Subfossil trunks are unfossilized woods which are discovered rarely in the Czech Republic. The aim of this work was to find, sampled and dated subfossil trunks from the Polabí region. Available Czech and foreign standard chronologies were used for dendrochronological dating of tree-ring series. Simultaneously, earlier sampled subfossil trunks from the study area were assembled. The chosen tree-ring series were used to extension and improvement of the Czech oak standard chronology. Selected samples, which were not possible to dendochronologically date, were sent for radiocarbon dating. For a purpose of this work, 122 new subfossil findings were dendrochronologically processed from the Polabí region and three samples were prepared and sent for radiocarbon dating. The major part of subfossil trunks was identified as an oak and only 5 samples as an elm. In total, 96 samples were successfully dated mostly into two periods: 3500 - 3200 BC and 133 BC - 155 AD. In Kostomlátky location, the oldest oak subfossil trunk in the Czech republic was found the tree-ring series covers the period 8181 7971 BC. Thanks to these subfossil findings, the Czech oak standard chronology could be extended.
