Lonchodectes
''Lonchodectes'' (meaning "lance biter") was a genus of lonchodectid pterosaur from several formations dating to the Turonian (Late Cretaceous) of England, mostly in the area around Kent.

Lonchodectidae
Lonchodectidae or LonchodraconidaePêgas, R.V., Holgado, B., Leal, M.E.C., 2019. "''Targaryendraco wiedenrothi'' gen. nov. (Pterodactyloidea, Pteranodontoidea, Lanceodontia) and recognition of a new cosmopolitan lineage of Cretaceous toothed pterodactyloids", ''Historical Biology'', 1–15. doi:10.1080/08912963.2019.1690482 is a group of pterosaurs within the clade Pterodactyloidea. It has variously been considered to be within Ctenochasmatoidea, Azhdarchoidea and Pteranodontia.Witton, M.P., Martill, D.M., and Green, M. (2009).

They are notable for their high, conical tooth sockets and raised alveolar margins.

Cimoliopterus
''Cimoliopterus'' is a genus of pterosaur that lived during the Late Cretaceous in what is now England and the United States. The first known specimen, consisting of the front part of a snout including part of a crest, was discovered in the Grey Chalk Subgroup of Kent, England, and described as the new species ''Pterodactylus cuvieri'' in 1851. The specific name ''cuvieri'' honours the palaeontologist George Cuvier, whereas the genus ''Pterodactylus'' was then used for many pterosaur species that are not thought to be closely related today. It was one of the first pterosaurs to be depicted as models in Crystal Palace Park in the 1850s. The species was subsequently assigned to various other genera, including ''Ornithocheirus'' and ''Anhanguera''. In 2013, the species was moved to a new genus, as ''Cimoliopterus cuvieri''; the generic name ''Cimoliopterus'' is derived from the Greek words for "chalk" and "wing". Other specimens and species have also been assigned to or synonymi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithocheirus
''Ornithocheirus'' (from Ancient Greek "ὄρνις", meaning ''bird'', and "χεῖρ", meaning ''hand'') is a pterosaur genus known from fragmentary fossil remains uncovered from sediments in the UK and possibly Morocco. Several species have been referred to the genus, most of which are now considered as dubious species, or members of different genera, and the genus is now often considered to include only the type species, ''Ornithocheirus simus''. Species have been referred to ''Ornithocheirus'' from the mid-Cretaceous period of both Europe and South America, but ''O. simus'' is known only from the UK, though a specimen referred to ''O.'' cf. ''simus'' is also known from Morocco. Because ''O. simus'' was originally named based on poorly preserved fossil material, the genus ''Ornithocheirus'' has suffered enduring problems of zoological nomenclature. Fossil remains of ''Ornithocheirus'' have been recovered mainly from the Cambridge Greensand of England, dating to the beginni ...

Pterodactylus
''Pterodactylus'' (from Greek () meaning 'winged finger') is an extinct genus of pterosaurs. It is thought to contain only a single species, ''Pterodactylus antiquus'', which was the first pterosaur to be named and identified as a flying reptile. Fossil remains of ''Pterodactylus'' have primarily been found in the Solnhofen limestone of Bavaria, Germany, which dates from the Late Jurassic period (early Tithonian stage), about 150.8 to 148.5 million years ago. More fragmentary remains of ''Pterodactylus'' have tentatively been identified from elsewhere in Europe and in Africa. ''Pterodactylus'' was a generalist carnivore that probably fed on a variety of invertebrates and vertebrates. Like all pterosaurs, ''Pterodactylus'' had wings formed by a skin and muscle membrane stretching from its elongated fourth finger to its hind limbs. It was supported internally by collagen fibres and externally by keratinous ridges. ''Pterodactylus'' was a small pterosaur compared to other famo ...

Coloborhynchus
''Coloborhynchus'' is a genus of pterodactyloid pterosaur belonging to the family Anhangueridae, though it has also been recovered as a member of the Ornithocheiridae in some studies. ''Coloborhynchus'' is known from the Lower Cretaceous of England (Valanginian age, 140 to 136 million years ago), and depending on which species are included, possibly the Albian and Cenomanian ages (113 to 93.9 million years ago) as well. ''Coloborhynchus'' was once thought to be the largest known toothed pterosaur, however, a specimen of the closely related ''Tropeognathus'' is now thought to have had a larger wingspan. History and classification Like many ornithocheiroid pterosaurs named during the 19th century, ''Coloborhynchus'' has a highly convoluted history of classification. Over the years numerous species have been assigned to it, and often, species have been shuffled between ''Coloborhynchus'' and related genera by various researchers. In 1874 Richard Owen, rejecting the creation by H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amblydectes
''Amblydectes'' is a genus of pterosaur known from jaw fragments. It apparently had a jaw flattened towards the tip and triangular in cross-section. It has at times been synonymized with ''Coloborhynchus'', ''Criorhynchus'', ''Lonchodectes'', or ''Ornithocheirus''. A 2013 study found ''A. crassidens'' and ''A. eurygnathus'' to be ''nomina dubia'', with ''A. platystomus'' possibly belonging to a separate, yet unnamed genus. A 2021 study found ''A. crassidens'' to be a valid genus within Anhangueridae, while ''A. platystomus'' was placed in the new genus ''Draigwenia''. ''A. eurygnathus'' was found to possibly be a junior synonym of ''A. crassidens''.

Ornithostoma
''Ornithostoma'' (meaning "bird mouth") is a genus of pterodactyloid pterosaur that lived during the Early Cretaceous period (Albian stage) of Europe, around 110 million years ago. ''Ornithostoma'' was once thought to have been a senior synonym of the pteranodontid ''Pteranodon'' due to its toothless anatomy and prior naming. History In 1869, Harry Govier Seeley, cataloguing the fossils of the Sedgwick Museum at Cambridge, referred three snout fragments of toothless pterosaur specimens from the Lower Cretaceous Albian Cambridge Greensand of England to ''Ornithocheirus simus''. These fragments had in 1859 been described by Richard Owen (who considered the later holotype jaw fragment part of a metacarpal) and referred to ''Pterodactylus sedgwickii'' and ''Pterodactylus fittoni''. By 1871 Seeley had realised ''Ornithocheirus simus'' was a toothed form, different from the fragments. Therefore, he provisionally named them as a separate genus ''Ornithostoma'', the name derived from G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

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.
