Synopsis The Great Dinosaur Extinction Controversy by : Charles Officer
In 1980 Nobel Laureate Luis Alvarez announced his theory of the dinosaurs final demise: a gigantic meteorite crashed into the earth and raised a cloud of dust that caused darkness for years, suppressing photosynthesis, which impeded plant growth, and eventually starved the dinosaurs. This idea exploded into common awareness with almost unprecedented speed, and was instantly embraced by the media and the public. Almost without question, it quickly became the hottest scientific "fact". Unfortunately for Alvarez, many in the scientific community did to support this theory, and in fact later research showed the impossibility of such an idea. The Great Dinosaur Extinction Controversy chronicles the fantastic story of how this hypothesis became so widespread, the way it became "common knowledge" - from the pages of Science to The New York Times to Parade Magazine, the controversy it caused, and the ample scientific research that proves the theory wrong. Officer and Page also present an attractive and carefully investigated alternative explanation for the mass extinctions that occurred at the end of the Cretaceous period. Through this account they show the ways that sound science should be performed and the findings transmitted.

Synopsis The Great Dinosaur Controversy by : Keith Parsons
A historical review of the most important scientific controversies that have shaped our knowledge of dinosaurs since the discovery of important fossils in the 1820s. In The Great Dinosaur Controversy: A Guide to the Debates, the major scientific disputes that have contributed to the understanding of dinosaurs come to light. Each chapter presents a major controversy then ponders the lessons learned and their impact on the scientific field. Colorful characters such as "anti-evolutionist" Robert Owen, "Darwin's bulldog," T.H. Huxley, and "dinosaur heretic" Robert Bakker, enliven the debates, which range from the origin of dinosaurs and their posture to their evolution or retrogression and whether they were warm- or cold-blooded. Two of the most recent debates concern how dinosaurs became extinct and whether or not birds are their descendents.

Synopsis Extinction and Radiation by : J. David Archibald
This study identifies the fall of dinosaurs as the factor that allowed mammals to evolve into the dominant tetrapod form. It refutes the single-cause impact theory for dinosaur extinction and demonstrates that multiple factors--massive volcanic eruptions, loss of shallow seas, and extraterrestrial impact--likely led to their demise. While their avian relatives ultimately survived and thrived, terrestrial dinosaurs did not. Taking their place as the dominant land and sea tetrapods were mammals, whose radiation was explosive following nonavian dinosaur extinction. The author argues that because of dinosaurs, Mesozoic mammals changed relatively slowly for 145 million years compared to the prodigious Cenozoic radiation that followed. Finally out from under the shadow of the giant reptiles, Cenozoic mammals evolved into the forms we recognize today in a mere ten million years after dinosaur extinction.

Synopsis T. rex and the Crater of Doom by : Walter Alvarez
Sixty-five million years ago, a comet or asteroid larger than Mount Everest slammed into the Earth, inducing an explosion equivalent to the detonation of a hundred million hydrogen bombs. Vaporized detritus blasted through the atmosphere upon impact, falling back to Earth around the globe. Disastrous environmental consequences ensued: a giant tsunami, continent-scale wildfires, darkness, and cold, followed by sweltering greenhouse heat. When conditions returned to normal, half the plant and animal genera on Earth had perished. This horrific chain of events is now widely accepted as the solution to a great scientific mystery: what caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth's geological history.

Synopsis Night Comes to the Cretaceous by : James Lawrence Powell
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 Yucatan Peninsula that was identified as Ground Zero. The Alvarezes had their proof. A dramatic scientific detective story, Night Comes to the Cretaceous is a brilliant example of science at work-in the trenches, complete with passionate struggles and occasional victories. "
