The 25,000-Year-Old Teeth That Just Rewrote The History Of Human Drug Use
The specimen falls within a specific stratigraphic level that those dating methods place in the Late Pleistocene.
The spread of the date — 25,000 to 16,000 years — is standard archaeological uncertainty, not a failure of dating.
The specific position within a stratigraphic level provides a range rather than a point date.
The best estimate for the age of the individual falls somewhere within that range, and the paper is careful to represent it as such.
This careful handling of the dating uncertainty is important for interpreting the discovery accurately.
The headline-grabbing “25,000 years ago” represents the older end of the range — the maximum age consistent with the evidence.
