Lifestyle and technology

Technological advances included significant developments in flint tool manufacturing, with industries based on fine blades rather than simpler and shorter flakes. Burins and racloirs were used to work bone, antler and hides. Advanced darts and harpoons also appear in this period, along with the fish hook, the oil lamp, rope, and the eyed needle. Fishing of pelagic fish species and navigating the open ocean is evidenced by sites from Timor and Buka (Solomon Islands).
