Euhelopodidae
Euhelopodidae is a family of sauropod dinosaur Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is t ...s 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 ''Tie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euhelopus Zdanskyi
''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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yongjinglong
''Yongjinglong'' is an extinct genus of titanosauriform sauropod dinosaur known from the Early Cretaceous of Lanzhou-Minhe Basin of Gansu Province, China. It contains a single species, ''Yongjinglong datangi''. Discovery ''Yongjinglong'' was first described and named by Li-Guo Li, Da-Qing Li, Hai-Lu You and Peter Dodson in 2014 and the type species is ''Yongjinglong datangi''. The generic name is derived from the name of the historical Yongjing County, near where the holotype of ''Yongjinglong'' and numerous dinosaur track fossils were collected, and from ''long'', meaning " dragon" in Chinese. The specific name, ''datangi'', honors the Tang dynasty and also Mr. Zhi-Lu Tang from the IVPP, for his contributions to the study of dinosaurs. ''Yongjinglong'' is known solely from the holotype GSGM ZH(08)-04, a partial postcranial skeleton and three teeth, currently housed at the Gansu Geological Museum, Gansu Province.

Mamenchisauridae
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.

Macronarians
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 sever ...

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.

Neosauropoda
Neosauropoda is a clade within Dinosauria, coined in 1986 by Argentine paleontologist José Bonaparte and currently described as ''Saltasaurus loricatus'', ''Diplodocus longus'', and all animals directly descended from their most recent common ancestor. The group is composed of two subgroups: Diplodocoidea and Macronaria. Arising in the early Jurassic and persisting until the Cretaceous-Paleogene extinction event, Neosauropoda contains the majority of sauropod genera, including genera such as ''Apatosaurus'', ''Brachiosaurus'', and ''Diplodocus''. It also includes giants such as '' Argentinosaurus'', '' Patagotitan'' and '' Sauroposeidon'', and its members remain the largest land animals ever to have lived. When Bonaparte first coined the term Neosauropoda in 1986, he described the clade as comprising “end-Jurassic” sauropods. While Neosauropoda does appear to have originated at the end of the Jurassic period, it also includes members throughout the Cretaceous. Neosaurop ...

Dinosaur
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Dinosaurs are varied from taxonomic, morphological and ecological standpoints. Birds, at over 10,700 living species, ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phuwiangosaurus
''Phuwiangosaurus'' (meaning "Phu Wiang lizard") is a genus of titanosaur dinosaur from the Early Cretaceous (Valanginian-Hauterivian) Sao Khua Formation of Thailand. The type species, ''P. sirindhornae'', was described by Martin, Buffetaut, and Suteethorn in a 1993 press release and was formally named in 1994. The species was named to honor Princess Maha Chakri Sirindhorn of Thailand, who was interested in the geology and palaeontology of Thailand, while the genus was named after the Phu Wiang area, where the fossil was discovered. In 2010 Paul gave a length of 19 meters (62 ft) and a weight of 17 tonnes (18.7 short tons). In 2012 Holtz gave a higher estimation of 25 meters (82 ft). ''Phuwiangosaurus'' was originally assigned to Titanosauria, but more recent studies have placed it in a more basal position within the Titanosauriformes. Phylogenetic analyses presented by D'Emic (2012), Mannion ''et al.'' (2013), and Mocho ''et al.'' (2014) resolve ''Phuwiangosaurus'' within ...

Tangvayosaurus
''Tangvayosaurus'' (meaning "Tang Vay lizard") is a genus of sauropod dinosaur from the Aptian-Albian age Lower Cretaceous Gres superieurs Formation of Savannakhet Province, Laos. It was a basal somphospondylan, about 15 m long, and is known from the remains of two or three individuals. Description It is based on TV4-1 to TV4-36, consisting of a partial pelvis, several back vertebrae and a tail vertebra, ribs, and an upper arm bone ( humerus). Another skeleton includes 38 tail vertebrae, a neck vertebra, and most of a hind limb. The type species, ''Tangvayosaurus hoffeti'', was described by a group of a dozen scientists led by Ronan Allain in 1999 and the species name honours French palaeontologist Joshua Hoffet (1901-disappeared 1945). Allain ''et al.'' also referred the old species ''"Titanosaurus" falloti'' (Hoffet, 1942),J.-H. Hoffet. (1942).

Neuquensaurus
''Neuquensaurus'' (meaning "Neuquén lizard") is a genus of saltasaurid sauropod dinosaur that lived in the Late Cretaceous, about 80 million years ago in Argentina and Uruguay in South America. Its fossils were recovered from outcrops of the Anacleto Formation around Cinco Saltos, near the Neuquén river from which its name is derived. History In 1893, Richard Lydekker named ''Titanosaurus australis'', based on a series of caudal vertebrae and limb elements. The remains had been found by Santiago Roth and F. Romero in the Neuquén Province of Argentina at the Neuquén River, and were by Lydekker assigned to a single individual. Six caudal vertebrae, with the inventory numbers MLP Ly 1-6-V-28-1, were the holotype of the species. They had probably been found in a layer of the Anacleto Formation. Some elements that had been referred to ''Titanosaurus australis'' were reassigned to '' Laplatasaurus araukanicus'' by Friedrich von Huene in 1929. The same year, von Huene named a ''Ti ...
