Eudimorphodon and Peteinosaurus were close neighbours: both animals were found in the Triassic rocks of the Cene region of Italy. And both pterosaurs had long tails. Eudimorphodon was the larger animal, however, and its teeth were more advanced than those of its distant cousin. The head of this fish-eating flying reptile was 7 cm long and the tips of the lower jaw were bent slightly downwards. The front of the mouth was armed with long, pointed teeth. The shape of the jaw and the arrangement of teeth enabled Eudimorphodon to snatch fish from the surface of the sea.
Along the sides of each of the upper and lower jaws, Eudimorphodon had many smaller teeth. Each tooth was armed with between three and five points. Fossilized stomach contents suggest that these teeth were used to crush the bones and scales of fish. Teeth used like this are often polished and flattened owing to the constant grinding of the tooth surface against the tough scales.
