Bang, you're dead

摘要

Our author, James Lawrence Powell, is in absolutely no doubt that 65 million years ago a large asteroid hit the Earth, leading to the mass extinction of species. Indeed, as early as the fourth sentence of Night Comes to the Cretaceous he makes his belief clear: "At last the great mystery [of what killed the dinosaurs] has been solved." This is a pity, because such conviction makes the book less an unbiased record of a major scientific debate and more an exercise in advocacy.
