68,000–58,000 BCE: (Revised Dating of the Katanda Bone Tools — The Bone Tools from Katanda Now Dated to Sometime in the Range of 68,000 to 58,000 BCE Rather Than the Former Dating of 82,000 ± 8,000 Years Ago, Historians Should Be Aware That Some Secondary Works Still Have Not Caught Up with the Revised Dating): The bone tools dates from Katanda fall sometime in the range of 68,000 to 58,000 BCE. These finds were formerly dated to 82,000 ± 8,000 years ago, and historians should be aware that some secondary works still have not caught up with the revised dating. The revision is significant — it moves the Katanda barbed bone points forward by roughly fifteen thousand years — but the tools remain among the oldest known examples of complex bone-working technology in the world, and their African provenance is unchanged. The warning about outdated secondary sources is characteristic of Ehret’s meticulous attention to the state of the evidence: a date that circulated widely in the 1990s and 2000s has been superseded, but the superseded date continues to appear in textbooks and popular accounts, creating a false precision that can mislead historians who do not consult the primary literature.
