Sinosaurus Triassicus
''Sinosaurus'' (meaning "Chinese lizard") is an extinct genus of theropod dinosaur which lived during the Early Jurassic Period. It was a bipedal carnivore approximately in length and in body mass. Fossils of the animal were found at the Lufeng Formation, in the Yunnan Province of China. Discovery and naming The composite term ''Sinosaurus'' comes from ''Sinae'', the Latin word for the Chinese, and the Greek word ' () meaning "lizard"; thus "Chinese lizard". The specific name, ''triassicus'', refers to the Triassic, the period that the fossils were originally thought to date from. ''Sinosaurus'' was described and named by Chung Chien Young, who is known as the 'Father of Chinese Vertebrate Paleontology', in 1940. The holotype, IVPP V34, was found in the Lower Lufeng Formation, and consists of two maxillary (upper jaw) fragments, four maxillary teeth, and a lower jaw fragment with three teeth. The teeth are laterally compressed, and feature fine serrations both at their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coelophysis Kayentakatae
''Coelophysis''? ''kayentakatae'' is an extinct species of neotheropod dinosaur that lived approximately 200 - 196 million years ago during the early part of the Jurassic Period in what is now the southwestern United States. While originally assigned to the genus '' Syntarsus'' as ''Syntarsus kayentakatae'', that genus name was found to be preoccupied by a Colydiine beetle, so it was moved to the genus ''Megapnosaurus'' as ''Megapnosaurus kayentakatae''. Later it was moved again to ''Coelophysis'', however the species still possesses no definite genus assignment. Discovery The holotype of ''C.''? ''kayentakatae'' (MNA V2623) was recovered in the Silty Facies Member of the Kayenta Formation in Arizona. This material was collected in 1977 from carbonaceous sandstone deposited during the Sinemurian and Pliensbachian stages of the Jurassic period.Padian, K (1997) Glen Canyon Group In: Encyclopedia of Dinosaurs, edited by Currie, P.

Zupaysaurus
''Zupaysaurus'' (; "ZOO-pay-SAWR-us") is an extinct genus of early theropod dinosaur living during the Norian stage of the Late Triassic in what is now Argentina. Fossils of the dinosaur were found in the Los Colorados Formation of the Ischigualasto-Villa Unión Basin in northwestern Argentina. Although a full skeleton has not yet been discovered, ''Zupaysaurus'' can be considered a bipedal predator, up to long. It may have had two parallel crests running the length of its snout. Discovery Discovered in May 1997 by Santiago Reuil ("Vultur"), part of the crew of Guillermo Rougier, it was later described by Arcucci and Coria and published in 2003. The name ''Zupaysaurus'' is composed of the Quechua word ''supay'' meaning "devil" and the Greek word ' () meaning "lizard"; thus "devil lizard". In Incan mythology, ''supay'' was both the god of death and ruler of the '' ukhu pacha'', the Incan underworld. The type species was named ''Z. rougieri'' in the honor of Guillermo Rougier ...

Premaxilla
The premaxilla (or praemaxilla) is one of a pair of small cranial bones at the very tip of the upper jaw of many animals, usually, but not always, bearing teeth. In humans, they are fused with the maxilla. The "premaxilla" of therian mammal has been usually termed as the incisive bone. Other terms used for this structure include premaxillary bone or ''os premaxillare'', intermaxillary bone or ''os intermaxillare'', and Goethe's bone. Human anatomy In human anatomy, the premaxilla is referred to as the incisive bone (') and is the part of the maxilla which bears the incisor teeth, and encompasses the anterior nasal spine and alar region. In the nasal cavity, the premaxillary element projects higher than the maxillary element behind. The palatal portion of the premaxilla is a bony plate with a generally transverse orientation. The incisive foramen is bound anteriorly and laterally by the premaxilla and posteriorly by the palatine process of the maxilla. It is formed from the ...

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 of ...

