Jiufotang fauna

Confuciusornis is a genus of basal crow-sized avialan confuciusornithid theropod dinosaur from the Early Cretaceous Period of the Yixian and Jiufotang Formations of China, dating from 125 to 120 million years ago. Like modern birds, Confuciusornis had a toothless beak, but closer and later relatives of modern birds such as Hesperornis and Ichthyornis were toothed, indicating that the loss of teeth occurred convergently in Confuciusornis and living birds. It was thought to be the oldest known bird to have a beak, though this title now belongs to an earlier relative Eoconfuciusornis. It was name

Nemicolopterus is a dubious genus of tapejaromorph pterosaur, based on a very small specimen described as the smallest known "adult" pterosaur to date. It lived in the Jehol Biota 120 million years ago.

Sinopterus (meaning "Chinese wing") is a genus of tapejarid pterodactyloid pterosaur from the Aptian-age Lower Cretaceous Jiufotang Formation of Chaoyang, Liaoning, China. It was first described and named by Wang Xiaolin and Zhou Zhonghe. Historically, there were multiple species attributed to the genus although only one is considered to be valid. Sinopterus is known for its proportionally large skull, which has a bird-like pointed beak lacking teeth, and a long bony crest that starts with a tall premaxilla and goes back along the middle of the skull to form a point overhanging the rear of the

Liaoningopterus, sometimes misspelled as "Liaoningopteryx", was a genus of anhanguerid pterodactyloid pterosaur from the Barremian-Aptian-age Lower Cretaceous Jiufotang Formation of Chaoyang, Liaoning, China.

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.

Longipteryx is a genus of prehistoric bird which lived during the Early Cretaceous (Aptian stage, 120.3 million years ago). It contains a single species, Longipteryx chaoyangensis. Its remains have been recovered from the Jiufotang Formation at Chaoyang in Liaoning Province, China. Apart from the holotype IVPP V 12325 - a fine and nearly complete skeleton — another entire skeleton (IPPV V 12552), some isolated bones (a humerus and furcula, specimens IPPV V 12553, and an ulna, IPPV V 12554) and many other specimens are known to date.

Liaoxipterus is a genus of pterodactyloid pterosaur from the Barremian-Aptian-age Lower Cretaceous Jiufotang Formation of Chaoyang, Liaoning, China. The type species is Liaoxipterus brachyognathus. The genus name is derived from the discovery locality Liaoxi and a Latinised Greek pteron, "wing". The specific name is derived from Greek brachys, "short" and gnathos, "jaw".

Guidraco (Chin. gui (鬼) "malicious ghost" + Lat. draco "dragon") is an extinct genus of toothed pterodactyloid pterosaur known from the Early Cretaceous of Liaoning Province, northeast China. According to many recent studies, Guidraco is a member of the group Anhanguerinae, a subfamily belonging to the larger group Anhangueridae.

Liaoconodon is an extinct genus of early mammal from the early Cretaceous (early Aptian stage, approximately 120 Ma). It is a eutriconodont which lived in what is now the Jianchang of Liaoning Province, eastern China. It is known from the holotype IVPP V 16051, which consists of nearly complete skeleton and skull. It was found in the Jiufotang Formation (Jehol Biota) near Xiaotaizi, Lamadong. It was first named by Jin Meng, Yuanqing Wang and Chuankui Li in 2011 and the type species is Liaoconodon hui.

Cathayornis is a genus of enantiornithean birds, from the Jiufotang Formation of Liaoning, People's Republic of China. It is known definitively from only one species, Cathayornis yandica, one of the first Enantiornithes found in China. Several additional species were once incorrectly classified as Cathayornis, and have since been reclassified or regarded as nomina dubia.

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.

Boluochia is an extinct genus of enantiornithean bird. It lived during the Early Cretaceous in the time span 121.6-110.6 mya (late Aptian-early Albian) and is known from fossils found in the Jiufotang Formation of Liaoning province, People's Republic of China. Boluochia was first described by Zhou in 1995. A re-analysis of the specimen by Jingmai O'Connor and colleagues found that it was closely related to Longipteryx and could be assigned to the family Longipterygidae.

Cuspirostrisornis is a genus of enantiornithean bird. Only one species is known, Cuspirostrisornis houi, though some researchers believe this to be a synonym of the similar species Cathayornis yandica. It is known from one fossil found in the Jiufotang Formation in Liaoning province, People's Republic of China. The Jiufotang Formation is dated to the Early Cretaceous period, Aptian age, 120.3 +/-0.7 million years ago.

Chiappeavis is a genus of enantiornithean bird from Early Cretaceous of northeastern China. The only species is Chiappeavis magnapremaxillo. Chiappeavis is classified within the family Pengornithidae. It is known from a single, almost complete skeleton including feather impressions discovered in the Jiufotang Formation of the Jehol Group. Long feathers formed a fan-shaped tail that was probably employed in flight.

Huaxiadraco (meaning "Hua Xia [China] dragon") is a genus of tapejarid pterodactyloid pterosaur from the Aptian-age Lower Cretaceous Jiufotang Formation of Chaoyang, Liaoning, China. It is the third valid genus of tapejarid from the Jehol Biota, after Sinopterus and Eopteranodon. It contains one species, Huaxiadraco corollatus, originally assigned to the defunct genus Huaxiapterus.

Shuilingornis (meaning "pretty and vivid bird") is an extinct genus of gansuid euornithean birds from the Early Cretaceous Jiufotang Formation of China. The genus contains a single species, S. angelai, known from a nearly complete articulated skeleton. As a member of the Gansuidae, Shuilingornis represents one of the earliest known birds known to demonstrate semi-aquatic adaptations.

Xiangornis is an enantiornithean bird from the Lower Cretaceous Jiufotang Formation of Western Liaoning, China.

Philydrosaurus is an extinct genus of choristoderan which existed in China during the Early Cretaceous. The type species P. proseilus was named in 2005. Philydrosaurus was found from the Jiufotang Formation and is slightly younger than Monjurosuchus, which was found from the Yixian Formation.

Neobohaiornis is an extinct genus of bohaiornithid enantiornithean birds from the Early Cretaceous (Aptian-aged) Jiufotang Formation of Liaoning Province, China. The genus contains a single species, N. lamadongensis, known from a well-preserved skeleton with feather impressions. == Discovery and naming == thumb|left|Life restoration The Neobohaiornis holotype specimen, MHGU-0288, was discovered in sediments of the Jiufotang Formation near Lamadong in Jianchang County of Liaoning Province, northeastern China. The specimen is a nearly complete skeleton preserved in dorsal view. Feather traces ar

Gracilornis is an extinct genus of early bird from the lower Cretaceous (Aptian stage). It is a cathayornithid enantiornithine which lived in what is now western Liaoning Province, China. It is known from a nearly complete skull and postcranial skeleton, which was found from the Jiufotang Formation, in Chaoyang. It was first named by Li Li and Hou Shilin in 2011 and the type species is Gracilornis jiufotangensis. The generic name is derived from Latin gracilis, "slender" and Greek ornis, "bird", and refers to its slender skeleton. The specific name was named after the Jiufotang Formation, in w

Fossiomanus is an extinct genus of tritylodontid mammaliamorphs from the Early Cretaceous of China. It includes one species, F. sinensis, which is known from a single nearly complete skeleton from the Aptian Jiufotang Formation. Features of its limbs and vertebrae indicate that Fossiomanus was adapted towards a fossorial lifestyle.
