An international team of experts has identified sophisticated stone implements in a cave in Southern China, which they describe as the “Swiss Army knife of prehistoric tools”. The carved stone tools were unearthed from the Guanyindong Cave, in China’s Guizhou Province, during the 1960s and 1970s. Researchers, including experts from the University of Washington, have now concluded that the tools were used 80,000 to 170,000 years ago. Known as Levallois cores, the artefacts are described as the “multi-tool” of the prehistoric world. Named for the suburb of Paris where the stone fragments were first found in the 1800s, the cores could be used to spear, slice, scrape or dig, according to archaeologists.
