NY Post Gizmodo Quartz Francis Thackeray My PDF embed widget is down, but the paper can be seen here: Did a large meteorite hit the earth 12,800 years ago? Here’s new evidence Shutterstock Francis Thackeray, University of the Witwatersrand Just less than 13,000 years ago, the climate cooled for a short while in many parts […]

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 […]

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, […]

Long on the list of goals here at the Tusk is to host the world’s most concise, attractive, accessible and informative bibliography of our favorite subject. A baby step in that direction is submitted below for your perusal, download and propagation. With the help of Marc Young, here is a list of what we believe […]

Martin Sweatman, like The Bos, is a betting man. But in this instance I want his side of the wager. Today Sweatman published a masterpiece of original, rational statical analysis reporting a series of planetary catastrophes as recorded by our elders in ancient symbols in cave art and carved rock. The historic rejection of ancient animal […]

Bos Bet… Voosen article in Science Magazine Seven Ages Daily Mail National Geographic BBC NYT MSN Oh, happy day! The Tusk heard about this discovery confidentially in March but the following nine months were characterized by an uncertain confidence this day would truly come. We had published evidence for a decade, and knew a climate […]

See another blockbuster confirmation of the Younger Dryas cosmic impact below. I keep a pretty close eye on our subject but had no idea such intricate, original and thorough work was underway in the Czech Republic. Gunther Kleteschka has appeared on several YDB papers, but has clearly been busy in his own laboratory collecting entirely […]

I realize that this subject is distasteful to many because of the early false claims. But the new evidence suggests that there was some kind of extraterrestrial impact. Hence it should be given further study.   What a significant and pleasing development. Wally Broecker has endorsed a cosmic impact as the cause of the Younger […]

A friend sent me this paper from Dr. Martin Sweatman who gained international notoriety last year with a previous journal article linking the world’s most ancient temple, Gobekli Tepe in Turkey, with the Younger Dryas Impact. The Tusk enjoyed that paper and was pleased to see Sweatman make a second contribution to our field; this […]

This week Rick Firestone shared a little known 2009 paper with the Tusk and some others. I was unaware of it and enjoyed reading it. The authors find a unique spike in fire at Akgol, Turkey ~13,000 years ago which they attribute to a horrendous inferno in a marsh, of all places. They cite Firestone […]

Papers #1 and #2 and Supplementary Materials Quick take at skeptic site NeuroLogica Tallboy – Widespread Panic (1997) The Tusk inaugurates our new look here by posting the most important paper in the peer-reviewed canon of the Comet Research Group since the original PNAS publication in 2007. It is truly a new day at the […]

A. Zamora The Tusk was absolutely thrilled to see the publication last week of a paper concerning Carolina Bays in the distinguished journal, Geomorphology. Other than a brief role for the Carolina bays in the early papers of the Comet Research Group, and a much longer series of Geological Society of America posters laboriously researched […]
