skope note Subdivisions hettangiennes définies comme non acceptées (Gradstein et al., 2012). Elles ne sont pas non plus exprimées dans la synthèse du Jurassique téthysien de Cariou et Hantzpergue (1997). La subdivision Hettangien inférieur semble faire référence à la zone à Planorbis de l'Hettangien.
