Walter Alvarez, a geologist at the University of California at Berkeley, and one of the four scientists who present this theory on the mystery, tells the story in a clear narrative that contains a wealth of scientific material. The book does require an investment of attention, but the presentation is quite readable and the story itself is fascinating.

Review
Appealing and accessible, an excellent introduction to the subject.
(Kirkus Review )

A fascinating proof of a once ridiculed theory. In fitting together the puzzle of dino demise, Alvarez excitingly shapes the story for the widest audience.

[D]eft and readable . . . T. rex and the Crater of Doom gets the facts across in a lighthearted, almost playful manner. But it's also solid science, a clear and efficient exposition that conveys plenty of cogent detail while keeping an eye on the subtle interplay of thought, action, and personality that makes scientific research such arresting human behavior. . . . [An] estimable account from the world's leading authority on death from above.
(Timothy Ferris New York Times Book Review )

A geologist (who happens to be a kind of working philosopher) gives a deft, readable explanation of the extinction of the dinosaurs.
(New York Times Book Review )

A nicely told and well-written tale of scientific discovery.
(Library Journal )

The book is very well written and so engrossing that a reader with little or no background in the earth's geologic history will enjoy an easy and vastly entertaining summary of how we came to our present understanding of the past. It is a wonderful adventure in science.
(Dale Russell The Los Angeles Times Book Review )

Alvarez's book recounts this scientific detective story in an authoritative yet consistently engaging manner. Once considered absurd, the idea that extraterrestrial factors were involved in some of the great crises in the history of life has become widely accepted.

(Charles Petit San Francisco Chronicle )

This personal account of the search for a geological Excalibur makes fascinating reading. . . . [It] reads like Arthurian legend, full of temptations which lead the hero astray and distract him and his followers from the true path.
(Douglas Palmer New Scientist )

An unfolding story told by its leading protagonist. . . . Very clearly and entertainingly written, and illustrated with fascinating colour plates, it is accessible even to nonspecialists.
