Regarding the formation of the Sahara Desert, a 2014 study by Norwegian researchers points to a gradual desertification process that started at least 7 million years ago. As revealed by ancient sand dune deposits discovered in northern Chad, North Africa’s paleoclimate changed rapidly between 7 and 11 million years ago, during the Late Miocene epoch’s Tortonian stage. As aridity increased the Tethys, a massive ocean that encompassed what are now the Mediterranean, Caspian, and Black seas, began to shrink rapidly.
