Why did dinosaurs and other similar creatures become extinct?

What wiped them all out? Was there a primitive nuclear war or something?

I don't think there is really a way to know. If they were exotherms, they wouldn't have survived the last ice age. But, if that were true, why are alligators and Komodo dragons still around?

@MySecretIdentity1 I didn't realise alligators were prehistoric creatures. I see what you mean about Komodo dragons though.

@Crazychick Some scientists say alligators and some sharks have been around millions of years without much change.

@MySecretIdentity1 Maybe they have. I don't know for sure so I'm not going to argue about it.
