Adeopapposaurus Scale
''Adeopapposaurus'' (meaning "far eating lizard", in reference to its long neck) is a genus of Plateosauria, plateosaurian dinosaur from the Early Jurassic Cañón del Colorado Formation of San Juan, Argentina, San Juan, Argentina. It was similar to ''Massospondylus''. Four partial skeletons with two partial skulls are known. The holotype, type specimen, Instituto y Museo de Ciencias Naturales, PVSJ568, includes a skull and most of a skeleton to just past the hips. The form of the bones at the tips of the upper and lower jaws suggests it had keratinous beaks. The fossils now named ''Adeopapposaurus'' were first thought to represent South American examples of ''Massospondylus''; while this is no longer the case, ''Adeopapposaurus'' is classified as a massospondylidae, massospondylid. ''Adeopapposaurus'' was described in 2009 by Ricardo N. Martínez. The type species is ''A. mognai'', referring to the Mogna locality where it was found. The found fossils of ''Adeopapposaurus'' have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Jurassic
The Early Jurassic Epoch (geology), Epoch (in chronostratigraphy corresponding to the Lower Jurassic series (stratigraphy), Series) is the earliest of three epochs of the Jurassic Period. The Early Jurassic starts immediately after the Triassic–Jurassic extinction event, 201.3 Ma (million years ago), and ends at the start of the Middle Jurassic 174.7 ±0.8 Ma. Certain rocks of marine origin of this age in Europe are called "Lias Group, Lias" and that name was used for the period, as well, in 19th-century geology. In southern Germany rocks of this age are called Black Jurassic. Origin of the name Lias There are two possible origins for the name Lias: the first reason is it was taken by a geologist from an England, English quarryman's dialect pronunciation of the word "layers"; secondly, sloops from north Cornwall, Cornish ports such as Bude would sail across the Bristol Channel to the Vale of Glamorgan to load up with rock from coastal limestone quarries (lias and Carbonif ...

Glacialisaurus2
''Glacialisaurus'' is a genus of sauropodomorph dinosaur from the Early Jurassic period (geology), period of Antarctica. It is known from two specimens; the holotype (name-bearing specimen), a partial Tarsus (skeleton), tarsus (ankle) and Metatarsal bones, metatarsus, and a partial left femur (upper thigh bone). The fossils were collected by a team led by paleontologist William R. Hammer during a 1990–91 field expedition to the central region of the Transantarctic Mountains. They come from sedimentary rocks of the Hanson Formation and date to the Pliensbachian stage of the Early Jurassic, around 186 to 182 million years ago. The fossils were described in 2007, and made the basis of the new genus and species ''Glacialisaurus hammeri''. The genus name translates as “icy” or "frozen lizard”, and the specific name honors Hammer. This dinosaur has been classified as a Massospondylidae, massospondylid, a group of medium-sized, Basal (phylogenetics), basal (early diverging or " ...

Coloradisaurus
''Coloradisaurus'' (meaning "Los Colorados lizard") is a genus of massospondylid sauropodomorph dinosaur. It lived during the Late Triassic period (Norian stage) in what is now La Rioja Province, Argentina. It is known from two specimens collected from the Los Colorados Formation of the Ischigualasto-Villa Unión Basin. Taxonomy ''Coloradisaurus brevis'' was originally named ''Coloradia brevis'' by José Bonaparte in 1978, but that genus name was preoccupied by the pine moth '' Coloradia'', so it needed a replacement name. In 1983, David Lambert used the name ''Coloradisaurus'' for the genus, but did not indicate it was a replacement or diagnose it. Lambert had gotten the name from Bonaparte in a personal communication and mistakenly thought that Bonaparte had already published it. Peter Galton was the next to use the name ''Coloradisaurus'' in 1990, which he credited to Lambert, when he gave the taxon a diagnosis in his review of prosauropods in ''The Dinosauria''. Author ...

