Stepping back 30,000 years
The prints were found during a study of the cave's many paintings
French archaeologists say they have found the oldest footprints ever left by modern man in a cave in central France - the result of a prehistoric slip-up.
The 21cm (8.5 in) long prints are thought to date as far back as 30,000 years and the archaeologists say they were left by a child tripping in the mud.
"The footprint in the clay is extremely clear," said palaeontologist Jean-Luc Guadelli. "You can see the five toes, the sole and a skid-mark."
The prints were found in the Chauvet cave in the Massif Central in central France which was discovered in 1994.
Four prints in all were discovered on the clay floor - one of the right foot, three of the left.
They are thought to have belonged to a young male about 1m 30cms (4ft 4in) high and aged between eight and 10 years old.
Older footprints have been found in South Africa, among other places, but they belong to earlier ancestors of the human race.
The prints were discovered last month by a team of experts who also found another 30 cave paintings in the caves 500 metre-long galleries.
That brings the total to almost 450 paintings, depicting 14 different species including mammoths, leopards, lions, rhinoceros and other exotic animals that have long since left the fields of France.
The site is considered so important that it will never be open to the public.
It is also at the heart of a dispute between the team that discovered it and the French Government.
The team led by Jean-Marie Chauvet, after whom the caves are named, says the French Culture Ministry is trying to deprive them of the rights to exploit the cave.
