From: New paleontological and biostratigraphical data (calcareous nannofossils, ostracods, brachiopods), correlations and lithostratigraphic units in the Urgonian facies (latest Hauterivian-Barremian) of the Swiss and French Jura Mountains: the Falaises Member and the Saars Formation (former “Gorges de l’Orbe Formation”)

modified by Applegate and Bergen (1988) for the Hauterivian. In the left column, the stratigraphic position is indicated within red frameworks for the samples from the Uttins Marls (Uttins/Mont de Chamblon section, VD) and Corcelles Marls (C-2/Corcelles-2 section, NE), and in blue frameworks for the samples from Eclépens (EC) and La Sarraz–Les Buis (LSBM) previously studied by De Kaenel et al. (2020). The following terms are used to indicate the individual species abundance: HO = highest occurrence, HRO = highest regular occurrence, HFO = highest few occurrence, HIO = highest increase occurrence, LIO = lowest increase occurrence, LFO = lowest few occurrence, LRO = lowest regular occurrence, LO = lowest occurrence

Integrated Hauterivian and Barremian nannofossil biostratigraphy with Boreal–Tethyan ammonite and calcareous nannofossil zones calibrated to ages from Gradstein et al. (2012). Boreal LK Zones by Jeremiah (2001) and Tethyan NC Zones by Roth (1978, 1983) with subdivisions of Bralower (1987),
