This is my very own theory and was not copied from anyone~I believe that dinosaurs evolved into dragons. Now why I say this is because dinosaurs were more related to birds then reptiles. Many scientist believe that later dinosaur species evolved into early birds. What if they did, but not completely. What if they evolved half-way. Bird/dinosaur. Which is the exact image of what a dragon may appear to look like. Long four-legs for supporting weight, light leathery wings and a dinosaur-like snout. Fire cam with evolution. Flight came with experience. The first bird-dinosaurs were early raptors, covered in feathers or fluffy hair on their bodies. As dinosaurs evolved, these feathers may have grown out, letting the creature glide from tree to tree. Then came the finally stage in which dinosaur became bird, and could soar through the air, flapping it's feathery wings. The pteranadon dinosaur was a flying dinosaur with a long bird-like beak and short stiff legs. This could have been an early form of dragon, then it could have evolve to experience new evolution standards.
