T. rex and the Crater of Doom

T. rex and the Crater of Doom PDF Author: Walter Alvarez
Publisher: Princeton University Press
ISBN: 0691169667
Category : Science
Languages : en
Pages : 208

Book Description
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.

The Great Dinosaur Extinction Controversy

The Great Dinosaur Extinction Controversy PDF Author: Charles Officer
Publisher: Addison Wesley Publishing Company
ISBN:
Category : Nature
Languages : en
Pages : 232

Book Description
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.

Why Dinosaurs Matter PDF Author: Kenneth Lacovara
Publisher: Simon and Schuster
ISBN: 1501120107
Category : Nature
Languages : en
Pages : 192

Book Description
What can long-dead dinosaurs teach us about our future? Plenty, according to paleontologist Kenneth Lacovara, who has discovered some of the largest creatures to ever walk the Earth. By tapping into the ubiquitous wonder that dinosaurs inspire, Lacovara weaves together the stories of our geological awakening, of humanity’s epic struggle to understand the nature of deep time, the meaning of fossils, and our own place on the vast and bountiful tree of life. Go on a journey––back to when dinosaurs ruled the Earth––to discover how dinosaurs achieved feats unparalleled by any other group of animals. Learn the secrets of how paleontologists find fossils, and explore quirky, but profound questions, such as: Is a penguin a dinosaur? And, how are the tiny arms of T. rex the key to its power and ferocity? In this revealing book, Lacovara offers the latest ideas about the shocking and calamitous death of the dinosaurs and ties their vulnerabilities to our own. Why Dinosaurs Matter is compelling and engaging—a great reminder that our place on this planet is both precarious and potentially fleeting. “As we move into an uncertain environmental future, it has never been more important to understand the past.”
