Pterosaurs, First winged reptiles were clumsy flyers, capable of short distances: Research
Pterosaurs like pterodactyl were some of the first largest animals to fly but research now suggests that the first reptile aviators were clumsy flyers. This research may throw new light on the evolution of flight more generally. Pterosaurs are considered the earliest vertebrates to have evolved powered flight. Prof Venditti and his team estimated the wing size and body mass from their fossilized remains.
