Rhamphorhynchus was a genus of long-tailed pterosaurs.
Its jaws bore needle-sharp teeth, angled inwards. These served as a net for catching fish, which have indeed been found in some fossil Rhamphorhynchus specimens’ stomachs.
It had large eyes and presumably hunted mainly at night, like today’s nocturnal marine birds.
It was related to both Dorygnathus (see the skeleton here) and Eudimorphodon (on display in the Triassic section).
