The discovery of two small dinosaurs with bat-like wings a few years ago was a palaeontologist’s dream. Just how flight evolved in birds is something we’re still trying to nail down, and looking at this early evolution of bat-like wings in dinosaurs could give us a clue.
But a team of researchers has now pointed out that just because you have wings, it doesn’t necessarily mean you’re actually any good at flying.
Yi qi and Ambopteryx longibrachium are two species of theropod dinosaurs that lived around 160 million years ago, both of which had unusually elongated fingers, and a skin membrane stretching between them, similar to a bat’s wing.
This is an entirely different kind of wing to the one theropod dinosaurs evolved to fly with – the dinosaurs that eventually
