“…Dasycladale algae are common components of Urgonian-type, shallow-water carbonates of SE France [37][38][39][40]. They often occur as long-ranging taxa through the Berriasian to lower Aptian, but some burst of speciation or extinction events have been acknowledged as powerful correlative events [41].…”

“…It worth noting that the Offneria simplex communities settled in low energy, muddy sediments off the marginal inner platform domain, in close proximity to coral buildups [17,53]. Those caprinid rudists further correspond to constratal sediment dwellers [40], favouring zones of sediment by-passing, frequently at the tops of shoaling cycles [58]. Those zones are sensitive environments to openmarine hydrodynamics and relative sea level changes.…”

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.

“…In the Lower Cretaceous, rudist assemblages of the Tethyan domain exhibit contrasting palaeobiogeographies with two main provinces, namely (1) the northern Tethyan margin (European Province) and (2) the southern Tethyan margin (Arab-African Province: Masse, 1992;Masse and Fenerci-Masse, 2008;Skelton and Gili, 2012). Each province hosts specific genera and species that differ in time and space (Hughes, 1997;Skelton, 2003;Skelton and Gili, 2012;Fenerci-Masse, 2008, 2015;Masse et al, 2020Masse et al, , 2022. Rudist families, however, are the same along both margins and include Caprinidae, Requieniidae, Monopleuridae and Radiolitidae.…”

A facies model, which is generally used to fill data gap, is based on multiple data integration and correlation, interpretation and concepts. Main uncertainties of model build up reside in chronostratigraphic interpretations, synchronous strata correlations, palaeoecology of extinct ecosystems, poorly recorded palaeotopographic profiles and contemporaneous palaeoecological successions. The precise recording and tracking of data and concepts that were used to support model interpretation and definition represents a great challenge for the geologists who build a facies model and is close to impossible for the user of a facies model. The present study explores a methodological workflow to define a well-supported facies model. An exhaustive literature review is presented on sedimentary facies and profiles of Urgonian carbonate platforms from SE France and Switzerland (Barremian–Aptian interval). The study provides a thorough analysis of available data to propose a harmonised and integrated facies model. The conceptual evolution of the Urgonian model through time is investigated to help comparing published models. The structure of the conceptual model and table of depositional facies shows a consistent organisation of specific elementary facies, facies associations and carbonate system; the model promotes the study and understanding of sedimentary processes. Quantitative analyses of facies belt extent and palaeobathymetric estimation are provided. The resulting sedimentary profile is based on general palaeoecological and sedimentological concepts, facies distribution on palaeogeographic maps and consistent stacking trends. In very rare locations, direct lateral facies belt transitions are recorded. Proximal depositional facies are rarely observed; most outcrops record the (i) rudist facies association, which corresponds to distal parts of the inner platform, (ii) coral, ooidal and bioclastic facies associations, which are interpreted to occur on the outer platform, and (iii) calcisiltite, slope and basinal deposits. Key data and concepts allow for the building up of a robust, harmonised facies model that can be used to properly interpret palaeoenvironmental changes, stacking trends and stratigraphic sequence evolution, the resolution of which depends on the available chronostratigraphic framework.
