New clues about Earth’s most elusive impact crater
Cavosie, A.J., N.E. Timms, T.M. Erickson, and C. Koeberl, 2017,
New clues from Earth’s most elusive impact crater: Evidence
of reidite in Australasian tektites from Thailand. Geology
Published: December 20, 2017 DOI: https://doi.org/10.1130/G39711.1
https://pubs.geoscienceworld.org/gsa/geology/article-abstract/525531/new-clues-from-earth-s-most-elusive-impact-crater?
" Here we report new evidence of a rare high-pressure
phase in Australasian tektites that further constrains
the location of the source crater. The former presence
of reidite, a high-pressure polymorph of zircon, was
detected in granular zircon grains within Muong
Nong–type tektites from Thailand."
"The data presented here place further constraints on the
distribution of high-pressure phases in Australasian tektites,
including coesite and now reidite, to an area centered over
Southeast Asia, which appears to be the most likely location
of the source crater."

More Comments by Graham Hancock About Younger Dryas Impact Hypothesis
More Comments by Graham Hancock About Younger Dryas Impact Hypothesis
Popular writer and fringe archaeologist Graham Hancock has written a new and extended commentary
about the Younger Dryas Impact Hypothesis. He is quite unhappy about he believes that he and other proponents of this hypothesis have been treated by so-called “gradualists” whoever they are, within the scientific community. The commentary is at:
Why Science Should Cherish Its Rebels by Graham Hancock

Contrary to what Mr. Hancock seems to believe, neocatastrophism has become popular among
geologists and scientists as discussed in:
Marriner, N., Morhange, C. and Skrimshire, S., 2010. Geoscience meets the four horsemen?: Tracking the rise of neocatastrophism. Global and Planetary Change, 74(1), pp.43-48.
https://www.researchgate.net/publication/222537265_Geoscience_meets_the_four_horsemen_Tracking_the_rise_of_neocatastrophism
One item that Jason Calavito did not mention in his commentaries, is that Mr. Hancock does not appreciate the significance of recent research about the chronology of the Missoula (Spokane) Floods and older “Ancient Cataclysmic Floods.” The identification of numerous Missoula Floods has nothing to do with any imaginary conspiracy by an equally imaginary cabal of nameless “gradualists.” Rather the recognition is based upon multiple, unconformity-bounded sets of flood deposits. These flood deposits are separated subaerial exposure surfaces in which paleosols, including some very well-developed calcretes, and terrestrial animals burrows have developed. There also are separate sets of clastic dikes truncated at different unconformities. Some of different sets of flood deposits have been
dated using, where possible, by radiocarbon dating magnetostratigraphy, optically stimulated luminescence dating, and tephrachronology. The oldest of these deposits predate 1.77 million years ago. There exists an abundance of published evidence that demonstrates the occurrence of innumerable Missoula-like megafloods over a period greater than 1.77 million years.
Also, Mr. Hancock overlooks Antonio Zamora ‘s badly flawed optically stimulated luminescence arguments that ignores the context of these dates and collaborating pollen records from the fills of the Carolina Bays.
Finally, Mr. Hancock is seemingly unaware of the lack of any credible evidence supporting the existence of Michael Davias’ seemingly imaginary Saginaw Bay impact structure that is used to explain the Carolina Bays. The geology that region is well known enough to show that there is a complete lack of the deformation of bedrock and overlying Quaternary deposits that such an impact would have caused. Also, any geophysical signature ot such as impact structure is lacking. Finally, regional
sedimentary and paleoenvironmental archives for that time period lack and are undisturbed by the ejecta deposits that such an impact would have created. The Saginaw Bay impact structure is just one of a few likely imaginary Pleistocene impact craters that have been reported in the Great lakes region.

Paul H

http://www.hallofmaat.com/read.php?1,611196
The paper seemed like an exercise in speculation and personal opinion lacking a firm basis in evidence
and unconstrained by what other researchers have published and documented.They certainly failed to consider what modern geologists have written in published peer-reviewed articles in plain English in reference to Spokane / Missoula Flood as seen in the statement:
"Analysis of the geology of the Scablands and similar features across North America indicating
sudden melting of the Laurentide ice sheet and immense flooding across large areas of North America."
The fact of the matter is that the "analysis of the geology of the Scablands and similar features
across North America" had shown that the Laurentide ice sheet did **not** suddenly melt at the time of their alleged impact. It has been clearly demonstrated that there has been multiple Missoula Floods over the past 1.5 to 2 million years and that the significant flooding events predate the hypothesized Younger Dryas Impact event. At least, in respect to the Missoula Floods, their ideas are unconstrained by the known evidence.

The T-Rex of Prehistoric Earthworms or Pseudofossil?
The T-Rex of Prehistoric Earthworms or Pseudofossil?
I know that this is off-topic. However, it is not often that a person finds a rock that is weirder than a meteorite. Scientists cannot even agree whether it is a fossil or not.
The latest theory is that this rock is the fossil of the T-Rex of earthworms. Go see the open access paper at:

in North America: a novel palaeobiological alternative to inorganic morphogenesis. Lethaia, Vol. 50, 194–216.

Meteorwrongs are common compared to the above pseudofossils / fossil earthworm. :-)
