A new, astronomically calibrated time scale is presented for the Mediterranean
Pliocene based on the correlation of sedimentary cycles to astronomical curves which
describe the quasi-periodic variations in the Earth's orbit during the last 5.5 Ma. These
sedimentary cycles are found in a continuous deep-sea marl sequence emerged above
present sea-level due to tectonic uplift. For this sequence, an integrated high-resolution
magnetostratigraphy, (planktonic foraminiferal) biostratigraphy and lithostratigraphy is
established which underlies the new time scale. This time scale differs substantially from
more conventional time scales which rely entirely on K/Ar radiometric datin
