[See comments: Boslough responds!]
Boslough et al’s recent paper gives no less than nine separate citations to Todd Surovell’s 2009 publication: An independent evaluation of the Younger Dryas extra-terrestrial hypothesis. The multiple references are not surprising given that the Surovell paper has become a totem of Boslough and other’s crusade to end research into the […]
I have seen some fawning press releases in my day but this is the most obsequious schlock I have ever encountered. Mark or his mum must have stayed up real late writing this one. I seriously doubt any synthesis rebuttal paper containing so little original work (What did kill all those animals? Global warming?) has ever […]
To a great degree the Tusk itself was a response to my frustration with Todd Surovell and Vance Holliday’s botched 2009 PNAS journal article, “An independent evaluation of the Younger Dryas extraterrestrial impact hypothesis,” published three months before this blog began.
Despite my early understanding of the sloppy work of the authors, however, I did […]

This appears to be the long hoped for independent, intentional, blind, professional and reproducible confirmation of the original 2007 findings of the Younger Dryas Boundary team.
Independent evaluation of conflicting microspherule results from different investigations of the Younger Dryas […]
I’ll soon have the actual paper, but below is Sid Perkin’s take at Science Magazine. The news article itself already reveals what appears to be a fundamental misunderstanding of the YDB team’s previous results. The YDB team does not claim the blast spherules are from space. They believe they are terrestrial. The Lake Cuitzeo […]
