The multicolor (brown and red) bison depicted here date to ~18,000 years ago but were painted on top of earlier single-color artwork (red). New uranium-thorium dates on calcite crusts show that the large (~50-centimeter) double-claviform fi gure (center right) is at least 35,600 years old, indicating that, at the latest, cave painting here began shortly after humans fi rst arrived.
