Cearadactylus is an extinct genus of the pterosaur order that lived in the Early Cretaceous Santana Formation of Brazil. Cearadactylus had a crestless skull that could reach a length of 57 centimeters.

Wikipedia has a more detailed and comprehensive article on Cearadactylus


In Jurassic Park, Cearadactylus lived inside the Isla Nublar Aviary. They were let out into the aviary as to acclimate them to the enclosure's environment. However, they were discovered to have a hostily territorial behavior. They were attacking maintenance crews that were working on the Pteratops Lodge; a second hotel where visitors could observe the pterosaurs at flight level. They would fold up their wings like bats and dive, striking workmen with such force, incapacitating them. Later in the novel, they were confused by the characters with Pterodactylus, but Alan Grant recognized them as Cearadactylus. According to Grant's description, they had membranous wings that they could fold up and walk with and clawed forearms for grasping fish. That was precisely, ultimately put into the Isla Sorna Aviary scene in Jurassic Park III.

It is briefly unknown if they ultimately survived the Jurassic Park incident, but it is also likely, as they may have escaped the Napalm Bombing and migrated to Isla Sorna.


  • In the novel, the counting system counts six pterosaurs, although Dr. Wu specifically says that they have four pterosaurs.
