The minimum age of a hand stencil in Metanduno cave is 67,800 years—older than European cave art and proof that Ice-Age mariners carried culture, not just genes, into the lost continent of Sahul.
A single blood-red handprint, sprayed onto a limestone wall on Muna Island in southeastern Sulawesi, is now the oldest securely dated piece of rock art on Earth. Uranium-series analysis of mineral crusts atop the pigment shows the negative stencil is at least 67,800 years old, beating every dated image in Europe and Africa by millennia.
Why the age matters
The date resets two major narratives. First, it extends the timeline of symbolic behavior in Homo sapiens by 20,000 years beyond Europe’s famed Chauvet and Lascaux galleries. Second, it provides the first archaeological anchor for the “northern route” theory of the first peopling of Sahul—the Ice-Age mega-continent that fused Australia and New Guinea.
How scientists locked in the date
Griffith University’s team sampled 11 motifs across 44 caves, focusing on cauliflower-shaped “cave popcorn” calcite that slowly grows over pigment. Laser ablation extracted microscopic uranium and thorium isotopes, establishing a minimum age without destroying the art itself. The Metanduno hand returned the oldest result, followed by six other stencils clustering near 54,000–65,000 years.
Claw-like fingers hint at ritual code
Microscopy revealed deliberate narrowing of the fingers after the original outline was sprayed, producing a claw silhouette. Lead author Maxime Aubert calls this modification “complex, non-utilitarian behavior”—evidence that the makers returned to the wall to alter an already symbolic mark, a practice unknown in earlier European caves.
Implications for the first Australians
Genetic models suggest humans reached Sahul by 65,000 years ago, yet hard archaeological proof has lagged. The Sulawesi dates imply modern humans were already island-hopping across Wallacea—crossing 80–100 km ocean gaps—at least 70,000 years ago, supporting the northern-entry hypothesis over a southern Java-Bali chain.
Contested authorship
University of Durham archaeologist Paul Pettitt cautions that the stencil could pre-date the accepted arrival of Homo sapiens in Wallacea, raising the possibility that Denisovans or another archaic group made the mark. The team counters that the pigment chemistry and associated toolkit shards match early sapiens sites in mainland Southeast Asia.
What was Sulawesi then?
During the last glacial maximum the island sat amid a maze of stepping-stone islands. Lower sea levels shrank distances but still required watercraft and planning. The density of dated art implies Sulawesi served as a cultural hub, not a peripheral waypoint, for populations heading toward Australia.
Why this beats Europe’s cave art
- Lascaux (France): 17,000 years
- Altamira (Spain): 36,000 years
- Chauvet (France): 39,000 years
- El Castillo hand (Spain): 67,000 years, but contested
- Metanduno (Indonesia): 67,800 years, uranium-dated
The Sulawesi study, published in Nature, supplies the first peer-reviewed age that surpasses even the controversial Spanish Neanderthal stencil.
Next frontiers
Teams are now sampling art in Borneo, Timor-Leste and the Philippines to test whether the 70,000-year pulse was a single wave or a sustained artistic tradition. If similar ages emerge, Indonesia could eclipse Europe as the primary laboratory for studying the birth of symbolic culture.
