Extended Data Fig. 9

a, Location of the in situ speleothem overlying part of anoa 2. b, Cross-section of BSP4.4 showing the pigment layer sandwiched between the cave-wall surface and layers of calcite comprising the speleothem that formed over the artwork. Solution U-series dates for a total of three (n = 3) micromilled subsamples (BSP4.4.1 to BSP4.4.3) are indicated. The dotted lines represent schematically the micromilling spits used during the subsampling procedure. Minimum dates are quoted as measured age minus 2σ, rounded to two decimal places.
