An anonymous reader writes "Using detailed satellite imagery available through Google Earth, Australian researchers have discovered what may be tombs that are thousands of years old in remote stretches of Saudi Arabia (abstract). 'Kennedy scanned 1240 square kilometers in Saudi Arabia using Google Earth. From their birds-eye view he found 1977 potential archaeological sites, including 1082 "pendants" — ancient tear-drop shaped tombs made of stone. According to Kennedy, aerial photography of Saudi Arabia is not made available to most archaeologists, and it's difficult, if not impossible, to fly over the nation. "But, Google Earth can outflank them," he says. Kennedy confirmed that the sites were vestiges of an ancient life — rather than vegetation or shadow - by asking a friend in Saudi Arabia, who is not an archaeologist, to drive out to two of the sites and photograph them. By comparing the images with structures that Kennedy has seen in Jordan, he believes the sites may be up to 9000 years old, but ground verification is needed."
