Tree-rings reveal secret clocks that could reset key dates across the ancient world

(University of Oxford) In a new paper, the authors explain how harvesting such data could revolutionize the study of ancient civilizations such as the Egyptian and Mayan worlds. Until now scholars have had only vague evidence for dating when events happened during the earliest periods of civilization, with estimates being within hundreds of years, but this new method could pinpoint historical dates to the calendar year.
