Cearadactylus is an extinct genus of large anhanguerid pterosaur from the Early Cretaceous (Albian age) Romualdo Formation of Brazil. The only known species is C. atrox, described and named in 1985 by Giuseppe Leonardi and 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.

==Discovery== The holotype of Cearadactylus is MN 7019-V (formerly CB-PV-F-O93), which was discovered in the Romualdo Formation of the Santana Group in the Araripe plateau of northeastern Brazil. It consists of a single skull with a length of . It was traded to Italy in 1983 and bought by Borgomanero for his collection. The skull is severely damaged, especially on the top, and was perhaps reconstructed by the fossil dealer.
