Grab an oar: Comet Research Group crowd appeal goes live on Indiegogo

November 14, 2016

Hey folks, I will make this short and expand and update in the future. The newly formed Comet Research Group crowd appeal for funding ancient impact research is on the air — and your help is desperately needed. Now is the time for all good men to come to the aid of the Tusk. And […]

Comet Research Group crowdfunding appeal reschedules launch to Monday, November 14th: Graham Hancock to appear on Joe Rogan podcast Tuesday the 15th

November 11, 2016

The Comet Research Group crowdfunding effort announced on the Tusk last month, and originally scheduled for November 1st, was pushed back in the interest of avoiding the pending election hysteria. The new date of Monday, November 14th also helps place the launch at a more promising time, a day before a key appearance of author Graham […]

Big News: Crowdfunding appeal coming November 1st [Now 14th!] for new 'Comet Research Group'

October 5, 2016

The Tusk has an exciting announcement. For many months a project has been underway to develop a crowdfunding campaign to finance a significant and continuing expansion of research into the YDB impact and related phenomena. Drs. Allen West, Ted Bunch, Chris Moore and I are directing the effort, which launches on November 1 and will introduce […]

Awkward but promising: Compromise paper from Andronikov & Van Hoesel

September 10, 2016

The presence of a possible meteoritic component in the same sediments suggests that an ET event occurred at approximately the same time. However, whether the presence of the meteoritic component is due to a local meteorite impact/airburst or to a much stronger event remains unclear. Anyway, it is quite possible that some short and dramatic event […]

Close to home

  Regular readers of the Tusk know we don’t dwell here on modern day cosmic interactions. But that was yesterday. Today a best buddy and long-time co-worker, Worth Creech, came into my office shocked to report….he had actually seen…..a daytime fireball in Raleigh! Well, I’ll bee. The Tar Heel State had an encounter with the […]

Here They Go Again: Holliday and Surovell use dozer not trowel

July 13, 2016

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” because […]

Whatapaper: Baillie and McAneney on the Bronze Age Cosmic Collapse

May 14, 2016

Mandelkehr Kobres Below is a superbly written exploration of the climate collapse(s) circa. 2200 B.C. by occasional Tusk commentor Jonny McAneney and his mentor, long-time Tusk favorite Mike Baillie. I don’t know how I missed this paper, but I do know how I found it. Jonny thoughtfully posted the public link back in December 15, […]

University of Arizona confirms spherule concentration in lower YDB sediments at famed Clovis site Blackwater Draw

February 26, 2016

  Blackwater Draw The presence of a high number of the hollow magnetic microspherules can be used for identification of the LYDB. Although some scientists failed to find any microspherules at all along the LYDB in the BWD-1 site (Surovell et al. 2009), others reported strongly elevated concentrations of the magnetic microspherules here (Firestone et al. 2007; LeCompte et al.

Kloosterman: A man before his time

December 17, 2015

Kloosterman Trevor Palmer and the fine folks across the pond at the Society for Interdisciplinary Studies were thoughtful to contribute a newly translated 2000 monograph by Tusk favorite, Dutchman Han Kloosterman. It is a wonderfully prescient and learned piece that places Kloosterman’s field evidence (the Usselo layer) into centuries of context for catastrophic geology. The publication […]
