Pterosaur

Pterosaurs were flying dinosaurs which may have evolved into modern birds. They lifted their quite small, very light bodies on enormous membranous wings. Most pterosaurs lived on fish and their fossils are almost always found around lakes and the sea. It is thought that they migrated long distances like some modern birds.
