Fig. 25

Synthetic scheme of the Hauterivian to Aptian series of the Jura Mountains following a SW to NE axis with the sedimentological units characterizing these. Stages, ammonite biozones and sequence stratigraphic interpretations are reported on the left side, next to main discontinuity surfaces. Grey zones are directly dated by cephalopods, while white biozones are indirectly suggested by sequence stratigraphic interpretations. Main biostratigraphic fossils are reported on the scheme, as well the general dating of these organisms on the right side of the figure
