It had a wingspan up to 5.75 feet (1.75m) wide. It had a diamond-shaped flap of skin at the end of its long, thin, pointed tail. This meat-eater had long, narrow jaws with sharp teeth that pointed outwards. It had tiny legs.Rhamphorhynchus lived during the late Jurassic period, roughly 150 million years ago. This was a time when there were many dinosaurs, including the enormous sauropods like Apatosaurus and Brachiosaurus. Rhamphorhynchus was a carnivore (a meat-eater) and probably ate fish.Rhamphorhynchus flew well using large, light-weight wings. Its long tail with a diamond-shaped flap of skin at the end helped stabilize it in flight. Its tiny legs probably made Rhamphorhynchus a poor runner.
Rhamphorhynchus fossils have been found in Solnhofen, Germany, and Tanzania. It was named by Meyer in 1847.
