Permanent Younger Dryas Impact Paper Archive and Bibliography

November 8, 2019

Welcome to the permanent host page for the most comprehensive bibliography of scientific literature concerning the Younger Dryas Impact Hypothesis. The bibliography was compiled in a collaboration between the Tusk and Mr. Marc Young, an Australian Archaeology & Enviro-Sci undergrad who performed most of the meticulous work. Significantly, this page will include not only the […]

Tusk challenges Rogan to question Tyson regarding the Younger Dryas Impact Hypothesis

November 6, 2019

  The Tusk recently appeared as a guest on the UnchartedX YouTube series. It was fun and I have a lot of respect for Ben’s work to publicize the YDIH and the Comet Research Group. But if had to do the podcast over again, I would have made more than a passing reference to an […]

Sweatman rolls out Younger Dryas Impact Lit Review 2nd Edition

Randall on Halloween

October 31, 2019

Randall Carlson does a great job here explaining a really creepy but profound aspect of the Younger Dryas Impact Hypothesis. Halloween, like death festivals worldwide in late October\early November, reflects the trauma inflicted by the Taurid Meteor stream on the ancients during recurring bombardments. As Bill Napier described it once to me, Earth’s intersection with […]

October 29, 2019

James T. Teller The Younger Dryas Impact Hypothesis achieved its first publishing “Three-Peat” of supportive papers this month.

Bibliography and Paper Archive Permanent Page

October 27, 2019

Readers may recall a few months ago the Tusk and Australian university student Marc Young compiled a bibliography and archive file of all the YDIH publications since the seminal PNAS publication in 2007. I have taken the files and given them a permanent home here. The publication history of the subject is a long and […]

October 24, 2019

  New evidence that an extraterrestrial collision 12,800 years ago triggered an abrupt climate change for Earth The muck that’s been accumulating at the bottom of this lake for 20,000 years is like a climate time capsule. Christopher R. Moore, University of South Carolina What kicked off the Earth’s rapid cooling 12,800 years ago? In […]

YDIH Literature Review Part One

Martin Sweatman goes deep into Younger Dryas bibliography 2007 - 2009

October 20, 2019

Martin Sweatman, when not writing a profound book, is building quite a nice catalog of videos concerning the YDIH and related subjects. This one is particularly welcome and represents the best walk-though of the debate, paper by paper, twist by turn, since Hancock’s careful narration here. This is invaluable science communication and should be viewed […]

YouTuber explains worldwide religion in context of the Younger Dryas impact

October 12, 2019

Tusk video from Tall el-Hammam Ben at UnchartedX continues to produce excellent videos concerning the Younger Dryas Cataclysm and related subjects. Just recently he posted this superbly produced review of religious and mythical information and how it perfectly matches the hard science of impacts. Warning: This stuff is heavy, and as Ben points out, it […]

Younger Dryas Impact Platinum peaks found again in Southern Hemisphere

October 2, 2019

NY Post Gizmodo Quartz Francis Thackeray   This confirmation of a South African platinum layer from the Younger Dryas Impact was particularly welcome for several reasons.  First, it is another confirmation of evidence for  the impact in the Southern Hemisphere, following the Pilauco paper from Chile in March of this year. Second, the lead author, […]

Napier Paper

Dr. Bill Napier fingers fragmented comet in Younger Dryas and Bronze Age impacts

August 21, 2019

Folks, I am sorry to have been so scarce in recent months. Among other excuses for the inexcusable, the auto-mailer for subscribers to the site went down, and I felt I needed to repair it before posting. Fixing it turned into a mess which led to my continued procrastination. Much has happened in recent months […]

Peter Brown publishes Taurid threat paper, dusts The Bos

May 24, 2019

An instructive video accompanies the paper I’m trying to get out of town for a beach weekend, but I’ve wanted to get this paper up for days. The newly prominent role of the Taurids among American space scientists, with the role of The Bos discussed in a recent Tusk post here, is peculiar but not […]

Book Review: Prehistory Decoded

By Dr. Martin Sweatman

April 25, 2019

Any follower of Catastrophism the last few years has seen extraordinary confirmations of ancient cataclysm and novel contributions to our way of thinking. To the Tusk, three revelations have characterized the period: The discovery of an extraordinarily youthful late Pleistocene crater in Greenland; a series of popular, comprehensive and unrefuted major journal articles with exquisite hard evidence for the Younger Dryas impact catastrophe; and the singular contribution of Dr. Martin Sweatman, as made in his fabulous book, Prehistory Decoded.

Younger Dryas Boundary team publishes evidence from Chile in Nature for global climate cataclysm

March 14, 2019

The main objective of this study was to test the YDB impact hypothesis by analyzing a wide range of data from the Pilauco site in southern Chile. The following conclusions show that our data and interpretations are consistent with the YDB impact hypothesis and we found no evidence that refutes the hypothesis. (1) At Pilauco, […]

Ancient tree and plant parts found in Greenland's youthful Hiawatha Crater

Dr. Kurt Kjaer collecting samples at Hiawatha Crater

February 25, 2019

The large variety of Hiawatha impactite grains containing terrestrial organic matter with a likely age between 2.5 Ma and 50 ka support the conclusion in [1] that the crater itself is not much eroded and very young, and the possibility of an age of less than 50 ka remains open.  

Protesteth too much...

Vance Holliday disguises rant as lecture

February 24, 2019

The bibliography of the subject alone refutes Vance Holliday’s absolute and categorical rejection of all evidence for the YDIH in a recent lecture. There are simply too many groups publishing too many papers for all of the evidence to be entirely rejected by anyone, even a persistent critic like Holliday. For gosh sake, the world’s […]
