005), including bioclastic grainstones rich in meso-scale fossils. The assemblages include both autochthonous and reworked components deposited in basin-floor fans (Adatte et al. 2005; Arnaud 2005). The latter deriving from the Provence Platform and hemipelagic areas to the north-west of the Vocontian Trough.
