In Central Europe, the dendrochronological method in absolute dating is widely used, but a significant difficulty in its application is the lack of pine (Pinus sylvestris) chronologies reaching back more than tenth century CE. Recently, long floating pine chronologies covering the last thousand years of the BCE were compiled at the Dendrochronological Laboratory of AGH University of Science and Technology in Krakow. These are mean curves developed from hundreds of trunks of subfossil trees found in Polish peatlands. They were preliminarily dated using the wiggle-matching method. Later, rapid Δ¹⁴C changes at 660 BCE and at 814-813 BCE were used for their precise dating with annual precision.