Jingshanosaurus
''Jingshanosaurus'' (meaning "Jingshan lizard") is a genus of sauropodomorph dinosaurs from the early Jurassic period 201.3 million years ago that went extinct 199.3 million years ago in the Hettangian Age. Its maximum weight was around 4.3 t with an adult femur length of 845 mm. ''Jingshanosaurus xinwaensis'' grew to be 5 meters (16.4 ft) long. History of discovery Its fossils, a nearly complete skeleton including the skull, were found near the town of Jingshan ("Golden Hill"), Lufeng County, Yunnan Province, China, from which the name derives.

Melanorosauridae
The Melanorosauridae were a family of sauropodomorph dinosaurs which lived during the Late Triassic and Early Jurassic. The name Melanorosauridae was first coined by Friedrich von Huene in 1929. Huene assigned several families of dinosaurs to the infraorder "Prosauropoda": the Anchisauridae, the Plateosauridae, the Thecodontosauridae, and the Melanorosauridae. Since then, these families have undergone numerous revisions. Galton and Upchurch (2004) considered '' Camelotia'', ''Lessemsaurus'', and '' Melanorosaurus'' members of the family Melanorosauridae. A more recent study by Yates (2007) indicates that the melanorosaurids were instead early sauropod Sauropoda (), whose members are known as sauropods (; from '' sauro-'' + '' -pod'', 'lizard-footed'), is a clade of saurischian ('lizard-hipped') dinosaurs.

Plateosauridae
Plateosauridae is a family of plateosaurian sauropodomorphs from the Late Triassic of Europe, Greenland, Africa and Asia. Although several dinosaurs have been classified as plateosaurids over the years, the family Plateosauridae is now restricted to ''Plateosaurus'', ''Yimenosaurus'', ''Euskelosaurus'', and ''Issi''''.'' In another study, Yates (2003) sunk ''Sellosaurus'' into ''Plateosaurus'' (as ''P. gracilis''). Classification Plateosauridae, which was first named by Othniel Charles Marsh in 1895, is a stem-based taxon and it was defined by Sereno, 1998 as all animals more closely related to ''Plateosaurus engelhardti'' than to ''Massospondylus carinatus''. Galton and Upchurch, 2004 proposed the following definition: all animals more closely related to ''Plateosaurus engelhardti'' than to ''Massospondylus carinatus'' and ''Yunnanosaurus huangi''. Yates, 2007 defined it as all animals more closely related to ''Plateosaurus engelhardti'' than to ''Diplodocus longus''. Recent cla ...

Sacrum
The sacrum (plural: ''sacra'' or ''sacrums''), in human anatomy, is a large, triangular bone at the base of the spine that forms by the fusing of the sacral vertebrae (S1S5) between ages 18 and 30. The sacrum situates at the upper, back part of the pelvic cavity, between the two wings of the pelvis. It forms joints with four other bones. The two projections at the sides of the sacrum are called the alae (wings), and articulate with the ilium at the L-shaped sacroiliac joints. The upper part of the sacrum connects with the last lumbar vertebra (L5), and its lower part with the coccyx (tailbone) via the sacral and coccygeal cornua. The sacrum has three different surfaces which are shaped to accommodate surrounding pelvic structures. Overall it is concave (curved upon itself). The base of the sacrum, the broadest and uppermost part, is tilted forward as the sacral promontory internally. The central part is curved outward toward the posterior, allowing greater room for the pel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sauropodomorpha
Sauropodomorpha ( ; from Greek, meaning "lizard-footed forms") is an extinct clade of long-necked, herbivorous, saurischian dinosaurs that includes the sauropods and their ancestral relatives. Sauropods generally grew to very large sizes, had long necks and tails, were quadrupedal, and became the largest animals to ever walk the Earth. The '' prosauropods,'' which preceded the sauropods, were smaller and were often able to walk on two legs. The sauropodomorphs were the dominant terrestrial herbivores throughout much of the Mesozoic Era, from their origins in the Late Triassic (approximately 230 Ma) until their decline and extinction at the end of the Cretaceous. Description Sauropodomorphs were adapted to browsing higher than any other contemporary herbivore, giving them access to high tree foliage. This feeding strategy is supported by many of their defining characteristics, such as: a light, tiny skull on the end of a long neck (with ten or more elongated cervical vertebrae) ...
