When did the dinosaurs get wiped out?

65 million years ago, most of the dinosaurs were killed by a large asteroid, which landed in the Yucatan Peninsula in east Mexico where a very, very wide and deep crater is there today.

The comet killed the dinosaurs by shooting up a cloud of ash which blocked out the sun over most of the Earth and started an ice age which killed them because they couldn't survive the freezing temperatures.

However, some animals survived by exploding into more hairy or insulated-skinned animals such as the mammoth (now extinct) well that was pointless wasn't it!

The crocodiles and alligators are examples of dinosaurs which have survived the ice age the question was when did the dinosaurs get wiped out and I am sorry that I kept going on and on I realize I made a mistake and I am sorry.
