# Bayesian chronological analyses consistent with synchronous age of 12,835–12,735 Cal B.P. for Younger Dryas boundary on four continents

James P. Kennett, Douglas J. Kennett, Brendan J. Culleton et al., 2015. _Proceedings of the National Academy of Sciences 112(32)_.

Bayesian modelling of 354 dates from 23 sections in 12 countries gives a boundary age of 12,835–12,735 cal BP (95%), which the authors say is consistent with synchronous deposition within about 100 years.
