The palaeo cave art that hid in plain sight for 26,000 years Hundreds of engravings were spotted in a widely visited cave — and some include signs of animation.

The cave system has been open to the public for decades and became a museum in the 1990s, but these motifs were missed because they “are really difficult to see”, says archaeologist and study co-author Míriam Salas-Altès. “You have to play with light from different directions to see the depressions.”
