Cornus Republicensis
''Cornus'' is a genus of about 30–60 species of woody plants in the family Cornaceae, commonly known as dogwoods, which can generally be distinguished by their blossoms, berries, and distinctive bark. Most are deciduous trees or shrubs, but a few species are nearly herbaceous perennial subshrubs, and some species are evergreen. Several species have small heads of inconspicuous flowers surrounded by an involucre of large, typically white petal-like bracts, while others have more open clusters of petal-bearing flowers. The various species of dogwood are native throughout much of temperate and boreal Eurasia and North America, with China, Japan, and the southeastern United States being particularly rich in native species. Species include the common dogwood ''Cornus sanguinea'' of Eurasia, the widely cultivated flowering dogwood ''( Cornus florida)'' of eastern North America, the Pacific dogwood ''Cornus nuttallii'' of western North America, the Kousa dogwood ''Cornus k ...

Maurice Mehl
Maurice Goldsmith Mehl (1887 - 1966) was an American paleontologist and professor in the Department of Geology at the University of Missouri. Life and career Mehl was born on December 25, 1887, to Frank and Rebecca Goldsmith Mehl. After graduation from Burlingame High School, he attended the University of Chicago, where he completed a B.S. in 1911 and a Ph.D. in 1914. While at Chicago, he met Lucy Jane Hull and they were married in 1912. At Chicago, Mehl studied vertebrate paleontology under the instruction of prominent paleontologist Samuel Wendell Williston. He taught at Chicago for awhile as well as at University of Wisconsin, University of Oklahoma, and Denison University before joining the University of Missouri in 1919. In addition to teaching and researching at Missouri until his retirement in 1958, where he became known simply as "Doc" Mehl, he also worked as a consultant to the Missouri Geological Survey and Water Resources. While at Missouri, he had a long and produ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1940s In Paleontology
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 '' Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

Sinopliosaurus
''Sinopliosaurus'' (meaning "Chinese more lizard"; in reference to ''Pliosaurus'') is a genus of pliosauroid plesiosaur, a type of short-necked marine reptile, alive during the Aptian and Albian stages of the Early Cretaceous (disputed ''Sinopliosaurus'' remains have been dated to the Toarcian age and were found in the Ziliujing Formation) of the People's Republic of China - its exact age is unknown. The type species, ''Sinopliosaurus weiyuanensis'', was named and described in 1944 by Yang Zhongjian.C.-C. Young. (1944). On the reptilian remains from Weiyuan, Szechuan, China. ''Bulletin of the Geological Society of China'' 24(3–4):187-205 One species, "S." ''fusuiensis'', was later shown to be based on teeth from a spinosaurid theropod dinosaur which is now known as ''Siamosaurus''. ''S. weiyuanensis'' would have lived near a coastal environment. The holotype, IVPP V140, consists of three vertebrae and a tooth, discovered in a layer of the Lianmugin Formation (Tugulu Group).Z. ...

Sauropoda
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 ...

Ornithopod
Ornithopoda () is a clade of ornithischian dinosaurs, called ornithopods (), that started out as small, bipedal running grazers and grew in size and numbers until they became one of the most successful groups of herbivores in the Cretaceous world, dominating the North American land. Their major evolutionary advantage was the progressive development of a chewing apparatus that became the most sophisticated ever developed by a non-avian dinosaur, rivaling that of modern mammals such as the domestic cow. They reached their apex of diversity and ecological dominance in the hadrosaurids (colloquially known as 'duck-bills'), before they were wiped out by the Cretaceous–Paleogene extinction event along with all other non-avian dinosaurs. Members are known from all seven continents, though they are generally rare in the Southern Hemisphere. History of research In 1870, Thomas Henry Huxley listed Iguanodontidae (coined by Cope a year earlier) as one of his three families of dinosaurs ( ...

Nomen Dubium
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Poekilopleuron
''Poekilopleuron'' (meaning "varied ribs") is a genus of tetanuran dinosaur, which lived during the middle Bathonian of the Jurassic, about 168 to 166 million years ago. The genus has been used under many different spelling variants, although only one, ''Poekilopleuron'', is valid. The type species is ''P. bucklandii'', named after William Buckland, and many junior synonyms of it have also been erected. Few material is currently known, as the holotype was destroyed in World War II, although many casts of the material still exist. Discovery and naming ''Poekilopleuron'' is a genus of theropod with a long and complex history. The holotype was discovered in July 1835 near La Maladrerie and the genus was named and first described by Jacques Amand Eudes-Deslongchamps in a report published in 1836, based on holotype material that is now destroyed. In 1837, Eudes-Deslongchamps published a more detailed account of this discovery in a monographEudes-Deslongchamps J.-A. (1837) Mémoire s ...

Edward Branson
Edward B. Branson was an American geologist and paleontologist. He was a professor of geology at the University of Missouri. Overview of career Branson earned his doctorate at the University of Chicago and joined the Geology department at the University of Missouri in 1911. During his doctoral studies, he had spent time searching for fossils near Lander, Wyoming and so he determined to set up a camp for the hands-on study of geology and paleontology nearby. Also in 1911, he came to Lander with a group of students and established the Missouri Field Geology Camp, which is now known as the Branson Field Laboratory, near Sinks Canyon State Park. The Branson Field Laboratory appears to be the oldest continually operated field geology camp in the United States. Eventually Branson formed a scientific partnership with Maurice "Doc" Mehl, another Chicago graduate who joined the Missouri faculty in 1919. Branson retired in 1948, which is when the camp was renamed in his honor. Contribu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert S
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...
