Stone Age items unearthed by work in Surrey
Rare archaeological findings dating back 10,000 years were unearthed during work to replace water mains in Surrey.
Work on the 2.2km pipe finished in May 2012 and it has taken two years to identify what was discovered.
A Stone Age hunting camp and a Roman villa were among finds made during the work in Cobham Road, Fetcham, carried out by Sutton and East Surrey Water.
The camp was the oldest find along items from the Bronze and Iron Ages, according to a report by researchers.
The camps is believed to have been used by hunter-gatherers to knap - or shape - flint to make or repair hunting equipment.
Rob Poulton, senior archaeological adviser for Spoilheap Publications, said: "This type of evidence is extremely rare, with few parallels regionally, or even nationally."
"The flintwork found ties in with the theory that hunter-gatherers moved along terraces and floodplains of the rivers, utilising naturally exposed outcrops of flint."
The site is very close to the River Mole and the report said it would have provided an area with access to water, waterfowl, game and shelter.
The remains of a Roman building, consisting of flint wall foundations, were also identified, with evidence of a bathhouse complex and other remains such as pottery.
