pretty impressive piece of rock on the island of Santiago in the Cape Verde Islands. It is the result of a tsunami wave caused by the side of a volcano blowing out on the nearby island of Fogo. It took place 70,000 years ago - it is thought. See www.theatlantic.com/science/archive/2015/10/traces-of-an-ancient-mega-ts...
Yes, the claim that stone age humans had the ability to bring about the demise of Ice Age animal life is up and running once again. At http://phys.org/print364718233.html ... new data presented at the conference of the Society of Vertebrate Palaeontology in Dallas in October (2015) has provided the spark to trot out the theory once again. Apparently, the fact that early Aborigines were living in Australia prior to the extinction event between 40 and 27,000 years ago is all they needed to point the finger.
On a similar theme, at http://phys.org/print364584736.html ... according to a study in the Monthly Notices of the Royal Astronomical Society, Michael Rampino (a geologist) and Ken Caldeira (ecologist) claim mass extinctions can be linked to known craters over the last 260 million years (including the Chicxulub crater in Yucatan). Specifically, they set out to show a cyclical pattern over the studied period with both impact craters and extinction events juxtaposed close to each other every 26 million years of time.
It seems that Andrew Fitt has jumped the gun and invited Ruth Dwyer to speak at the upcoming Toronto conference in May of next year (2016). She will join speakers such as Irving Wolfe and Gunnar Heinsohn - but more names are in the pipeline. If you have relatives in Ontario take the opportunity to visit them in May and include the conference in your itinerary. It seems she is not going to speak at the conference now.
I haven't seen them all yet but there are six videos posted on YouTube by Ruth Dwyer - see for instance https://www.youtube.com/watch?v=0POfUod85Wk ... but hat tip to Anne Marie de Grazia at www.q-mag.org/ruth-dwyer-the-comet-of-536-and-the-ravenna-mosaics/ ... and since then posted by Clark Whelton.
Catastrophism is back on the nose at George Howard's place - go to http://cosmictusk.com/wow/ ... and one word says it all as unusual silicate glass was found in the Atacama Desert in northern Chile. The melted rock fragments litter the ground at several locations. They possess a stable remanent magnetism carried by fine grained magnetite aquired during cooling (of the heated silicate). Basically, some sediments were heated to form a bank or layer up to 20cm thick, and they were heated up by very high temperatures.
I see migrations as part of Catastrophism as major catastrophic events inspire people, out of fear of their safety, and that of their loved ones, to get the hell out of where they are living. Safe havens have often been the Egyptian delta for example, with birds and fish in abundance. However, migrations can be inspired for purely economic reasons, as occurred during the Middle Kingdom period (lots of foreigners entered Egypt in order to enjoy a better standard of living). This was not necessarily inspired by Catastrophism.
Robert Farrar sent the link to http://siberiantimes.com/science/casestudy/news/n0434-new-mass-grave-of-... .... the bones of eleven mammoths and one woolly rhinoceros were found near the Ob river in western Siberia - dating between 10,000 and 30,000 years ago (a provisional estimate as C14 has not been done). For years people have been taking bones from the deposit as a souvenir and not a single tusk has remained. Four other mass graves of mammoth are known in Siberia and explanations on how they came about are trite.
At www.catastrophist.org/home/fire-planet/ ... Han Kloosterman has an interesting correspondence with Derek Age. Kloosterman begins by quoting Ager's book, The Nature of the Stratigraphical Record, Harford Press:1973 where he reports on chalk depressions in the southern counties of England, such as the Devil's Punchbowl near Brighton. Chalk run off from the process of making the depressions is rich in snails, and there is evidence of a charcoal layer. Kloosterman's point is that Ager preferred a uniformitarian explanation in preference to a catastrophic one.
