Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed in a tree. As well as dating them, this can give data for dendroclimatology , the study of climate and atmospheric conditions during different periods in history from the wood of old trees.
The first table includes trees for which a minimum age has been directly determined, either through counting or cross-referencing tree rings or through radiocarbon dating. Many of these trees may be even older than their listed ages, but the oldest wood in the tree has rotted away. For some old trees, so much of the center is missing that their ...
The Sweet Track, ancient timber roadway of England (oldest engineered road yet discovered) 3374 BCE: Tree-ring dating of find site layer at Arslantepe-Malatya; the cylinder seal unearthed contains an image of a threshing-board or sledge; 2049 BCE: Seahenge constructed in Britain; 2300 to 1950 BCE, 1950 to 1700 BCE

The tree has a height of 25.3 m (83 ft) and a trunk circumference of 16.4 m (54 ft). [13] It has a volume of approximately 300 m 3 (11,000 cu ft), making it the largest conifer in Japan. [1] Tree-ring dating conducted by Japanese scientists on the tree's branches indicated that Jōmon Sugi is at least 2,000 years old. [1]
Bristlecone pines are invaluable to dendroclimatologists, because they provide the longest continual climatically sensitive tree-ring chronologies on Earth. By cross-dating millennia-old bristlecone pine debris, some chronologies reach beyond 9,000 years before present. [8] In addition, ratios of stable carbon isotopes from bristlecone pine ...

Dendroarchaeology is a term used for the study of vegetation remains, old buildings, artifacts, furniture, art and musical instruments using the techniques of dendrochronology (tree-ring dating). It refers to dendrochronological research of wood from the past regardless of its current physical context (in or above the soil).
