Why this book?
This is the classic story of the amazing discoveries that led to the hypothesis that a large comet or asteroid impact, 66 million years ago, caused a global catastrophe that wiped out the dinosaurs and most other species of life, as told by the discoverer of the critical evidence. Alvarez is a master storyteller—the book is written along the sensational lines of a great scientific murder mystery, solved by geologic detective work, but also relying on mind-bending serendipity. These discoveries by Alvarez and others marked the beginning of an ongoing revolution in the geological sciences and forced geologists to recognize the critical role played by rare, but devastating, catastrophic events in earth history.

What is this book about?
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.

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?…
