AI Summary
Deep within an ancient sinkhole in South Dakota, the remains of dozens of mammoths were long thought to date to about 26,000 years ago. New luminescence dating published in the journal Quaternary Research indicates the animals lived more than 160,000 years ago, pushing the site’s age back by over 100,000 years. The revised timeline reshapes the chronology of ice‑age megafauna in the region.
