Taveirosaurus
''Taveirosaurus'' (meaning " Taveiro lizard") is a genus of possibly eutriconodontan mammal from the Late Cretaceous Argilas de Aveiro Formation of Portugal, and also Laño, Spain. The genus is based solely on teeth, and the type species is ''T. costai''. Discovery and naming In 1968, Miguel Telles Antunes and Giuseppe Manuppella uncovered fossils at the ''Cerâmica do Mondego'' quarry near Taveiro, a village in Portugal, southwest of Coimbra. Among them were a number of low triangular teeth of a herbivorous dinosaur. In 1991 these were named and described by Telles Antunes and Denise Sigogneau-Russell as the type species, ''Taveirosaurus costai''. The generic name refers to Taveiro. The specific name honours the Portuguese geologist João Carrington da Costa.M. Telles Antunes & D.

Trimucrodon
''Trimucrodon'' is a genus of ornithischian dinosaur from the Late Jurassic Lourinhã Formation of Portugal. The type, and currently only, species is ''T. cuneatus''. Discovery and naming Three isolated teeth found at the Porto Dinheiro (or Pinhiero) locality in the Lisboa District of Portugal were given the name in 1973 by Richard A. Thulborn, derived from the Latin words for "three" and a dagger point, and , and the Ancient Greek word for "tooth". The only species in the taxon is ''Trimucrodon cuneatus'', taken from the wedge shape of the teeth. Though the unit the specimens came from was originally unnamed, it was referred to the Alcobaça, and then Lourinhã Formations, specifically the late Kimmeridgian Amoreira–Porto Novo Member. The type specimen, uncovered between 1962 and 1967 by German zoologist and paleontologist Georg Krusat, is distinguished by prominent denticles at the front and rear ends of the crown, and comes from an individual under long.G.

Eutriconodonta
Eutriconodonta is an order (biology), order of early mammals. Eutriconodonts existed in Asia (including Insular India, pre-contact India), Africa, Europe, North America, North and South America during the Jurassic and the Cretaceous periods. The order was named by Kermack ''et al.'' in 1973 as a replacement name for the paraphyletic Triconodonta. Traditionally seen as the classical Mesozoic small mammalian insectivores, discoveries over the years have shown them to be among the best examples of the diversity of mammals in this time period, including a vast variety of bodyplans, ecological niches and locomotion methods. Classification "Triconodonta" had long been used as the name for an order of early mammals which were close relatives of the ancestors of all present-day mammals, characterized by molar teeth with three main cusps on a crown that were arranged in a row. The group originally included only the family Triconodontidae and taxa that were later assigned to the separate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithischia
Ornithischia () is an extinct clade of mainly herbivorous dinosaurs characterized by a pelvic structure superficially similar to that of birds. The name ''Ornithischia'', or "bird-hipped", reflects this similarity and is derived from the Greek stem ' (), meaning "bird", and ' (), meaning "hip". However, as theropod dinosaurs, birds are only distantly related to this group. Ornithischians with well known anatomical adaptations include the ceratopsians or "horn-faced" dinosaurs (e.g. ''Triceratops''), the pachycephalosaurs or "thick-headed" dinosaurs, the armored dinosaurs ( Thyreophora) such as stegosaurs and ankylosaurs, and the ornithopods. There is strong evidence that certain groups of ornithischians lived in herds, often segregated by age group, with juveniles forming their own flocks separate from adults. Some were at least partially covered in filamentous (hair- or feather- like) pelts, and there is much debate over whether these filaments found in specimens of '' Ti ...

Laño
Laño () is a hamlet and '' concejo'' (a small administrative subdivision) in Condado de Treviño within the Treviño enclave; which is administratively part of the Spanish province of Burgos, but which is completely surrounded by the territory of the Basque country province of Álava. It is best known for the fossils of extinct vertebrates dating from around 70 million years before present which have been found there. Las Gobas, a site of ancient artificial caves from the 7th to the 13th century CE, is located just north of the village. Palaeontology The Paleontology Unit of the University of the Basque Country and other scientists have studied the fossil record at Laño. The fossils are from the late Cretaceous ( late Campanian to lower Maastrichtian). It has been inferred that there was then a braided riverbed at the site, that the sea was nearby, and that the climate was tropical or sub-tropical.

Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism 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 and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...

Nomen Dubium
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium,'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5.

David B
David Robert Jones (8 January 194710 January 2016), known as David Bowie ( ), was an English singer, songwriter and actor. Regarded as one of the most influential musicians of the 20th century, Bowie was acclaimed by critics and musicians, particularly for his innovative work during the 1970s. His career was marked by reinvention and visual presentation, and his music and stagecraft have had a great impact on popular music. Bowie studied art, music and design before embarking on a professional career as a musician in 1963. He released a string of unsuccessful singles with local bands and David Bowie (1967 album), a self-titled solo album (1967) before achieving his first top-five entry on the UK singles chart with "Space Oddity" (1969). After a period of experimentation, he re-emerged in 1972 during the glam rock era with the alter ego Ziggy Stardust (character), Ziggy Stardust. The success of the single "Starman (song), Starman" and its album ''The Rise and Fall of Ziggy Star ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alocodon
''Alocodon'' is a genus of ornithischian dinosaur known from multiple teeth from the Middle or Late Jurassic Cabaços Formation of Portugal, and also the Forest Marble and Chipping Norton Formations of England. A single species is known, ''A. kuehnei''. Discovery and naming The taxon was first described in 1973 by Richard A. Thulborn for an assemblage of teeth from the Pedrógão locality of Portugal, distinguished by an enlarged central denticle on the teeth, with the name taken from the Greek ''alox'' and ''odon'' meaning 'furrow tooth'. The type specimen, a single tooth, is stored in the Museu Geológico do Instituto Geológico e Mineiro in Lisbon, Portugal, formerly having been kept in the collections of the Free University of Berlin as IPFUB P X 1, and comes from an individual under in length. Though it was originally described as having been found in an unnamed deposit in the Portuguese Leiria District of upper Callovian age, it was identified as having come from th ...

Peter Galton
Peter Malcolm Galton (born 14 March 1942 in London) is a British vertebrate paleontologist who has to date written or co-written about 190 papers in scientific journals or chapters in paleontology textbooks, especially on ornithischian and prosauropod dinosaurs. With Robert Bakker in a joint article published in ''Nature'' in 1974, he argued that dinosaurs constitute a natural monophyletic group, in contrast to the prevailing view that considered them polyphyletic and consisting of two different unrelated orders Order, ORDER or Orders may refer to: * A socio-political or established or existing order, e.g. World order, Ancien Regime, Pax Britannica * Categorization, the process in which ideas and objects are recognized, differentiated, and understood * H ..., thus initiating a revolution in dinosaur studies and contributing to the revival of the popularity of dinosaurs in the field of paleontology.

Nodosauridae
Nodosauridae is a family of ankylosaurian dinosaurs known from the Late Jurassic to the Late Cretaceous periods in what is now Asia, Europe, North America, and possibly South America. While traditionally regarded as a monophyletic clade as the sister taxon to the Ankylosauridae, some analyses recover it as a paraphyletic grade leading to the ankylosaurids. Description Nodosaurids, like their sister group the ankylosaurids, were heavily armored dinosaurs adorned with rows of bony armor nodules and spines (osteoderms), which were covered in keratin sheaths. Ankylosaurians were small- to large-sized, heavily built, quadrupedal, herbivorous dinosaurs, possessing small, leaf-shaped teeth. Unlike ankylosaurids, nodosaurids lacked mace-like tail clubs and instead had more flexible tail tips. Many nodosaurids had spikes projecting outward from their shoulders. One particularly well-preserved nodosaurid "mummy", the holotype of '' Borealopelta markmitchelli'', preserves a nearly comple ...
