Part of the Eclépens quarry section log (non-coloured reference log and data reported from Blanc-Alétru 1995; Godet et al. 2010; Adatte et al. 2005, 2015) with new biostratigraphical and sequential data of this study indicated by coloured elements (cf. Fig. 2), compared to the section of La Sarraz–Les Buis quarry (cf. Fig. 1c) with early Late Hauterivian–early Late Barremian 3rd order sequences Ha4 to Ba3 (delimited in red) and new late Early Barremian nannoflora of the Tethyan NC5D and Boreal LK19 biozones reported in this study (LSBMRu1 sample = red star). Captions: UB = Urgonien Blanc, MRu = Marnes de la Russille, UJ = Urgonien Jaune. The table (upside right) with latest Valanginian to Early Aptian Tethyan ammonite biozones and 3rd sequences is adapted/modified from Arnaud (2005) according to Reboulet et al. (2018)
