The famous winged dinosaur Archaeopteryx was capable of flying, according to a new study.

An international research team used powerful X-ray beams to peer inside its bones, showing they were almost hollow, as in modern birds, reported.

The creature flew like a pheasant, using short bursts of active flight, said scientists.

Archaeopteryx has been a source of fascination since the first fossils were found in the 1860s.

Treading the line between birds and dinosaurs, the animal was a similar size to a magpie, with feathered wings, sharp teeth and a long bony tail.

After scanning Archaeopteryx fossils in a particle accelerator known as a synchrotron, researchers found its wing bones matched modern birds that flap their wings to fly short distances or in bursts.

Lead researcher Dennis Voeten of the European Synchrotron Radiation Facility (ESRF), the European Synchrotron facility in Grenoble, France, said, "Archaeopteryx seems optimized for incidental active flight.

"We imagine something like pheasants and quails. If they have to fly to evade a predator they will make a very quick ascent, typically followed by a very short horizontal flight and then they make a running escape afterwards."

The question of whether Archaeopteryx was a ground dweller, a glider or able to fly has been the subject of debate since the days of Darwin.

Steve Brusatte, of the University of Edinburgh, the UK, who is not connected with the study, said this was the best evidence yet that the animal was capable of powered flight.

"I think it's case closed now. Archaeopteryx was capable of at least short bursts of powered flight.

“It's amazing that sticking a fossil into a synchrotron can reveal so much about how it behaved as a real animal back when it was alive."
