Surovell-Holliday 2012 Tusk commentary
Vance Holliday and Todd Surovell published a paper in PLOS One this week. It is unsurprising but again disappointing that these hacks continue their jihad on the YDB hypothesis based on negligent analysis.
Particular galling is their wanton substitution of an optical microscope for an electron microscope. I say “wanton” […]

In 2007, scientists proposed that the start of the Younger Dryas (YD) chronozone (10,900 radiocarbon years ago) and late Pleistocene extinctions resulted from the explosion of a comet in the […]
Obviously, this whole “salting” thing from The Bos has got me hopping mad — and for good reason.
By implying that the sites were “salted,” The Bos raises the issue of fraud or conspiracy surrounding the modern date he got on his YDB carbon spherule from Gainey, Michigan. But there’s a problem with that […]
ABSTRACT Intersection with the debris of a large (50-100 km) short-period comet during the Upper Palaeolithic provides a satisfactory explanation for the catastrophe of celestial origin which has been postulated to have occurred around 12900 BP, and which pre-saged a return to ice age conditions of duration 1300 years. The Taurid Complex appears to […]
[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 […]
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 […]
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 […]
Today’s press release from the University of Oregon complimenting yesterday’s from the University of South Carolina.
Surovell, et. al 2009 has another serious challenge here.
Challengers to Clovis-age impact theory missed key protocols, new study finds
EUGENE, Ore. — (Sept. 18, 2012) — An interdisciplinary team of scientists from seven U.S. institutions says a […]
These scientists have identified three contemporaneous levels more than 12,000 years ago, on two continents yielding siliceous scoria-like objects (SLO’s),” said H. Richard Lane, program director of National Science Foundation’s Division of Earth Sciences, which funded the research. “SLO’s are indicative of high-energy cosmic airbursts/impacts, bolstering the contention that these events induced […]

Distinguished Science writer Dr. Richard Kerr walked the plank this afternoon in response to this morning’s Knight Science Journalism Tracker inquiry of science writers.
Charles Petit’s casual post brought quick attention from the old-school dean of science writing. Kerr implored his press colleagues to, in effect: Move on, move on…There is nothing […]
