Peteinosaurus Zambellii
''Peteinosaurus'' ( ; meaning "winged lizard") was a prehistoric genus of pterosaur. It lived in the late Triassic period in the late Norian age (about 221 to 210 million years ago), and at a wingspan of around , was one of the smallest and earliest pterosaurs, although other estimates suggest a wingspan of up to . Discovery Three fossils have been found near Cene, Italy. The first fossil, the holotype MCSNB 2886, is fragmentary and disarticulated. The second, the articulated paratype MCSNB 3359, lacks any diagnostic features of ''Peteinosaurus'' and thus might be a different species. This paratype has a long tail (20 cm) made more stiff by long extensions of the vertebrae; this feature is common among pterosaurs of the Triassic. The third example is MCSNB 3496, another fragmentary skeleton. All specimens are those of subadults and of none has the skull been preserved. Like most pterosaurs, ''Peteinosaurus'' had bones that were strong but very light. ''Peteinosaurus'' is t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, Ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful sandstone'')'', t ...

Pteranodon
''Pteranodon'' (); from Ancient Greek (''pteron'', "wing") and (''anodon'', "toothless") is a genus of pterosaur that included some of the largest known flying reptiles, with ''P. longiceps'' having a wingspan of . They lived during the late Cretaceous geological period of North America in present-day Kansas, Nebraska, Wyoming, South Dakota and Alabama. More fossil specimens of ''Pteranodon'' have been found than any other pterosaur, with about 1,200 specimens known to science, many of them well preserved with nearly complete skulls and articulated skeletons. It was an important part of the animal community in the Western Interior Seaway. ''Pteranodon'' was not a dinosaur. By definition, all dinosaurs belong to the group Dinosauria; ''Pteranodon'' belongs to the group Pterosauria. Nonetheless, ''Pteranodon'' is the most famous pterosaur, frequently featured in dinosaur media and strongly associated with dinosaurs by the general public. While not dinosaurs, pterosaurs such as ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coelophysis And Peteinosaurus
''Coelophysis'' ( traditionally; or , as heard more commonly in recent decades) is an extinct genus of coelophysid theropod dinosaur that lived approximately 228 to 201.3 million years ago during the latter part of the Triassic Period from the Carnian and Rhaetian faunal stages in what is now the southwestern United States. ''Megapnosaurus'' was once considered a species within this genus,Weishampel, David B; et al. (2004). "Dinosaur distribution (Early Jurassic, Africa)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 535–536. but this interpretation has been challenged since 2017 and the genus ''Megapnosaurus'' is now considered valid. ''Coelophysis'' was a small, slenderly-built, ground-dwelling, bipedal carnivore that could grow up to long. It is one of the earliest known dinosaur genera. Scattered material representing similar animals has been found worldwide in some Late Tri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austriadactylus
''Austriadactylus'' is a genus of "rhamphorhynchoid" pterosaur. The fossil remains were unearthed in Late Triassic (middle Norian ageBarrett, P. M., Butler, R. J., Edwards, N. P., & Milner, A. R. (2008). Pterosaur distribution in time and space: an atlas. ''Zitteliana'', 61-107/ref>) rocks of Austria. The genus was named in 2002 by Fabio Marco Dalla Vecchia e.a.. The type species is ''Austriadactylus cristatus''. The genus name is derived from Latin ''Austria'' and Greek ''daktylos'', "finger", in reference to the wing finger of pterosaurs. The specific epithet means "crested" in Latin, a reference to the skull crest. The genus is based on holotype SMNS 56342, a crushed partial skeleton on a slab, found in an abandoned mine near Ankerschlag in Tyrol, in the Norian Seefelder Beds. The counterslab has been lost and with it some of the bone. The fossil consists of the skull, lower jaws, some vertebrae, parts of the limbs and pelvic girdle, and the first part of the tail.

Lonchognatha
Novialoidea (meaning "new wings") is an extinct clade of macronychopteran pterosaurs that lived from the latest Early Jurassic to the latest Late Cretaceous (early Toarcian to late Maastrichtian ageBarrett, P. M., Butler, R. J., Edwards, N. P., & Milner, A. R. (2008). Pterosaur distribution in time and space: an atlas. ''Zitteliana'', 61-107/ref>), their fossils having been found on all continents except Antarctica. History and classification Novialoidea was named by paleontologist Alexander Wilhelm Armin Kellner in 2003 as a node-based taxon consisting of the last common ancestor of ''Campylognathoides'', '' Quetzalcoatlus'' and all its descendants. This name was derived from Latin ''novus'' "new", and ''ala'', "wing", in reference to the wing synapomorphies that the members of the clade possess.Kellner, A. W.

Junior Synonym
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia lev ...

David Unwin
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, David c ...

Fabio Marco Dalla Vecchia
Fabio is a given name descended from Latin ''Fabius'' and very popular in Italy and Latin America (due to Italian migration). Its English equivalent is Fabian. The name is written without an accent in Italian and Spanish, but is usually accented in Portuguese as ''Fábio'' (with the diminutive Fabinho or Fabiano). The presence or absence of the written accent does not affect pronunciation.

Cladistic
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a 'grade', which are fruitless to precisely delineate, especially when including extinct species. R ...

Dimorphodon
''Dimorphodon'' was a genus of medium-sized pterosaur from the early Jurassic Period. It was named by paleontologist Richard Owen in 1859. ''Dimorphodon'' means "two-form tooth", derived from the Greek (') meaning "two", (') meaning "shape" and (') meaning "tooth", referring to the fact that it had two distinct types of teeth in its jaws – which is comparatively rare among reptiles. ''Dimorphodon'' inhabited Europe. Description The body structure of ''Dimorphodon'' displays many "primitive" characteristics, such as, according to Owen, a very small brain-pan and proportionally short wings. The first phalanx in its flight finger is only slightly longer than its lower arm. The neck was short but strong and flexible and may have had a membranous pouch on the underside. The vertebrae had pneumatic foramina, openings through which the air sacs could reach the hollow interior. ''Dimorphodon'' had an adult body length of long, with a 1.45 metre (4.6 ft) wingspan.

Vertebrate Paleontology And Evolution
''Vertebrate Paleontology and Evolution'' is an advanced textbook on vertebrate paleontology by Robert L. Carroll, published in 1988 by WH Freeman. It provides a very detailed technical account of various groups of living and fossil vertebrates. The book, which is written in the style of Alfred Sherwood Romer's ''Vertebrate Paleontology'', presented more recent overall coverage of the subject. At the rear of the book is a 53-page Classification list which lists every genus known at the time of publication, along with locality and stratigraphic range. ''Vertebrate Paleontology and Evolution'' appeared in print in 1988, just before the cladistic taxonomy became popular in vertebrate paleontology. The books thus uses the classical systematic scheme, including a number of paraphyletic taxa that are not recognised under phylogenetic nomenclature Phylogenetic nomenclature is a method of nomenclature for taxa in biology that uses phylogenetic definitions for taxon names as explaine ...
