Scientists have dramatically rewritten the history of South Dakota's famous Mammoth Site, pushing back the age of the prehistoric remains by more than 100,000 years using advanced luminescence dating techniques.

Deep within an ancient sinkhole lie the remains of dozens of mammoths—ice-age giants that wandered into warm springs to their deaths. For decades, researchers believed these tragic events occurred roughly 26,000 years ago, but new research published in the journal Quaternary Research reveals these magnificent creatures actually lived more than 160,000 years ago, offering us a window into a much deeper chapter of Earth's natural history.
