Sinraptor
''Sinraptor'' is a genus of metriacanthosaurid theropod dinosaur from the Late Jurassic. The name ''Sinraptor'' comes from the Latin prefix "Sino", meaning Chinese, and "raptor" meaning robber. The specific name ''dongi'' honours Dong Zhiming. Despite its name, ''Sinraptor'' is not related to dromaeosaurids (often nicknamed "raptors") like ''Velociraptor''. Instead, it was a carnosaur distantly related to ''Allosaurus''. ''Sinraptor'' and its close relatives were among the earliest members of the Jurassic carnosaurian radiation. ''Sinraptor'' still remains the best-known member of the family Metriacanthosauridae, with some older sources even using the name "Sinraptoridae" for the family. Discovery The holotype specimen of ''Sinraptor'' was uncovered from the Shishugou Formation during a joint Chinese/Canadian expedition to the northwestern Chinese desert in 1987, and described by Philip J. Currie and Zhao Xijin in 1993. Standing nearly tall and measuring roughly in length, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metriacanthosauridae
Metriacanthosauridae is an extinct family of allosauroid theropod dinosaurs that lived from the Middle Jurassic to the Early Cretaceous. When broken down into its Greek roots, it means "moderately-spined lizards". The family is split into two subgroups: Metriacanthosaurinae, which includes dinosaurs closely related to ''Metriacanthosaurus'', and another group composed of the close relatives of ''Yangchuanosaurus''. Metriacanthosaurids are considered carnosaurs, belonging to the Allosauroidea superfamily. The group includes species of large range in body size. Of their physical traits, most notable are their neural spines.Bailey, Jack Bowman. "Neural Spine Elongation in Dinosaurs: Sailbacks or Buffalo-Backs?" Journal of Paleontology, vol. 71, no. 06, 1997, pp. 1124–1146., doi:10.1017/s0022336000036076. The records of the group are mostly confined to Asia, though ''Metriacanthosaurus'' is known from Europe. Metriacanthosauridae is used as a senior synonym of Sinraptoridae. Diag ...

Yangchuanosaurus
''Yangchuanosaurus'' is an extinct genus of metriacanthosaurid theropod dinosaur that lived in China from the Middle to Late Jurassic periods (Bathonian to Oxfordian stages), and was similar in size and appearance to its North American and European relative, ''Allosaurus''. ''Yangchuanosaurus'' hails from the Upper Shaximiao Formation and was the largest predator in a landscape that included the sauropods ''Mamenchisaurus'' and '' Omeisaurus'' and the stegosaurs ''Chialingosaurus'', ''Tuojiangosaurus'' and ''Chungkingosaurus''. This theropod was named after the area in which was discovered, Yongchuan, in China. Discovery and species Dong ''et al.'' (1978) named ''Yangchuanosaurus shangyouensis'' on the basis of CV 00215, a complete skull and skeleton which was collected from the Shangshaximiao Formation, near Yongchuan, Yongchuan District, Sichuan. It dates to the Oxfordian stage of the Late Jurassic period, about 161.2 to 157.3 million years ago. It was disco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dong Zhiming
Dong Zhiming ( Chinese: 董枝明, Pinyin: ''Dǒng Zhimíng''; born January 1937) is a Chinese vertebrate paleontologist formerly employed at the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) in Beijing. He began working at the IVPP in 1962, studying under Yang Zhongjian, who was director at the time. He has described fossil remains of many dinosaurs. He investigated and described the Shaximiao Formation; an important contribution to science since they are composed of Middle Jurassic beds which do not commonly yield fossils. Early life and education Dong Zhiming was born in January 1937 in Weihai, Shandong. At the age of 13, Dong was introduced to dinosaurs by a museum exhibit showcasing hadrosaur fossils. Dong graduated from university in 1962 with a degree in biology. Career After graduating, Dong Zhiming began working at the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) in Beijing where he was mentored by Yang Zhongjian, the "father ...

Shishugou Formation
The Shishugou Formation () is a geological formation in Xinjiang, China. Its strata date back to the Late Jurassic period. Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel, David B; et al. (2004). "Dinosaur distribution (Late Jurassic, Asia)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 550–552. . The Shishugou Formation is considered one of the most phylogenetically and trophically diverse Middle to Late Jurassic theropod fauna.

Zigong
Zigong (, ), formed by the merger of the two former towns of Ziliujing (Tzuliuching, literally "self-flow well") and Gongjing (Kungching, literally "offering well"), is a prefecture-level city in Sichuan, southwestern China. Demographics According to the 2020 Chinese census, the prefecture-level city of Zigong has a population of 2,489,256 inhabitants, less than its population in 2010 (the average annual population growth for the period 2010–2020 was of -0.73%). However, the built-up (''or metro'') area, consisting of the 4 urban districts, grew, with 1,297,695 inhabitants (1,262,064 in 2010). History The area of Zigong has a long history in ancient China - with the invention and development of "Percussion Drilling rig" being one of the city's accomplishments. There are essentially two cities - that of the old and the new. The city was reached by rail in the 1950s. Several four-lane highways reach the city from other cities in the Sichuan province.

Allosaurus
''Allosaurus'' () is a genus of large carnosaurian theropod dinosaur that lived 155 to 145 million years ago during the Late Jurassic epoch ( Kimmeridgian to late Tithonian). The name "''Allosaurus''" means "different lizard" alluding to its unique (at the time of its discovery) concave vertebrae. It is derived from the Greek (') ("different, other") and (') ("lizard / generic reptile"). The first fossil remains that could definitively be ascribed to this genus were described in 1877 by paleontologist Othniel Charles Marsh. As one of the first well-known theropod dinosaurs, it has long attracted attention outside of paleontological circles. ''Allosaurus'' was a large bipedal predator. Its skull was light, robust and equipped with dozens of sharp, serrated teeth. It averaged in length for ''A. fragilis'', with the largest specimens estimated as being long. Relative to the large and powerful hindlimbs, its three-fingered forelimbs were small, and the body was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Tyrrell Museum
The Royal Tyrrell Museum of Palaeontology (RTMP, and often referred to as the Royal Tyrrell Museum) is a palaeontology museum and research facility in Drumheller, Alberta, Canada. The museum was named in honour of Joseph Burr Tyrrell, and is situated within a designed by BCW Architects at Midland Provincial Park. Efforts to establish a palaeontology museum were announced by the provincial government in 1981, with the palaeontology program of the Provincial Museum of Alberta spun-off to help facilitate the creation of a palaeontology museum. After four years of preparation, the Tyrrell Museum of Palaeontology was opened in September 1985. The museum was later renamed the Royal Tyrrell Museum of Palaeontology in June 1990, following its bestowal of the title "royal" from Queen Elizabeth II. The museum's building was expanded twice in the 21st century. The first expansion was designed by BCW Architects, and was completed in 2003; while the second expansion was designed by Kasian Ar ...
