A paper by Jessica Blois, Jack Williams, Eric Grimm, Steve Jackson, and Russ Graham has just been published in Quaternary Science Reviews. This paper uses the Neotoma database to assess the amount of temporal uncertainty in late Quaternary pollen cores from eastern North America. The authors then identify particularly well-dated and well-sampled sites ('benchmark' sites), and use them to update the age-models of nearby, non-benchmark sites.
