Őrtilos – Zrínyi-Újvár kútjából származó famaradványok dendrokronológiai vizsgálata

In summer 2017, a well was unearthed at the ar-chaeological site within the boundaries of Őrtilos, identified as Zrínyi Újvár. archaeologists hoped that the dendrochrono-logical analysis of the wooden remains would provide an exact dating of the site. Furthermore, they expected data for to de-cide whether there was an earlier fortification there and wheth-er that could be considered as the predecessor of Zrínyi Újvár. dendrochronological analysis included 23 samples, most of them coming from young and often injured trees. The used material was mainly pedunculate oak, a smaller part of the samples was made either of sessile oak, or of spruce. eight samples could be dated leading to the conclusion that the ma-terial of the well was cut not earlier than in 1658.
