Awkward but promising: Compromise paper from Andronikov & Van Hoesel

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 […]

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

 

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 […]

Kloosterman: A man before his time

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 […]

#YDB impact confirmed again: Volcanos and Asteroids and Mammoths — Oh My!

My dear Kepler, I wish that we might laugh at the remarkable stupidity of the common herd. What do you have to say about the principal philosophers of this academy who are filled with the stubbornness of an asp and do not want to look at either the planets, the moon or the telescope, […]

Loose Goose: The Bos all over the map

Long ago the Tusk noted a fascinating 2010 missive from The Bos concerning the virtue of everyone (else) remaining intellectually flexible. Or, as he put it, having a willingness to “change your mind.” Here is the link and I have copied the text at the bottom.

The Bos’ statement has not aged […]

Nice Dice?: The Bos disputes Harvard

It is safe to say The Bos is becoming obsessed. Someone please count and let me know, but I believe he has four publications this year seeking to undermine the Younger Dryas Boundary Hypothesis. Over time he has published more than a dozen. Today he is back in PNAS — alone — […]

Broecker to Kunzig: This Deal is Real

Readers will recall the awkwardly titled September post, “NatGeo actually calls Wally Broecker to discuss evidence for cosmic impact at Younger Dryas start.” The Tusk was trying to convey there my astonishment that a thoughtful and thorough article was written on recent advances in the study of the Younger Dryas Boundary. Only […]
