Catastrophism news

That YD boundary event squabble, once again

As noted a week or so ago, George Howard at http://cosmictusk.com/wittke_pnas_younger_dryas_clovis_comet/ ... posted news of a fresh paper on the YD event. So far he has only the news release and list of co-authors (which include himself). However, another of the co-author's, Kenneth Tankersley of the University of Cincinatti, has been giving his pennyworth -see www.world-science.net/othernews/130520_mammoth.htm

Subfossil forest found in Zurich clay layer

Interesting piece of geology this - the remains of an Alpine forest found in a clay layer. How long did it take the clay to form?

The Secret History of Twin Planet Earth

A revised edition of the Secret History of Twin Planet Earth by Errol Hawkins (2007) - see http://malagabay.wordpress.com/2013/04/29/secret-history-of-twin-planet-... ... and www.secrethistoryoftwinplanetearth.net/ ... which is an interesting take on catastrophism - and the Velikovskian history of the solar system. The Earth and Moon came together just 45 to 50,000 years ago, is one of the ideas explored - and it flows out from there.

Space rocks on the Moon

At www.space.com/21306-moon-craters-asteroid-impacts.html ... a quarter of the Moon's impact craters may retain substantial remnants of the asteroids and meteors that made them. In other words, when scientists claim to be looking at moon rocks - are they? The composition of the Moon has been deduced from Moon rocks brought back by expeditions - manned and unmanned. The problem is some of those moon rocks come from impact craters and could well belong to asteroids and rocks winging their way around the solar system.

Younger Dryas Update May 2013

At http://cosmictusk.com/wittke_pnas_younger_dryas_clovis_comet/ ... a new paper published in PNAS - George says it is the best yet. This time impact is discarded in favour of multiple airbursts by a disintegrating comet or space rock. The thrust of the article is a riposte to criticism of their methodology so they have gone back to the laboratory in order to stress the point it is all above board. They have collated an assemblage of what they say is impact related proxies - such as microspherules, nanodiamonds, and iridium.

The comets of gods

Dr Jeffrey Goodman, The Comets of Gods (available from Amazon in ebook form (for Kindle) but provides a list of sellers (hard copy). This is an attempt to mold catastrophism, from a Biblical perspective, with some parts of science (comets and space rocks etc). It is mooted that God (in the Bible) used objects from space to carry out his bidding.

Younger Dryas - species survival

At http://cosmictusk.com/sheridan-cave-down-but-not-out/ there is a link to a paper in Current Research in the Pleistocene, 28 (2011), Redmond and Tankersley, 'Species Response to the Theorised Clovis Comet Impact at Sheridan Cave, Ohio' say that of 63 flora and faunal taxa recovered from the boundary layer 52 species of amphibians, plants, fish, mammals and reptiles were unaffected by the Clovis come and still thrive in the immediate vicinity of the cave.

Toba Super Volcano

At last the Toba super volcano catastrophe idea has been squelched - see www.bbc.co.uk/news/science-environment-22355515

Ancient Lead Levels

At http://phys.org/print286532235.html ... a lake in Iberia, in the Sierra Nevada, over 3000m above sea level, has revealed evidence of atmospheric polution around 2000BC. The researchers have blamed the polution on humans as they also seem to have found high lead levels in the Roman period. They are saying that metal smiths in the Early Bronze Age were responsible, on the assumption a great deal of bronze making was going on in Spain and Portugal.

Why did European DNA change 4000 plus years ago?

Is this a bit of Daily Wail fluff or a piece of spin on a string - or is there something important to be learned - see www.dailymail.co.uk/sciencetech/article-2313677/Why-did-Europeans-sudden... ... and the clue might actually be in the addition of Stonehenge - sure to scratch some heads. However, the same story pops up at www.geneticarchaeology.com/research/Ancient_DNA_reveals_Europes_dynamic_... ...
