One of the great mysteries is what happened to the dinosaurs, and it has taken great detective work to give us an answer. In T. Rex and the Crater of Doom, some brilliant, not to mention determined, scientists roam the world and seek out the clues. What they conclude is that the earth withstood a colossal impact with a meteor or perhaps a comet 65 million years ago. The resulting cataclysm destroyed half the life on the planet.

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.

When Nobel prize-winning physicist Louis Alvarez and his geophysicist son Walter announced that they had discovered evidence of a giant meteor that slammed into Earth 65 million years ago, causing the extinction of the dinosaurs, they were met with much fanfare from the popular press and skepticism from the scientific community. The Alvarezes were vindicated in 1991 when a huge impact crater was discovered on the Yucatan Peninsula, and the possible connection with dinosaur extinction is becoming more widely accepted. After a vivid description imagining the global devastation that would be caused by such an impact, Alvarez offers a first-person account of the discovery. It's a nicely told and well-written tale of scientific discovery, and though he occasionally comes across as a bit smug, Alvarez is quite generous in crediting objectors for helping show the direction to improve and refine the theory with further research. This informal, readable book is appropriate for high school readers on up, and the subject has strong popular appeal.?Amy Brunvand, Univ. of Utah Lib., Salt Lake City
