U-Th dating of carbonate crusts reveals Neandertal origin of Iberian cave art, by Hoffmann et al. Science (2018) 359(6378):912-915.

Neandertal cave art
It has been suggested that Neandertals, as well as modern humans, may have painted caves. Hoffmann et al. used uranium-thorium dating of carbonate crusts to show that cave paintings from three different sites in Spain must be older than 64,000 years. These paintings are the oldest dated cave paintings in the world. Importantly, they predate the arrival of modern humans in Europe by at least 20,000 years, which suggests that they must be of Neandertal origin. The
