You bet they did.
The biggest proof of their having existed is the BONES!! Bones or fossils (bones that have turned to rock) are excellent proof of one very obvious fact. Something died there and left those bones!
Yes they did. We have proof that they did by finding the bones of many that existed thousands of years in the past. Yes,dinosaurs did exist 65 million years ago. They also became extinct 65million years ago. Whats left of them now is fossils hidden inside layers of rock. The dinosaurs lived in three different Mesozoic time periods. The Trassic, Jurassic, and Cretaceos. In the Early Trassic the first dinosaur walked the Earth. In the Late Trassic more dinosaurs evolved. The Jurassic was the first time period to have dinosaurs flourishing. Mostly were giants like Apatosaur. Then the last time period, Cretaceos. The Cretaceos held some of the most famous dinosaurs, like Tyrannosaurus Rex and Tricerotops. Then they all became extinct at the end of the Cretaceos. So dinosaurs did exist at one period of time.
Yes, dinosaurs really did exist millions of years ago. There have been dinosaur bones found all over the world.
Dinosaurs existed. We're not too sure if dragons did. In other words, Dragons exist in the "mind" Dinosaurs exist in the museums. Dragons also exist in literature and in scuplture. Not all dinosaurs are extinct.
