Caupedactylus is an extinct genus of tapejarid azhdarchoid pterosaur known from the Early Cretaceous period (Albian stage) of what is now the Romualdo Formation of the Araripe Basin in northeastern Brazil.

[1] Caupedactylus is known from the holotype specimen MN 4726-V, probably found in the Araripe basin in a layer of the Romualdo Formation dating from the Albian, about 110 million years old.

The postcrania contain the right shoulder girdle, left coracoid, sternum, right humerus and the proximal part of the first phalanx of the wing finger.

[1] Kellner estimated the wingspan of Caupedactylus at 3.3 meters (11 ft), making it the largest known tapejarine.

The point of the snout curves downwards combined with a slightly concave lower edge of the upper jaw.

[1] In 2019 however, Kellner (the describer of Caupedactylus) and colleagues had included it in a phylogenetic analysis where it was recovered as the basalmost tapejarine.
