1. Neocatastrophism? [Journals] [Catastrophist Geology]
... .) . Derek V. Ager of Swansea University College, UK, has been so kind to check the palaeontological terms and names. Abstract The acceptance of faunal discontinuities in the history of the Earth has lately been, somewhat ... the sum of formations or systems would always add up to a category of a higher order.

2. Challenges to Evolutionary Gradualism [Books]
... . In contrast to Velikovsky, Schindewolf could not be accused of lacking the credentials needed to put forward theories concerning the evolution of life on Earth. He was professor of palaeontology at Tubingen University from the end of World War II until his death and made extensive field investigations of the Permian-Triassic boundary, particularly in the Salt Range of Pakistan [ ... Chao, Robert Dietz and Eugene Shoemaker, that, in general, explosion craters and crypto-explosion structures had an impact origin [2 ,8 ,9 ]. Meanwhile, palaeontologists had continued to dig, without finding much positive evidence of gradual transitions. However, trapped by the association which had been established between Darwinism and gradualism, and Thomas ...

Chap 5: I | II | III | IIII | PART IV : Appendixes I | II | III | IV | Acknowledgements | Notes And References | CHAPTER 2: Palaeontology and Evolution The study of fossils throughout geological time shows: (a ) That life began with simple, primitive forms, which were replaced by more complicated and specialized ... older than the upper, the fossils contained in the former represent the remains of past living creatures that lived before those found in the latter. Thus, theoretically, the palaeontologist may read in the successive rock layers the record of the successive past living forms throughout geological time and form an idea as to how life has evolved. In practice ...
4. Nemesis for Evolutionary Gradualism? [Books]
... rather than one involving vulcanism [13,93]. Similarly, Finn Surlyk of the Geological Survey of Greenland and Marianne Bagge Johansen of the Institute of Historical Geology and Palaeontology in Copenhagen concluded from their studies that brachiopod extinctions in the Denmark area had occurred very suddenly at the end of the Cretaceous Period [94,95]. In ... biosphere) James Lovelock [8 ]; and physicist Richard Muller, a colleague and ex-student of Luis Alvarez at Berkeley . Initially there were just a few palaeontologists, such as David Raup [3 ,15], Dale Russell  and Digby McLaren [7 ], who were prepared to accept the impact hypothesis ...

If this is so (and Gallant's evidence cannot simply be dismissed or explained away by any unbiased reader), geophysicists, oceanographers, geologists, palaeontologists, archaeologists-and, indeed, all scientific specialists concerned with Earth-history-will have to look again critically at some of their basic conceptions, established long since on the assumption (for ...
6. Catastrophism and Evolution [Journals] [SIS Review]
... vacant ecological niches. Astronomical evidence suggests that at least some mass extinctions are likely to have resulted from the impacts of comets or asteroids upon the Earth, while geological and palaeontological evidence is consistent with the extinctions at the end of the Cretaceous Period and the Eocene Epoch having had such a cause. The Earth and its surroundings Our particular corner ... possibly products of Earth-comet collisions *. Furthermore, an earlier collision might have destroyed the dinosaurs at the end of the Cretaceous Period . The palaeontologist, M. W. de Laubenfels, had previously suggested that the dinosaur extinction might have been caused by a giant meteorite impact . The engineer, ...
7. Controversy: Catastrophism and Evolution, The Ongoing Debate, by Trevor Palmer (Review) [Journals] [SIS Review]
... process, depending on one's evolutionary beliefs. In the societary hierarchy, mass extinctions (biotic crises) are seen as fast or slow events, depending how one interprets the palaeontological evidence. The point is that the catastrophism-gradualism debate is couched in different terms for individual species (speciation events) and for the entire biosphere (mass extinctions) but ... may arise through an increase in the extinction rate, which is what the fossil record suggests happens, but a decrease in the speciation rate would have the same effect. Palaeontologists recognise that, at times in Earth history, global biodiversity has fallen far enough and fast enough to call for the name mass extinction'. Five major episodes of ...
8. Extinction And Survival [Books]
... would be not the `fittest', but the `lucky'. For them, the problem was one of ability to adapt themselves to the new environmental conditions. Palaeontological stratigraphy shows that even these`lucky ones' were generally not able to adapt themselves, and that they died out more or less rapidly. It was not a ... one assemblage of organic remains to another, in which frequently nearly all species, and a large part of the genera, are different. ' But', proclaim orthodox palaeontologists and geologists, `given time, the missing links will be found. ' What Lyell wrote in 1830-3 is still true todayl 2. Two periods are outstanding in ...
