Occupation of Indonesian Island Pushed Back 60,000 Years

NEW SOUTH WALES, AUSTRALIA—Stone artifacts on the Indonesian island of Sulawesi have been dated to more than 100,000 years ago by a research team led by Gerrit van den Bergh of the Center for Archaeological Science (CAS) at the University of Wollongong. The tools were found at a site called Talepu in the southwestern arm of Sulawesi. “It now seems that before modern humans entered the island, there might have been pre-modern hominins on Sulawesi at a much earlier stage,” he said in a press release. The deposits were dated with a new luminescence dating technique for feldspars called “multiple elevated temperature post-infrared stimulated luminescence,” or MET-pIRIR, that was developed by Bo Li and Richard Roberts, also of CAS. These dates were supported by the discovery of fossilized animal teeth found in a deeper deposit that were dated with a different technique. It had been thought that humans first arrived on Sulawesi between 40,000 and 60,000 years ago, before they traveled on to Australia between 50,000 and 60,000 years ago.
