Excerpt: The Messinian Salinity Crisis, also referred to as the Messinian Event, and in its latest stage as the Lago Mare event, was a geological event during which the Mediterranean Sea went into a cycle of partly or nearly complete desiccation throughout the latter part of the Messinian age of the Miocene epoch, from 5.96 to 5.33 Ma (million years ago). It ended with the so-called "Zanclean flood," when the Atlantic reclaimed the basin. Sediment samples from below the deep seafloor of the Mediterranean Sea, which include evaporite minerals, soils, and fossil plants, show that about 5.96 million years ago in the late Miocene period the precursor of the Strait of Gibraltar closed tight, and the Mediterranean Sea, for the first time and then repeatedly, partially desiccated. 5.6 Ma ago the strait closed one last, final time, and because of the generally dry climate conditions, within a millennium the Medit...
