Neotype Male Of Electrostephanus Petiolatus Brues In Baltic Amber (AMNH B-JWJ-260)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Alectrosaurus
''Alectrosaurus'' (; meaning "alone lizard") is a genus of tyrannosauroid theropod dinosaur that lived in Asia during the Late Cretaceous period, about some 96 million years ago in what is now the Iren Dabasu Formation. It was a medium-sized, moderately-built, ground-dwelling, bipedal carnivore, estimated at with a body shape similar to its much larger advanced relative, ''Tyrannosaurus''. ''Alectrosaurus'' was a very fast running tyrannosauroid as indicated by the elongated hindlimbs that likely filled the niche of a pursuit predator, a trait that seems to be lost by the advanced and robust tyrannosaurids, in adulthood. Discovery and naming In 1923, the Third Asiatic Expedition of the American Museum of Natural History, led by chief paleontologist Walter W. Granger, was hunting for dinosaur fossils in Mongolia. On April 25 in the gobi desert, assistant paleontologist George Olsen excavated and recovered the holotype AMNH 6554, a nearly complete right hindlimb. This included a ...

Two Medicine Formation
The Two Medicine Formation is a geological formation, or rock body, in northwestern Montana and southern Alberta that was deposited between and (million years ago), during Campanian (Late Cretaceous) time. It crops out to the east of the Rocky Mountain Overthrust Belt, and the western portion (about thick) of this formation is folded and faulted while the eastern part, which thins out into the Sweetgrass Arch, is mostly undeformed plains. Below the formation are the nearshore (beach and tidal zone) deposits of the Virgelle Sandstone, and above it is the marine Bearpaw Shale. Throughout the Campanian, the Two Medicine Formation was deposited between the western shoreline of the Late Cretaceous Interior Seaway and the eastward advancing margin of the Cordilleran Overthrust Belt. The Two Medicine Formation is mostly sandstone, deposited by rivers and deltas.

Cavusgnathus
''Cavusgnathus'' is an extinct genus of conodonts. Glen K.

Whittow defines it as a "Scottish term for a deep valley in the Highlands" that is "narrower ... stated in 1963 that "conodont workers have considered '' Idiognathoides'' to be a junior synonym of '' Polygnathodella'' but it now proves to be a junior synonym of ''Cavusgnathus''.

Oklahoma (; Choctaw language, Choctaw: ; chr, ᎣᎧᎳᎰᎹ, ''Okalahoma'' ) is a U.S. state, state in the South Central United States, South Central region of the United States, bordered by Texas on the south and west, Kansas on the north, Missouri on the northeast, Arkansas on the east, New Mexico on the west, and Colorado on the northwest. Partially in the western extreme of the Upland South, it is the List of U.S. states and territories by area, 20th-most extensive and the List of U.S. states and territories by population, 28th-most populous of the 50 United States. Its residents are known as Oklahomans and its capital and largest city is Oklahoma City. The state's name is derived from the Choctaw language, Choctaw words , 'people' and , which translates as 'red'. Oklahoma is also known informally by its List of U.S. state and territory nicknames, nickname, "Sooners, The Sooner State", in reference to the settlers who staked their claims on land before the official op ...

Pennsylvanian (geology)
The Pennsylvanian ( , also known as Upper Carboniferous or Late Carboniferous) is, in the International Commission on Stratigraphy, ICS geologic timescale, the younger of two period (geology), subperiods (or upper of two system (stratigraphy), subsystems) of the Carboniferous Period. It lasted from roughly . As with most other geochronology, geochronologic units, the stratum, rock beds that define the Pennsylvanian are well identified, but the exact date of the start and end are uncertain by a few hundred thousand years. The Pennsylvanian is named after the U.S. state of Pennsylvania, where the coal-productive beds of this age are widespread. The division between Pennsylvanian and Mississippian (geology), Mississippian comes from North American stratigraphy. In North America, where the early Carboniferous beds are primarily marine limestones, the Pennsylvanian was in the past treated as a full-fledged geologic period between the Mississippian and the Permian. In parts of Europe, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RV Hollingsworth
A recreational vehicle, often abbreviated as RV, is a motor vehicle or trailer that includes living quarters designed for accommodation. Types of RVs include motorhomes, campervans, coaches, caravans (also known as travel trailers and camper trailers), fifth-wheel trailers, popup campers, and truck campers. Features Typical amenities of an RV include a kitchen, a bathroom, and one or more sleeping facilities. RVs can range from utilitarian – containing only sleeping quarters and basic cooking facilities – to luxurious, with features like air conditioning (AC), water heaters, televisions and satellite receivers, and quartz countertops, for example. RVs can either be trailers (which are towed behind motor vehicles) or self-propelled vehicles. Most RVs are single-deck; however, double-deck RVs also exist. To allow a more compact size while in transit, larger RVs often have expandable sides (called slide-outs) or canopies that are deployed when stationary. History T ...

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] |
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.
