Sinosaurus
''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 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shuangbaisaurus
''Shuangbaisaurus'' (meaning "Shuangbai reptile") is genus of theropod dinosaur, possibly a junior synonym of '' Sinosaurus.'' It lived in the Early Jurassic of Yunnan Province, China, and is represented by a single species, ''S. anlongbaoensis'', known from a partial skull. Like the theropods ''Dilophosaurus'' and ''Sinosaurus,'' ''Shuangbaisaurus'' bore a pair of thin, midline crests on its skull. Unusually, these crests extended backwards over the level of the eyes, which, along with the unusual orientation of the jugal bone, led the describers to name it as a new genus. However, ''Shuangbaisaurus'' also possesses a groove between its premaxilla and maxilla, a characteristic which has been used to characterize ''Sinosaurus'' as a genus. Among the two morphotypes present within the genus ''Sinosaurus'', ''Shuangbaisaurus'' more closely resembles the morphotype that is variably treated as a distinct species, ''S. sinensis'', in its relatively tall skull.

Dilophosaurus
''Dilophosaurus'' ( ) is a genus of theropod dinosaurs that lived in what is now North America during the Early Jurassic, about 193 million years ago. Three skeletons were discovered in northern Arizona in 1940, and the two best preserved were collected in 1942. The most complete specimen became the holotype of a new species in the genus ''Megalosaurus'', named ''M. wetherilli'' by Samuel P. Welles in 1954. Welles found a larger skeleton belonging to the same species in 1964. Realizing it bore crests on its skull, he assigned the species to the new genus ''Dilophosaurus'' in 1970, as ''Dilophosaurus wetherilli''. The genus name means "two-crested lizard", and the species name honors John Wetherill, a Navajo councilor. Further specimens have since been found, including an infant. Footprints have also been attributed to the animal, including resting traces. Another species, ''Dilophosaurus sinensis'' from China, was named in 1993, but was later found to belong to the g ...

Lufeng Formation
The Lufeng Formation (formerly Lower Lufeng Series) is a Lower Jurassic sedimentary rock formation found in Yunnan, China. It has two units: the lower Dull Purplish Beds/Shawan Member are of Hettangian age, and Dark Red Beds/Zhangjia'ao Member are of Sinemurian age.Luo, Z., and X.-C. Wu. 1994. The small tetrapods of the Lower Lufeng Formation, Yunnan, China; pp. 251–270 in N. C. Fraser and H.-D.Sues (eds.), In the Shadow of the Dinosaurs. Cambridge University Press, New York It is known for its fossils of early dinosaurs. The Dull Purplish Beds have yielded the possible therizinosaur '' Eshanosaurus'', the possible theropod ''Lukousaurus'', and the " prosauropods" "Gyposaurus" ''sinensis'', ''Lufengosaurus'', '' Jingshanosaurus'', and ''Yunnanosaurus''. Dinosaurs discovered in the Dark Red Beds include the theropod ''Sinosaurus triassicus'', the "prosauropods" "Gyposaurus", ''Lufengosaurus'', and ''Yunnanosaurus'', indeterminate remains of sauropods, and the early armored ...

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''. R ...

Maxilla
The maxilla (plural: ''maxillae'' ) in vertebrates is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth. The two maxillary bones are fused at the intermaxillary suture, forming the anterior nasal spine. This is similar to the mandible (lower jaw), which is also a fusion of two mandibular bones at the mandibular symphysis. The mandible is the movable part of the jaw. Structure In humans, the maxilla consists of: * The body of the maxilla * Four processes ** the zygomatic process ** the frontal process of maxilla ** the alveolar process ** the palatine process * three surfaces – anterior, posterior, medial * the Infraorbital foramen * the maxillary sinus * the incisive foramen Articulations Each maxilla articulates with nine bones: * two of the cranium: the frontal and ethmoid * seven of the face: the nasal, zygomatic, lacrimal ...

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) ...

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 p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.
