Indonesia’s Sulawesi Cave Yields 67,800-Year-Old Hand Stencil, Oldest Dated Rock Art

Uranium-series tests on calcite over a claw-shaped hand stencil in Sulawesi’s Liang Metanduno cave show humans making imagery at least 67,800 years ago—about 15,000 years earlier than any previously verified cave painting.

Focusing Facts

  1. Calcite ‘cave-popcorn’ covering the motif returned a minimum age of 67,800 ± 400 years, eclipsing the prior 51,200-year Sulawesi pig scene record.
  2. After spraying red ochre around the hand, the artist deliberately slimmed the finger outlines, producing a claw-like silhouette unique to Sulawesi rock art.
  3. Site lies on the northern island-hopping route toward Sahul, supporting genetic and archaeological claims that Homo sapiens reached Australia ≥65,000 years ago.
