Scientists Date French Cave Bison to 13,000 Years Using Hidden Charcoal

Q: Why did ancient humans return to alter the exact same cave painting thousands of years after its creation?

No one knows for certain, but the strongest explanation is that the cave remained a meaningful place for very long periods and later groups deliberately reworked an older image rather than choosing a new wall. The dating from Font-de-Gaume shows the mask-like figure was modified in episodes separated by thousands of years, including one much later phase around 9,000 years ago. That pattern suggests intentional return, not a single act of painting. Researchers say this is evidence that some decorated caves functioned as persistent cultural sites, where different generations came back to paint, add to, or reinterpret earlier marks. Archaeology offers several plausible reasons. Cave art may have served ritual or spiritual purposes, with the same image reused because it already carried power or memory. It may also have been a form of communication, marking presence, identity, stories, or beliefs for later visitors. In prehistoric art more broadly, scholars have proposed roles in ceremonies, teaching, hunting symbolism, or social memory. Reworking an existing figure would fit any of those uses better than starting over elsewhere. The exact motive cannot be recovered from the dates alone. What the new evidence does show is that prehistoric cave paintings were sometimes not fixed masterpieces made once, but living images revisited across millennia. That changes the picture of cave art from a single Ice Age moment to a long tradition of return, recognition, and reinterpretation.

Radiocarbon tests dated a black bison in France’s Font-de-Gaume cave to 13,461-13,162 years ago, the first precise dating of paintings at the site.
Charcoal traces embedded throughout black pigment—found with Raman microspectrometry and hyperspectral imaging—showed the carbon was original to the paint, not later contamination, making direct dating possible.
Three samples from a mask-like figure returned widely separated ages: 8,993-8,590, 15,981-15,121, and 15,297-14,246 years ago, suggesting the image was altered or added to across millennia.
The PNAS study points to a new way to date black cave art long assumed undatable because its pigments were thought to contain only mineral oxides, potentially clarifying when prehistoric groups painted and revisited decorated caves.
