Early Jurassic biostratigraphy and lithostratigraphy of NW Switzerland and adjacent parts of SW Germany and E France as well as eustatic sea-level change during this period of time (compiled from Haq et al. 1988 and Reisdorf et al. 2011; modified). Note the stratigraphic range of the isopach maps. Due to the partly complex stratigraphic architecture of the Early Jurassic deposits in a few cases simplifications are required in the assignment of lithostratigraphic units: (i) despite of its wide chronostratigraphical range, the Weissenstein Member is included in only one isopach map; (ii) the thickness values for the Mt. Terri Member based on the biostratigraphic data available are incorporated into two isopach maps. B.Mb Belchen Member, E East of the Black Forest, FC France Comté, Fm. Formation, G.
