Bienosaurus
''Bienosaurus'' (meaning "Bien's lizard") is a dubious genus of thyreophoran dinosaur from the Lower Jurassic (probably Sinemurian) Lower Lufeng Formation in Yunnan Province in China. Discovery and species The Lufeng Basin in China has been a location for the collection of Early Jurassic dinosaurs since 1938. In 1938 and 1939 Chinese paleontologist Mei Nien Bien collected material from the Dark Red Beds of the lower Lufeng Formation that included the nearly complete jaw and partial skull of a relative of the armored dinosaur ''Scelidosaurus'', though it was not described as such until 2001. In 2001, Chinese paleontologist Dong Zhiming described this specimen, IVPP V 9612, as a new member of the family Scelidosauridae, ''Bienosaurus lufengensis''. The genus name is in honor of the collector Bien and combines with it the Ancient Greek word σαυρος (''sauros'') for "lizard", while the specific name is for the Lufeng Basin where the holotype skull was found. The species na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lower Lufeng Series
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.

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 di ...

Tatisaurus
''Tatisaurus'' is a genus of ornithischian dinosaur from the Early Jurassic from the Lower Lufeng Formation in Yunnan Province in China. Little is known as the remains are fragmentary. The type species is ''T. oehleri''. Discovery and species In 1948 and 1949 Father Edgar Oehler, a Catholic priest working for the Fu Jen Catholic University at Beijing, excavated fossils near the village of Da Di in Yunnan. Among them was the jaw bone of a herbivorous dinosaur. In 1965 David Jay Simmons named and described it as the type species ''Tatisaurus oehleri''. The generic name is derived from Da Di, then more usually spelled as "Ta Ti". The specific name honours Oehler. The holotype, FMNH CUP 2088, was found in the Zhangjiawa Beds of the Lufeng Formation, dating from the Sinemurian. It consists of a partial left mandible with teeth. The lower jaw bone fragment is, lacking the tip, six centimetres long. The teeth are eroded. It is the only specimen known of the species. Simmons assig ...

''Scelidosaurus'' (; with the intended meaning of "limb lizard", from Greek / meaning 'rib of beef' and ''sauros''/ meaning 'lizard')Liddell & Scott (1980). Greek-English Lexicon, Abridged Edition. Oxford University Press, Oxford, UK. is a genus of herbivorous armoured ornithischian dinosaur from the Jurassic of England. ''Scelidosaurus'' lived during the Early Jurassic Period, during the Sinemurian to Pliensbachian stages around 191 million years ago, at the time when Europe formed an island archipelago. Its fossils have been found in the Charmouth Mudstone Formation near Charmouth in Dorset, England, and these fossils are known for their excellent preservation.

Thyreophoran
Thyreophora ("shield bearers", often known simply as "armored dinosaurs") is a group of armored ornithischian dinosaurs that lived from the Early Jurassic until the end of the Cretaceous. Thyreophorans are characterized by the presence of body armor lined up in longitudinal rows along the body. Primitive forms had simple, low, keeled scutes or osteoderms, whereas more derived forms developed more elaborate structures including spikes and plates. Most thyreophorans were herbivorous and had relatively small brains for their body size. Thyreophora includes two major subgroups, Ankylosauria and Stegosauria. In both clades, the forelimbs were much shorter than the hindlimbs, particularly in stegosaurs. Thyreophora has been defined as the group consisting of all species more closely related to '' Ankylosaurus'' and '' Stegosaurus'' than to ''Iguanodon'' and ''Triceratops''. It is the sister group of Cerapoda within Genasauria. Characteristics Members of Thyreophora are charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sinornithoides
''Sinornithoides'' (meaning "Chinese bird form") is a genus of troodontid theropod dinosaurs containing the single species ''Sinornithoides youngi''. ''S. youngi'' lived during the Early Cretaceous (Aptian/Albian stage, around 113 million years ago).Sereno, P.C. (2010). "Taxonomy, cranial morphology, and relationships of parrot-beaked dinosaurs (Ceratopsia: ''Psittacosaurus'')." ''New Perspectives on Horned Dinosaurs''. Bloomington: Indiana, 21-58. It measured approximately one meter long (3.3 ft). It lived in Inner Mongolia, China, and probably ate invertebrates and other small prey. They lived in what is now Mongolia, which was part of Laurasia. Discovery In 1988, a Chinese-Canadian expedition discovered the remains of a small theropod near Huamuxiao, in the Ordos Basin of Inner Mongolia. ''Sinornithoides youngi'', the type species, was named and described in 1993/1994 by Dale Russell and Dong Zhiming based on this fossil specimen from the Lower Cretaceous Ejinhoro Fo ...

Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...
