How reliable is dendrochronology?
It is an accurate and reliable dating method with a large number of uses in environmental studies, archaeology and everything in between. The method has gone from strength to strength and is now a vital method across multiple disciplines.
Which is the oldest tree in the world?
The Great Basin Bristlecone Pine (Pinus Longaeva) has been deemed the oldest tree in existence, reaching an age of over 5,000 years old.
How far back can dendrochronology date?

What exactly does dendrochronology attempt to date?
Crossdating is the most basic principle of dendrochronology. Crossdating is a technique that ensures each individual tree ring is assigned its exact year of formation. This is accomplished by matching patterns of wide and narrow rings between cores from the same tree, and between trees from different locations.
How is dendrochronology useful?
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 are 2 disadvantages or limitations of tree rings?
Some of those limitations include: In some areas of the world, particularly in the tropics, the species available do not have sufficiently distinct seasonal patterns that they can be used. Where the right species are available, the wood must be well enough preserved that the rings are readable.
