We all know that T. Rex was the king of land during the Late Cretaceous, while Mosasaurus was the king of the oceans. However, there was a third king, who ruled not land nor sea, but the sky, it was the Quetzalcoatlus. It was a giant pterosaur so mighty, that it was named after an Aztec God. It had a wingspan larger than a small plane, was taller than 3 people stacked on top of eachother, and had a taste for baby dinosaurs, making it one ferocious prehistoric beast.
