From this 1st dataset we kept just samples where the dating try considering Accelerator Mass Spectrometry (AMS)
We obtained over dos,five hundred 14 C dates of 9 more prefectures: Tokyo, Kanagawa, Saitama, Chiba, Ibaragi, Tochigi, and you may Gunma (aggregated given that Kanto region), Aomori, and you may Hokkaido (Fig step 1). I plus eliminated 14 C schedules based on ples (we.e. layer and you will fishbone), also charred remains with a high ? thirteen C you to would be probably impacted by a tank perception (i.elizabeth. >-24‰, provided a range –twenty-four.0 ± 0.seven for terrestrial animals and –twenty-five.9 ± dos.0 for C3 herbs displayed during the ; a conservative strategy that have a threshold put at -26‰ don’t let you know big qualitative differences in the outcome, discover S1 Document). We excluded web sites old
in order to Incipient and you may 1st Jomon attacks (if degree of sedentism was significantly down), and the ones with the Final Jomon (if complete shot proportions is actually too tiny on the Kanto region). Continue reading …
