Dinosaurs are related to birds the feathered friends we see in are every day life, but just imaging 70 million years ago, the largest flying dinosaurs glided throw are skies and that animal was the Quetzalcoatlus. The Quetzalcoatlus was not riley a dinosaur it was actually a flying reptile. Quetzalcoatlus from tail to tip of it's beck is 36ft to 39ft long and has a wing span of 33ft to 36ft long making it the biggest flying animal to ever live! The Quetzalcoatlus was basically the giant aircraft of the late cretaceous.
Quetzalcoatlus was probably a predator, scientist think it hunted fish on the ancient coasts and when it was inland it hunted baby dinosaurs or smaller dinosaurs.
