Newton’s Great Comet of 1680
Update: A couple of useful links and a popular article on the subject.
I just learned of the discovery of Comet ISON which has apparently electrified the astronomy world for months. What then caught my eye was a paper from David Eichler of Ben Gurion […]
A Mike Baillie fan passed along this fascinating discovery last week and I hoisted the paper to Scribd and the Tusk immediately. Mike is on to something mighty interesting. Nowhere has anyone noted the corellation between the two early Mayan “Baktun” transitions and spikes in ice core chemistry from Greenland.
The wisdom of crowds is comforting. Despite the near total news blackout of the recent developments related to our subject, readers have shot Anders Carlson’s 2010 free paper, What Caused the Younger Dryas Cold Event?, to the top of the Most Read articles in the journal Geology.
I am not surprised. This is an absolutely […]
Nice blurb in Natural History Magazine this month. Still not sure if there is a longer article behind it in the print or on-line editions. Perhaps not, which would be a shame because Natural History is a fine magazine. It was one of those magazines you could buy when there were still bookstores where you […]
They are still cleaning up the dropped jaws at Charlotte GSA. (Because of the formatting the poster is best viewed by clicking “download” in the upper left and viewing the file itself.)

E.P. Grondine was kind to contact me this morning with a thoughtful “Is everything OK?” query. Emphatically yes, and that is the problem. My business and civic life, as balanced with young family, have been all consuming for me of late. Our company just signed a very, very large contract and I have recently been […]
I hate being dragged into these “modern” reports, since the Tusk specializes about this kind of stuff in the ancient past. But the UK event yesterday was really, really cool and I have posted before on these slow greenish fireballs.
Because of the unusually long duration and slow movement, some people […]
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 […]

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 […]
LIVE UPDATE: See here to watch tonight for the potential scar of the impact.
The Tusk focuses laser-like on impacts experienced by ancient humans. But when called for, I share items from current events that prove our thesis that the rate of cosmic collisions is far greater than generally acknowledged by science (and […]
