The largest flying animal launched itself into the air after plucking prey from the water.
A newly discovered relative of a pterosaur ruled the skies for millions of years.
Some of the secrets of the largest animal to have ever flown have been revealed.
The wetlands of Texas were home to a pterosaur that lived over 67 million years ago. It would have had to jump up to 2.5 meters into the air, followed by powerful flaps, to get into the sky.
For the first time, the scientists have described a smaller relative, called the Quetzalcoatlus lawsoni, which would have been 888-282-0465 888-282-0465 888-282-0465 888-282-0465 888-282-0465 888-282-0465. The pterosaurs would have eaten a range of fish and small aquatic prey.
Professor Brian Padian, co-editor of a series of recently published papers on the animals, says, "These ancient flying reptile are legendary, although most of the public conception of the animal is artistic, not scientific."
This is the first real look at the entire animal, as far as we know. The results are revolutionary for the study of pterosaurs, the first animals to evolve powered flight.
The papers were published in a journal.

The discovery of hundreds of bones in Big Bend National Park led to the naming of the largest pterosaur. Many smaller bones were found in other areas of the park, but the large bones of the left wing were the only description of the species.
It was not certain if the smaller bones were from young Q. northropi or a different species. Scientists decided that they were probably a new species of Quetzalcoatlus, but did not carry out any further analysis to find an exact species.
Scientists analyzed these smaller bones and found that they have a number of differences from the larger Q. northropi. The giant's skull structure and spine suggest that two other species of pterosaur were living side-by-side with it.
The majority of the finds are named after the man who first discovered them. The species had a wingspan of 4.5 meters and was found in rocks that were 69 million years old.
Researchers found bones of a third species of pterosaur, which had a wingspan of three meters, from around the same period.
The site has the potential for more species to be found, but they will need further finds as the current unclassified bones lack the necessary detail to determine what they are.
The sky is not enough.
The researchers were able to find out how the different species would have behaved by studying the different bones.
The researchers found that the beak was too delicate to have eaten meat or been taken from a carcass. They suggest the animals probably acted like a large heron, plucking fish and other small animals out of the water and swallowing them whole.
Researchers found that the species would have been able to fly by using a jumping start. The size of its wings would have prevented it from using a running start.
"If they could jump twice their hip height, to eight feet, the wings would be able to clear the ground and execute a deeper flight stroke," Brian says. It depends on the power from the legs, but this may be the best option.
The large head of the Quetzalcoatlus may have helped it to complete turns, as it would have soared like modern condors and vultures. The front limbs of a bird are similar to the front limbs of pterosaurs.
It would have acted like an airplane when it came to landing, slowing until it fell out of the sky.
The animal had to flap its wings to stall and slow its descent before it lands with its back feet. "Then it puts down its front feet and walks away."
The four-legged posture saw the animal walk in a different way than any other animal alive today. The bone structure of the pterosaur would have prevented vampire bats from using their wings.
"To avoid tripping, the animal first raised its left arm, then advanced its left leg in a full step, then it placed the hand on the ground," Brian explains. The process was repeated with the left limb. The process seems cumbersome to us, but the animal could do it quickly and easily.
There are tracks in France that are too oddly shaped for a quadruped to have made them.
The researchers hope to discover more about the shape of the wing and how it would affect the flight.
The pterosaurs ruled the skies for millions of years, but in the end another flying object brought their time to an end. The end for the dinosaurs and their flying relatives was spelled by the meteorite which hit Mexico 66 million years ago.
