Question: Is it true the dinosaurs killed themselves by farting?

Iain Bethune answered on 24 Jun 2015:

Don’t think so! The dinosaurs were wiped out by a massive comet or asteroid which hit the earth in what is now the Gulf of Mexico about 66 million years ago. About 75% of all the animals and plants died out as a result of this impact, and the resulting dust cloud that blocked out sunlight for years afterwards.
