Songlingornis is an extinct genus of ornithuromorph dinosaurs from the Early Cretaceous. Its fossils have been found in the Jiufotang Formation of Liaoning (PRC). The age of these rocks is somewhat disputed, but probably around the early Aptian, 125-120 million years ago. Only one species, Songlingornis linghensis, is known at present.
Shanweiniao is a genus of long-snouted enantiornithean birds from Early Cretaceous China. One species is known, Shanweiniao cooperorum. There is one known fossil, a slab and counterslab. The fossil is in the collection of the Dalian Natural History Museum, and has accession number DNHM D1878/1 and DNHM1878/2. It was collected from the Lower Cretaceous Dawangzhengzi Beds, middle Yixian Formation, from Lingyuan in the Liaoning Province, China.
Longicrusavis is an extinct genus of basal ornithuromorph bird found only at Dawangzhangzi village in Liaoning Province, China. Longicrusavis was a ground dwelling carnivore, a wader, and part of biological family Hongshanornithidae, considered to have been a dominant species in the Jehol Biota, the prehistoric Chinese ecosystem which supported them. The name Hongshanornithidae represents one of China's oldest recorded cultures in the region, the Hongshan culture.
Hongshanornithidae is an extinct group of early ornithuromorph birds from the early Cretaceous period of China. It includes the genera Hongshanornis and Tianyuornis from the Yixian Formation of Inner Mongolia, Longicrusavis from the Yixian Formation of Liaoning Province, Parahongshanornis from the Jiufotang Formation of Liaoning Province, and Archaeornithura, the oldest known member, from the Huajiying Formation of Hebei Province.
Songlingornithidae is a family of basal euornithean dinosaurs from the Early Cretaceous of China. All known specimens come from the Jiufotang Formation and the Yixian Formation, dating to the early Barremian and Aptian ages, 125–120 million years ago.
Yumenornis is an extinct genus of basal ornithuromorph dinosaurs known from the Early Cretaceous Xiagou Formation of Changma Basin, Gansu Province of northwestern China. Yumenornis was first named by Ya-Ming Wang, Jingmai O'Connor, Da-Qing Li and Hai-Lu You in 2013 and the type species is Yumenornis huangi.
Changmaornis is an extinct genus of basal ornithuromorph dinosaur known from the Early Cretaceous Xiagou Formation of Changma Basin, Gansu Province of northwestern China. Changmaornis was first named by Ya-Ming Wang, Jingmai K. O'Connor, Da-Qing Li and Hai-Lu You in 2013 and the type species is Changmaornis houi.
Jiuquanornis is an extinct genus of basal ornithuromorph dinosaur known from the Early Cretaceous Xiagou Formation of Changma Basin, Gansu Province of northwestern China. Jiuquanornis was first named by Ya-Ming Wang, Jingmai K. O'Connor, Da-Qing Li and Hai-Lu You in 2013 and the type species is Jiuquanornis niui.
Archaeornithura is an extinct genus of ornithuromorphs from the early Cretaceous period. It is known from two fossil specimens of a single species, Archaeornithura meemannae. The specimens have been dated to the Hauterivian age, 130.7 million years ago, making A. meemannae the oldest known ornithuromorph, the lineage that gave rise to modern birds, and contains all living birds as well as many of their extinct relatives.
Changzuiornis is an extinct genus of ornithuromorph bird from the Early Cretaceous of present-day China. It contains a single species, C. ahgmi.
Juehuaornis is an extinct genus of ornithuromorph dinosaurs from the Early Cretaceous of present-day China. It contains a single species, J. zhangi.
Dingavis is an extinct genus of ornithuromorph dinosaurs from the Early Cretaceous of present-day China. It contains a single species, D. longimaxilla.
Eogranivora is a bird genus, belonging to the Ornithuromorpha, that lived in the area of present-day China during the Early Cretaceous. Its type species is Eogranivora edentulata.
Tianyuornis is a genus of ornithuromorph birds from the Early Cretaceous period. Tianyuornis was unearthed from lake deposits in the Yixian Formation of Inner Mongolia, China. Tianyuornis, like its other relatives, were similar in size to modern phoebes.
Abitusavis is an extinct genus of ornithuromorph dinosaurs from the Early Cretaceous Yixian Formation of China. The genus contains a single species, Abitusavis lii, known from a nearly complete skeleton.
Similiyanornis is an extinct genus of ornithuromorph dinosaurs from the Early Cretaceous Jiufotang Formation of China. The genus contains a single species, Similiyanornis brevipectus, known from a complete skeleton with feathers.
Mengciusornis is an extinct genus of basal ornithuromorph dinosaurs from the Early Cretaceous of China. It contains one species, M. dentatus, remains of which have been found in the Jiufotang Formation. Together with the closely related Schizooura it makes up the family Schizoouridae.
Meemannavis is a genus of ornithuromorph dinosaurs from the Early Cretaceous (Aptian) Xiagou Formation of Gansu Province, China. The genus contains a single species, Meemannavis ductrix, known from a partial skeleton including an incomplete skull and cervical and thoracic vertebrae. The lower jaw and tip of the upper jaw of the Meemannavis holotype are toothless, but it may have had teeth nearer the back of the upper jaw.
Brevidentavis is a genus of ornithuromorph dinosaurs from the Early Cretaceous (Aptian) Xiagou Formation of Gansu Province, China. The genus contains a single species, Brevidentavis zhangi, known from a specimen including a partial skull and cervical vertebrae. The Brevidentavis holotype shows unusually blunt teeth in its lower jaw, which the describing authors suggest may indicate a specialized diet. Its dentition shows similarities with those of hesperornitheans, and indeed it may be an early member of that group.
Migmanychion is an extinct genus of maniraptoran theropod dinosaur from the Early Cretaceous Longjiang Formation of China. The genus contains a single species, M. laiyang, known from an incomplete left forelimb.
