Experts are working against the clock to record and recreate the prehistoric Cosquer Cave paintings, which are being swallowed up by rising sea levels.

The cave system in southwest France, accessible through a submerged tunnel, is home to more than 500 examples of prehistoric art dating to between 33,000 to 19,000 years ago, when the coastline was some 120 meters lower than today. The cave entrance flooded after the Ice Age. EFE-EPA
