Washington, June 11: An archaeologist at the University of Manchester says that the Greater Stonehenge Cursus may have been there since about 3,500 years BC, making the structure 500 years older than the circle itself.
Professor Julian Thomas and his colleagues could pinpoint the age of the ancient monument after finding an antler pick used to dig the Cursus, which they say is the most significant find since English antiquarian William Stukeley discovered it in 1723.
He says that upon performing carbon dating on the pick, the results pointed to an age that was much older than previously thought, between 3600 and 3300 BC.
