Do dinosaur and dragon are the same?

Answer 1

Dragons are fictional creatures. They usually have wings, hind limbs, and arms; no real vertebrates have six limbs. Dragons are often depicted breathing fire; no organism could do that.

Dinosaurs were real reptiles.

The myths of dragons may have come from ancient people looking at dinosaur fossils without knowing how to interpret the fossils. After all, the much of a dragon's body looks like that of a theropod, with the addition of a pterosaur's wings and sometimes horns and frill, like a ceratopsian.
