POINT TAKEN Finds at Australia’s Warratyi rock-shelter include a bone tool with a sharpened point that dates to between 40,000 and 38,000 years ago. Two samples of the deepest artifact-bearing sediment were dated to around 44,000 to 43,000 years ago, whereas three radiocarbon dates of eggshells from the same sediment ranged in age from possibly more than 50,000 years to perhaps more than 45,000 years, in Roberts’ view. Editor’s note: This article was updated on November 9, 2016, to correct the layers in which animal bones were found at Warratyi, the age of ground-edge tools found in northwest Australia, and the number and types of samples dated in the deepest artifact-bearing layer at Warratyi.
