dentition caused Campylognathoides to be seen as a generalist or a terrestrial predator of small vertebrates, but the highly robust humerus and high-aspect wing morphology, suggest it may have been capable of grabbing prey on the wing. The small insectivorous Carniadactylus and the larger Eudimorphodon were highly aerial animals and fast, agile flyers with long robust wings. Eudimorphodon has been found with fish remains in its stomach, but its dentition suggests an opportunistic diet. Slender-winged Austriadactylus and Caviramus were likely terrestrial/semiarboreal generalists. Caviramus likely had a strong bite force, indicating an adaptation towards hard food items that might have been chewed in view of the tooth wear. Some Rhamphorhynchidae, such as Rhamphorhynchus itself or Dorygnathus, were fish-eaters with long, slender wings, needle-like dentition and long, thin jaws. Sericipterus, Scaphognathus and Harpactognathus had more robust jaws and teeth (which were ziphodont, dagger-shaped, in Sericipterus), and shorter, broader wings. These were either terrestrial/aerial predators of vertebrates or corvid-like generalists. Wukongopteridae like Darwinopterus were first considered aerial predators. Lacking a robust jaw structure or powerful flying muscles, they are now seen as arboreal or semiterrestrial insectivores. Darwinopterus robustidens, in particular, seems to have been a beetle specialist. Among pterodactyloids, a greater variation in diet is present. Pteranodontia contained many piscivorous taxa, such as the Ornithocheirae, Boreopteridae, Pteranodontidae and Nyctosauridae. Niche partitioning caused ornithocheirans and the later nyctosaurids to be aerial dip-feeders like today's frigatebirds (with the exception of the plunge-diving adapted Alcione elainus), while boreopterids were freshwater diving animals similar to cormorants, and pteranodonts pelagic plunge-divers akin to boobies and gannets. An analysis of Lonchodraco found clusters of foramina at the tip of its beak; birds with similarly numerous foramina have sensitive beaks used to feel for food, so Lonchodraco may have used its beak to feel for fish or invertebrates in shallow water. The istiodactylids were likely primarily scavengers. Archaeopterodactyloidea obtained food in coastal or freshwater habitats. Germanodactylus and Pterodactylus were piscivores, while the Ctenochasmatidae were suspension feeders, using their numerous fine teeth to filter small organisms from shallow water. Pterodaustro was adapted for flamingo-like filter-feeding. In contrast, Azhdarchoidea mostly were terrestrial pterosaurs. Tapejaridae were arboreal omnivores, supplementing seeds and fruits with small insects and vertebrates. Dsungaripteridae were specialist molluscivores, using their powerful jaws to crush the shells of molluscs and crustaceans. Thalassodromidae were likely terrestrial carnivores. Thalassodromeus itself was named after a fishing method known as "skim-feeding", later understood to be
