Description: What killed the dinosaurs? For many years, this question has been one of the greatest unsolved mysteries in science. Then in 1980, a radical theory was proposed: 65 million years ago, an asteroid or comet as big as Mt. Everest, traveling at 100,000 miles per hour, struck the earth, throwing up a dust cloud that darkened the sky, caused the temperature to plummet, and killed the dinosaurs and 70 percent of all other species.

Night Comes to the Cretaceous is the first comprehensive and objective account of how this fantastic theory changed the course of science. The author, Director of the Los Angeles County Museum of Natural History tells the dramatic story of how Nobel Prize-winning physicist Luis Alvarez and his son Walter stumbled onto evidence suggesting that a single random event caused the extinction of the dinosaurs - a claim many scientists found unbelievable.

After years of bitter debate and intense research, an astonishing discovery was made - an immense impact crater buried deep in the Yucatan Peninsula in Mexico that was identified as Ground Zero. The unbelievable appeared to be true.
