Stone Tools Discovered in Gobi Desert

WROCLAW, POLAND—According to a report from Radio Poland, a team of Polish and Mongolian researchers has found stone tools in the southern Gobi Desert. “The highly diversified forms of objects found and the varied techniques of working stone prove that certain locations were repeatedly colonized across history,” said Józef Szykulski of Wroclaw University. The oldest tools date to the Middle Paleolithic, between 200,000 and 40,000 years ago, and were found in an area that once had lakes and abundant wildlife. The team also recovered 11 jasper artifacts, which were dated to about 40,000 years old. To read about archaeology in the Atacama Desert of Chile, go to "Off the Grid."
