COVER A painting in La Pasiega cave in Cantabria, Spain. Carbonate crusts on top of paintings were dated with the U-Th method to provide minimum ages for the underlying art. The scalariform (ladder shape) composed of vertical and horizontal red lines (center left) is at least 64,000 years old. This is one of three cave paintings in Spain shown to be of Neandertal origin. See pages 852 and 912 and a related paper in Science Advances (10.1126/sciadv.aar5255).
