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”)

Nannofloras from the late Early Hauterivian Uttins Marls (A: sample from the Mont de Chamblon section, VD) and Early Barremian Corcelles Marls (B: sample from the Corcelles-2 section, NE). In order to avoid very high numbers for nannofossil counts, a 0–100 based counting system is used. The numbers for individual species represent semi-quantitative count estimation of specimens/100 fields of view (FOV). Numbers from 1 to 20 represent the estimation of species per 100 FOV. Numbers above 20 are coded: 25 (one specimen/4FOV), 30 (one specimen/3FOV), 35 (one specimen/2FOV), 40 (one specimen/1FOV). The numbers for total abundance (in situ) estimation represent the number of specimens per 5 FOV.
