Question: how long ago did dinosurs live

Sam Tazzyman answered on 23 Jun 2011:

Mostly they went extinct 65 million years ago (65,000,000 years – for a comparison, humans have only been around 200,000 years, or about 3% of the time since the dinosaurs). But birds evolved from them, so in a way they’re still around, just nowadays in the form of a sparrow, not a Tyrannosaurus (good for us!).
