You sound as if you think they all left in a giant spaceship.
You realise many hundreds of thousands of dinosaur species had already gone extinct when the last of them died out?
The last died about 65,000,000 years ago. The end of the Cretaceous period.

Leviathan is correct, the dinosaurs died out about 65 million years ago. However there is quite a bit of speculation that they died as a result of a catastrophic event. A large meteor striking the earth, which put so much dirt, etc into the air that all plant/animal life on earth died from the resulting cold.
