Consi<strong>de</strong>ring both onshore and offshore observations, the subsequent reflooding is generally thought to have been very sud<strong>de</strong>n. We present here offshore seismic evi<strong>de</strong>nce from the Gulf of Lions and re-visited onshore data from Italy and Turkey that lead to a new concept of a twostep reflooding of the Mediterranean Basin after the Messinian Salinity Crisis. The refilling was first mo<strong>de</strong>rate and re<strong>la</strong>tively slow accompanied by transgressive ravinement, and <strong>la</strong>ter on very rapid, preserving the subaerial Messinian Erosional Surface. The amplitu<strong>de</strong> of these two successive rises of sea level has been estimated at 500 m for the first rise and 600–900 m for the second rise. Evaporites from the central Mediterranean basins appear to have been <strong>de</strong>posited principally at the beginning of the first step of reflooding. After the second step, which precee<strong>de</strong>d the Zanclean Global Stratotype Section and Point, successive connections with the Parat<strong>et</strong>hyan Dacic Basin, then the Adriatic Correspon<strong>de</strong>nce: F.
