Pterosaurs were flying reptiles of the extinct clade or order Pterosauria. They are the earliest vertebrates who have evolved powered flight. They had a variety of lifestyles and were traditionally seen as fish-eaters, fruit-eaters, and predators of other pterosaurs.
Some of the pterosaurs lived close to the places where fossils were formed, but their bones were fragile and very poorly preserved. That’s why most pterosaur fossils were incomplete.
