Some of my samples from Dalkeith Old Oaks used to build a 450 year long oak chronology for South East #Scotland. Publication imminent. #FindsFriday #dendrochronology

Useful brain fart...
I was thinking about tree ring counting and estimating the age of a wood thing.
It occurred that the farther away from the core of the tree a ring is, the shallower the arc over a given distance and angle and average distance between rings.
Extrapolating, it may not be necessary to count each and every ring of a tree to estimate it's age. It can even be used on furnature.

A massive multi-stem oak which #Dendrochronology revealed has an early 19th C stem origin date. It looks much older. This is in the wood pasture ‘Dairy Wood’ at Borders Forest Trust’s Corehead estate near Moffat. #ThickTrunkTuesday #treeclub #trees
Tree rings and charred millet rewrite the Bronze Age history of Tabakoni in western Georgia. Precise dates reveal centuries of rebuilding, wetland farming, and persistence in the Colchian lowlands. #Archaeology #BronzeAge #Caucasus #Dendrochronology https://www.anthropology.net/p/timber-time-and-the-rise-of-a-mound

St Mary’s Haddington 🏴󠁧󠁢󠁳󠁣󠁴󠁿 has some remarkable medieval oak timbers in the nave roof. My #dendrochronology work there dated them to the early 1400s and revealed them as Baltic baulks from the Gdansk region. #MedievalMonday
