Quetzalcoatlus
The Quetzalcoatlus are extinct animals that ruled the skies towards the end of the Dinosaur Age. These pterosaurs were as tall as the giraffe, and the biggest ones were the largest of all flying creatures during that time period. Through evolution of this species, they helped produce some of the largest flying creatures in the world. They’re members of the azhdarchids, which existed between 144 and 66 million years ago. They have pointed skulls, and some even had short crests, located on the back of their heads. Similar to giraffes, they had long necks, but also long legs and short wings, which were all in proportion to their bodies. They’re pretty terrifying, to say the least, and we agree that looking and pictures of them is enough for us. We wouldn’t want to see these roaming around in the streets (Earth Archives).
