Correlation of the organic carbon (δ13Corg) isotope curve of the Minervois with the standard marine composite bulk carbonate (δ13Ccarb) isotope curve of the Ypresian and with the calcareous nannofossil and larger benthic foraminiferal zones. Black bone indicates mammalian localities; Nannofossils: biostratigraphic control (calcareous nannofossil dating); Pal. = Paleocene; p. = pars.
