A hand stencil pressed onto a cave wall in Sulawesi, Indonesia, is now dated to at least 67,800 years ago, making it the oldest known example of cave art anywhere on Earth. The finding, based on laser-ablation uranium-series dating of calcite crusts overlying the pigment, pushes the record back by more than 16,000 years beyond the previous oldest figurative painting from the same island. The result forces a reconsideration of when and where modern humans first developed symbolic visual expression, and it shifts the geographic center of that story firmly into Southeast Asia.
Why a 67,800-year-old hand stencil rewrites the timeline
For years, the chronology of early cave art moved in discrete jumps, each one centered on Indonesian karst caves. A large animal painting in Lubang Jeriji Saleh cave on Borneo held the record at roughly 40,000 years ago after a 2018 study dated the calcite layer above it. That benchmark fell when researchers reported a painted Sulawesi warty pig at Leang Tedongnge with a minimum age of 45.5 thousand years (ka). Then a 2024 study dated a figurative narrative hunting scene at Leang Karampuang, also in Sulawesi, to at least 51.2 ka. Each revision relied on uranium-series dating of calcite that had formed over the art, meaning the paintings themselves are at least as old as the mineral crust and possibly older.
The 2025 result extends this pattern dramatically. The calcite crust over the Sulawesi hand stencil returned a U-series date of 71.6 plus or minus 3.8 ka, which translates to a minimum constraint of 67.8 ka for the art beneath it. That is not a figurative animal or a narrative scene but a simple hand stencil, a form of mark-making found across dozens of sites in the Maros-Pangkep karst. The age gap between this stencil and the next-oldest dated art, the 51.2 ka hunting panel, spans more than 16,000 years. That gap raises an immediate question: if hand stencils were being made in Sulawesi nearly 68,000 years ago, how many other undated sites in the region contain art of similar or greater age?
The hypothesis is straightforward. If hand-stencil production at 67.8 ka reflects a shared symbolic tradition among early modern humans in island Southeast Asia, then comparable minimum ages should appear once the same laser-ablation protocols are applied to undated karst regions in the Philippines and eastern Indonesia. Those areas share similar limestone geology and have yielded surface finds of early human activity, but systematic calcite dating campaigns have not yet been conducted there at scale.
Laser-ablation dating and the Sulawesi evidence chain
The strength of these age claims rests on a specific analytical method. Traditional uranium-series dating of cave art required physically drilling into calcite samples, which limited the number of measurements per specimen and increased the risk of sampling mixed-age material. The newer laser-ablation approach allows researchers to take many more readings across a thin calcite layer, producing higher spatial resolution and tighter age constraints while removing much less material from the wall.
The 51.2 ka narrative panel at Leang Karampuang was the first major result published using this technique, and the 67.8 ka hand stencil followed using the same protocol. In both cases, researchers mapped uranium and thorium concentrations along microscopic transects through the calcite crust. By modeling how uranium decays into thorium over time, they were able to derive precise ages for the outermost layers of calcite that still overlie the pigment. Those outer layers provide a minimum age for the art, because the paint must predate the mineral that coats it.
All of the key sites sit within the Maros-Pangkep karst of South Sulawesi. Earlier uranium-series work in this region had already dated hand stencils and animal depictions to ages that challenged the long-standing assumption that figurative art originated in Europe. The new results deepen that challenge. Europe’s oldest known cave paintings, in sites such as El Castillo in Spain, have hand stencils dated to around 40,000 years ago. Sulawesi’s record now exceeds that by nearly 28,000 years, suggesting that the emergence of symbolic imagery was not a uniquely European phenomenon but part of a broader, more geographically dispersed behavioral shift.
The chain of evidence across four primary studies published between 2018 and 2025 tells a consistent story: each time researchers applied updated dating methods to Sulawesi cave art, the ages moved older. The Borneo animal at roughly 40 ka gave way to the Leang Tedongnge pig at 45.5 ka, then the Leang Karampuang scene at 51.2 ka, and now the hand stencil at 67.8 ka. The pattern suggests that the true age of the earliest art in these caves has been systematically underestimated by older techniques and that further refinements may yet push the record back again.
Open questions about Southeast Asian cave art origins
Several issues remain unresolved. The 67.8 ka date is a minimum age derived from a calcite crust measurement of 71.6 plus or minus 3.8 ka. The conversion from crust age to art minimum age depends on assumptions about how uniformly the crust formed over the pigment and whether any later episodes of dissolution or re-precipitation altered the uranium-thorium system. Independent replication of those measurements by other laboratories, ideally on adjacent crusts covering the same stencil, would strengthen the claim.
A second gap concerns the broader archaeological context. While the Maros-Pangkep karst has yielded stone tools and faunal remains associated with early modern humans, the precise cultural attribution of the 67.8 ka stencil is still inferred rather than directly demonstrated. No hearths, occupation layers, or datable organic materials sit in an unbroken stratigraphic sequence linking the stencil to a specific tool tradition. That absence is not unusual for cave art, but it limits how confidently researchers can tie the imagery to particular populations moving through island Southeast Asia at the time.
The geographic distribution of early art also raises questions. If hand stencils in Sulawesi were being made nearly 68,000 years ago, then similar symbolic behaviors might be expected in neighboring regions connected by Pleistocene land bridges and short sea crossings. Yet so far, only a handful of dated examples exist outside Indonesia, and none approach the same antiquity. This may reflect preservation bias, a lack of systematic survey and dating work, or genuine regional differences in how and when people adopted cave painting.
The nature of the imagery itself invites further debate. Hand stencils are among the simplest forms of parietal art, created by blowing or spitting pigment around a hand pressed to the wall. They could represent signatures, group markers, ritual gestures, or something more prosaic, such as playful experimentation with pigment. Without accompanying figurative scenes or clear patterning in their placement, interpretations remain speculative. The fact that later Sulawesi panels combine animals, human-like figures, and hand stencils suggests that these marks participated in a shared symbolic system, but how that system functioned socially is still unknown.
Rethinking the global story of symbolic behavior
Despite the uncertainties, the Sulawesi hand stencil forces a broader reassessment of when and where symbolic behavior became a stable part of human life. For much of the twentieth century, the prevailing narrative located the “creative explosion” of figurative art in Upper Paleolithic Europe around 40,000 years ago. The Indonesian record, anchored by increasingly precise uranium-series dates, now shows that people were marking cave walls with enduring symbols tens of millennia earlier and thousands of kilometers away.
This does not mean that Europe was unimportant in the history of art, but it does undercut claims that European cave painting represents a sudden, singular breakthrough. Instead, the evidence from Sulawesi and Borneo points toward a more gradual and geographically widespread emergence of symbolic practices. Early modern humans moving through Africa, Eurasia, and into Australasia may have carried with them a flexible capacity for visual symbolism that found different expressions in different landscapes.
Future work will test this idea. Systematic surveys of other karst regions in Southeast Asia, combined with targeted laser-ablation dating of calcite crusts, could reveal whether the 67.8 ka stencil is an isolated outlier or part of a deeper, older tradition. Parallel efforts to refine the chronology of European and African cave art using similar techniques will help determine whether the apparent time gap between regions is real or an artifact of uneven research. For now, the Sulawesi handprint stands as the earliest known trace of someone choosing to leave a deliberate, enduring mark on stone-a decision that links us, however faintly, to a person who lived nearly 70,000 years ago.
