Will the find in Zurich-Binz bridge the data gap?

The Central European absolutely dated tree-ring chronology (blue in the graph below) is based on oak and pine trees and ends around 12,500 years before present.

Scientists hope that the new find will enable them to extend it a further 1,500 years back into the late-glacial period (click on graph for larger version).
