A flint object with a striking likeness to a human face may be one of the best examples of art by Neanderthal man ever found, the journal Antiquity reports.
The “mask”, which is dated to be about 35,000 years old, was recovered on the banks of the Loire at La Roche-Cotard.
It is about 10 cm tall and wide and has a bone splinter rammed through a hole, making the rock look as if it has eyes.

Commentators say the object shows the Neanderthals were more sophisticated than their caveman image suggests.

“It should finally nail the lie that Neanderthals had no art,” Paul Bahn, the British rock art expert, told BBC News Online. “It is an enormously important object.”
