... C-T iridium layer. Even then another school of thought voted for massive endogenous volcanism as indicated by the Deccan traps. Only after evidence was discovered in Yucatan of a crater large enough and from the right time period could it be said that modern catastrophism had truly arrived, although by no means all the establishment accepts the impact theory for the extinction of the dinosaurs. However, in the course of 14 years books on the dinosaurs at the Natural History Museum have drastically changed from declaring that their extinction was not sudden to an impact scenario. Catastrophism, it seems, is indeed alive and well again. Bob Porter had been considering The Egyptian Third Intermediate Period. This is a ...
... perennial snow. The deserts of Arabia, Sahara and Gobi were covered by forests and pastures, and man's neolithic relics and rock drawing show how recently these wastes were richly watered and were inhabited. The remains of whales are found on mountains; fig trees and corals are found in polar regions and signs of ice in Equatorial Africa. Widespread extinctions in America occurred virtually within the last few thousand years. ' "I gave the history of the theory of catastrophism versus the theory of gradualism and evolution. The Agassiz theory of the ice ages was originally also a catastrophic theory. Agassiz spoke of the sudden arrival of the ice cover seizing the mammoths of Siberia. The north Siberian ...
493. Thoth Vol I, No. 16: June 15, 1997 [Journals] [Thoth]
... story. He returned with bad news: the reports were correct. Everyone now accepts the existence of meteorites but the confirmation came too late to save hundreds of specimens from being unceremoniously thrown out of museums as "superstitious artefacts". The now widely-accepted theory that a hugh meteor struck the Earth 65 million years ago, pushing the dinosaurs into extinction, also came in for a least as much abuse as the idea of micro-comets when it was originally proposed. When the late Nobel Prize-winning physicist Luis Alvarez and his team first published their evidence for the giant impact in 1980, one authority described it as "a nutty theory of pseudoscientists posing as paleontologists". Today it is the ...
... the island under showers of scoriae and ashes. The affrighted inhabitants had fled for safety to the neighbouring isle of Fuertaventura, and when they returned they found a soil far richer than when they had left it, and were able to cultivate the vine, which previously had not taken favourably to the soil. 82.. A number of extinct craters or craters in a state of solfatara gradually form lakes, to which the formation of the crater, consisting of a circular or oblong elliptical cavity surrounded by the steep walls, offers favourable circumstances, like a saucer or cup whose lips collect and pour down the rain-water that falls. Many of these crateral lakes are very deep and ...
... the brontosaurus, which lived on land, though doubtless near the water; the pterodactyl, which was even able to rise in the air; and many others. With them lived the arch-bird, archaeopteryx. There were also great reefs of corals, and immense multitudes of mussels, snails, ammonites, belemnites, etc. When the dramatic extinction of the saurians eventually came about, all these were embedded in a fine-grained sediment which has preserved them to perfection. The reason for this extinction was, of course, the catastrophic end of the Jurassic period caused by the eventual breaking loose of the Mesozoic satellite from its anchorage bollard, and its advance eastwards. The tide hill, ...
496. Catastrophism and the Compulsion to Meaning [Journals] [Kronos]
... to the beginning. But these difficulties are minor compared to the philosophical consequences. In reconstructing catastrophic events the most important "measuring instruments" by which we "observe" planetary movements are human accounts. Already as collected in Worlds in Collision they range from mathematical registrations preserved on cuneiform tablets to fragments of folklore relayed by anthropologists from tribes approaching extinction. The overwhelming mass of these accounts is essentially conditioned by what we call "mythical thinking". As stated earlier, it seems characteristic of this kind of thinking to charge all phenomena with spiritual meaning and to find the symbols of catastrophic experience indispensable for that purpose. If we set out to find meaning in such experience, then ...
497. The Countdown to a New Celestial Hazard [Journals] [Aeon]
... problem has always been where these objects come from; and it was the Irish-Estonian astronomer Opik in the 1960's who first indicated that the Oort cloud was the likely source both of short-period comets and of Earth-crossing (i .e . potentially catastrophic) asteroids. Somewhat later, the American astronomer/geophysicist Urey was to associate short-period comets with mass extinctions and geological boundaries but a more general theory, combining both these proposals, was not obviously excluded. This led two British astronomers, Clube and Napier, to the suggestion that disintegrating large comets were mostly responsible for sustaining both the near-Earth asteroid and short-period comet populations and for controlling most aspects of terrestrial catastrophism (climate, orogeny, geomagnetic ...
498. The Date Of The Loss Of Atlantis (The Atlantis Myth) [Books]
... other words, the great Klimasturz. Anthropologists and pre-historians attribute to the find-places of these tribes an age between 20,000 and 10,000 BC. How much support these figures gain from Hoerbiger's theory of the conjunction and capture cataclysms and the migratory movements set off by them is quite evident. Another interesting date of a culture doomed to extinction by a sudden terrestrial convulsion is supplied by the following. To the south of Mexico City there is an extensive lava-field, called the Pedregal, which is considered by geologists to have been ejected by volcanoes in the Ajusco Mountains in a short, sharp eruption `between 7,000 and 13,000 years ago. A step-pyramid of ...
499. Forum [Journals] [SIS Review]
... Napier use evidence from vulcanism to demonstrate atmospheric cooling caused by stratospheric ejecta; they state that impacts trigger vulcanism (as did Velikovsky) citing in particular the Deccan Traps eruptions at the close of the Cretaceous period. Maclean in America [28] and Courtillot in Europe [29] have suggested that all the K-T boundary effects (notably dinosaur extinction and iridium enhancement) may be accounted for by vulcanism alone; and that, moreover, the hot plume required to generate the volcanic effects is millions of years in the making, necessarily decoupling the Deccan event from any contemporary impact cause. They may be right, or they may be just sitting there with Canute. Similarly, when ...
500. Pleiongaea: A Myth for all Seasons [Journals] [Aeon]
... Venus still has a massive atmospheric envelope some 90 times that of Earth while being some 30% closer to the Sun, and, hence, twice the exposure to the T-tauri zephyr. Planetary Nova Students of natural history invariably run into a blank wall in the perennial quest for a primal cause of geological and paleontological events. The upheavals and extinctions, under equally bizarre circumstances, have sparked many hypotheses to account for the five major catastrophic changes closing one geological period and opening another. (Of course, innumerable minor events in a wide variety of localities complicate the history of the Earth.) It is thought that during the mid-Mesozoic era, a mere 150 million years ago, ...
