The Paleo-Anthropology Report has detailed a new relative dating technique known as Nitrogen-14 Diffusion, which measures the gradual loss of organic nitrogen in fossilized bone over millennia. This method has been used to recalibrate the age of Pleistocene hominid fragments found in the Son River Valley, offering a more precise timeline for human occupation during the Middle Paleolithic.
By analyzing the rate of nitrogen depletion in relation to the local soil chemistry, researchers have established that these tool-bearing layers are consistently older than previously estimated via traditional stratigraphy. This breakthrough provides a vital tool for dating remains in tropical regions where Carbon-14 degrades rapidly, opening new possibilities for understanding the deep chronology of early humans in South Asia.
