Dendrochronology is an invaluable tool to help scientists determine the age of ancient settlements and artifacts. Archaeologists have a group of unlikely allies: trees. Dendrochronology, the scientific method of studying tree rings, can pinpoint the age of archaeological sites using information stored inside old wood.
What is dendrochronology and what information does it provide about past climates?
Dendrochronology is a scientific method that uses the annual growth rings on trees to find out the exact year the tree was formed, which helps scientists date events, environmental change, and archaeological artifacts. In temperate climates, a tree will grow one ring each year.
Where can dendrochronology be used?
It also gives data on the timing of events and rates of change in the environment (most prominently climate) and also in wood found in archaeology or works of art and architecture, such as old panel paintings. It is also used as a check in radiocarbon dating to calibrate radiocarbon ages.
What is the longest living tree on earth?
Great Basin bristlecone pine *With its date finally confirmed in 2012, there is one other Great Basin bristlecone pine thats actually older (5,069 years old as of 2021—born around the time of the invention of the wheel), but the exact location of this healthy, unnamed specimen has been kept secret.
Who is called Dendrochronologist?
Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed. As well as dating them, this can give data for dendroclimatology, the study of climate and atmospheric conditions during different periods in history from wood.
What are the limits of dendrochronology?
In dendrochronology, the most serious limitation is that more variables affect tree growth and health than just moisture availability. Tree growth itself is very complex, as is interaction with the surrounding environment.
