Cearadactylidae

Cearadactylus is an extinct genus of large anhanguerid pterosaur from the Early Cretaceous 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.
