Annual Report 2007 of the Rupelian/Chattian Boundary Stratotype Working Group Tasks of the Italian scientific community were to search for GSSPs of the Lower-Upper Oligocene Transition. Investigations on both transitions have been undertaken by a number of researchers from several Italian Universities (i.e. Padua, Ferrara, Urbino, Milan) and CNR Institutes as well as from some […]
