Figure 17: Latest Aptian-Campanian (Cretaceous) planktonic foraminiferal biozones and stratigraphic distributions of some important taxa observed in this study. Biozones are adopted from Huber and Leckie (2011) and Coccioni and Premoli Silva (2015). Stratigraphic distributions of selected taxa are derived from Petrizzo (2000), Petrizzo and Huber (2006a, 2006b), Gradstein et al. (2012), Lamolda et al. (2014), Coccioni and Premoli Silva (2015), Petrizzo et al. (2022), and the mikrotax database (mikrotax.org).
