1. Controversy: Catastrophism and Evolution, The Ongoing Debate, by Trevor Palmer (Review) [SIS C&C Review $]
... of extraterrestrial processes (particularly asteroidal and cometary impacts) has come 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 of extraterrestrial events in Earth history and in the history of bodies ... or sudden events? what causes mass extinctions? Do mass extinctions take place slowly or swiftly? To answer this question, it is important to understand the nature of a mass extinction. A mass extinction is the net loss of unusually many species. It may arise through an increase in the extinction rate, which is what the fossil record suggests happens, ... in which tropical marine biotas, including stenothermal calcareous algae, declined greatly 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 the sea, the extinction of planktonic foraminiferal species spanned 300, ...

5. For the Record. . . [Kronos $]
... natural selection of small chance variations is the central fact in evolution.... Rapid adaptation is metamorphosis. By rapid adaptation to new environments some animals survived the repeated great extinctions that have periodically depopulated our globe. New species resulted. So it is that fossils found at the end of one epoch differ profoundly from those found at the beginning of the ... to explain the history of the earth. They agree, however, that these processes must have varied greatly in rate." Thus, Newell attempted to deny catastrophic authenticity regarding extinction and evolution by propounding the concept of "gradual catastrophes" or "varying uniformitarianism," once again demonstrating how science can squeeze or stretch pre-conceived notions into a procrustean bed of ... own design. Newell could not accept violent and sudden global upheaval, whether terrestrially or extraterrestrially induced, as an extinctive mechanism, even though he was acutely aware of certain problems involving the subject of extinction. "It is striking that times of widespread extinction generally affected many quite unrelated groups in separate habitats. The parallelism of extinction between some of the aquatic ...

... little affected by whatever happened at the Cretaceous-Tertiary interface. Furthermore, many groups that were extinguished were already well into a decline. Some geologists insist that some of the supposedly synchronous extinctions were probably separated by several hundred thousand years; viz., plankton and dinosaurs. The vaunted iridium anomaly in deep-sea cores is spread through a considerable thickness of sediment. Even ... environment acting upon kerogenand pyrite-rich clay. In short, some geologists at least do not find the asteroid hypothesis compelling at the moment.

Cretaceous Catastrophe- 1 source: Nature 324, 13.11.86, p.112 There is now corroborative evidence of widespread extinctions of land plants at the Cretaceous-Tertiary boundary, something that has generally been overlooked in the obsession with dinosaurs and marine life.

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.

... ," one can expect the Earth to exhibit hills and mountains, as of iron ore and erratic isolated hills, which are then surficial mascons.

The anomalous magnetized rocks are about 1100 feet deep and assigned to Late Cretaceous which makes it, too, a candidate for extincting dinosaurs and decimating the biosphere.
