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. The genus name refers to the Daxia River, a tributary of the Yellow River that runs through the area where t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Titanosaurs
Titanosaurs (or titanosaurians; members of the group Titanosauria) were a diverse group of sauropod dinosaurs, including genera from all seven continents. The titanosaurs were the last surviving group of long-necked sauropods, with taxa still thriving at the time of the extinction event at the end of the Cretaceous. This group includes some of the largest land animals known to have ever existed, such as ''Patagotitan''—estimated at long with a weight of —and the comparably-sized ''Argentinosaurus'' and ''Puertasaurus'' from the same region. The group's name alludes to the mythological Titans of ancient Greek mythology, via the type genus (now considered a ''nomen dubium)'' '' Titanosaurus''. Together with the brachiosaurids and relatives, titanosaurs make up the larger sauropod clade Titanosauriformes. Titanosaurs have long been a poorly-known group, and the relationships between titanosaur species are still not well-understood. Description Titanosauria have the largest ...

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 ...

Euhelopodidae
Euhelopodidae is a family of sauropod dinosaurs of disputed membership and affinities, which contains ''Euhelopus'' and its close relatives. Most proposed euhelopodids are from East Asia. Euhelopodidae was first recognized by Carl Wiman in 1929, under the name Helopodidae, as ''Euhelopus'' was originally named ''Helopus''. However, the name had already been proposed for a bird, so in 1956 Alfred Sherwood Romer proposed the name ''Euhelopus'' and Euhelopodinae as replacements; Romer classified Euhelopodinae as a subfamily of Brachiosauridae, in which he also included Camarasaurinae and Cetiosaurinae, rather than as a family of its own. In addition to ''Euhelopus'' itself, Romer included ''Chiayusaurus'', ''Omeisaurus'', and ''Tienshanosaurus'' in Euhelopodinae. The taxonomic content of Euhelopodidae is uncertain, as a result of the unstable position of ''Euhelopus'' itself. Some studies have concluded that ''Euhelopus'' is a non-neosauropod closely related to ''Mamenchisaurus'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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''. Fossil eggs are rare, but one oogenus, ''Polyclonoolithus'', was discovered in the Hekou Group.Xie, J.-F., Zhang, S.-K., Jin, X.-S., Li, D.-Q., and Zhou, L.-Q.

Mamenchisaurids
Mamenchisauridae is a family of sauropod dinosaurs belonging to Eusauropoda known from the Jurassic and Early Cretaceous of Asia and Africa. Some members of the group reached gigantic sizes, amongst the largest of all sauropods. Classification The family Mamenchisauridae was first erected by Chinese paleontologists Yang Zhongjian ("C.C. Young") and Zhao Xijin in 1972, in a paper describing ''Mamenchisaurus hochuanensis''.Young, C.C. and Zhao, X. (1972). "''Mamenchisaurus hochuanensis sp. nov.''". ''Institute of Vertebrate Palaeontology and Palaeoanthropology Monographs'' Series A 8: 1-30. The most complete cladogram of Mamenchisauridae is presented by Moore ''et al.'', 2020, which includes several named species. Notably, some iterations of their analysis recover ''Euhelopus'' and kin, usually considered somphospondylians, as relatives of mamenchisaurids, mirroring earlier conceptions about the family.

Euhelopus
''Euhelopus'' is a genus of sauropod dinosaur that lived between 145 and 133 million years ago during the Berriasian and Valanginian stages of the Early Cretaceous in what is now Shandong Province in China. It was a large quadrupedal herbivore. Unlike most other sauropods, ''Euhelopus'' had longer forelegs than hind legs. This discovery was paleontologically significant because it represented the first dinosaur scientifically investigated from China: seen in 1913, rediscovered in 1922, and excavated in 1923 and studied by T'an during the same year.T'an, H. C. (1923). New research on the Mesozoic and early Tertiary geology in Shantung. Geological Survey of China Bulletin 5:95-135 Unlike most sauropod specimens, it has a relatively complete skull. ''Euhelopus'' was a long-necked sauropod similar to '' Mamenchisaurus'', but its affinities are controversial. Most studies favor a close relationship between ''Euhelopus'' and titanosaurs, rather than mamenchisaurids. Description Si ...

Bingling Temple
The Bingling Temple () is a series of grottoes filled with Buddhist sculpture carved into natural caves and caverns in a canyon along the Yellow River. It lies just north of where the Yellow River empties into the Liujiaxia Reservoir. Administratively, the site is in Yongjing County of Linxia Hui Autonomous Prefecture in Gansu province, some southeast of Lanzhou. This temple, along with other sites along the Silk Road, was inscribed in 2014 on the UNESCO World Heritage List as the Silk Roads: the Routes Network of Chang'an-Tianshan Corridor World Heritage Site. The caves were a work in progress for more than a millennium. The first grotto was begun around 420 CE at the end of the Western Qin kingdom. Work continued and more grottoes were added during the Wei, Sui, Tang, Song, Yuan, Ming, and Qing dynasties. The style of each grotto can easily be connected to the typical artwork from its corresponding dynasty. The Bingling Temple is both stylistically and geographically ...
