Ein #Sammlungsstück zu den heutigen Hashtags: Kein echtes #Fossil - subfossil, noch nicht #versteinert , aber dabei 😁

Ein gut 6.000 Jahre altes Stück #Holz 🪵 aus der #Elbe in Tschechien, bei dem man die #Jahresringe als hellere und dunklere Linien erkennen kann. So kann man nicht nur die vorgeschichtlichen Temperaturen 🌡️ ablesen, sondern per #Dendrochronologie auch das Alter bestimmen 🧙‍♂️

Delighted to have the chance to write this blog for Murray, with a focus on #dendrochronology in and around Stirling

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.

Thanks for sharing Mark. I enjoyed being interviewed by Vincent Reed for this podcast. #dendrochronology #Scotland

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
