==Discovery== In 1971, Alexandre Dobruski and his son João Gustavo Dobruski, discovered a fossil site near Cruzeiro do Oeste in Paraná. Only in 2011, paleontologists Paulo César Manzig and Luiz C. Weinschütz visited the location. A bone bed proved to be present with hundreds of specimens of a pterosaur that in 2014 was named Caiuajara. Among them were some bones belonging to a second pterosaur species. These remains, both of Caiuajara and the new taxon, were prepared by volunteer Vilson Greinert.
