Yuzhoulong
''Yuzhoulong'' (meaning "Chongqing dragon", after ''Yuzhou'', an early name for Chongqing) is a genus of macronarian sauropod dinosaur from the Middle Jurassic Shaximiao Formation of Chongqing, China. The type and only species is ''Yuzhoulong qurenensis''. Discovery and naming After the discovery of a new quarry from the Shaximiao Formation in 2016, the holotype of ''Yuzhoulong'', CLGRP V00013, was discovered in Pu'an town in Yunyang County in Chongqing. It was named as a distinct genus and species by Dai ''et al''. in 2022. The generic name, "''Yuzhoulong''", honors "Yuzhou", the ancient name of Chongqing, while the specific name, "''qurenensis''", is derived from Quren, the ancient name of Yunyang. Description ''Yuzhoulong'' is only known from a partial skeleton, including a partial skull, of an immature subadult individual. It was partially buried in the rock at the time of its description, mixed in with the fossils of another, unnamed sauropod. Classification In 202 ...

Shaximiao Formation
The Shaximiao Formation () is a Middle to Late Jurassic aged geological formation in Sichuan, China, most notable for the wealth of dinosaurs fossils that have been excavated from its strata. The Shaximiao Formation is exposed in and around the small township of Dashanpu (), situated seven kilometres north-east from Sichuan's third largest city, Zigong, in the Da'an District. Geology The Shaximiao Formation includes two distinct subunits: The upper and lower Shaximiao Formations (), although they are commonly referred to as one, simply being called the "Shaximiao Formation". The upper Shaximiao Formation is also known as the Shangshaximiao Formation, and the lower Shaximiao Formation is also known as the Xiashaximiao Formation, which are direct transliterations of the Chinese names. Both subunits primarily consist of purple-red mudstones, with variable sand inclusion. and siltstones with interbedded sandstones. Dinosaur finds The Shaximiao Formation has produced mainly ...

Middle Jurassic
The Middle Jurassic is the second epoch of the Jurassic Period. It lasted from about 174.1 to 163.5 million years ago. Fossils of land-dwelling animals, such as dinosaurs, from the Middle Jurassic are relatively rare, but geological formations containing land animal fossils include the Forest Marble Formation in England, the Kilmaluag Formation in Scotland,British Geological Survey. 2011Stratigraphic framework for the Middle Jurassic strata of Great Britain and the adjoining continental shelf: research report RR/11/06 British Geological Survey, Keyworth, Nottingham. the Daohugou Beds in China, the Itat Formation in Russia, and the Isalo III Formation of western Madagascar. Paleogeography During the Middle Jurassic Epoch, Pangaea began to separate into Laurasia and Gondwana, and the Atlantic Ocean formed. Eastern Laurasia was tectonically active as the Cimmerian plate continued to collide with Laurasia's southern coast, completely closing the Paleo-Tethys Ocean. A subd ...

Diplodocus Carnegii
''Diplodocus'' (, , or ) was a genus of diplodocid sauropod dinosaurs, whose fossils were first discovered in 1877 by S. W. Williston. The generic name, coined by Othniel Charles Marsh in 1878, is a neo-Latin term derived from Greek διπλός (''diplos'') "double" and δοκός (''dokos'') "beam", in reference to the double-beamed chevron bones located in the underside of the tail, which were then considered unique. The genus of dinosaurs lived in what is now mid-western North America, at the end of the Jurassic period. It is one of the more common dinosaur fossils found in the middle to upper Morrison Formation, between about 154 and 152 million years ago, during the late Kimmeridgian Age. The Morrison Formation records an environment and time dominated by gigantic sauropod dinosaurs, such as ''Apatosaurus'', ''Barosaurus'', ''Brachiosaurus'', ''Brontosaurus'', and ''Camarasaurus''. Its great size may have been a deterrent to the predators ''Allosaurus'' and ''Ceratos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tehuelchesaurus Benetezii
''Tehuelchesaurus'' () is a genus of dinosaur. It is named in honor of the Tehuelche people, native to the Argentinian province of Chubut, where it was first found. Description It was a moderately large (possibly long) cetiosaur-like sauropod found in the Late Jurassic (Tithonian) Cañadon Calcareo Formation at Fernandez Estancia, Chubut Province, Patagonia, Argentina; known from the holotype MPEF-PV 1125 (Museo Paleontologico Egidio Fergulio), a 50% complete skeleton, lacking a skull, but including dorsal, sacral and caudal vertebrae, parts of the forelimbs and hindlimbs, parts of the shoulder girdle and pelvis, some rib fragments, and skin impressions. ''Tehuelchesaurus'' is most similar to '' Omeisaurus'' from the Middle Jurassic of China, but is distinguished by the shape of the coracoid, the stouter radius and ulna, and the shapes of the pubis and ischium; all the dorsal vertebrae have pseudopleurocoels (deep depressions in the centra but without internal chambers ...

