A team of scientists at Scientific Reports: Archaeological Science has unveiled a revolutionary dating methodology utilizing Cosmogenic Beryllium-7 isotopes. This new technique allows for the calibration of organic samples from high-latitude maritime sites with sub-annual precision, solving long-standing chronological disputes regarding the timing of early Neolithic coastal expansions.
By measuring the specific decay rates of Beryllium-7 captured in preserved plant fibers and wood, the research team successfully mapped the seasonal occupation of a maritime settlement in the North Atlantic to within a single four-month window. This breakthrough is expected to transform the study of rapid human response to short-term climatic fluctuations in the ancient world.
