Han (trilobite)
''Han'' is a monotypic genus of agnostid trilobite, whose sole member is ''Han solo''. The type specimen of ''H. solo'' was found in marine strata of the Arenig to Llanvirn-aged Zitai Formation of Middle Ordovician southern China, and is named after the character in ''Star Wars''. Taxonomy This taxon was erected in 2005, based upon fossil material found in beds of lower Zitai Formation exposed in Maocaopu, Reshi, Taoyuan County in north Hunan, China. Fossil material include a cephalon and two pygidia. It was found to belong to family Diplagnostidae, subfamily Pseudagnostinae; it was originally thought to be most closely related to the genus '' Pseudorhaptagnostus'', but it differed substantially from that genus in both some important diagnostic characters, and in the age of the beds in it was deposited, so a new genus was erected. Etymology According to the original publication, the generic name ''Han'' is a reference to the Han Chinese, the largest ethnic group in China; ...

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...

Fossil Taxa Described In 2005
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...

Agnostida Genera
Agnostida is an order of arthropod which have classically been seen as a group of highly modified trilobites, though some recent research has doubted this placement. Regardless, they appear to be close relatives as part of the Artiopoda. They are present in the Lower Cambrian fossil record along with trilobites from the Redlichiida, Corynexochida, and Ptychopariida orders, and were highly diverse throughout the Cambrian. Agnostidan diversity severely declined during the Cambrian-Ordovician transition, and the last agnostidans went extinct in the Late Ordovician. Systematics The Agnostida are divided into two suborders — Agnostina and Eodiscina — which are then subdivided into a number of families. As a group, agnostids are isopygous, meaning their pygidium is similar in size and shape to their cephalon. Most agnostid species were eyeless. The systematic position of the order Agnostida within the class Trilobita remains uncertain, and there has been continuing ...

The Muppet Show
''The Muppet Show'' is a sketch comedy television series created by Jim Henson and featuring the Muppets. The series originated as two pilot episodes produced by Henson for ABC in 1974 and 1975. While neither episode was moved forward as a series and other networks in the United States rejected Henson's proposals, British producer Lew Grade expressed enthusiasm for the project and agreed to co-produce ''The Muppet Show'' for the British channel ATV. Five seasons, totalling 120 episodes, were broadcast on ATV and other ITV franchises in the United Kingdom and in later first-run syndication in the US from 1976 to 1981. The programme was produced and recorded at ATV Elstree Studios, England. ''The Muppet Show'' is presented as a variety show, featuring recurring sketches and musical numbers interspersed with plotlines taking place backstage and in other areas of the venue. Within its context, Kermit the Frog (performed by Henson) acts as showrunner and host, who tries to mainta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waldorf And Statler
Statler and Waldorf are a pair of Muppet characters best known for their cantankerous opinions and shared penchant for heckling. The two elderly men first appeared in ''The Muppet Show'' in 1975, where they consistently jeered the entirety of the cast and their performances from their balcony seats. Created by Jim Henson, the characters have been performed by numerous puppeteers, including Henson, in a variety of films and television productions within the Muppet franchise. Statler and Waldorf are named after two landmark New York City hotels, the Statler Hilton and the Waldorf-Astoria. Characters The characters are known for their heckling. In ''The Muppet Show'', the two are always criticizing Fozzie Bear's humor, except for one occasion where Fozzie heckles them back. In contrast, they find ''themselves'' vastly entertaining and inevitably burst into mutual laughter at their own witticisms. It is later revealed in the '' A Muppet Family Christmas'' special that the two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geragnostus Waldorfstatleri
''Geragnostus'' is a genus of very small agnostid trilobites whose fossils are found Ordovician-aged marine strata from Eurasia, North America and Argentina. Etymology * ''balanolobus'' is derived from the Greek 'balanos', acorn, and 'lobos', lobe, in reference to the outline of the rear lobe of the rhachis. * ''sidenbladhi'' has been named in honor of the Swedish philosopher and paleontologist Elis Sidenbladh. * ''waldorfstatleri'' is named after the Muppets Statler and Waldorf for the likeness of the rhachis to their heads. Taxonomy ''Geragnostus'' is very similar to '' Trinodus'' and may in future be included in that genus. In ''Trinodus'' the posterior lobe (M3) of the pygidial axis (or rhachis) is clearly shorter than the anterior and middle lobes (M1+M2) combined, while in ''Geragnostus'' it is equal or greater in length. ''Geragnostus'' is not closely related to ''Micragnostus'', because its glabella is structurally different. Species previously assigned to ''Gera ...

Ethnic Group
An ethnic group or an ethnicity is a grouping of people who identify with each other on the basis of shared attributes that distinguish them from other groups. Those attributes can include common sets of traditions, ancestry, language, history, society, culture, nation, religion, or social treatment within their residing area. The term ethnicity is often times used interchangeably with the term nation, particularly in cases of ethnic nationalism, and is separate from the related concept of races. Ethnicity may be construed as an inherited or as a societally imposed construct. Ethnic membership tends to be defined by a shared cultural heritage, ancestry, origin myth, history, homeland, language, or dialect, symbolic systems such as religion, mythology and ritual, cuisine, dressing style, art, or physical appearance. Ethnic groups may share a narrow or broad spectrum of genetic ancestry, depending on group identification, with many groups having mixed genetic ancestry. Ethnic ...
