I Cearadactylus is a genus of large Early Cretaceous (Albian) pterosaurs from South America. The only known species is Cearadactylus atrox, described and named in 1985 by Giuseppe Leonardiand Guido Borgomanero. The name refers to the Brazilian state Ceará and combines this with Greek daktylos, "finger", a reference to the wing finger of pterosaurs. The Latin atrox means "frightful", a reference to the fearsome dentition of the species.
This species of pterosaur appeared exclusively on this ride (simply called a pterodactyl). After the computer warned that the asteroid that caused the extinction of the dinosaurs will cause impact in 60 seconds (1 minute) the time rover passed by 2 Cearadactylus chicks that flapped their wings and squawked at the passengers. After that, the computer identified a full grown adult (possibly the mother of the chicks) swooping towards the vehicle.
