Culleton, and many others, 2015, Bayesian chronological analyses consistent with synchronous age of 12,835?12,735 Cal B.P. for Younger Dryas boundary on four continents.

Kennett, doi: 10.1073/pnas.1507146112 http://www.pnas.org/content/early/2015/07/21/1507146112.abstract Some related blog comments about it: >From the Journal of Younger Dryas Impact Hypothesis Studies Musings on Quantitative Palaeoecology, by Richard Telford https://quantpalaeo.wordpress.com/2015/07/28/from-the-journal-of-younger-dryas-impact-hypothesis-studies/ Another article of his is ?Platinum spikes extra-terrestrial impact as initiator of Younger Dryas Posted on 24/07/2013? https://quantpalaeo.wordpress.com/2013/07/24/extra-terrestrials-and-the-younger-dryas/comment-page-1/#comment-2822 There is an another paper, which found that the environmental changes that mark the beginning of the Younger Dryas are diachronous in their time of occurrence according to latitude. Along latitude 56?54?N, they ocurred as early as c. 12,900?13,100 cal. BP, while further north they ocurred at c. 12,600?12,750 cal. BP. This paper is: Muschitiello, F., and B.
