Aussiedraco
''Aussiedraco'' is a genus of targaryendraconian pterodactyloid pterosaur from the early Cretaceous of Australia. Description ''Aussiedraco'' is known from holotype QM F10613, a partial mandibular symphysis housed at the Queensland Museum, recovered from rocks of the Toolebuc Formation, about 70 km east of Boulia, western Queensland, dating to Albian stage. It was named by Alexander W.A. Kellner, Taissa Rodrigues and Fabiana R. Costa in 2011 and the type species is ''Aussiedraco molnari''. The generic name is derived from "Aussie", a shortened form of Australian, and "draco", from Latin meaning dragon. The specific epithet honours Ralph E. Molnar, who first described the specimen in 1980. The symphysis fragment is 88 millimetres long and very straight and narrow, with a lanceolate not-expanded tip and triangular cross-section. It lacks a keel or crest and is convex on top, with a median narrow deep groove not reaching the tip, but flat at the bottom. As far as can ...

Lanceodontian
Ornithocheiromorpha (from Ancient Greek, meaning "bird hand form") is a group of pterosaurs within the suborder Pterodactyloidea. Fossil remains of this group date back from the Early Cretaceous, Early to Late Cretaceous Period (geology), periods (Valanginian to Turonian stages), around 140 to 92.5 million years ago. Ornithocheiromorphs were discovered worldwide except Antarctica, though most genera were recovered in Europe, Asia and South America. They were the most diverse and successful pterosaurs during the Early Cretaceous, but throughout the Late Cretaceous they were replaced by better adapted and more advanced pterosaur species such the pteranodontids and azhdarchoids. The Ornithocheiromorpha was defined in 2014 by Andres and colleagues, and they made Ornithocheiromorpha the most inclusive clade containing ''Ornithocheirus'', but not ''Pteranodon''. Ornithocheiromorphs are considered to be some of the largest animals to have ever flown. Members of this group are also rega ...

Targaryendraconia
Targaryendraconia is an extinct clade of lanceodontian pterosaurs that lived from the Early to Late Cretaceous period in Europe, North America, South America, and Australia. Classification Below is a cladogram following a topology by Pêgas and colleagues in 2019. In their analysis, they recovered Targaryendraconia as the sister taxon of the clade Anhangueria, both of which are within the more inclusive group Ornithocheirae. Targaryendraconia is split into two families: the Targaryendraconidae, which contains ''Aussiedraco'', '' Barbosania'', and ''Targaryendraco'', and the Cimoliopteridae, which contains ''Aetodactylus'', ''Camposipterus ''Camposipterus'' is a genus of pterodactyloid pterosaur from the Early Cretaceous of England.

Toolebuc Formation
The Toolebuc Formation is a geological formation that extends from Queensland across South Australia and the Northern Territory in Australia, whose strata date back to the Albian stage of the Early Cretaceous. Dinosaurs,Weishampel ''et al.'', 2004, pp.573-574 pterosaurs, plesiosaurs, ichthyosaurs, protostegid turtles, sharks, chimaeroids and bony fish remains are among the fossils that have been recovered from the formation. Description Deposition occurred in a cool to temperate inland sea setting and the present lithology is dominantly made up of limey shales with abundant ''Inoceramus'' bivalve shells. Ichthyosaurs and protostegid turtles were the most common marine reptiles at this time in the Eromanga Sea, in contrast to older Aptian deposits such as the Bulldog Shale of South Australia, which show that plesiosaurs were previously more abundant and also more diverse. The Toolebuc Formation is one of the richest known sources of Mesozoic vertebrate fossils in Australia, with ...

Pterodactyloid
Pterodactyloidea (derived from the Greek words ''πτερόν'' (''pterón'', for usual ''ptéryx'') "wing", and ''δάκτυλος'' (''dáktylos'') "finger" meaning "winged finger", "wing-finger" or "finger-wing") is one of the two traditional suborders of pterosaurs ("wing lizards"), and contains the most derived members of this group of flying reptiles. They appeared during the middle Jurassic Period, and differ from the basal (though paraphyletic) rhamphorhynchoids by their short tails and long wing metacarpals (hand bones). The most advanced forms also lack teeth, and by the late Cretaceous, all known pterodactyloids were toothless. Many species had well-developed crests on the skull, a form of display taken to extremes in giant-crested forms like ''Nyctosaurus'' and ''Tupandactylus''. Pterodactyloids were the last surviving pterosaurs when the order became extinct at the end of the Cretaceous Period, together with the non-avian dinosaurs and most marine reptiles. "Pteroda ...

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 Kerguelen P ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Dragon
A dragon is a reptilian legendary creature that appears in the folklore of many cultures worldwide. Beliefs about dragons vary considerably through regions, but dragons in western cultures since the High Middle Ages have often been depicted as winged, horned, and capable of breathing fire. Dragons in eastern cultures are usually depicted as wingless, four-legged, serpentine creatures with above-average intelligence. Commonalities between dragons' traits are often a hybridization of feline, reptilian and avian features. Scholars believe huge extinct or migrating crocodiles bear the closest resemblance, especially when encountered in forested or swampy areas, and are most likely the template of modern Oriental dragon imagery. Etymology The word ''dragon'' entered the English language in the early 13th century from Old French ''dragon'', which in turn comes from la, draconem (nominative ) meaning "huge serpent, dragon", from Ancient Greek , (genitive , ) "serpent, giant s ...

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 ...

Pteranodontoidea
Pteranodontoidea (or pteranodontoids, from Greek meaning "toothless wings") is an extinct clade of ornithocheiroid pterosaurs from the Early to Late Cretaceous (early Valanginian to late Maastrichtian stages) of Asia, Africa, Europe, North America and South America. It was named by Alexander Wilhelm Armin Kellner in 1996. In 2003, Kellner defined the clade as a node-based taxon consisting of the last common ancestor of ''Anhanguera'', ''Pteranodon'' and all its descendants. The clade Ornithocheiroidea is sometimes considered to be the senior synonym of Pteranodontoidea, however it depends on its definition.Unwin, D. M., (2003): On the phylogeny and evolutionary history of pterosaurs. pp. 139-190. — ''in'' Buffetaut, E. & Mazin, J.-M., (eds.): ''Evolution and Palaeobiology of Pterosaurs''.

Mythunga
''Mythunga'' is a genus of anhanguerid pterosaur from the late Early Cretaceous of Australia. Fossil remains of ''Mythunga'' dated back to the Albian stage of the Early Cretaceous, and the animal itself was found to be a close relative of another Australian anhanguerid called ''Ferrodraco''. Discovery and naming ''Mythunga'' is known from a partial skull, holotype QM F18896 found in April 1991 by Philip Gilmore in marine rocks of the late Albian-age Toolebuc Formation at Dunluce Station west of Hughenden, Queensland. Only the middle snout and corresponding parts of the lower jaws are known, including the rear of a left premaxilla, the lower parts of both maxillae, the rear dentaries and a right splenial. They were three-dimensionally preserved, associated in a chalk nodule. It represents a subadult individual. The fossil was prepared by Angela Hatch of the Queensland Museum, both by mechanical means and by an acid bath. The type species ''Mythunga camara'' was named and descri ...
