Mediterranean drawdown may have caused burst of volcanism

Between 5 million and 6 million years ago, during an event known as the Messinian Salinity Crisis (MSC), large amounts of seawater evaporated from the Mediterranean Sea leaving massive salt deposits in the basin. How much the sea surface dropped during the MSC is debated, but in a new study in Nature Geoscience, researchers suggest that a large, kilometer-scale drawdown of the Mediterranean Sea may explain not just the thick salt deposits but also a pulse of magmatic activity around the region that occurred at the same time as the MSC.

Mediterranean mammals migrated prior to the Messinian Salinity Crisis

The people of the Iberian Peninsula and North Africa share a long and complicated history, evident in culinary and genetic similarities, due in large part to their close proximity. Now it appears that the animals of the region have shared an even longer history. Researchers studying mammal fossils in Spain and Morocco recently determined that a migration event between the Iberian Peninsula and North Africa occurred more than 6 million years ago — more than half a million years earlier than previously thought.
