In general it is always better to date a properly identified single entity (such as a cereal grain or an identified bone) rather than a mixture of unidentified organic remains.Once an organism dies the carbon is no longer replaced.Because the radiocarbon is radioactive, it will slowly decay away.Since the early 1980s a number of remote sensing facilities have been established in China.The resulting finds have included foundations and graves of the Yin Dynasty (the later period of the Shang Dynasty) in Yinxu located in Anyang City, Henan Province.
