[4] However, in 2013, Taissa Rodrigues and Alexander Wilhelm Armin Kellner concluded firstly that Pterodactylus fittoni was not a part of the genus Anhanguera and secondly that Ornithocheirus nasutus was not identical to it regardless.

[5] The generic name combines that of the Brazilian paleontologist Diogenes de Almeida Campos with a Latinized Greek πτερόν, pteron, "wing".

[1] The holotype, CAMSM B 54556, had been found in a layer of the Cambridge Greensand dating from the Cenomanian but probably containing reworked fossils from the older Albian.

[1] Pterodactylus sedgwickii had in 1859 been named by Richard Owen based on specimen CAMSM B54422, the front part of a snout from the Cambridge Greensand.

[4] However, this was not accepted by Rodrigues & Kellner, who, rejecting any identity between the Brazilian and English pterosaur material, named a separate Cimoliopterus cuvieri.

There is a unique combination of traits: the upper profile of the snout is straight or lightly curved; the midline ridge on the palate is extended forwards until the level of the rear margins of the second tooth pair; to the rear the distance between the teeth gradually increases; the second and third tooth pairs are obliquely pointed sideways; the front of the snout is slightly expanded.

There is a unique combination of traits: the snout is deep; the midline ridge on the palate towards the front reaches a position behind the third tooth pair.

colorhinus has a robust snout tip forming a large rosette to catch slippery prey such as fishes, indicating an animal of considerable size.

[1] Rodrigues and Kellner assigned Camposipterus to the clade Anhangueria, but incertae sedis, thus in an unknown position.

Some cladistic analyses published in the naming article suggested a position in the evolutionary tree above Cimoliopterus and below Cearadactylus atrox.

[1] In 2019, Jacobs et al. published a phylogenetic analysis that placed Camposipterus within the family Ornithocheiridae, more specifically the sister taxon of Cimoliopterus.
