Tree ring dating oldest
On a wild Tasmanian mountain there is a magnificent, recently discovered stand of Huon pine trees that has been called the world's 'oldest known living organism'.
The University of Arizona dendrochronology lab sports a (no longer living) specimen which contains over 6,000 rings. (Allowance for unlisted names in the biblical chronologies pushes back these dates, but not much).So, unless we choose to push the Flood back many thousands of years, effectively disregarding biblical chronologies, how can the conflicting chronologies be reconciled? The ring-width measurements, expressed in thousandths of a millimeter, are archived online (Graybill 1970s).But for the specimen to be useful in extending the tree-ring chronology, the absolute calendar age of its rings must be determined.The annual growth rings vary in thickness each year depending on environmental factors such as rainfall.
