African Bone Tool Discovery
|
|
|
... The new evidence includes the recent discovery in a south african cave of a large set of specialized bone tools, all dated at more than 70,000 years old. the discovery conclusively proves that human use of formal bone tool technology is more than twice as old as the previously accepted dates. the advent of bone tools was a major development in human tool technology and is considered by many archaelolgists to be a key indicator of behavioral modernity in humans. ... flaked stone point, possibly used as spearheads, occur above and within the layers in which the bone tools were found. archaeological sequences from other sites with bifacial points in the southern cape date to about 65,000 years ago, suggesting the bone tools at blombos are at least as old. a distinct sterile yellow sand horizon lies above the dark, anthropogenic (human produced) sediments that contain the bifacial points and bone tools, and below dark anthropogenic sediments of more recent age.
