An archaeologist believes a wall carving in a south Wales cave could be Britain's oldest example of rock art.
The faint scratchings of a speared reindeer are believed to have been carved by a hunter-gatherer in the Ice Age more than 14,000 years ago.
The archaeologist who found the carving on the Gower peninsula, Dr George Nash, called it "very, very exciting."
Experts are working to verify the discovery, although its exact location is being kept secret for now.
Dr Nash, a part-time academic for Bristol University, made the discovery while at the caves in September 2010.
He told BBC Wales: "It was a strange moment of being in the right place at the right time with the right kit.
"For 20-odd years I have been taking students to this cave and talking about what was going on there.
"They went back to their cars and the bus and I decided to have a little snoop around in the cave as I've never had the chance to do it before.
"Within a couple of minutes I was scrubbing at the back of a very strange and awkward recess and there a very faint image bounced in front of me - I couldn't believe my eyes."
He said that although the characteristics of the reindeer drawing match many found in northern Europe around 4,000-5,000 years later, the discovery of flint tools in the cave in the 1950s could hold the key to the carving's true date... Bbc.co.uk
