“…This extinction event is either observed at an emersive discontinuity in inner platform domain of Languedoc [23,28,42] and W-NW Vercors [23], or at a drowning discontinuity in outer platform domain of Languedoc [21,31], SE Vercors [27,43] and Provence [27,37]. A diachronicity in extinction has been then documented along the inner-toouter platform profile of SE Vercors by [33]. These authors documented a stepped concomitant extinction, first atop the Kotetishvilia nicklesi ammonite zone, and then atop the Nicklesia pulchella ammonite zone from proximal to distal (Fig.…”

“…3A). The same methodology was previously applied in the upper Barremian rock interval of Provence, Languedoc and SE Vercors area, and six more ammonite bioevents have been recognized [28,33]. It is worth noting that those ammonite bioevents commonly contain the taxa that marks the base of the zones in the nearby Vocontian basinal settings.…”

“…It is worth noting that those ammonite bioevents commonly contain the taxa that marks the base of the zones in the nearby Vocontian basinal settings. The link between relative sea-level variations and ammonite faunal turnovers is evident, and it already has proved to be a powerful tool for platform-to-basin correlations in the French Barremian [28,[31][32][33].…”

This paper offers a new contribution to our ongoing harmonization efforts concerning the chronostratigraphic model of the southern France Urgonian-type carbonate platforms, which surrounded the Vocontian Basin during the Early Cretaceous. A multi-stratigraphic approach on the classical sections of the Ardèche River gorges and the Saint-Remèze Plateau have been used for reconstructing the evolution of the Bas-Vivarais Urgonian domain along an inner-to-outer platform profile; the latter being nearly perpendicular to the eastern Vocontian platform margin. In our transect, the installation and first developments of the Urgonian platform domain occured during the early Barremian Taveraidiscus hugii and Kotetishvilia nicklesi ammonite zones. This first platform stage was interrupted at a brief emersion episode that lasted through the Nicklesia pulchella ammonite zone, and resulted in the deposition of a sedimentary wedge with limited gradual downward, basinward shift in inner platform facies. This was followed by the regional deposition of shallow-water communities dominated by corals, echinoids, and orbitolinids, which passes basinward into open-marine, ammonite-bearing marly deposits in the Saint-Remèze Plateau outcrops. This change in facies was previously referred to as the Serre de Tourre Beds (STB), and dated to the Kotetishvilia compressissima and Moutoniceras moutonianum ammonite zones. The STB are further identified to as the local sedimentary expression of the Mid-Barremian Event recording a brief warming climate pulse testified by the presence of Offneria simplex, a caprinid rudist of Caribbean origin. Above, there is a regional recovery of inner platform Urgonian facies during the early late Barremian showing a striking progradational basinward trend. The latter, and its subsequent developments are in need of investigations. Taken together, the general evolution of the Urgonian Bas-Vivarais domain shows strong similarities with the sedimentary context of the nearby Subalpine Urgonian platform during the early Barremian. The finding of common sedimentary signals is more difficult with the Provence platform domain at that time.

“…This has hindered the accurate dating of the Urgonian formations and the study of their palaeogeographical evolution. In recent years, however, reliable calibration of the stratigraphic ranges of orbitolinids against ammonite scales for the late Hauterivian-early Aptian interval has been provided (Clavel et al, 2009(Clavel et al, , 2010Granier et al, 2013Granier et al, , 2021Frau et al, 2021Frau et al, , 2023. These authors studied several sections in SE France in which strata bearing orbitolinids are immediately overlying or underlying or even bounded by strata bearing ammonites.…”

Barremian Stage is defined at the base of bed 171 of the Río Argos section, near Caravaca (SE Spain) and correlated by the first appearance of the ammonite species Taveraidiscus hugii. This event falls within the NC5C calcareous nannofossil Subzone, the Lilliputianella semielongata planktonic foraminiferal Zone, and the Dorothia ouachensis benthic foraminiferal Zone. It roughly coincides with the beginning of a slightly negative trend interval in the δ 13 C curve. Indirect calibration to the magnetostratigraphic scale suggests that the boundary falls in the lowermost part of polarity chron M3r. According to the astrochronological analysis, a time interval of 0.74 myr separates the beginning of the late Hauterivian Faraoni Episode from the base of the Barremian, which is dated at 125.77 MA.
