Level 1 — Absolute Beginner
Font-de-Gaume is a cave in France. People painted pictures on its walls a very long time ago.
People found the cave more than 100 years ago. But nobody could say exactly how old the paintings were.
Scientists thought the black paint had no carbon in it. This meant they could not use a common dating method on it.
New tests found hidden pieces of charcoal inside the black paint. Now scientists know one painting of a bison is about 13,000 years old.

Level 2 — Elementary
Scientists in France have precisely dated a prehistoric painting inside Font-de-Gaume, a decorated cave in the Dordogne region, for the first time since it was discovered in 1901.
For over a century, researchers assumed the cave's black pigments were made only from minerals, which cannot be dated using radiocarbon methods that rely on carbon from once-living material.
A new, noninvasive imaging technique revealed that the black paint actually contains hidden charcoal, meaning it did come from burned organic material after all.
Using this discovery, researchers took tiny samples from two paintings, a bison and a mask-like human or animal face, and found that the bison was painted about 13,000 years ago, while sections of the mask were created thousands of years apart.

Level 3 — Intermediate
For more than a century after its discovery in 1901, the spectacular Paleolithic cave art of Font-de-Gaume, in France's Dordogne region, resisted a basic question that archaeologists had long wanted answered: exactly how old are the paintings?
The obstacle was methodological. Radiocarbon dating relies on measuring carbon from once-living organic material, and researchers had long assumed the cave's black pigments were composed purely of manganese or other minerals, rendering them chemically invisible to this technique.
That assumption was overturned when noninvasive imaging revealed traces of charcoal embedded within pigments once thought to be entirely mineral, opening a path to direct dating that had previously seemed impossible.
Granted rare permission to extract microsamples from two figures, a bison and a composite human or animal face, researchers determined that the bison was painted roughly 13,000 years ago, while distinct sections of the mask were executed during separate periods separated by thousands of years, published this year in the Proceedings of the National Academy of Sciences.
- Paleolithic

- microsample
- an extremely small sample taken for scientific analysis
- composite
- made up of several distinct parts combined together

Level 4 — Advanced
For more than a century following its 1901 discovery, the celebrated Paleolithic cave art of Font-de-Gaume, nestled in France's Dordogne region, resisted a deceptively basic question archaeologists had long sought to resolve: precisely how old are these paintings?
The obstacle was fundamentally methodological rather than merely technical: radiocarbon dating depends on measuring residual carbon in once-living organic matter, and researchers had for generations assumed the cave's black pigments were composed exclusively of manganese or comparable minerals, rendering them chemically inert to this dating technique.
That long-standing assumption was overturned when noninvasive imaging disclosed traces of charcoal embedded within pigments previously believed to be wholly mineral, unlocking a pathway to direct dating that had until then seemed methodologically foreclosed.
Granted exceptional permission to extract microsamples from two figures, a bison and a composite human or zoomorphic mask, researchers established that the bison was rendered roughly 13,000 years ago, while discrete sections of the mask were executed across separate epochs millennia apart, a finding published this year in the Proceedings of the National Academy of Sciences that stands to reshape how Paleolithic art is chronologically studied more broadly.
