How long were the dinosaurs alive?

For Jodi, YES, there are some species that still live that remain relativly unchanged from there dinosaur ancestors, most however are fish such as the coelacanth, believed to have been extinct for millions of years and resurfacing (just one) first in 1836 and then several more in 1938 and found to be thriving at 150 to 700 m off the east coast of england in 1991.

The oldest dinosaur types are known from rocks in Argentina and Brazil and are about 230 million years old.

Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.

So you see, sid had extinction confussed with the first dinosaurs, and Mnt was right ;=)

I think it's a trick question because some animals that are still around where around in dinosaurs time, like some reptiles right?

They lived roughly from 230 Million years ago to 200 Million years ago.

I thought they all died out 65 million years ago when the meteor hit the Yucatan.

Unless you mean these Dinosaurs. They never did die, or did they......

Maybe I'm wrong.... I've been looking at code all day. LOL

And you can't forget, "Not the baby!!!"

Here's one we wish would become extinct
