Sixty-five million years ago a gigantic comet or asteroid as big as Mount slammed into the Yucatan Peninsula, creating an explosion on impact equivalent to the detonation of a hundred million bombs. It produced a cloud of roiling debris that blackened the sky for months as well as other geologic disasters--and triggered the demise of Tyrannosaurus rex. We know what happened largely because Walter Alvarez--synthesizing the findings of experts from a variety of scientific fields--has written a gripping story of the decades-long search for the cause of the dinosaurs' extinction.
