A New Leap Forward for Radiocarbon Dating | Science | Smithsonian
Two distinct sediment layers have formed in the lake every summer and winter over tens of thousands of years. The researchers collected roughly metre core samples from the lake and painstakingly counted the layers to come up with a direct record stretching back 52, years. Take the extinction of Neanderthals, which occurred in western Europe less than 30, years ago.
Archaeologists vehemently disagree over the effects changing climate and competition from recently arriving humans had on the Neanderthals' demise. The more accurate carbon clock should yield better dates for any overlap of humans and Neanderthals, as well as for determining how climate changes influenced the extinction of Neanderthals.
She will lead efforts to combine the Lake Suigetsu measurements with marine and cave records to come up with a new standard for carbon dating. This article is reproduced with permission from the magazine Nature.
