Hello Coragyps,
as far as I know the institut for botanic at the university of Hohenheim (Germany) currently provides the most extended dendrochronology. It spans about 12.480 years; the period between present and 8480 BC is covered by 6000 oaks found in moors, the period between 7942 and 10.480 BC by pines found in gravel pits of rivers in South and East Germany. The institut plans to extend the chronology until 12365 BC, that is 14315 before present.
