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. Brian Andres (2008, 2010, 2014) in his analyses, converts Ornithocheiroidea using the definition of Kellner (2003) to avoid this synonymy. Despite the meaning of the group's name, not all pteranodontoids were toothless, the earlier genera such as the istiodactylids and anhanguerids had teeth that they used to catch prey, and several conclusions had led to the idea that they later evolved into the toothless pteranodontids. Pteranodontoids were also the most diverse group of pterosaurs throughout the Cretaceous period, and therefore the most successful flyers during their time. They were mostly replaced by the larger azhdarchids at the end of the Late Cretaceous however, which resulted in resource and terrain competitions, but even so, pteranodontoids still managed to thrive with them, and genera such as Alcione, Barbaridactylus, and Simurghia lived until the Cretaceous-Paleogene extinction event. Pteranodontoids had similar a similar diet to modern-day soaring birds such the albatross, which mainly consisted of fish. Some genera of this group however, fed mainly on carrion, this can be seen on the earlier genera such as Istiodactylus. They were also known for their proportionally large wingspans, the largest recorded of any pteranodontoid reached , and it belongs to the genus Tropeognathus. Several fossil remains were found in the Chalk Formation of England, a chalk pit known for its wide variety of fossils belonging to different animals.

Lonchodraco
Lonchodraco is a genus of lonchodraconid pterodactyloid pterosaur from the Late Cretaceous of southern England. The genus includes species that were previously assigned to other genera. In 1846, James Scott Bowerbank named and described some remains found in a chalk pit at Burham near Maidstone in Kent, as a new species of Pterodactylus: Pterodactylus giganteus. The specific name means "the gigantic one" in Latin. The same pit generated remains of Pterodactylus cuvieri.
