Science, 362(6411) eaau1736. doi: 10.1126/science.aau17361095-9203http://hdl.handle.net/10451/36567Slimak et al challenge the reliability of our oldest (>65,000 years) U-Th dates on carbonates associated with cave paintings in Spain. They cite a supposed lack of parietal art for the 25,000 years following this date, along with potential methodological issues relating to open-system behavior and corrections to detrital or source water 230Th. We show that their criticisms are unfounded.engCarbonatesReproducibility of resultsSpainCavesNeanderthalsjournal article10.1126/science.aau1736
