There are many adaptations of the head and jaws of pterosaurs, so it is quite certain that different forms used different feeding methods, as birds do. Overall, most fossils have been found in marine strata, which suggests that they could fly well over water, and that fish were on the menu for many species. The jaws of fish-eaters was long and often held forward-pointing teeth, good for catching fish (see "Anhanguera"). Remains of a last fish supper have been found in "Pteranodon".
