Auroraceratops, meaning "dawn horned face", is a genus of bipedal basal neoceratopsian dinosaur, from the Early Cretaceous of north central China. The etymology of the generic name refers to its status as an early ceratopsian and also to Dawn Dodson, wife of Peter Dodson, one of the palaeontologists who described it.
Yanornis is an extinct genus of fish-eating Early Cretaceous birds. Two species have been described, both from Liaoning province, China: Yanornis martini, based on several fossils found in the 120-million-year-old Jiufotang Formation at Chaoyang, and Yanornis guozhangi, from the 124-million-year-old Yixian Formation.
Sinovenator is a genus of troodontid dinosaur from China. It is from the early Cretaceous Period.
Gansus is a genus of aquatic birds that lived during the Aptian age of the Early Cretaceous (Aptian-Albian) period in what are now Gansu and Liaoning provinces, western China. The rock layers from which their fossils have been recovered are dated to 120 million years ago. It was first described in 1984 on the basis of an isolated left leg. It is the oldest-known member of the Ornithurae, the group which includes modern birds (Neornithes) and extinct related groups, such as Ichthyornis and Hesperornithes.
The Xiagou Formation is the middle strata of the Xinminbao Group. It is named for its type site in Xiagou, in the Changma Basin of Gansu Province, northwestern China and is considered Early Cretaceous in age. It is known outside the specialized world of Chinese geology as the site of a Lagerstätte in which the fossils were preserved of Gansus yumenensis, the earliest true modern bird.
Hongshanornis is a genus of ornithuromorph birds known from early Cretaceous lake deposits of the Yixian Formation, Inner Mongolia, China. The holotype specimen, recovered in 2005, is currently held by the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing. It was found in the Jianshangou fossil beds, dated to 124.6 million years ago. Three additional specimens have been reported, though only one of those has been definitively identified as belonging to Hongshanornis. This latter specimen was found in the Dawangzhangzi fossil beds, which are about 122 million years old.
Suzhousaurus is a genus of large therizinosauroid dinosaur from the Early Cretaceous of China. The genus is known from two specimens discovered on the Xiagou Formation and Zhonggou Formation—which are situated in the Xinminbao Group. These findings were made during field-works in 1999 and 2004. Though Suzhousaurus is known from these two specimens, an earlier named and described therizinosauroid from the adjacent basin, "Nanshiungosaurus" bohlini, may be synonymous with the former. However, Suzhousaurus can not be compared to this species due to non-overlapping material and the loss of the same. Moreover, this synonymy will result in Suzhousaurus bohlini with "N". bohlini having priority.
Archaeorhynchus is a genus of beaked avialan stem-birds from the early Cretaceous period. A fossil of its only known species, Archaeorhynchus spathula, was first reported in 2005 by Zhou & Zhang to have been found in Yixian Formation rocks at Yixian, Liaoning province, China, showing a well-preserved and essentially complete skeleton. Two more complete specimens were found in Lower Cretaceous deposits of Jianchang, Liaoning, northeastern China, preserving new anatomical information. These deposits are 120 million years old, whereas the original specimen was 125 million years old, meaning the age range for this species is 125-120Ma.
Xiongguanlong is an extinct genus of tyrannosauroid theropod from the Early Cretaceous period of what is now China. The type and only species is X. baimoensis. The generic name comes from Jiayuguan City and the Mandarin word "long" which means dragon. The specific epithet, "baimoensis" is a latinization of the Mandarin word for "white ghost" in reference to one of the geological features of the type locality.
Beishanlong is a genus of giant ornithomimosaurian theropod dinosaur from the Early Cretaceous of China. It is the second-largest ornithomimosaur discovered, only surpassed by Deinocheirus.
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.
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.
Meemann Chang also known as Zhang Miman, is a Chinese paleontologist at the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP). She completed her undergraduate studies at Moscow University and completed her PhD thesis entitled 'The braincase of Youngolepis, a Lower Devonian crossopterygian from Yunnan, south-western China' at Stockholm University. She was the first woman to become head of IVPP in 1983. For her many career achievements, she received an honorary degree from the University of Chicago in 2011 and the Romer-Simpson Medal from the Society of Vertebrate Paleontology in 2016.
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.
Dunhuangia is a bird genus, belonging to the Enantiornithes, which during the Early Cretaceous lived in the area of present China.
Juehuaornis is an extinct genus of ornithuromorph dinosaurs from the Early Cretaceous of present-day China. It contains a single species, J. zhangi.
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.
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.
