The genus Aerodactyl contains three species: A. primus, A.gigadontus, and A. fragilis. The most notable difference between the three species is the size of the mandible, teeth, and the overall size of their bodies. In all three species, males have a larger, more brightly coloured crest. Although previously believed to be extinct, small numbers of the three species have been documented to be observed in isolated regions surrounding cliffs.
A. gigadontus is the largest, most aggressive species; A. primus is the most robust and docile species; A. fragilis is the smallest, and most brightly coloured, species.
The A. primus and A. gigadontus pictured are female, while the A. fragilis is male.
