It is the giant flying lizard Quetzalcoatlus, the largest flying creature that ever existed on Earth. They dominate the vast sky 166 million years ago and almost no natural enemies. Even with the largest and most ferocious dinosaurs, they can become their prey.

Quetzalcoatlus giant lizard lives in the late Cretaceous period in North America (Late Cretaceous about 68 - 65.5 million years ago). Their names are named after the flying feathered Aztec God of the ancient Aztec civilization in Central America.

With its large size, wingspan of up to 15m, 4.8-5.5m high and weighing from 210 to 250 kg but thanks to its hollow structure, Quetzalcoatlus can fly easily and become a scary assassin in the sky for any animal.

Due to the oversized wingspan, this lizard often has to take off from high cliffs or run across the wide ground like a flying plane.

If standing upright, this flying lizard is as tall as an adult giraffe.

The large size made it possible for every other creature to watch their shadow on the ground, even if it was a violent tyrant dinosaur, without exception.

Not only hunting on the mainland, Quetzalcoatlus giant lizard also wingspan hovering over Creataceous shores to catch underwater prey.

Based on the cilia found in fossils, the researchers believe that this flying creature is hot-blooded like today's birds and can lay eggs.

They can control hovering and balancing because of the large brain with large areas.

Researcher Sankar Chatterjee has created a computer model to find out how such a heavy creature with delicate wings can fly in the sky.

After studying Chatterjee realized that, most of the time, these giant creatures flew in the sky, they were able to soar into the air and glide very well. But they have a little difficulty when taking off or landing.

This lizard can fly as high as 3000 to 4500 meters and rush at 80 miles an hour, equivalent to an airplane traveling at 128 km / h. At this rate, almost no prey can escape their attack from above.

On the ground, they will fold their wings, move with their hind legs and often wander around lakes to find small foods like fish and insects. At that time, the strong wings will act as the front legs to help them cling to moving in the uneven area like cliffs.

Thanks to the saddle-like structure, this species can easily filter small aquatic organisms. The beak of the flying lizard is very hard, long and pointed, this is their extremely effective hunting weapon.