Seitaad
''Seitaad'' is a genus of sauropodomorph dinosaur which lived during the Early Jurassic period in what is now southern Utah, United States. ''Seitaad'' is known from an articulated partial postcranial holotype skeleton referred to as UMNH VP 18040. The skeleton is missing its head, neck and tail. It was collected from the Lower Jurassic Navajo Sandstone, the uppermost unit of the Glen Canyon Group, dating to the Pliensbachian stage, near Comb Ridge, San Juan County. A phylogenetic study of ''Seitaad'' found it to be a plateosaur sauropodomorph, placing it in Massospondylidae or alternatively (a less probable position) in Plateosauridae, but its placement within the Plateosauria is not well understood. In a cladistic analysis, presented by Apaldetti and colleagues in November 2011, ''Seitaad'' was found to be within Massopoda, just outside Anchisauria. ''Seitaad'' was first described by Joseph J. W. Sertich and Mark A. Loewen in 2010 and the type species is ''Seitaad ruessi''. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jingshanosaurus Xinwaensis
''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. First described in 1995, the type species is ''J. xinwaensis'', formalized by Zhang and Yang.Y. Zhang, and Z. Yang. (1995).

Yunnanosaurus
''Yunnanosaurus'' ( ) is an extinct genus of sauropodomorph dinosaur that lived approximately 199 to 183 million years ago in what is now the Yunnan Province, in China, for which it was named. ''Yunnanosaurus'' was a large sized, moderately-built, ground-dwelling, quadrupedal herbivore, that could also walk bipedally, and ranged in size from 7 meters (23 feet) long and 2 m (6.5 ft) high to 4 m (13 ft) high in the largest species. Discovery Yang Zhongjian (also known as C. C. Young) discovered the first ''Yunnanosaurus'' skeletons in the upper Zhangjiawa Member of the Lufeng Formation of Yunnan, People's Republic of China, China, dating to the Sinemurian stage of the Early Jurassic. The fossil find was composed of over twenty incomplete skeletons, including two skulls, it was excavated by Tsun Yi Wang. These remains were the basis for the species ''Y. huangi'' (the type species) and ''Y. robustus.'' In 2007, Lü Junchang and colleagues described an ...

Massospondylidae
Massospondylidae is a family (biology), family of early massopod dinosaurs that existed in Asia, Africa, North America, South America and AntarcticaHellert, Spencer M. "A New Basal Sauropodomorph from The Early Jurassic Hanson Formation of Antarctica." Geological Society of America Abstracts with Programs,. Vol. 44. No. 5. 2012. during the Late Triassic to the Early Jurassic periods. Several dinosaurs have been classified as massospondylids over the years. The largest cladistic analysis of early sauropodomorphs, which was presented by Apaldetti and colleagues in November 2011, found ''Adeopapposaurus'', ''Coloradisaurus'', ''Glacialisaurus'', ''Massospondylus'', ''Leyesaurus'' and ''Lufengosaurus'' to be massospondylids. This result supports many previous analyses that tested fewer taxa. However, this analysis found the two recently described North American massopods, ''Sarahsaurus'' and ''Seitaad'', and the South African ''Ignavusaurus'' to nest outside Massospondylidae, as oppos ...

Sarahsaurus
''Sarahsaurus'' is a genus of basal (phylogenetics), basal sauropodomorph dinosaur which lived during the Early Jurassic period in what is now northeastern Arizona, United States. Discovery and naming All specimens of ''Sarahsaurus'' were collected from the Lower Jurassic Kayenta Formation near Gold Spring, Arizona. The genus is based on a nearly complete and articulated (with bones still connected to each other) skeleton with a fragmentary and disarticulated skull (holotype, specimen number TMM 43646-2). In addition, a partial skeleton (specimen number TMM 43646-3) as well as a nearly complete skull (specimen number Harvard Museum of Comparative Zoology, MCZ 8893) was assigned to the genus. The latter specimen was originally referred to as ''Massospondylus'' sp. The complete skull is crushed and split horizontally, separating the skull roof from the palate; this split was caused by periodic swelling and shrinkage of the surrounding clay after deposition (geology), burial.
