DIET
Rhamphorhynchus was a carnivore (a meat-eater) and probably ate fish.

LOCOMOTION
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.

CLASSIFICATION
Rhamphorhynchus was a pterosaur, a flying reptile closely related to the dinosaurs. By definition, all dinosaurs were diapsid reptiles with an upright stance. Pterosaurs probably had a semi-upright stance, and were not dinosaurs. There is a small minority of paleontologists who think that the pterosaurs' stance could have been upright and that pterosaurs should therefore be included in the clade of dinosaurs (being derived theropods). Either way, dinosaurs and pterosaurs are certainly closely related.

Rhamphorhynchus was a:

• Vertebrate
• Tetrapod
• Diapsid - these include all the reptiles (except turtles) and birds. They are distinguished by having two holes in the rear upper part of their skulls and two holes behind the eyes.
• Archosaur - this group includes dinosaurs, crocodilians, pterosaurs, birds, etc.
• Pterosaur - flying reptile, including Dimorphodontids, Anurognathids, Scaphognathidae, Rhamphorhynchid, Protopterodactyloids, Pterodactyloids, Dsungaripterids, etc.
• Rhamphorhynchoid ("prow beaks") - early pterosaurs that appeared during the Triassic period and went extinct at the end of the Jurassic, that had protruding teeth in pointed jaw, long tail, short neck, and long, narrow wings. These were among the first flying vertebrates and probably flapped their wings to fly. These include Eudipmophodon, Camplognathoides, Rhamphorhynchus, and Dorygnathus.
  • Genus Rhamphorhyncus
  • Species include:
    • R. gemmingi, with the sharpest snout
    • R. longiceps, the largest
    • R. intermedius (perhaps a juvenile R. longiceps) and others.
