Product Description
What killed the dinosaurs? For more than a century, this question has been one of the greatest unsolved mysteries in science. But, in 1980, Nobel Prize-winning physicist Luis Alvarez and his son, Walter, proposed a radical answer: 65 million years ago an asteroid or comet as big as Mt. Everest slammed into the earth, raising a dust cloud vast enough to cause mass extinction. A revolutionary idea that challenged the ice-age extinction theory, the asteroid-impact theory was scorned and derided by the science community. But after years of bitter debate and intense research, an astonishing discovery was made-an immense impact crater in the Yucatn Peninsula that was identified as Ground Zero. The Alvarezes had their proof. A dramatic scientific detective story, INight Comes to the Cretaceous/I is a brilliant example of science at work-in the trenches, complete with passionate struggles and occasional victories.

 Lack of objectivity. An embarassingly one-sided shill. March 11, 2005
Kersi Von Zerububbel (San Diego, CA USA)
7 out of 12 found this review helpful
I was hoping for a balanced analysis supporting the dinosaur extinctions via an asteroid doing a number on mother earth. Instead I got a steady dose of denunciations towards anyone who disagreed with the asteroid theory. The tone is palatable at first but after a while repeating the same canard over and over does tend to get tiresome. Around page 170 or so I realized that I was reading an apologist for the asteroid theory. br / br /I was very disappointed that other theories were given short shrift and at times almost mocked. This is a so so book about dinosaur extinctions but I am waiting for a truly meaty and balanced book.
A very clear account, but of questionable objectivity.... February 8, 2005

I did't find this book to be a particularly good review of the dinosaurs-vs-meteorite controversy. The narrative is clear and captivating, and accounts of the several open (or closed!) disputes, rooted in disparate fields of Earth sciences, is made accessible to the layreader or those with just a modest background in natural sciences. Nevertheless, Powell holds a one-sided approach right from the beginning, pointlessly crusading against some supposedly general backward attitude in geologists and paleontologists that actually never was there, except for a very few unfortunate cases. Everyone now agrees on evidence for a massive extraterrestrial impact dated around 65 million years ago, but the main issue is presently whether that was the ultimate cause of the mass extinction or other earth-bound factors and feedbacks played a role in driving interactions between physical environment and the biosphere toward a mass extinction. Powell leaves no room for such developments. br / In particular, I'd have two specific objections to specific cases presented in the book: 1)On pages 172-174 taxonomic analysis of dinosaur diversity in the highest stratigraphic stages of the Cretaceous in Montana is reported as evidence in favour of a sudden crisis of the original ecosystem. Pete Sheehan and co-workers carried on their studies at the taxonomic rank of families, which resulted numerically stable with time approaching the K-T boundary. Only, John Horner recently reviewed their work at a species level, likely to be statistically and biologically more reliable indicator of biodiversity, and found out a steady decrease of dinosaur types through time. Such reconsideration of Sheehan's research thus reverses evidence against the impact hypothesis! 2) The section "Did impact cause all extinctions?" introduces the final part of the book which has absolutely nothing to do with the K-T event per se, and presents us with Raup's "impact-kill curve" which was originally just an interesting exercise in statistics, but lacking a solid connection with the actual geo-paleontological database of major mass extinctions (let alone minor ones..) and thus oversimplifies the subject. Yet the author all too enthousiastically takes sides with the "impactors" and loses objectivity, even falling in contradiction (Page 192:"Not enough firm evidence is available to corroborate the claim that impact is responsible for any other mass extinction boundary than the K-T event..." Page 196:"..how are we to escape the conclusion that not just in theory, but in practice, impact has caused many extinctions?") br /More poignantly however, scientific arguments and debates against the "impact hypothesis" haven't been introduced thoroughly enough but too quickly glossed over, although numerous in the recent scientific literature... br /Without deceiving myself of having read a downright objective account, I'm afraid this is the best available book about the (still ongoing...) debate, together with J.D.Archibald's "Dinosaur Extinction and the End of an Era: What the Fossils Say", which is possibly far more objective though... br /
 A great description of science from the inside August 6, 2004

This is one of the best science books I have ever read, and a great description of how science works from the inside. Scientists aren't impartial godlike figures, they're human beings just like the rest of us.This book details how a geologist, by bringing his father an interesting rock--a polished specimen that included the K-T boundary layer, deposited when the dinosaurs all vanished--started a controversy that revolutionized and redefined the entire field of earth sciences. Personally, I love it when that happens, that's how science is supposed to work, but people who have built their entire careers on the old view of things can have a very difficult time accepting a new paradigm, and will go to ludicrous extremes to defend the old one to their dying breath. The impact theory of extinctions is one of the scariest concepts I have ever come across, but I am a lot happier knowing how things really work. This is an utterly fascinating read, and I can't recommend it strongly enough. To anyone interested in geology, astronomy, dinosaurs, (who isn't interested in dinosaurs??), or the workings of science, I can only say---READ THIS BOOK!!!!
 Night Comes to the Cretaceous August 1, 2003

All in all, James Lawrence Powell did a superb job in writing this book. He is highly opinionated and interprets data in a manner to support his fundamental belief (that an asteroid caused the KT extinctions).brI advise readers to get a balanced view by also reading The Great Dinosaur Extinction Controvery by Charles Officer and Jack Page. I felt that Powell covered the topic very thoroughly and provided historical context to help the novice extinctions reader. I felt that the book was very weak in dicussing the paleontological aspects of the extinction. Next revision perhaps.
How Scientific Revolutions Actually Happen June 13, 2003
David Morrison (San Jose CA USA)
3 out of 4 found this review helpful
One of the great scientific revolutions of our times has been the recognition that the biological evolution of Earth is influenced random impacts by comets and asteroids. When this concept was put forward in 1980, it was radical; today it is the accepted wisdom in paleontology, geology, and evolutionary biology. Jim Powell tells a fascinating story of the evidence for this transformation and of the scientists who have been protgonists in the struggle to understand this evidence and integrate it into our broader undestanding of our planet. This is one of the best books ever written to trace the history of a scientific controversy and of the people involved, warts and all.
