Did Dinosaurs leave Earth? and how advanced could they have been?

Question

In 2 million years humans have attained a fair amount in terms of Science, and yet the Dinosaurs had 60 million years to work with.

So if the Dinosaurs civilisation left Earth in a huge Space Admarda would it not be possible that in the millions of years between their exodus and our rise to dominance, that all evidence of the Dinosaur civilisation would be lost, as would be the case if the human race left Earth in the future and allowed lower native creature to evolve to dominance upon Earth. All evidence of humanity would crumble, rot, weather away and rust into nothing, within 10 million years.

Answer 1

They didn't leave Earth. And there weren't signs of it. If there were they should've put it in the news or something. You have a great imagination!

Answer 2

Uh, LEAVE?

They DIED. (Except some of the smaller ones, whose decendents became birds.)

They weren't technologically advanced at all. Dunno where you got this idea. There was no dinosaur civilization.

But whatever you've been injesting, I think you should share!

;-)

Your notion that there must always be an intellectually human-like species is wrong. There's no reason to think that there's always some intellectually and technologically advanced critter here.

Answer 3

Unfortunately the dinosaurs did not free up their foelimbs to manipulate things so did not then develop large brains. If dinosaurs left Earth they did, however, leave a lot of bones lying about which became fossils and pointed to our knowledge of them that they coulod not build space craft. You have a warp(!)ed imagination if you think dinosaurs could fly away on a spaceship. An intergalactic Ark, no less.
