Pterosaur: Scientists solve mystery of how the world's largest reptile flew!

Artists's impression of how the Pterosaur called Quetzalcoatlus might have looked

Scientists believe they have solved the mystery of how the world's biggest reptile was able to fly.

The giant pterosaur, called a Quetzalcoatlus, had a wingspan of around 12 metres - that's longer than the length of a double-decker bus!

It is the largest known animal to have ever taken to the sky, and lived on earth around 70 million years ago.

Experts believe it jumped at least two and a half metres in the air before lifting off by flapping its huge wings.

What did scientists find?

There were more than 200 species of pterosaur that lived on Earth

The team made the discovery by studying Quetzalcoatlus bones along with other pterosaur fossils, including some found nearly 50 years ago.

Fossils of the Quetzalcoatlus were first discovered in Big Bend National Park in America in 1971. This led to the identification of two new pterosaur species.

Experts at the University of Texas at Austin in the United States found that the Quetzalcoatlus might have lived like today's herons, hunting alone in rivers and streams.

They believe that it used its long, toothless jaws to sift for crabs, worms and clams from river bottoms and lakebeds.

Matthew Brown from the University of Texas at Austin said, "This is the first time that we have had any kind of comprehensive study."

"Even though Quetzalcoatlus has been known for 50 years, it has been poorly known," he added.
