The fact that carbon-dated results match with tree-ring dating is not a fundamental pillar of dendrochronology, only an additional support. | :::* On the matter of dendrochronology and other methods being used in circular logic: [http://www.wsl.ch/staff/felix.kaiser/PDFs/Friedrich_Dendro_RC04%20.pdf this source], as well as others online, show that carbon dating and other methods are calibrated off of tree-ring records, and that the trees' ages are not based off of other methods.
