Grès Supérieurs Formation
The Grès supérieurs Formation (French for "Upper sandstone") is a geological formation in Laos whose strata date back to the Aptian to Albian stages of the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel et al., pp.563-570 It is equivalent to the Khok Kruat Formation of Thailand.

Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...

David B
David Robert Jones (8 January 194710 January 2016), known professionally as David Bowie ( ), was an English singer-songwriter and actor. A leading figure in the music industry, he is regarded as one of the most influential musicians of the 20th century. Bowie was acclaimed by critics and musicians, particularly for his innovative work during the 1970s. His career was marked by reinvention and visual presentation, and his music and stagecraft had a significant impact on popular music. Bowie developed an interest in music from an early age. He studied art, music and design before embarking on a professional career as a musician in 1963. "Space Oddity", released in 1969, was his first top-five entry on the UK Singles Chart. After a period of experimentation, he re-emerged in 1972 during the glam rock era with his flamboyant and androgynous alter ego Ziggy Stardust (character), Ziggy Stardust. The character was spearheaded by the success of Bowie's single "Starman (song), Starma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ichthyovenator Laosensis Life Reconstruction By PaleoGeek
''Ichthyovenator'' is a genus of spinosaurid dinosaur that lived in what is now Laos, sometime between 125 and 113 million years ago, during the Aptian stage of the Early Cretaceous period. It is known from fossils collected from the Grès supérieurs Formation of the Savannakhet Basin, the first of which were found in 2010, consisting of a partial skeleton without the skull or limbs. This specimen became the holotype of the new genus and species ''Ichthyovenator laosensis'', and was described by palaeontologist Ronan Allain and colleagues in 2012. The generic name, meaning "fish hunter", refers to its assumed piscivorous lifestyle, while the specific name alludes to the country of Laos. In 2014, it was announced that more remains from the dig site had been recovered; these fossils included teeth, more vertebrae (backbones) and a pubic bone from the same individual. The holotype specimen is estimated to have been between long and to have weighed . ''Ichthyovenator''s tee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spinosaurid
The Spinosauridae (or spinosaurids) are a clade or family of tetanuran theropod dinosaurs comprising ten to seventeen known genera. They came into prominence during the Cretaceous period. Spinosaurid fossils have been recovered worldwide, including Africa, Europe, South America and Asia. Their remains have generally been attributed to the Early to Mid Cretaceous. Spinosaurids were large bipedal carnivores. Their crocodilian-like skulls were long, low and narrow, bearing conical teeth with reduced or absent serrations. The tips of their upper and lower jaws fanned out into a spoon-shaped structure similar to a rosette, behind which there was a notch in the upper jaw that the expanded tip of the lower jaw fit into. The nostrils of spinosaurids were retracted to a position further back on the head than in most other theropods, and they had bony crests on their heads along the midline of their skulls. Their robust shoulders wielded stocky forelimbs, with three-fingered hands that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Titanosaurus
''Titanosaurus'' (; ) is a dubious genus of sauropod dinosaurs, first described by Richard Lydekker in 1877.R. Lydekker. (1877). Notices of new and other Vertebrata from Indian Tertiary and Secondary rocks. ''Records of the Geological Survey of India'' 10(1):30-43 It is known from the Maastrichtian (Upper Cretaceous) Lameta Formation of India. Discovery and naming ''Titanosaurus'', literally meaning 'titanic lizard', was named after the mythological Titans. ''Titanosaurus'' was the first Indian dinosaur to be named and properly described, having been recorded for the first time in 1877. The type species, ''T. indicus'', was named in 1877, and the second species, ''T. blanfordi'', was named in 1879.R. Lydekker. (1879). Fossil Reptilia and Batrachia. ''Memoirs of the Geological Survey of India. Palaeontologia Indica, Series IV. Indian Pretertiary Vertebrata'' 1(3):1-36 Both species were named by Richard Lydekker.

Sauropod
Sauropoda (), whose members are known as sauropods (; from '' sauro-'' + '' -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 genera include ''Brachiosaurus'', ''Diplodocus'', ''Apatosaurus'' and ''Brontosaurus''. 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 occurrence of the group in the Late Triassic. By the Late Jurassic (150 million yea ...

Tangvayosaurus
''Tangvayosaurus'' (meaning "Tang Vay lizard") is a genus of sauropod dinosaur from the Aptian-Albian age Lower Cretaceous Gres superieurs Formation of Savannakhet Province, Laos. It was a basal somphospondylan, about 15 m long, and is known from the remains of two or three individuals. Description It is based on TV4-1 to TV4-36, consisting of a partial pelvis, several back vertebrae and a tail vertebra, ribs, and an upper arm bone ( humerus). Another skeleton includes 38 tail vertebrae, a neck vertebra, and most of a hind limb. The type species, ''Tangvayosaurus hoffeti'', was described by a group of a dozen scientists led by Ronan Allain in 1999 and the species name honours French palaeontologist Joshua Hoffet (1901-disappeared 1945). Allain ''et al.'' also referred the old species ''"Titanosaurus" falloti'' (Hoffet, 1942),J.-H. Hoffet. (1942).

Iguanodontia
Iguanodontia (the iguanodonts) is a clade of herbivorous dinosaurs that lived from the Middle Jurassic to Late Cretaceous. Some members include ''Camptosaurus'', ''Dryosaurus'', ''Iguanodon'', ''Tenontosaurus'', and the hadrosaurids or "duck-billed dinosaurs". Iguanodontians were one of the first groups of dinosaurs to be found. They are among the best known of the dinosaurs, and were among the most diverse and widespread herbivorous dinosaur groups of the Cretaceous period. Classification Iguanodontia is often listed as an infraorder within a suborder Ornithopoda, though Benton (2004) lists Ornithopoda as an infraorder and does not rank Iguanodontia. Traditionally, iguanodontians were grouped into the superfamily Iguanodontoidea and family Iguanodontidae. However, phylogenetic studies show that the traditional "iguanodontids" are a paraphyletic grade leading up to the hadrosaurs (duck-billed dinosaurs). Groups like Iguanodontoidea are sometimes still used as unranked clades ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
