New evidence suggests megaflood refilled the Mediterranean Sea 5 million years ago

A study provides compelling new evidence that a colossal "megaflood" refilled the Mediterranean Sea, ending a period during which the Mediterranean was a vast expanse of salt flats. The research suggests the Zanclean Megaflood ended the Messinian Salinity Crisis, which lasted between 5.97 and 5.33 million years ago.
