They 1st appeared during the Triassic period. Until recently, most scientist would not have put pterossaurs in the same class as birds in terms of flying ability. It is very difficult to say how pterosaurs changed over time because the earliest fossils we have are of pterosaurs whose forth finger has already turn into a wing, says Fabic dalla vecchia, an italian researcher.
