Rhoetosaurus Brownei
''Rhoetosaurus'' (meaning "Rhoetos lizard"), named after Rhoetus, a titan in Greek mythology, is a genus of sauropod dinosaur from the Jurassic ( Oxfordian) Walloon Coal Measures of what is now eastern Australia. ''Rhoetosaurus'' is estimated to have been about long, weighing about .Paul, G.S., 2010, ''The Princeton Field Guide to Dinosaurs'', Princeton University Press p. 173 Subsequent authors have sometimes misspelled the name: ''Rhaetosaurus'' (de Lapparent & Laverat, 1955); ''Rheteosaurus'' (Yadagiri, Prasad & Satsangi, 1979). Discovery and species In 1924, Heber Longman, self-trained paleontologist at (and later director of) the Queensland Museum in Brisbane, learned of a large fossil reptile skeleton exposed in the Walloon Coal Measures at Durham Downs near Roma in southern inland Queensland. The station manager, Arthur Browne, forwarded fragments of bone to Longman, and was honoured with the dinosaur's specific name ''brownei''. The initial collection was of 22 tail ...

Oxfordian (stage)
The Oxfordian is, in the International Commission on Stratigraphy, ICS' geologic timescale, the earliest age (geology), age of the Late Jurassic epoch (geology), Epoch, or the lowest stage (stratigraphy), stage of the Upper Jurassic series (stratigraphy), Series. It spans the time between 161.5 ± 1.0 Annum#SI prefix multipliers, Ma and 154.8 ± 0.8 Ma (million years ago). The Oxfordian is preceded by the Callovian and is followed by the Kimmeridgian. Stratigraphic definitions The Oxfordian Stage was called "Clunch Clay and Shale" by William Smith (1815–1816); in 1818 W. Buckland described them under the unwieldy title "Oxford, Forest or Fen Clay". The term Oxfordian was introduced by Alcide d'Orbigny in 1844. The name is derived from the English city of Oxford, where the beds are well developed, but they crop out almost continuously from Dorset to the coast of Yorkshire, generally forming low, broad valleys. They are well exposed at Weymouth, Dorset, Weymouth, Oxford, Bedfor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queensland
Queensland ( , commonly abbreviated as Qld) is a States and territories of Australia, state in northeastern Australia, and is the second-largest and third-most populous state in Australia. It is bordered by the Northern Territory, South Australia and New South Wales to the west, south-west and south, respectively. To the east, Queensland is bordered by the Coral Sea and the Pacific Ocean; to the state's north is the Torres Strait, separating the Australian mainland from Papua New Guinea, and the Gulf of Carpentaria to the north-west. With an area of , Queensland is the world's List of country subdivisions by area, sixth-largest subnational entity; it List of countries and dependencies by area, is larger than all but 16 countries.

Taxa Named By Albert Heber Longman
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dinosaur Genera
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic Geological period, period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the #Evolutionary history, evolution of dinosaurs is a subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya and their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, Evolution of birds, having evolved from earlier Theropoda, theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Dinosaurs are varied from taxonomy (biology), taxonomic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sauropoda
Sauropoda (), whose members are known as sauropods (; from ''wikt:sauro-, sauro-'' + ''wikt:-pod, -pod'', 'lizard-footed'), is a clade of saurischian ('lizard-hipped') dinosaurs. Sauropods had very long necks, long tails, small heads (relative to the rest of their body), and four thick, pillar-like legs. They are notable for the enormous sizes attained by some species, and the group includes the largest animals to have ever lived on land. Well-known genus, genera include ''Apatosaurus'', ''Argentinosaurus'', ''Alamosaurus'', ''Brachiosaurus'', ''Camarasaurus'', ''Diplodocus,'' and ''Mamenchisaurus''. The oldest known unequivocal sauropod dinosaurs are known from the Early Jurassic. ''Isanosaurus'' and ''Antetonitrus'' were originally described as Triassic sauropods, but their age, and in the case of ''Antetonitrus'' also its sauropod status, were subsequently questioned. Sauropod-like sauropodomorph tracks from the Fleming Fjord Formation (Greenland) might, however, indicate the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neosauropoda
Neosauropoda is a clade within Dinosauria, coined in 1986 by Argentina, Argentine paleontologist José Bonaparte and currently described as ''Saltasaurus loricatus'', ''Diplodocus longus'', and all animals directly descended from their most recent common ancestor. The group is composed of two subgroups: Diplodocoidea and Macronaria. Arising in the early Jurassic and persisting until the Cretaceous-Paleogene extinction event, Cretaceous–Paleogene extinction event, Neosauropoda contains the majority of sauropod genera, including genera such as ''Apatosaurus'', ''Brachiosaurus'', and ''Diplodocus''. It also includes giants such as ''Argentinosaurus'', ''Patagotitan'' and ''Sauroposeidon'', and its members remain the largest land animals ever to have lived. When Bonaparte first coined the term Neosauropoda in 1986, he described the clade as comprising “end-Jurassic” sauropods. While Neosauropoda does appear to have originated at the end of the Jurassic period, it also includes m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eusauropoda
Eusauropoda (meaning "True Lizard Foot") is a derived clade of sauropod dinosaurs. Eusauropods represent the node-based group that includes all descendant sauropods starting with the basal eusauropods of '' Shunosaurus'', and possibly '' Barapasaurus'', and '' Amygdalodon'', but excluding ''Vulcanodon'' and '' Rhoetosaurus''. The Eusauropoda was coined in 1995 by Paul Upchurch to create a monophyletic new taxonomic group that would include all sauropods, except for the vulcanodontids. Eusauropoda are herbivorous, quadrupedal, and have long necks. They have been found in South America, Europe, North America, Asia, Australia, and Africa. The temporal range of Eusauropoda ranges from the early Jurassic to the Latest Cretaceous periods. The most basal forms of eusauropods are not well known and because the cranial material for the ''Vulcanodon'' is not available, and the distribution of some of these shared derived traits that distinguish Eusauropoda is still completely clear.

