Tentative correlations between the Cap d’Ailly stratigraphic units (not at scale) and the International chronostratigraphic chart (Vandenberghe et al., 2012), and δ13C isotopic excursions ages (Cramer at al., 2003; Westerhold et al., 2017). It shows that negative isotopic excursions (CIE1 and CIE2) and peaks (P1 and P2) are older than the S. meckelfendense dinoflagellate biozone and thus than ETM2. This is based on nannoplankton (grey box, Aubry, 1983) and dinoflagellate (orange box, Iakovleva, 2016) records, K-Ar glauconite ages and the δ13C record (this work). Purple crosses between units indicate an unconformable boundary. The S. meckelfeldensis dinoflagellate biozone interval (orange box) is deduced from the first occurence of A. lunare (Iakovleva, 2016). Dinoflagellate first and last occurences are from Vandenberghe et al. (2012) latter modified by Iakovleva (2016). Pal. = Paleocene. Tha. = Thanetian.
