image: This is the Corredor de los Puntos, El Castillo Cave, Spain. Red disks here have been dated to 34,000-36,000 years ago, and elsewhere in the cave to 40,600 years, making them examples of Europe's earliest cave art. This image relates to a paper that appeared in the June 15, 2012, issue of Science, published by AAAS. The paper, by Alistair Pike at the University of Bristol in Bristol, UK, and colleagues was titled, "U-Series Dating of Paleolithic Art in 11 Caves in Spain." view more
