It is a genus of pterosaurs in the Pterosauridae superfamily, a large pterosaur with a crown and no teeth. Fossils were discovered in the Santana Formation in Brazil, dating back to the early Cretaceous period. The appearance resembles that of a toothless pterosaur, with the adult individual's head crown extending from the snout to the back of the head. The head crown of a fairy pterosaur is larger and more prominent than that of a toothless pterosaur. Both males and females have large crests, but females have relatively round crests. The body length is 2.5 meters, the wingspan is 5.4 meters, and the length of the skull is 90 centimeters. They seem to live along the coasts of South America, feeding mainly on fish.

It is a flying reptile that lived in the Late Cretaceous period and belongs to the pterosaur order. Renowned for its enormous wingspan, which can reach up to 6 to 7 meters. The head is particularly eye-catching, with a huge bony crown that may be used for display or gender recognition. The jaw of this pterosaur lacks teeth, which is quite rare among pterosaurs. Mainly feeds on fish and mollusks, using their sharp beaks to catch prey. Fossils have been discovered in North America and are one of the important species for studying paleobiodiversity and Late Cretaceous ecosystems.
