... to prominence as a potent evolutionary driving force. Sudden catastrophic events, such as meteor showers, may cause mass extinctions followed by rapid bursts of new species. To argue his case, Palmer starts the book by introducing the role ... and reef communities were decimated [7 , 8]. The detailed pattern of late Cretaceous extinctions suggests a gradual extinction-rate increase for many groups of organisms, followed by a catastrophe lasting a few tens of thousands of years. In ... catastrophic impacts. At least six cases of features generally considered diagnostic of large impacts are known at or close to extinction-event boundaries, so the Shiva Hypothesis adds weight to Palmer's argument. However a radically different reading of the evidence is ...
2. Radiocarbon Dating The Extinction [Journals] [Velikovskian]
... From: The Velikovskian Vol 3 No 2&3 (1997) Home | Issue Contents Radiocarbon Dating The Extinction Charles Ginenthal Radiocarbon dating is the final support, and only support for the contention of the age of the extinction. As Haynes says, "According to radiocarbon dates, a proboscidean crisis occurred 10,000 to 12, ... survived best. In terms of the Seuss Effect and carbon 14 dating, this south to north extinction effect is well corroborated. Haynes also speaks of a "west-to-east" extinction113 which suggests that the geographical pole was not in its present place which skewered the growing seasons on the globe along different latitudes. Naturally, there are exceptions to this ...
3. Nemesis for Evolutionary Gradualism? [Books]
... confusion between the Cretaceous and the Cambrian or Carboniferous Periods [3 ,4 ]. The K-T boundary, more than any other between geological periods, is clearly defined throughout the world [5 ]. One likely reason for this is that, at around 65 (or 66) Myr old, it is younger than the other major mass extinction horizons identified by Norman Newell [6 ], so has had less chance of being affected by any disruptions of the Earth's crust [3 ,7 ]. The K-T boundary in limestone formations is commonly marked by a thin clay layer, just a centimetre or so in thickness [1 ,2 ,5 ,8 ,9 ] ...
4. Towards a New Evolutionary Synthesis [Books]
... all the apparently abrupt changes in the fossil record involved nothing more complicated than size. Although the book was intended to be a `general discussion of evolution', mass extinctions were never called by name, and the topic of extinctions almost totally ignored, more space being given to the subsequent adaptive radiations. Of course, evolution can proceed ... only in seeing macroevolution as a continuation of microevolution, but also in failing to recognise the evolutionary importance of extinctions. He continued: "Some evolutionists have trouble envisioning an extinction-driven trend in the speciational mode. Extinction makes nothing. How can the mere elimination of part of a spectrum of variation among species achieve anything new in evolution? People ...
5. Nemesis for Evolutionary Gradualism? [Journals] [SIS Review]
... by Trevor Palmer Dr Trevor Palmer is Head of the Department of Life Sciences at Trent Polytechnic, Nottingham, and a member of SIS Council. He is author of Understanding Enzymes, now in its second edition, and of about 50 research papers and review articles. Evidence continues to accumulate for extraterrestrial impacts at the Late Cretaceous and other mass extinction horizons. A possible periodicity in mass extinctions has been detected, which may be associated with cometary or other bombardments resulting from the effects of a Solar companion, a tenth planet, movement across the galactic plane, or ejection of core material from large gaseous planets. Following the publication in 1980 of the paper of Luis and Walter Alvarez ...
6. Some Additional References on Mass Extinctions and on Radioactivity (especially K-T) [Journals] [Catastrophist Geology]

From: Catastrophist Geology Year 3 No. 1 (June 1978) Home | Issue Contents Some Additional References on Mass Extinctions and on Radioactivity (especially K-T)Johan B.Kloosterman Selected by Johan B.Kloosterman from several bibliographies, using as criterion only the titles.

7. Times And Dates. Ch.12 The Ruins Of The East (Earth In Upheaval) [Velikovsky] [Velikovsky Earth in Upheaval]
... Gale obtained the same result on Owens Lake in California and also Van Winkle on Abert and Summer lakes in Oregon. Radiocarbon analysis by Libby also indicates that plants associated with extinct animals (mastodons) in Mexico are probably only 3 500 years old. Similar conclusions concerning the late survival of the Pleistocene fauna were drawn by various field workers in ... fields in historical times. The Florida fossil beds at Vero and Melbourne proved-by the artifacts found there together with human bones and the remains of animals, many of which are extinct-that these fossil beds were deposited between 2 000 and 4 000 years ago. As brought out by Godwin, the two irruptions of the sea on English shores also took ...
8. Cataclysmic Evolution. Ch.15 Cataclysmic Evolution (Earth In Upheaval) [Velikovsky] [Velikovsky Earth in Upheaval]
... of competition, but in upheavals against which superior structure is no defence. The observation that healthy species of animals, like mammoths, with no sign of degeneration suddenly became extinct greatly troubled the evolutionists. This fact is unexplainable by natural selection or the principle of competition; not so by the catastrophic intervention of nature. The fact that at ... , in conflict with the idea of slow extinction in natural selection, conforms with the theory of cataclysmic evolution. The enigmatic observation that the larger animals were particularly subject to extinction-the giant mammals that succumbed at the end of the Tertiary, and again in the Pleistocene, as earlier the dinosaurs did-is comprehensible if one thinks of the better chances smaller ...

... how many more there are. It is similar in size and features to Manicouagan crater in Quebec, and dates from 136 Myrs ago, which is the Jurassic/Cretaceous extinction boundary. No high concentrations of the rare earth metals (iridium etc) have been found at/near such large craters, so if they were present they must ... based on the depth of "sediments" at the boundary and immediately below it. The plant "evidence" has had to be revised recently - in favour of the extinction-event hypothesis - see above. Revised Dating source: New Scientist 14.5 .87, p.34 A new technique of dating ancient limestone sediments by comparing the ...
10. The Climate Hypothesis [Journals] [Velikovskian]
... From: The Velikovskian Vol 3 No 2&3 (1997) Home | Issue Contents The Climate Hypothesis Charles Ginenthal The other major theory for the Pleistocene extinction is based on a sudden onset of warm weather, which drastically changed the environment and left the fauna in areas which no longer could support them. Unable to adapt to this rapid, environmental change they simply died out. This theory had been suggested by Alfred Russel Wallace before he opted for the hunting hypothesis as more acceptable. What he originally believed is that the extinction had been brought about by "the great and recent physical [climatic] change known as the Glacial Epoch. '" 1 Krishtalka summarizes this ...
