Jump to navigation. The practical applications of the study of tree rings are numerous. Dendrochronology is an interdisciplinary science, and its theory and techniques can be applied to many applications. See our subdisciplines for examples. These research interests have in common the following objectives:. Ring-counting does not ensure the accurate dating of each individual ring.

Solving the mesopotamia timeline puzzle with tree-rings and radiocarbon research -- ScienceDaily

What does the age of a tree have to do with the age of the earth? If, in fact, the oldest tree is years old, so what? Perhaps Dr. Hovind is impressed by the fact that such a tree would have sprouted at about the time Noah's flood ended. If that is the case, then it is time for a reality check. It might interest you to know that trees go back at least years without being disturbed by Noah's flood!

Solving the mesopotamia timeline puzzle with tree-rings and radiocarbon research

Tree-ring dating and radiocarbon research led by Cornell University archaeologist Sturt Manning has established an absolute timeline for the archaeological, historical and environmental record in Mesopotamia from the early second millennium B. Manning, the Goldwin Smith Professor of Classical Archaeology and director of the Cornell Tree-Ring Laboratory, resolved how to more accurately date the rich archaeological and textual record across years of ancient Near Eastern history -- the time of such famous figures as Hammurabi of Babylon. For several decades, scholars have debated discrepancies in chronological schemes for this period that were up to years or more apart. The previous inconsistencies in the timeline for ancient Mesopotamia stem from incomplete text records preserved on clay tablets, and existing, proposed and debated chronologies from other sources including partial astronomical records, archaeological materials such as ceramics, a tree-ring growth anomaly in Turkey originally thought to be caused by a volcanic eruption, and dates derived from radiocarbon dating. The multiple and often conflicting timelines have vexed historians and other scholars for a century.

Since , scientists have reckoned the ages of many old objects by measuring the amounts of radioactive carbon they contain. New research shows, however, that some estimates based on carbon may have erred by thousands of years. It is too soon to know whether the discovery will seriously upset the estimated dates of events like the arrival of human beings in the Western Hemisphere, scientists said. But it is already clear that the carbon method of dating will have to be recalibrated and corrected in some cases.
