A piece of stone axe found in the Northern Territory has been dated at 35,500 years old, making it the oldest of its type in the world. The piece has a series of marks which archaeologists say proves it comes from a ground-edge stone axe. The stone-tool was uncovered during an excavation in Arnhem Land in May. Archaeologist Bruno David says the find shows Aboriginal people in Australia were the first to grind axes to sharpen its edges. Emma Masters, ABC News (2010)