Shunosaurus
''Shunosaurus'', meaning "Lizard from Sichuan", is a genus of sauropod dinosaur from Late Jurassic ( Oxfordian) beds in Sichuan Province in China, from 161 to 157 Million years ago. The name derives from "Shu", an ancient name for the Sichuan province. Discovery and species The first fossil of ''Shunosaurus'' was discovered in 1977 by a group of students, practising paleontological excavation at a road bank. The type species, ''Shunosaurus lii'', was described and named by Dong Zhiming, Zhou Shiwu and Zhang Yihong in 1983. The generic name derives from "Shu", an ancient name for Sichuan. The specific name honours hydrologist Li Bing, the governor of Sichuan in the third century BC. The holotype, IVPP V.9065, was collected from the Lower Xiashaximiao Formation near Dashanpu, Zigong. It consists of a partial skeleton. Later about twenty more major specimens were discovered, including several complete or near-complete skeletons, skulls and juveniles, making ''Shunosaurus'' ...

Cetiosauridae
Cetiosauridae is a family of sauropod dinosaurs which was first proposed by Richard Lydekker in 1888. While traditionally a wastebasket taxon containing various unrelated species, some recent studies have found that it may represent a natural clade. Alongside ''Cetiosaurus ''Cetiosaurus'' ( meaning 'whale lizard', from the Greek '/ meaning 'sea monster' (later, 'whale') and '/ meaning 'lizard'), is a genus of herbivorous sauropod dinosaur from the Middle Jurassic Period, living about 171 to 165 million years ago ...'' from the Middle Jurassic of Britain, other taxa recently assigned to the family include '' Lapparentosaurus'' from the Middle Jurassic of Madagascar, and '' Patagosaurus'' from the late Early-Middle Jurassic of Patagonia, which share autapomorphies with ''Cetiosaurus'' that are not shared by other eusauropods. Additionally, at least one study has suggested that the mamenchisaurids may represent a sub-group of the cetiosaurids, which would be termed Mamenchis ...

Friedrich Von Huene
Baron Friedrich Richard von Hoyningen-Huene (22 March 1875 – 4 April 1969) was a German nobleman paleontologist who described a large number of dinosaurs, more than anyone else in 20th-century Europe. He studied a range of Permo-Carboniferous tetrapods. He worked at the collections of the institute and museum for geology and paleontology at the University of Tübingen. Biography Von Huene was born in Tübingen, Kingdom of Württemberg and came from a noble Baltic German family. He took this Baltic identity to heart and would later call his home on Zeppelinstraße (now Payerstraße) as ''Villa Baltica''. His father Johannes von Hoyningen called Huene was a Lutheran minister who had studied theology at Göttingen, Tübingen and Dorpat. His mother Alexandra Baronesse Stackelberg came from an Estonian noble family. The junior Huene was also brought up with deeply religious beliefs. He grew up in Switzerland as his father taught at Basel. He also visited Latvia as a child and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gondwana
Gondwana ( ; ) was a large landmass, sometimes referred to as a supercontinent. The remnants of Gondwana make up around two-thirds of today's continental area, including South America, Africa, Antarctica, Australia (continent), Australia, Zealandia, Arabian Peninsula, Arabia, and the Indian subcontinent. Gondwana was formed by the Accretion (geology), accretion of several cratons (large stable blocks of the Earth's crust), beginning with the East African Orogeny, the collision of India and Geography of Madagascar, Madagascar with East Africa, and culminating in with the overlapping Brasiliano orogeny, Brasiliano and Kuunga orogeny, Kuunga orogenies, the collision of South America with Africa, and the addition of Australia and Antarctica, respectively. Eventually, Gondwana became the largest piece of continental crust of the Paleozoic Era, covering an area of some , about one-fifth of the Earth's surface. It fused with Laurasia during the Carboniferous to form Pan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
