Chaoyangopteridae

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.

Chaoyangopterus is a genus of chaoyangopterid pterosaur known from a partial skeleton found in Liaoning, China. Chaoyangopterus was found in rocks dating back to the Aptian-age Lower Cretaceous Jiufotang Formation of Dapingfang, Chaoyang.

Eoazhdarcho is a genus of probable chaoyangopterid pterosaur named in 2005 by Chinese paleontologists Lü Junchang and Ji Qiang. The type and only known species is Eoazhdarcho liaoxiensis. The fossil was found in the Aptian-age Lower Cretaceous Jiufotang Formation of Chaoyang, Liaoning, China.

Microtuban is an extinct genus of azhdarchoid pterosaur known from the Late Cretaceous of northern Lebanon.

Apatorhamphus is an extinct genus of azhdarchoid pterosaur from the Kem Kem Group of Morocco. It might have been part of the Chaoyangopteridae. It is only known from a few snout fragments and it likely had a wingspan of between

Jidapterus is a genus of chaoyangopterid pterosaur from the Aptian-age Lower Cretaceous Jiufotang Formation of Chaoyang, Liaoning, China. The genus was in 2003 named by Dong Zhiming, Sun Yue-Wu and Wu Shao-Yuan. The type species is Jidapterus edentus. The genus name is derived from Jílín Dàxué or "Jilin University" and a Latinized Greek pteron, "wing". The specific name means "toothless" in Latin.

Shenzhoupterus is a genus of chaoyangopterid pterosaur from the Jiufotang Formation of modern-day Liaoning, China. Fossil remains of Shenzhoupterus date back to the Early Cretaceous period, approximately 120 million years ago.

Meilifeilong () is an extinct genus of chaoyangopterid pterosaurs from the Early Cretaceous Jiufotang Formation of China. The genus contains two species. The type species, M. youhao, was described in 2023 based on an almost complete skeleton and a partial isolated skull. The second species, M. sanyainus, was described earlier in 2023 as a species of Shenzhoupterus, based on a complete skull and skeleton. Meilifeilong is the best-preserved and most complete chaoyangopterid currently known.