Galvesaurus
''Galvesaurus'', or ''Galveosaurus'', (meaning " Galve lizard") is a genus of brachiosaurid sauropod dinosaur from the Late Jurassic period. Fossils of the only known species, ''G. herreroi'', were found in Galve, Spain, hence its generic name, "Galve lizard". The specific name ''G. herreroi'' honours the discoverer, José María Herrero. Phylogeny While Royo-Torres ''et al.'' (2006) grouped ''Galvesaurus'' within Turiasauria alongside '' Losillasaurus'' and '' Turiasaurus'', Barco & Canudo (2012) noted that ''Galvesaurus'' lacks turiasaurian synapomorphies and found that it was actually a macronarian. New material described in 2019 reveals ''Galvesaurus'' to be a brachiosaurid. History During the 1980s, a fossil site known as Cuesta Lonsal, in the Kimmeridgian to Tithonian Villar del Arzobispo Formation near Galve (Teruel), Spain, was excavated by local amateur fossil hunter José María Herrero after he found the fossilized remains of a sauropod dinosaur.

Euhelopus
''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 Si ...

Europasaurus
''Europasaurus'' is a basal macronarian sauropod, a form of quadrupedal herbivorous dinosaur. It lived during the Late Jurassic (middle Kimmeridgian, about 154 million years ago) of northern Germany, and has been identified as an example of insular dwarfism resulting from the isolation of a sauropod population on an island within the Lower Saxony basin. Discovery and naming In 1998, a single sauropod tooth was discovered by private fossil collector Holger Lüdtke in an active quarry at Langenberg Mountain, between the communities of Oker, Harlingerode and Göttingerode in Germany. The Langenberg chalk quarry had been active for more than a century; rocks are quarried using blasting and are mostly processed into fertilisers. The quarry exposes a nearly continuous, thick succession of carbonate rocks belonging to the Süntel Formation, that ranges in age from the early Oxfordian to late Kimmeridgian stages and have been deposited in a shallow sea with a water depth of less ...

Bellusaurus
''Bellusaurus'' (meaning "Beautiful lizard", from Vulgar Latin ''bellus'' 'beautiful' ( masculine form) and Ancient Greek ''sauros'' 'lizard') was a small short-necked sauropod dinosaur from the Middle Jurassic which measured about long. Its fossils were found in Shishugou Formation rocks in the northeastern Junggar Basin in China. Discovery and naming The type and only known species is ''Bellusaurus sui'', formally described by Dong Zhiming in 1991. The remains of ''Bellusaurus'' were found in the Shishugou Formation in the northeastern Junggar Dzungaria (; from the Mongolian words , meaning 'left hand') is a geographical subregion in Northwest China that corresponds to the northern half of Xinjiang. It is thus also known as Beijiang, which means "Northern Xinjiang". Bounded by the A ... Basin in China. Seventeen individuals were found in a single quarry, suggesting that a herd had been killed in a flash flood. Some features suggest they may have all been juveniles. '' ...

Camarasaurus Supremus
''Camarasaurus supremus'' is a species of sauropod dinosaur that lived during the Jurassic period in what is now the western United States. It is the type species of ''Camarasaurus'', which also includes the species ''Camarasaurus grandis'', ''Camarasaurus lentus'', and ''Camarasaurus lewisi''. ''C. supremus'' was discovered by the paleontologist Edward Drinker Cope in 1877, at the outset of the Bone Wars, a period of scientific competition between Cope and his rival Othniel Marsh. ''C. supremus'' is the largest and geologically youngest species in its genus, and was contemporary with several other exceptionally large dinosaurs, such as ''Saurophaganax'' and ''Maraapunisaurus''. Despite being the first discovered species of ''Camarasaurus'', ''C. supremus'' is relatively rare and poorly known. Taxonomy ''Camarasaurus supremus'' was named by Edward Drinker Cope in 1877. It is the type species of ''Camarasaurus'', and is one of four valid species of the genus, alongside ''Camarasaur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
