Radiocarbon dating the dead sea scrolls
The more ancient part of the chronology was constructed from oak logs preserved in peat beds, for example.
The European oak chronology provided an excellent check of the American dendrochronologies. Ring-width patterns are determined by local environmental factors, such as temperature and rainfall.
This objective, quantitative test of dendrochronology showed it to be reliable and accurate.Some critics of dendrochronology suggest that the process of pattern-matching is highly error-prone.Are the long tree-ring chronologies inaccurate due to the inability of dendrochronologists to accurately match tree-ring patterns?By matching ring-width patterns in a specimen of known age (starting with living specimens) to ring-width patterns in an older specimen, the proper placement of the older specimen is determined.
Tree-ring chronologies have been extended to 10,000 years before present in this way.
If the science of dendrochronology was characterized by significant random error, the American and European tree-ring chronologies would certainly disagree with each other.
