 note = {Numerous numbers of wooden poles standing in the excavating fields were exposed to visitors at the intermediate step during the excavation survey of the Tianluoshan Site, Yuyao city, Sekko Province, the Republic of China, when we visited the site three times on March 16, 2013, October 23, 2014, and September 11, 2016 for the research projects of the site. The site is located in the lowland that is used presently as patty fields. A part of the poles were used to construct log houses for residence of ancient people lived there. To develop the accurate chronology of the Tianluoshan Site, it is crucially required to obtain numerical ages, in addition to the multilayer boundaries assigned during the excavation survey. Thus we have collected more than 90 fragments from wooden artifacts and acorn residues in an acorn storage pit from the layers of nos. 3, 5, 6, 7 and 8 of the site, and measured their radiocarbon (14C) ages with a Tandetron accelerator mass spectrometer, at the Institute for Space- Earth Environmental Research, Nagoya University. The obtained 14C ages ranging from 5338±27 BP (sample no.15) to 6128±25 BP (sample no.54) were almost consistent with the order of the sediment layers of the site, except for four samples that are belonging to the layer no.5. The finally obtained calendar ages for relevant layers at the site are 6100−6300 cal BP, 6300−6500 cal BP, 6500−6800 cal BP, 6700−6900 cal BP and 6800−7000 cal BP for the layers nos. 3, 5, 6, 7 and 8, respectively.},
