According to David Rohl, the Sweet Track chronology from Southwest England was ‘re-measured’ when it did not agree with the published dendrochronology from Northern Ireland (Belfast).

It is clear that dendrochronology is not a clear-cut, objective dating method despite the extravagant claims of some of its advocates. The internet, and this site in particular, can be a powerful tool for reaching those who would never go to church.

Extended tree ring chronology is not an independent confirmation/calibration of carbon dating earlier than historically validated dates, as has been claimed. Keep the penetration going by supporting this outreach.

The extended tree ring chronologies are far from absolute, in spite of the popular hype.

To illustrate this we only have to consider the publication and subsequent withdrawal of two European tree-ring chronologies.

There are many points in a given sequence where a sequence from a new piece of wood matches well (note that even two trees growing next to each other will not have recognized that ring pattern matches are not unique.

The best match (using statistical tests) is often rejected in favour of a less exact match because the best match is deemed to be ‘incorrect’ (particularly if it is too far away from the carbon-14 ‘age’).

If you possess published/unpublished radiocarbon or dendro dates from Irish sites and would like to see them disseminated to a wider audience, please feel free to contact the author at If you have other dates, either from your own excavations, of have found in other published sources, I'd also be grateful if they could passed on to me for inclusion in future releases of this document.

I worked as a dendrochronologist at the National Museum of Denmark for seven years and then as an independent freelance dendrochronologist. studies from the Danish Research Council, which I carried out fulltime for three years (2004-2007) at the University of Southern Denmark, and was awarded the degree in 2007.

In 2003, I was awarded a grant from the Elisabeth Munksgaard Fund, Denmark, for the preparation of the paper 'The dendrochronological dating of timber crossings in west Jutland, Denmark', which is published in the peer-reviewed Journal of Wetland Archaeology, 2006. In my thesis, 'Timber, Trade and Tree-rings', I refined the method in which dendrochronology is used to determine the area of origin of timbers, found in archaeological/historical contexts.

So the carbon ‘date’ is used to constrain just which match is acceptable.
