Bergamodactylus
''Bergamodactylus'' is a putative genus of basal pterosaur which lived during the Late Triassic (early Norian) in the area of present-day Bergamo province in Italy. Its only species is ''Bergamodactylus wildi''. It was named in 2015 based on a pterosaur specimen which had previously been regarded as a juvenile '' Eudimorphodon'' or as identical to '' Carniadactylus''. Some Triassic pterosaur specialists consider the distinguishing features of ''Bergamodactylus'' to be invalid or insufficient to distinguish it from ''Carniadactylus'', and thus retain the specimen in that genus. History In 1978, Rupert Wild described a small pterosaur specimen in the collection of the '' Museo di Paleontologia dell´Università di Milano'', found near Cene, Lombardy. He referred to it as the "Milan Exemplar" and identified it as a juvenile of '' Eudimorphodon ranzii''. Wild noted considerable differences with the latter's type specimen but these were explained as reflecting the young age of th ...

Carniadactylus
''Carniadactylus'' is a genus of pterosaur which existed in Europe during the Late Triassic period (late Carnian or early Norian, about 228 million years agoBarrett, P. M., Butler, R. J., Edwards, N. P., & Milner, A. R. (2008). Pterosaur distribution in time and space: an atlas. ''Zitteliana'', 61-107/ref>). The genus contains a single species, ''Carniadactylus rosenfeldi''. Description ''Carniadactylus'' was similar in appearance and anatomy to its close relative ''Eudimorphodon'', though it was significantly smaller. Like ''Eudimorphodon'', it is notable for its complex multi-cusped teeth. Despite their similarities, the size difference between these two pterosaurs likely meant that they occupied different niches and relied on different food sources. This is supported by studies of their teeth. While similar in construction, the teeth of ''Carniadactylus'' show little to no wear, unlike the larger, fish-eating ''Eudimorphodon'', which may have been able to chew its food. The sma ...

Campylognathoidea
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.

Alexander Kellner
Alexander Wilhelm Armin Kellner (born September 26, 1961) is a Brazilian geologist and paleontologist who is a leading expert in the field of studying pterosaurs. His research has focused mainly on fossil reptiles from the Cretaceous Period, including extinct dinosaurs and crocodylomorphs. Kellner has over 500 publications to his name, has published more than 160 primary studies and two science books. He has participated in paleontological expeditions to many locations including Brazil, Chile, Iran, the United States, Argentina, China, and Antarctica. His scientific achievements include the description of more than thirty species. For his work he has received several honors and prizes, including the TWAS Prize for Earth Sciences from The World Academy of Sciences and admission to the National Order of Scientific Merit (class Comendador), one Brazil's most prestigious awards.

Frontal Bone
The frontal bone is a bone in the human skull. The bone consists of two portions.''Gray's Anatomy'' (1918) These are the vertically oriented squamous part, and the horizontally oriented orbital part, making up the bony part of the forehead, part of the bony orbital cavity holding the eye, and part of the bony part of the nose respectively. The name comes from the Latin word ''frons'' (meaning " forehead"). Structure of the frontal bone The frontal bone is made up of two main parts. These are the squamous part, and the orbital part. The squamous part marks the vertical, flat, and also the biggest part, and the main region of the forehead. The orbital part is the horizontal and second biggest region of the frontal bone. It enters into the formation of the roofs of the orbital and nasal cavities. Sometimes a third part is included as the nasal part of the frontal bone, and sometimes this is included with the squamous part. The nasal part is between the brow ridges, and ends in ...

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 for ...

Postorbital Bone
The ''postorbital'' is one of the bones in vertebrate skulls which forms a portion of the dermal skull roof and, sometimes, a ring about the orbit. Generally, it is located behind the postfrontal and posteriorly to the orbital fenestra. In some vertebrates, the postorbital is fused with the postfrontal to create a postorbitofrontal. Birds have a separate postorbital as an embryo, but the bone fuses with the frontal Front may refer to: Arts, entertainment, and media Films * ''The Front'' (1943 film), a 1943 Soviet drama film * ''The Front'', 1976 film Music * The Front (band), an American rock band signed to Columbia Records and active in the 1980s and e ... before it hatches.

Alaunian
The Norian is a division of the Triassic Period. It has the rank of an age (geochronology) or stage (chronostratigraphy). It lasted from ~227 to million years ago. It was preceded by the Carnian and succeeded by the Rhaetian. Stratigraphic definitions The Norian was named after the Noric Alps in Austria. The stage was introduced into scientific literature by Austrian geologist Edmund Mojsisovics von Mojsvar in 1869. The Norian Stage begins at the base of the ammonite biozones of '' Klamathites macrolobatus'' and '' Stikinoceras kerri'', and at the base of the conodont biozones of '' Metapolygnathus communisti'' and '' Metapolygnathus primitius''. A global reference profile for the base (a GSSP) had in 2009 not yet been appointed. The top of the Norian (the base of the Rhaetian) is at the first appearance of ammonite species '' Cochloceras amoenum''. The base of the Rheatian is also close to the first appearance of conodont species '' Misikella spp.'' and '' Epigondolella mo ...

Praemaxilla
The premaxilla (or praemaxilla) is one of a pair of small cranial bones at the very tip of the upper jaw of many animals, usually, but not always, bearing teeth. In humans, they are fused with the maxilla. The "premaxilla" of therian mammal has been usually termed as the incisive bone. Other terms used for this structure include premaxillary bone or ''os premaxillare'', intermaxillary bone or ''os intermaxillare'', and Goethe's bone. Human anatomy In human anatomy, the premaxilla is referred to as the incisive bone (') and is the part of the maxilla which bears the incisor teeth, and encompasses the anterior nasal spine and alar region. In the nasal cavity, the premaxillary element projects higher than the maxillary element behind. The palatal portion of the premaxilla is a bony plate with a generally transverse orientation. The incisive foramen is bound anteriorly and laterally by the premaxilla and posteriorly by the palatine process of the maxilla. It is formed from the f ...
