Camposipterus Nasutus
''Camposipterus'' is a genus of pterodactyloid pterosaur from the Early Cretaceous of England. Fossil remains of ''Camposipterus'' dated back to the Early Cretaceous, about 112 million years ago. Discovery and naming In 1869, Harry Govier Seeley, based on a fossil found at Haslingfield, Cambridgeshire, named ''Ptenodactylus nasutus'',Seeley, H.G., 1869, ''Index to the fossil remains of Aves, Ornithosauria, and Reptilia, from the Secondary System of Strata arranged in the Woodwardian Museum of the University of Cambridge''. Deighton, Bell and Co., Cambridge, xxiii + 143 pp at the same time disclaiming the name which makes it invalid by modern standards. In 1870, Seeley had realized that the generic name ''Ptenodactylus'' had been preoccupied, so he renamed the species into '' Ornithocheirus nasutus''.Seeley, H.G., 1870, ''The Ornithosauria: an elementary study of the bones of pterodactyls, made from fossil remains found in the Cambridge Upper Greensand, and arranged in the ...

Early Cretaceous
The Early Cretaceous ( geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java-Manihiki-Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kerguelen P ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Adam Sedgwick
Adam Sedgwick (; 22 March 1785 – 27 January 1873) was a British geologist and Anglican priest, one of the founders of modern geology. He proposed the Cambrian and Devonian period of the geological timescale. Based on work which he did on Welsh rock strata, he proposed the Cambrian period in 1835, in a joint publication in which Roderick Murchison also proposed the Silurian period. Later in 1840, to resolve what later became known as the Great Devonian Controversy about rocks near the boundary between the Silurian and Carboniferous periods, he and Murchison proposed the Devonian period. Though he had guided the young Charles Darwin in his early study of geology and continued to be on friendly terms, Sedgwick was an opponent of Darwin's theory of evolution by means of natural selection. He strongly opposed the admission of women to the University of Cambridge, in one conversation describing aspiring female students as "nasty forward minxes." Life and career Sedgwick was b ...

Albian
The Albian is both an age of the geologic timescale and a stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early/Lower Cretaceous Epoch/Series. Its approximate time range is 113.0 ± 1.0 Ma to 100.5 ± 0.9 Ma (million years ago). The Albian is preceded by the Aptian and followed by the Cenomanian. Stratigraphic definitions The Albian Stage was first proposed in 1842 by Alcide d'Orbigny. It was named after Alba, the Latin name for River Aube in France. A Global Boundary Stratotype Section and Point (GSSP), ratified by the IUGS in 2016, defines the base of the Albian as the first occurrence of the planktonic foraminiferan '' Microhedbergella renilaevis'' at the Col de Pré-Guittard section, Arnayon, Drôme, France. The top of the Albian Stage (the base of the Cenomanian Stage and Upper Cretaceous Series) is defined as the place where the foram species '' Rotalipora globotruncanoides'' first appears in the stratigraphic column.

Cenomanian
The Cenomanian is, in the ICS' geological timescale, the oldest or earliest age of the Late Cretaceous Epoch or the lowest stage of the Upper Cretaceous Series. An age is a unit of geochronology; it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding age. Both age and stage bear the same name. As a unit of geologic time measure, the Cenomanian Age spans the time between 100.5 and 93.9 million years ago (Mya). In the geologic timescale, it is preceded by the Albian and is followed by the Turonian. The Upper Cenomanian starts around at 95 Mya. The Cenomanian is coeval with the Woodbinian of the regional timescale of the Gulf of Mexico and the early part of the Eaglefordian of the regional timescale of the East Coast of the United States. At the end of the Cenomanian, an anoxic event took place, called the Cenomanian-Turonian boundary event or the "Bonarelli event", that is associated with a minor extinction event for marine spec ...

Cambridge Greensand
The Cambridge Greensand is a geological unit in England whose strata are earliest Cenomanian in age. It lies above the erosive contact between the Gault Formation and the Chalk Group in the vicinity of Cambridgeshire, and technically forms the lowest member bed of the West Melbury Marly Chalk Formation.Cambridge Greensand at BGS It is a remanié deposit, containing reworked fossils of late age, including those of dinosaurs and pterosaurs.

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been 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, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Combinatio Nova
''Combinatio nova'', abbreviated ''comb. nov.'' (sometimes ''n. comb.''), is Latin for "new combination". It is used in taxonomic biology literature when a new name is introduced based on a pre-existing name. The term should not to be confused with ', used for a previously unnamed species. There are three situations: * the taxon is moved to a different genus * an infraspecific taxon is moved to a different species * the rank of the taxon is changed. Examples When an earlier named species is assigned to a different genus, the new genus name is combined with of said species, e.g. when ''Calymmatobacterium granulomatis'' was renamed ''Klebsiella granulomatis'', it was referred to as ''Klebsiella granulomatis comb. nov.'' to denote it was a new combination. See also * Glossary of scientific naming * Basionym * List of Latin phrases * Nomenclature code Nomenclature codes or codes of nomenclature are the various rulebooks that govern biological taxonomic nomenclature, each in the ...

Diogenes De Almeida Campos
Diogenes ( ; grc, Διογένης, Diogénēs ), also known as Diogenes the Cynic (, ) or Diogenes of Sinope, was a Greek philosopher and one of the founders of Cynicism (philosophy). He was born in Sinope, an Ionian colony on the Black Sea coast of Anatolia (Asia Minor''Diogenes of Sinope'' ) in 412 or 404 BC and died at Corinth in 323 BC., Plutarch, ''Moralia'', 717c. says that he died on the same day as Alexander the Great, which puts his death at 323 BC. Diogenes Laërtius's statement that Diogenes died "nearly 90" would put his year of birth at 412 BC. But Censorinus (''De die natali'', 15.2) says that he died at age 81, which puts his year of birth at 404 BC. The Suda puts his birth at the time of the Thirty Tyrants, which also gives 404 BC. Diogenes was a controversial figure. He was allegedly banished, or fled from, Sinope for debasement of currency. He was the son of the mintmaster of Sinope, and there is some debate as to whether or not he alone had debased the S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
