Things start moving regarding the dendro bridge over the Roman gap

In a new article in Dendrochronologia, Andreas Rzepecki with co-authors lift the lid on Ernst Hollstein's weak bridge over the Roman gap in the Central European oak chronology. This issue has been taboo since the bridge was accepted by academia. However, the authors do not deliver any scientific proof for their assertion that the bridge is still valid.

Our analysis shows that the generally used confidence levels for dendrochronological matches are still far too low to point out an unambiguous synchronous position. And in cases when a strong confidence level can not be reached with dendrochronology, the use of less resolved methods like radiocarbon, or even worse historical considerations, is still regarded an adequate procedure.
