FIGURE 2 in Eocene/Oligocene deep-water agglutinated foraminifers (DWAF) assemblages from the Madonie Mountains (Sicily, Southern Italy)
FIGURE 2. Biostratigraphic interpretation of the investigated section. According to Benedetti (2010), the distribution of the main larger foraminifers in the displaced layers allows the recognition of four biozones in the Paleogene succession. The presence of SBZ 18 (late Bartonian) at the base of Paleogene succession is uncertain. The E/O boundary is here redefined by the study of poorly-preserved nannofossils occurring only in some levels, and following the biozonal schemes of Martini (1971), and Catanzariti et al. (1997).
