Description
Raeticodactylus had a tall thin bony crest running along the midline of the front of the upper jaw, and a keel on the lower jaw; however, it does not seem to be closely related to Austriadactylus, the only other crested Triassic pterosaur named by the time Raeticodactylus was described. The teeth at the front of the upper jaw, in the premaxillae, were fanglike, whereas the teeth in the upper cheeks (the maxillae) had three, four, or five cusps, similar to those of Eudimorphodon. Raeticodactylus had a wingspan of about 135 centimeters (53 in), and may have been a piscivore, potentially feeding by skimming the water.[1] However, skim-feeding has since been disproven in pterosaurs, and the related Caviramus appears to have been an omnivore.[3]
