Huanghetitan
''Huanghetitan'' (meaning "Yellow River titan"), is a genus of sauropod dinosaur from the early Cretaceous Period. It was a basal titanosauriform which lived in what is now Gansu, China. History The type species, ''Huanghetitan liujiaxiaensis'', was described by You ''et al.'' in 2006. It is known from fragmentary materials including two caudal vertebrae, an almost complete sacrum, rib fragments, and the left shoulder girdle, and was discovered in the eastern part of the Lanzhou Basin (Hekou Group) in the Gansu Province in 2004. A second species, ''H. ruyangensis'', was described in 2007 from the Aptian-Albian Haoling Formation of Ruyang County, China (Henan Province). A recent cladistic analysis has found that this species is unlikely to be closely related to ''H. liujiaxiaensis'' and requires a new genus name. Description ''H. liujiaxiaensis'' is a relatively small sauropod, measuring long and weighing . ''H. ruyangensis'' is known from a partial vertebral column and ...

Ruyangosaurus
''Ruyangosaurus'' (Ruyang County lizard) is a genus of titanosauriform sauropod dinosaur recovered from the Early Cretaceous Haoling Formation of China. The type species is ''R. giganteus'', described in 2009 by Lü Junchang ''et al''. Description Along with ''Huanghetitan'' and ''Daxiatitan'', ''Ruyangosaurus'' is among the largest dinosaurs discovered in Cretaceous Asia. In 2016 Gregory S. Paul gave a length of 30 meters (100 ft) and a weight of 50+ tonnes (55 short tons) - making it a 'mega-sauropod'. ''Ruyangosaurus'' was probably about 35 meters (115 ft) long, as evidenced by its 207 cm long femur and 127 cm long right tibia. Classification The describers of ''Ruyangosaurus'' assigned it to Andesauridae. However, Andesauridae is not monophyletic and, as such, is no longer used. Comprehensive phylogenetic analyses of Titanosauriformes conducted by Philip Mannion and colleagues in 2013 found ''Ruyangosaurus'' to be in a polytomy with ''Andesaurus'' and other basal ...

Haoling Formation
The Haoling Formation is a Mesozoic geologic formation in the Ruyang Basin of Henan, Province, central China. Dinosaur remains are among the fossils that have been recovered from the formation. The Haoling Formation was originally treated as part of the Mangchuan Formation and considered to be of Paleocene age before being recognized as Mesozoic in age. A 2012 paper divided the Mangchuan into the Xiahedong, Haoling, and Shangdonggou Formations, assigning the dinosaur-bearing horizon to the Haoling Formation and constraining the age of the Haoling as Aptian-Albian based on fieldwork and invertebrate and microfossil assemblages.

Sauropod
Sauropoda (), whose members are known as sauropods (; from '' sauro-'' + '' -pod'', 'lizard-footed'), is a clade of saurischian ('lizard-hipped') dinosaurs. Sauropods had very long necks, long tails, small heads (relative to the rest of their body), and four thick, pillar-like legs. They are notable for the enormous sizes attained by some species, and the group includes the largest animals to have ever lived on land. Well-known genera include ''Brachiosaurus'', ''Diplodocus'', ''Apatosaurus'' and ''Brontosaurus''. The oldest known unequivocal sauropod dinosaurs are known from the Early Jurassic. ''Isanosaurus'' and ''Antetonitrus'' were originally described as Triassic sauropods, but their age, and in the case of ''Antetonitrus'' also its sauropod status, were subsequently questioned. Sauropod-like sauropodomorph tracks from the Fleming Fjord Formation (Greenland) might, however, indicate the occurrence of the group in the Late Triassic. By the Late Jurassic (150 million yea ...

Dongbeititan
''Dongbeititan'' is a genus of sauropod dinosaur from the Early Cretaceous-age Yixian Formation of Beipiao, Liaoning, China. It is based on holotype DNHM D2867, a partial postcranial skeleton including bones from the limbs, shoulder and pelvic girdles, and vertebrae, which was described in 2007. Its describers suggested it was as a basal titanosauriform, not as derived as ''Gobititan'' or ''Jiutaisaurus'', but more derived than ''Euhelopus'', ''Fusuisaurus'', and ''Huanghetitan''. The type species is ''D. dongi'', and it is the first named sauropod from the Yixian Formation, which is part of the well-known Jehol Group. The genus name refers to the region Dongbei and to Greek titan, "giant". The specific name honours the Chinese paleontologist Dong Zhiming. Like other sauropods, ''Dongbeititan'' would have been a large quadrupedal herbivore A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for ...

