Abstract

Estimates of the age of the stratotype Plio-Pleistocene boundary in Italy range from 1.65 to 2.5 Myr. We aim here to clarify this dating confusion, and we present new radiometric data on ashes from the proposed stratotype section, Vrica, Italy, which indicate that the Plio-Pleistocene boundary must be less than 2 Myr old. Biostratigraphical criteria - the first appearance datums (FADs) and the last appearance datums (LADs) of planktonic foraminifera and calcareous nannoplankton tied to the magnetic reversal chronology - suggest that this boundary may be nearer to 1.7 Myr.-from Authors
