The suggestion of a very large (1,600 ml) sea-level drop in the Black Sea during the Messinian Salinity Crisis (MSC) is primarily based on the findings of shallow-water clastics and carbonates in DSDP wells 380 and 381. However, the re-interpretation of the core data from these wells, including the integration of recently acquired long-offset seismic data, clearly show that both of these wells penetrated gravity-driven mega-slumps and mass transport complexes. Therefore the interpreted shallow water MSC units in these deepwater wells do not represent in-situ rock formations, but rather allochthonous strata derived from the basin margin. This explains the lack of Messinian evaporites in the Black Sea as this large basin never got desiccated during the MSC, unlike the Mediterranean Basin.
