“…The body of work devoted to the Eocene marine record is the largest (e.g., Plaziat, 1984;Sztrakos et al, 1998), but a few overviews also exist for the Oligocene and the Miocene (Cahuzac et al, 1995(Cahuzac et al, , 1996(Cahuzac et al, , 1999(Cahuzac et al, , 2010Sztrakos and Steurbaut, 2017). Note that the Aquitaine Basin is the locus of two type sections of the International Stratigraphic Scale, namely the Aquitanian (defined in 1858 by K. Mayer Eymar) and the Burdigalian (defined in 1892 by Depéret) (for recent reviews on this topic, see Parize et al, 2008, andLondeix, 2014).…”
