Cacibupteryx (meaning "Cacibu [the Taino word for the lord of the sky] wing") is a genus of rhamphorhynchid rhamphorhynchoid pterosaur from the middle-late Oxfordian-age Upper Jurassic Jagua Formation of Pinar del Rio, Cuba. It is based on IGO-V 208, a partial but well-preserved uncrushed skull missing the tip of the snout, teeth, and lower jaw, and fragmentary left wing. The skull is 17 centimeters long (6.7 inches), is preserved in three dimensions, and has a broad roof. The wingspan and length were not estimated by the describers.
Although it is a unique genus, and it appears to be a rhamphorhynchid, not enough of the animal is known to classify it any farther. Although there is little overlapping material with contemporaneous Nesodactylus, the two are clearly different based on details of the elbow and quadrate. Cacibupteryx is one of the most complete Oxfordian pterosaurs, and demonstrates additional Oxfordian pterosaur diversity. Recent reviews have supported its assignment as a rhamphorhynchoid, with David Unwin suggesting it was a scaphognathine (in the subfamily of rhamphorhynchids with more robust jaws).
