Chaoyangopteridae (or chaoyangopterids) is a family of pterosaurs within the larger group Azhdarchoidea. Chaoyangopterids lived mostly during the Early Cretaceous period, though possible members, Microtuban, Xericeps and Argentinadraco, may extend the fossil range to the Late Cretaceous.[1][6]
History
The
Description
Chaoyangopterids are distinguished from other pterosaurs by several traits of the nasoantorbital fenestra, a large hole on the side of the snout formed by the assimilation of the nares (nostril holes) into the antorbital fenestra. In members of this family, the nasoantorbital fenestra is massive, with the rear edge extending as far back as the braincase and jaw joint. The front edge is formed by a rod of bone known as the premaxillary bar, which is unusually slender in members of this family.[7]

Paleoecology
The members of the family Chaoyangopteridae are mostly known from Asia, though the possible member Lacusovagus occurs in South America[9] and there are possible fossil remains from Africa, including the possible member Apatorhamphus.[15] Microtuban may extend the clade's existence into the early Late Cretaceous.[13]
