Why did dinosaurs become extinct?

The dinosaurs died out 66 million years ago, which suggests a sudden catastrophic event sealed their fate. It is presumed that something must have caused unfavourable changes to the environment and it must have occurred more quickly than dinosaurs could adapt. The cause of this catastrophic event is debatable. Some evidence points towards an asteroid impact. Volcanic eruptions that caused large-scale climate change may also have been involved, as well as more gradual changes to Earth's climate that happened over millions of years.
