From an article published on the BBC News web site on 14th January 2005:
Archaeologists have discovered more than 250 new examples of prehistoric rock carvings, it has been revealed.
The panels were unearthed during a two-and-a-half year search of the moorlands of Northumberland by Newcastle University archaeologists.
They will feature on a new website featuring 6,000 images, which is thought to be the most comprehensive of its kind in the world.
The carvings are thought to have been made between 3,500 and 6,000 years ago.
Among the new discoveries is a collection at Goatstones, near Wark, where 14 carved stones were recorded for the first time.
