... 13.5 .82, p. 419 New Scientist presented a straightforward report upon some work on the Mississippi alligator, in which it had been found that the sex of the developing young is determined by the temperature at which the eggs are incubated. Corriere del Ticino, however, theorizing by analogy, postulated that the death of the dinosaurs could have been caused by slight, non-catastrophic temperature variations producing a unisexual generation incapable of further breeding. This is really wild grasping at straws. Firstly, the dinosaurs were an advanced, warm-blooded group, and would likely have incubated their eggs at a constant temperature (unlike the alligator which leaves its eggs) and to have had genetic ...
112. The Paleo-Saturnian System [Journals] [Aeon]
... of events, utterly unpredictable and quite unrepeatable." [18] It need not even be mentioned how crucial it was that Alvarez's meteor happened to be just the right size, hitting at just the right speed, etc., for it to eliminate 90 percent of Earth's fauna while leaving the mammals intact without a trace of the nasty dinosaurs who had kept us scurrying on the night-time forest floor for eons. Thus, in light of all the above, I believe the Saturn theory needs to take into account just how fragile life- especially human life- really is. We're not here talking about a nearby supernova, or a planet that happened to come a little too ...

... evolution among survivors. Among animals which have obviously gone through a bottleneck in their evolution is, of course, Homo sapiens. Chinese Snapshots of Evolution (New Scientist, 21.5 .05, pp. 40-46) The rock formation in Yixian, China, is proving to be a window on the evolution of birds and other small dinosaurs. The area appears to have been covered in freshwater lakes 125 million years ago, with nearby volcanoes which periodically erupted, killing animals and preserving them under layers of ash. Alternating layers of lake sediment and ash have helped preserve fossils in different ways, allowing scientists to see much minute detail, which might ordinarily have been lost. ...

... , then all sedimentary rocks formed in fish filled waters would also be filled with fish in the very same manner as the Old Red Sandstone. But this is not the case in any manner at all. For example, Willy Ley describes how fossil fish were probably deposited rapidly in sediments in Germany by a catastrophe during the age of the dinosaurs. "Every once in a while, possibly as the result of a submarine earthquake, the sea washed across the coral reef, and the wave carried sea life with it, . . . a swarm of small leptolepis fishes . . . . The leptolepis fish usually have the positions of fish which, frantically trying to reach water ...

... giving a balanced view including that of the skeptics who believe the evidence is explicable in terms of normal volcanic activity and plate collisions. Popular Science gives Hildebrand and Boynton's catastrophist view the nod, citing impact-wave deposits - great heaps of coarse rock deposited in Mexico, the Caribbean islands and along the US coast from Texas to New Jersey. Smallest Dinosaurs source: Daily Telegraph 9.5 .90 Prof Robert Bakker of the University of Colorado has unearthed the bones of the smallest dinosaurs in history, animals no more than 2-3 feet high. They are very similar to mini-dinosaurs found in Dorset in 1834 and are proof for Bakker that these creatures were the survivors, 130 million years ago ...
116. On Saturn And The Flood [Journals] [Kronos]
... common with the earlier forms they replaced.(15) Thus, over the past two or three decades, many geologists and paleontologists have found themselves increasingly drawn to the view that the observed abrupt changes in the biosphere, such as that which marked the end of the Mesozoic and is thought to have brought with it the extinction of the dinosaurs,(16) among other animal groups, could best be explained by the exposure of the then living organisms to massive doses of radiation coming from a nearby supernova. The radiation would annihilate many species, especially those whose representatives, whether because of their large size or for other reasons, were unable to shield themselves from the powerful ...

... wish to take on material from outside their own fields are especially at risk from flawed popular accounts. To underline the warning, here are a few notable examples from Asimov's other work. In Please Explain, Asimov states that: "H . K. Erben of Bonn University... pointed out that in the last stages of the dinosaurs' existence, they were laying eggs with extremely thick shells.... Baby dinosaurs had difficulty battering their way out.... Between this and other similar mutations, the whole group of magnificent creatures died out." [47] One might be forgiven for wondering how such a mutation spreads through the population! Compare ...

... climate for the epoch when the plenum declines; the extinctions noted may be related to this phenomenon. The later extraterrestrial discharges of water collected into deep pools rather than in shallow marshes, once the ocean basins were sculpted. The end of the Triassic sees further mass extinctions. So does the cretaceous, which concludes with the disappearance of the dinosaurs and other groups. In the Cenozoic, "speciation was rampant, as a multitude of niches was invaded in the replacement of extinct reptiles" (Stanley). An average species of late Cenozoic mammal survived one to two million years without transitional forms. With this average, it seems impossible to account for changes from primitive forms to ...

... geologic record in Chapter VII of Ragnarok: "The Earth Struck By Comets Many Times".(21) Similarly, in "Cometary Collisions and Geological Periods," a letter published in Nature (1973), Harold C. Urey said: "it does seem possible and even probable that a comet collision with the Earth destroyed the dinosaurs and initiated the Tertiary division of geologic time."(22) And in The Hot Blooded Dinosaurs (1976), Adrian J. Desmond makes this interesting observation: "According to the latter-day catastrophists, the dinosaurs exited with the most spectacular bang since Creation, and, the geologist's lingering aversion to cataclysms notwithstanding, it is becoming ...

... comes not from the world but from us, which has to make us suspect that it is projected by us onto the world because that is desperately how we want to see it. When we contend that the cosmos was hot balls of fire and explosion but now it is settling down to a perfect clockwork, that life was reptiles and dinosaurs and giant animals but now it is settling down, that the earth experienced impacts and ice ages and vast extinctions but now it is settling down, we can see that this is merely a myth which we have created and which we then blindly extend to civilization (people were savage and wild and primitive but now they are settling down ...
