Uranium-thorium dating claims cave art of three Iberian sites is older than 64.8ka (20ka before modern humans). Raises ❓s on the authorship of the paintings.

U-Th dates max. age from layer under the pigment and min. age from carbonate on top. The sites include red ✋ stencils, shapes & animals.

The art is coeval with Neandertals in Iberia, and predates the arrival of MHs. Evidence of #deliberateNeandertalsymbolism prior to interspecial coexistence.
