David Leigh Clark
David L. Clark is a paleontologist. He was the W.H. Twenhofel Professor of Geology and Geophysics at the University of Wisconsin–Madison, Madison, Wisconsin. In 1972, he described the conodont genus ''Neostreptognathodus''. Awards and tributes In 2001, he received the Raymond C. Moore Medal which is awarded by the Society for Sedimentary Geology to persons who have made significant contributions in the field which have promoted the science of stratigraphy by research in paleontology. The conodont genus name ''Clarkina ''Clarkina'' is an extinct genus of conodonts. It is considered to be an offshore, outer shelf or basinal, deep-water taxon.

University Of Wisconsin–Madison
The University of Wisconsin–Madison (University of Wisconsin, Wisconsin, UW, UW–Madison, or simply Madison) is a public land-grant research university in Madison, Wisconsin. Founded when Wisconsin achieved statehood in 1848, UW–Madison is the official state university of Wisconsin and the flagship campus of the University of Wisconsin System. It was the first public university established in Wisconsin and remains the oldest and largest public university in the state. It became a land-grant institution in 1866. The main campus, located on the shores of Lake Mendota, includes four National Historic Landmarks. The university also owns and operates the University of Wisconsin–Madison Arboretum, located south of the main campus, which is also a National Historic Landmark. UW–Madison is organized into 20 schools and colleges, which enrolled 33,506 undergraduate, 9,772 graduate, 1,968 special, and 2,686 professional students in 2021. Its academic programs include 136 u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madison, Wisconsin
Madison is the county seat of Dane County and the capital city of the U.S. state of Wisconsin. As of the 2020 census the population was 269,840, making it the second-largest city in Wisconsin by population, after Milwaukee, and the 80th-largest in the U.S. The city forms the core of the Madison Metropolitan Area which includes Dane County and neighboring Iowa, Green, and Columbia counties for a population of 680,796. Madison is named for American Founding Father and President James Madison. The city is located on the traditional land of the Ho-Chunk, and the Madison area is known as ''Dejope'', meaning "four lakes", or ''Taychopera'', meaning "land of the four lakes", in the Ho-Chunk language.

Raymond C
Raymond is a male given name. It was borrowed into English from French (older French spellings were Reimund and Raimund, whereas the modern English and French spellings are identical). It originated as the Germanic ᚱᚨᚷᛁᚾᛗᚢᚾᛞ (''Raginmund'') or ᚱᛖᚷᛁᚾᛗᚢᚾᛞ (''Reginmund''). ''Ragin'' (Gothic) and ''regin'' (Old German) meant "counsel". The Old High German ''mund'' originally meant "hand", but came to mean "protection". This etymology suggests that the name originated in the Early Middle Ages, possibly from Latin. Alternatively, the name can also be derived from Germanic Hraidmund, the first element being ''Hraid'', possibly meaning "fame" (compare ''Hrod'', found in names such as Robert, Roderick, Rudolph, Roland, Rodney and Roger) and ''mund'' meaning "protector". Despite the German and French origins of the English name, some of its early uses in English documents appear in Latinized form. As a surname, its first recorded appearance in Br ...

''Clarkina'' is an extinct genus of conodonts. It is considered to be an offshore, outer shelf or basinal, deep-water taxon. The genus name is a tribute to David Leigh Clark. Synonyms ''Clarkina'' Soodan 1975 is a junior synonym for the prehistoric sea cucumber '' Soodanella'' Huddleston 1982 in the family Priscopedatidae. ''Clarkina'' Jordan & Evermann, 1927 is a junior synonym for the cyprinid fish genus ''Mylocheilus'' Agassiz, 1855. Use in stratigraphy The top of the Capitanian (or the base of the Wuchiapingian) is defined as the place in the stratigraphic record where the conodont subspecies ''Clarkina postbitteri postbitteri'' first appears.

Streptognathodus Clarki
''Streptognathodus'' is an extinct genus of conodonts from the Late Carboniferous to Early Permian. Use in stratigraphy Late Carboniferous The top of the Kasimovian stage is close to the first appearance of ''Streptognathodus zethus''. The golden spike for the Kasimovian stage has not yet been assigned (in 2008). The Kasimovian is subdivided into three conodont biozones: *''Idiognathodus toretzianus'' Zone *''Idiognathodus sagittatus'' Zone *''Streptognathodus excelsus'' and ''Streptognathodus makhlinae'' Zone The base of the Gzhelian is at the first appearance of ''Streptognathodus zethus''. The top of the stage (also the top base of the Silesian and the base of the Permian system) is at the first appearance of ''Streptognathodus isolatus'' within the ''Streptognathus "wabaunsensis"'' chronocline. The Gzhelian stage is subdivided into five biozones, based on the conodont genus ''Streptognathodus'': * ''Streptognathodus wabaunsensis'' and ''Streptognathodus bellus'' Zone ...

Conodont
Conodonts (Greek ''kōnos'', "cone", + ''odont'', "tooth") are an extinct group of agnathan (jawless) vertebrates resembling eels, classified in the class Conodonta. For many years, they were known only from their tooth-like oral elements, which are usually found in isolation and are now called conodont elements. Knowledge about soft tissues remains limited. They existed in the world's oceans for over 300 million years, from the Cambrian to the beginning of the Jurassic. Conodont elements are widely used as index fossils, fossils used to define and identify geological periods. The animals are also called Conodontophora (conodont bearers) to avoid ambiguity. Discovery and understanding of conodonts The teeth-like fossils of the conodont were first discovered by Heinz Christian Pander and the results published in Saint Petersburg, Russia, in 1856. The name ''pander'' is commonly used in scientific names of conodonts. It was only in the early 1980s that the first fossil evidence of ...

Great Basin
The Great Basin is the largest area of contiguous endorheic basin, endorheic watersheds, those with no outlets, in North America. It spans nearly all of Nevada, much of Utah, and portions of California, Idaho, Oregon, Wyoming, and Baja California. It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin in Death Valley to the highest point of the contiguous United States, less than away at the summit of Mount Whitney. The region spans several physical geography, physiographic divisions, biomes, ecoregions, and deserts. Definition The term "Great Basin" is applied to hydrography, hydrographic, ecology, biological, floristic province, floristic, physiographic, topography, topographic, and Ethnography, ethnographic geographic areas. The name was originally coined by John C. Frémont, who, based on information gleaned from Joseph R. Walker as well as his own travels, recognized the hydrographic nature o ...

University Of Wisconsin–Madison Faculty
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...
