Ice core data might provide an interesting test. Smash the dendro temperature values (these are probably available even if the measurements aren’t) into shards, and then use techniques of the “shotgun sequencing” variety to reassemble it against the continuous ice core data template. See how it falls into place when there is no human dictating the dates.
Is there ice core data to cover the gap?
EDIT: radiometric dating would present another big problem for this thesis. Still, it’s very unfortunate that the dendrochronology data isn’t public.
