Napaisaurus guangxiensis Ji & Zhang, 2022 |
Napaisaurus is a genus of iguanodontian ornithopod dinosaur from the Early Cretaceous Xinlong Formation of Guangxi, China. The type and only species is N. guangxiensis. [1]
The Napaisaurus holotype, FS-20-007–008, consists of a right ilium and ischium discovered in 2020. A mix of diagonstic characters observed in the material led Ji & Zhang to describe it as a new genus and species in 2022. The generic name, "Napaisaurus", combines a reference to the type locality in the Napai Basin with the Greek word "saurus", meaning "lizard". The specific name, "guangxiensis", references Guangxi Zhuang Autonomous Region where the fossils were discovered. Napaisaurus represents the first basal iguanodontian to be named from southern China. [1]
Napaisaurus was mentioned in a review of fossil of ornithischians from Southeast Asia and southern China in 2023 by Manitkoon et al. They suggested that the Napaisaurus holotype should be compared to the undescribed ischium and ilium of Sirindhorna in future research. [2]
Enigmosaurus is a genus of therizinosauroid that lived in Asia during the Late Cretaceous period. It was a medium-sized, ground-dwelling, bipedal herbivore that represents the third therizinosaur taxon from the Bayan Shireh Formation, although it is known from the lower part. The genus is monotypic, including only the type species E. mongoliensis, known from a well preserved pelvis and other tentative body remains.
Camptosaurus is a genus of plant-eating, beaked ornithischian dinosaurs of the Late Jurassic period of western North America and possibly also Europe. The name means 'flexible lizard'.
Micropachycephalosaurus is an extinct genus of basal marginocephalian dinosaur containing only the type species, Micropachycephalosaurus hongtuyanensis. It lived in China during the Late Cretaceous (Campanian) and was found in the Jiangjunding Formation.
Qinlingosaurus is a genus of herbivorous sauropod dinosaur from the Late Cretaceous of Asia.
Stenopelix is a genus of small marginocephalian dinosaur, possibly a basal ceratopsian, from the Early Cretaceous of Germany. It lived in the late Berriasian Stage of the Cretaceous period, approximately 140 myr ago. The genus is based on a partial skeleton lacking the skull, and its classification is based on characteristics of the hips.
Fulgurotherium is a dubious genus of ornithischian dinosaur from the Late Cretaceous (Cenomanian) Griman Creek Formation. It lived in what is now Australia.
Cumnoria is a genus of herbivorous iguanodontian dinosaur. It was a basal iguanodontian that lived during the Late Jurassic period in what is now Oxfordshire, United Kingdom.
Nanshiungosaurus is a genus of therizinosaurid that lived in what is now Asia during the Late Cretaceous of South China. The type species, Nanshiungosaurus brevispinus, was first discovered in 1974 and described in 1979 by Dong Zhiming. It is represented by a single specimen preserving most of the cervical and dorsal vertebrae with the pelvis. A supposed and unlikely second species, "Nanshiungosaurus" bohlini, was found in 1992 and described in 1997. It is also represented by vertebrae but this species however, differs in geological age and lacks authentic characteristics compared to the type, making its affinity to the genus unsupported.
Nanyangosaurus is a genus of herbivorous ornithischian dinosaur belonging to Hadrosauroidea that lived in the Late Cretaceous of present-day Henan Province, China.
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.
Luanchuanraptor is a genus of dromaeosaurid theropod dinosaurs from the Late Cretaceous of China. The genus is based on a partial skeleton from the Qiupa Formation in Luanchuan, Henan. They were medium-sized dromaeosaurids, the first Asian dromaeosaurid taxa described from outside the Gobi Desert or northeastern China.
The Xinlong Formation is an Early Cretaceous geologic formation in Guangxi, southern China.
Hypselospinus is a genus of iguanodontian dinosaur which was first described as a species of Iguanodon by Richard Lydekker in 1889, the specific name honouring William Henry Fitton.
Barilium is a genus of iguanodontian dinosaur which was first described as a species of Iguanodon by Richard Lydekker in 1888, the specific epithet honouring the discoverer Charles Dawson, who collected the holotype during the 1880s.
Datanglong is an extinct genus of theropod belonging to either Carcharodontosauria or Megaraptora. It existed during the Early Cretaceous (Barremian-Albian) in what is now southeastern China.
Mosaiceratops is a genus of ceratopsian, described by Zheng, Jin & Xu in 2015 and found in the Xiaguan Formation of Neixiang County. Mosaiceratops lived in the upper Cretaceous in what is now the Henan Province of China.
Zuoyunlong is an extinct genus of herbivorous ornithischian dinosaur belonging to the Hadrosauroidea, that lived during the Late Cretaceous in the area of present China.
Sirindhorna is a genus of hadrosauroid ornithopod dinosaur from Early Cretaceous deposits of northeastern Thailand.
Sinankylosaurus is a genus of dinosaur, originally described as an ankylosaur, from the Late Cretaceous Hongtuya Formation of Shandong, China. The genus contains a single species, Sinankylosaurus zhuchengensis, known from a nearly complete right ilium. The describers claim that the discovery of Sinankylosaurus further demonstrates the similarity between dinosaurs of eastern Asia and western North America.
