What happened to the dinosaurs and how did they die?

The instantaneous devastation in the immediate vicinity and the widespread secondary effects of an asteroid impact were considered to be why the dinosaurs died out so suddenly. Asteroids are large, rocky bodies that orbit the Sun. They range from a few to hundreds of metres in diameter.
