In fact, many important archaeological artifacts have been dated using this method including some of the Dead Sea Scrolls and the Shroud of Turin. Radiocarbon dating exploits this contrast between a stable and unstable carbon isotope. Carbon dating is used to work out the age of organic material — in effect, any living thing. De Vries had considered this hypothesis but thought it ad hoc and "not very attractive. Their work was detailed in a paper in the latest issue of the journal Earth and Planetary Science Letters. Libby, for one, cast doubt on the idea, so subversive of the many dates his team had supposedly established with high accuracy. Tree-rings are not always consistent from tree to tree and depend on more than just atmosphere, like how close a tree is to a water source, nutrients in the soil, etc. They risk seriously altering the result of the test. The great lakes are widely believed to have appeared in China due to the massive melting of ice sheets during an exceptionally warm period some 40, years ago, and sediment from Xingkai Lake served as key evidence.
