This creature had wingspans believed to be up to thirty meters.
David Attenborough said in one of his BBC programs that in the age
of the dinosaurs, dragonflys had a wingspan of two feet!
Ancient flying reptiles called pterosaurs were adapted to fly in a slow, controlled manner in gentle tropical breezes, researchers say.
Their conclusions are drawn from the first detailed aerodynamic study of the wings, which suggests they did not evolve to fly fast and powerfully in stormy winds.
The research, published in the Proceedings of the Royal Society, may also explain how the creatures were able to become the largest flying animals ever known.
