Cearadactylus

Cearadactylus is a etinct genus of the Pterosaur order that lived in the Early-Mid Cretaceous of South America and presumably North America. Cearadactylus had a crestless skull that could reach a length of 57 centimetres.

Jurassic Park novel
In the novel version of Jurassic Park, Cearadactylus lived inside the aviary of the Pteratops Lodge. A scene similar to this with Pteranodon was put into Jurassic Park III. Also like the JP3 Pteranodons, the Cearadactylus were probably significantly genetically altered, being more agressive and powerful than their real counterparts. In Jurassic Park III, Pteranodon was chosen due to the fact that it was more well known. In the Jurassic Park novel, they were often confused by the characters with Pterodactyls, but Alan Grant recognized them as Cearadactyls.
