Longchengornis Sanyanensis
''Longchengornis'' is a genus of enantiornithean birds which lived during the early Cretaceous Period, about 120 mya, and is known from a fossil found in the Jiufotang Formation in Liaoning province, People's Republic of China. It contains the single species ''L. sanyanensis'', though some researchers believe this to be a synonym of the similar species ''Cathayornis yandica''.Zhou Z. and Wang Y. (2010). "Vertebrate diversity of the Jehol Biota as compared with other lagerstätten." ''Science China: Earth Sciences'', 53(12): 1894–1907. Discovery and etymology The type species ''Longchengornis sanyanensis'' was named and described in 1997 by Hou Lianhai. The generic name ''Longchengornis'' combines the older name of Chaoyang, Longcheng or "Dragon City", with a Greek ''ornis'', "bird". The specific name refers to the Sanyan, the "Three Yan" as the discovery was made on the former territory of the three Yan kingdoms: the Former Yan, the Later Yan and the Northern Yan. Descri ...

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 Kergue ...

Chaoyang, Liaoning
Chaoyang () is a prefecture-level city in western Liaoning province, People's Republic of China. With a vast land area of almost , it is by area the largest prefecture-level city in Liaoning, and borders on Hebei province and the Inner Mongolia Autonomous Region to the west. The area under Chaoyang's jurisdictional control is split up into two counties (Jianping, Chaoyang), two urban districts (Longcheng, Shuangta), two county-level cities (Beipiao, Lingyuan), and the Harqin Left Wing Mongolian Autonomous County. The total regional population is 3 million, while the urban centre where the government office is located has a population of 430,000 and forms the core of Chaoyang. Known as China's 'fossil city', many important paleontological discoveries have been made in Chaoyang, and the Harqin region is the oldest currently known prehistoric site in northern China. Two of the most remarkable Early Cretaceous birds known to date were recovered in the vicinity of the Jiufotang Fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bird Genera
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimmi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 necessaril ...

Northern Yan
Yan, known in historiography as the Northern Yan (; 407 or 409–436), Eastern Yan () or Huanglong (), was a dynastic state of China during the era of Sixteen Kingdoms. Some historians consider Gao Yun, a member of the Goguryeo royal family, to be the first Northern Yan monarch, while others consider Feng Ba of Han ethnicity to be the founder. Original from the University of California Rulers of the Northern Yan See also *Xianbei The Xianbei (; ) were a Proto-Mongolic ancient nomadic people that once resided in the eastern Eurasian steppes in what is today Mongolia, Inner Mongolia, and Northeastern China.

Former Yan
The Former Yan (; 337–370) was a dynastic state ruled by the Xianbei during the era of Sixteen Kingdoms in China. Initially, Murong Huang and his son Murong Jun claimed the Jin dynasty-created title "Prince of Yan," but subsequently, in 352, after seizing most of the former Later Zhao territory, Murong Jun would declare himself emperor, and after that point, the rulers of the Former Yan declared themselves "emperors". History During the winter of 342, the Xianbei of Former Yan, ruled by the Murong clan, attacked and destroyed Goguryeo's capital, Hwando, capturing 50,000 Goguryeo men and women to use as slave labor in addition to taking the queen mother and queen prisoner, and forced King Gogukwon to flee for a while. The Xianbei also devastated Buyeo in 346, accelerating Buyeo migration to the Korean peninsula. Their capital was Yan (Beijing) in 350, then Yecheng in 357, and finally Luoyang in 364.

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term fo ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

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.
