List Of Informally Named Pterosaurs
This list of informally named pterosaurs is a list of pterosaurs that have not been formally published. This can include unavailable names that have not been published under a valid name. The following types of invalid names are present: *''Nomen nudum, Latin "naked name"'': names which have been included in print, yet not properly published according to the standards set by the International Commission on Zoological Nomenclature. The plural form, ''nomina nudia'' are not considered valid, and are not italicized as valid names are. *''Nomen manuscriptum, Latin "manuscript name"'': A name which has appeared in a manuscript that has not been published, but intends to be. They are equivalent to ''nomen nudum'', except for the method of publication and description. *Informal nicknames assigned by the press or researchers. P Pricesaurus "''Pricesaurus megalodon''" ("Llewellyn Ivor Price lizard") is a ''nomen nudum'' based on remains currently assigned to ''Anhanguera''. The remains were ...

Unavailable Names
In zoological nomenclature, an unavailable name is a name that does not conform to the rules of the International Code of Zoological Nomenclature and that therefore is not available for use as a valid name for a taxon. Such a name does not fulfil the requirements in Articles 10 through 20 of the Code, or is excluded under Article 1.3. Unavailable names include names that have not been validly published, such as "''Oryzomys hypenemus''", names without an accompanying description (''nomina nuda''), such as the subgeneric name ''Micronectomys'' proposed for the Nicaraguan rice rat, names proposed with a rank below that of subspecies (infrasubspecific names), such as ''Sorex isodon princeps montanus'' for a form of the taiga shrew The taiga shrew (''Sorex isodon''), also known as the even-toothed shrew can achieve a body length of about 67 millimeters, with a tail of about 43 millimeters. This shrew is very similar to the long-clawed shrew. This species inhabits forested m ...,Huttere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nomen Nudum
In taxonomy, a ''nomen nudum'' ('naked name'; plural ''nomina nuda'') is a designation which looks exactly like a scientific name of an organism, and may have originally been intended to be one, but it has not been published with an adequate description. This makes it a "bare" or "naked" name, which cannot be accepted as it stands. A largely equivalent but much less frequently used term is ''nomen tantum'' ("name only"). In zoology According to the rules of zoological nomenclature a ''nomen nudum'' is unavailable; the glossary of the '' International Code of Zoological Nomenclature'' gives this definition: And among the rules of that same Zoological Code: In botany According to the rules of botanical nomenclature a ''nomen nudum'' is not validly published. The glossary of the ''International Code of Nomenclature for algae, fungi, and plants'' gives this definition: The requirements for the diagnosis or description are covered by articles 32, 36, 41, 42, and 44.

International Commission On Zoological Nomenclature
The International Commission on Zoological Nomenclature (ICZN) is an organization dedicated to "achieving stability and sense in the scientific naming of animals". Founded in 1895, it currently comprises 26 commissioners from 20 countries. Organization The ICZN is governed by the "Constitution of the ICZN", which is usually published together with the ICZN Code. Members are elected by the Section of Zoological Nomenclature, established by the International Union of Biological Sciences (IUBS). The regular term of service of a member of the Commission is six years. Members can be re-elected up to a total of three full six-year terms in a row. After 18 continuous years of elected service, a break of at least three years is prescribed before the member can stand again for election. Activities Since 2014, the work of the Commission is supported by a small secretariat based at the National University of Singapore, in Singapore. Previously, the secretariat was based in London and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Llewellyn Ivor Price
Llewellyn Ivor Price (October 9, 1905 – June 9, 1980) was one of the first Brazilian paleontologists. His work contributed not only to the development of Brazilian but also to global paleontology. He collected ''Staurikosaurus'', the first dinosaur discovered in Brazil. Biography Price was born in Santa Maria. The son of American parents, he studied chemistry and graduated in zoology and geology in the United States. After being professor at Harvard he returned to Brazil. He died of a heart attack in Rio Grande do Sul. Awards * In 1980 he was awarded the ''José Bonifácio de Andrada e Silva'' prize by the Sociedade Brasileira de Geologia The Sociedade Brasileira de Geologia is a learned society, technical and scientific society that aims brings to bring together Brazilian geologists, to disseminate technical and scientific information, and to participate in national decisions invo ....http://www.sbgeo.org.br/index.php/sbgeo/realizacoes Sociedade Brasileira de Geologia: ...

Anhanguera (pterosaur)
''Anhanguera'' () is a genus of pterodactyloid pterosaur known from the Early Cretaceous (Albian age, 125 to 112 million years ago) Romualdo Formation of Brazil and the Late Cretaceous ( Cenomanian age, 98 to 92.5 million years ago) Kem Kem Group of Morocco. This pterosaur is closely related to ''Ornithocheirus'', but belongs in the family Anhangueridae.Campos, D. de A., and Kellner, A. W. (1985). "Um novo exemplar de ''Anhanguera blittersdorffi'' (Reptilia, Pterosauria) da formação Santana, Cretaceo Inferior do Nordeste do Brasil." In Congresso Brasileiro de Paleontologia, Rio de Janeiro, Resumos, p. 13. The generic name comes from the Tupi words ''añanga'', meaning "spirit protector of the animals" + ''wera'' "bygone". Description ''Anhanguera'' was a fish-eating animal with a wingspan of about .Aureliano, T., Ghilardi, A. M., Duque, R. R., & Barreto, A. M. (2014).

Saraiki Language
Saraiki ( '; also spelt Siraiki, or Seraiki) is an Indo-Aryan language of the Lahnda group, spoken by 26 million people primarily in the south-western half of the province of Punjab in Pakistan. It was previously known as Multani, after its main dialect. Saraiki has partial mutual intelligibility with Standard Punjabi, and it shares with it a large portion of its vocabulary and morphology. At the same time in its phonology it is radically different (particularly in the lack of tones, the preservation of the voiced aspirates and the development of implosive consonants), and has important grammatical features in common with the Sindhi language spoken to the south. The Saraiki language identity arose in the 1960s, encompassing more narrow local earlier identities (like Multani, Derawi or Riasati), and distinguishing itself from broader ones like that of Punjabi. Name The present extent of the meaning of ' is a recent development, and the term most probably gained its cur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maastrichtian
The Maastrichtian () is, in the ICS geologic timescale, the latest age (uppermost stage) of the Late Cretaceous Epoch or Upper Cretaceous Series, the Cretaceous Period or System, and of the Mesozoic Era or Erathem. It spanned the interval from . The Maastrichtian was preceded by the Campanian and succeeded by the Danian (part of the Paleogene and Paleocene). The Cretaceous–Paleogene extinction event (formerly known as the Cretaceous–Tertiary extinction event) occurred at the end of this age. In this mass extinction, many commonly recognized groups such as non-avian dinosaurs, plesiosaurs and mosasaurs, as well as many other lesser-known groups, died out. The cause of the extinction is most commonly linked to an asteroid about wide colliding with Earth, ending the Cretaceous. Stratigraphic definitions Definition The Maastrichtian was introduced into scientific literature by Belgian geologist André Hubert Dumont in 1849, after studying rock strata of the ...
