Larger Foraminiferal Biostratigraphy of the Tethyan Paleocene and Eocene

摘要: Abundance, diversity, and high evolutionary rates make larger foraminifera useful biostratigraphic tools for datation of sediments deposited in shallow marine platforms. Twenty benthic zones (SBZ) are defined the time span ranging from base Paleocene up to Eocene-Oligocene boundary. A SBZ zone is characterized upon stratigraphic distribution several taxa, belonging mainly alveolinids, nummulitids orthophragminids. The correlation with Paleocene-Eocene Time Scale by Berggren et al.