Titanosauriformes
Macronaria is a clade of sauropod dinosaurs. Macronarians are named after the large diameter of the nasal opening of their skull, known as the external naris, which exceeded the size of the orbit, the skull opening where the eye is located (hence ''macro''- meaning large, and –''naria'' meaning nose). Fossil evidence suggests that macronarian dinosaurs lived from the Middle Jurassic (Bathonian) through the Late Cretaceous (Maastrichtian). Macronarians have been found globally, including discoveries in Argentina, the United States, Portugal, China, and Tanzania. Like other sauropods, they are known to have inhabited primarily terrestrial areas, and little evidence exists to suggest that they spent much time in coastal environments. Macronarians are diagnosed through their distinct characters on their skulls, as well as appendicular and vertebral characters. Macronaria is composed of several subclades and families notably including Camarasauridae and Titanosauriformes, among severa ...

Daxiatitan
''Daxiatitan'' (; meaning "Daxia giant" after a tributary of the Yellow River) is a genus of sauropod dinosaur known from the Lower Cretaceous of Gansu, China. Its type and only species is ''Daxiatitan binglingi'' (). It is known from a single partial skeleton consisting of most of the neck and back vertebrae, two tail vertebrae, a shoulder blade, and a thigh bone. At the time of its discovery in 2008, ''Daxiatitan'' was regarded as potentially the largest known dinosaur from China. Taxonomy ''Daxiatitan'' and its type and only species ''Daxiatitan binglingi'' were named by You Hailu, Li Daqing, Zhou Lingqi, and Ji Qiang in 2008. The holotype of ''D. binglingi'', GSLTZP03-001, was collected from the Hekou Group, in Gansu Province, and consists of ten cervical, ten dorsal, and two caudal vertebrae, cervical and dorsal ribs, a haemal arch, a scapulocoracoid, and a femur.

Hekou Group
The Hekou Group is a geological group in Gansu Province, China. It is Early Cretaceous in age. Dinosaur body fossils have also been recovered from the Hekou Group, including the iguanodont '' Lanzhousaurus'' and the titanosaurs ''Daxiatitan'', ''Huanghetitan'' and '' Yongjinglong,'' and the nodosaur ''Taohelong''.

Pelorosaurus
''Pelorosaurus'' ( ; meaning "monstrous lizard") is a genus of titanosauriform sauropod dinosaur. Remains referred to ''Pelorosaurus'' date from the Early Cretaceous period, about 140-125 million years ago, and have been found in England and Portugal. Thomas Holtz estimated its length at 24 meters (79 feet). The name ''Pelorosaurus'' was one of the first to be given to any sauropod. Many species have been assigned to the genus historically, but most are currently considered to belong to other genera. Problematically, the first named species of ''Pelorosaurus'', ''P.conybeari'', is a junior synonym of ''Cetiosaurus brevis''. History ''Pelorosaurus'' was the first sauropod to be identified as a dinosaur, although it was not the first to be discovered. Richard Owen had discovered ''Cetiosaurus'' in 1841 but had incorrectly identified it as a gigantic sea-going crocodile-like reptile. Mantell identified ''Pelorosaurus'' as a dinosaur, living on land. The taxonomic history of ''Pelo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liubangosaurus
''Liubangosaurus'' (meaning "Liubang lizard", after the name of the holotype locality) is a genus of sauropod dinosaur that lived during the Early Cretaceous in what is now China. The type and only species is ''Liubangosaurus hei'', first described by Mo Jinyou, Xu Xing and Eric Buffetaut in 2010. ''Liubangosaurus'' is known from the holotype NHMG8152, five nearly complete and articulated middle-caudal dorsal vertebrae that were collected from the Xinlong Formation in Fusui County, Guangxi Province. Jinyou ''et al.'' (2010) found that ''Liubangosaurus'' belonged to the clade Eusauropoda. A 2013 comprehensive analysis of basal titanosauriforms found ''Liubangosaurus'' to nest in the Somphospondyli, either in Euhelopodidae or Saltasauridae Saltasauridae (named after the Salta region of Argentina where they were first found) is a family of armored herbivorous sauropods from the Upper Cretaceous.
