Interpretations of the habits of basal groups have changed profoundly. "Dimorphodon", envisioned as a puffin analogue in the past, is indicated by its jaw structure, gait, and poor flight capabilities, as a terrestrial/semiarboreal predator of small mammals, squamates, and large insects. Its robust 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.
