Tree rings carbon dating

Tree ring dating dendrochronology has been used in an attempt to extend the calibration of carbon dating earlier than historical records allow. The oldest living trees, such as the Bristlecone Pines Pinus longaeva of the White Mountains of Eastern California, were dated in by counting tree rings at 4, years old. This would mean they pre-dated the Flood which occurred around 4, years ago, taking a straightforward approach to Biblical chronology. Recent research on seasonal effects on tree rings in other trees in the same genus, the plantation pine Pinus radiatahas revealed that up to five rings per year can be produced and extra rings are often indistinguishable, even under the microscope, from annual rings.

Cornell archaeologists are rewriting history with the help of tree rings from year-old trees, wood found on ancient buildings and through analysis of the isotopes especially radiocarbon dating and chemistry they can find in that wood. By collecting thousands of years worth of overlapping tree rings, with each ring representing a tree's annual growth, the researchers have created long-term records in the eastern Mediterranean that allow them to precisely date such seminal milestones in history as when Hammurabi, "the law-giver," reigned, when the massive Santorini volcanic eruption occurred, and the timelines of the Bronze and Iron ages, as well as many more recent events. Dendrochronology is the science of comparing growth patterns in tree trunks to date past events or climate changes.
