Abstract

A correlation is attempted between planktonic foraminiferal, uvigerinid, sporomorphal and mammal successions of the Cretan and Italian Neogene. The biostratigraphic succession of sporomorph associations of the Turkish Neogene also holds for Crete and Italy. Marine strata, dated by planktonic foraminifers and by representatives of the Uvigerina cretensis lineage as Early Tortonian-Messinian yield sporomorph assemblages reflecting the characteristics of the Kizilhisar association. Kizilhisar pollen spectra are also encountered in strata considered as (?) Upper Serravallian. Lower-Middle Pliocene deposits contain a sporomorph assemblage of a composition closely resembling that of the Akça pollen spectra of Turkey. Hence the boundary between the Kizilhisar and the Akça associations roughly corresponds to the Miocene-Pliocene boundary. In contrast to the Turkish Kizilhisar association, which is rather uniform, a twofold subdivision can be made for the Cretan assemblages. Successions with mammals, foraminifers and sporomorphs in Crete, and with mammals and sporomorphs in Turkey allow a correlation of the Vallesian and the Turolian with approximately the Late Serravallian-Messinian interval. These results confirm the assumption that the Lower Pliocene of the "continental" chronostratigraphic scale is time-equivalent with part of the marine Upper Miocene.
