Anhanguera was a fish-eating animal with a wingspan of about 4.6 meters (15 ft). [3] Like many other anhanguerids, Anhanguera had rounded crests at front of its upper and lower jaws, which were filled with angled, conical but curved teeth of various sizes and orientations. Like many of its relatives, the jaws were tapered in width, but expanded ...

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 to Late Cretaceous periods (Valanginian to Turonian stages), around 140 to 92.5 million years ago.
For the majority of pterosaur species, it is not known whether they practiced any form of parental care, but their ability to fly as soon as they emerged from the egg and the numerous flaplings found in environments far from nests and alongside adults has led most researchers, including Christopher Bennett and David Unwin, to conclude that the ...
Holotype specimen of Tropeognathus mesembrinus (BSP 1987 I 46) in lateral (A1), palatal (A2), and anterior (A3) views. In the 1980s the German paleontology museum Bayerische Staatssammlung für Paläontologie und historische Geologie in Munich acquired a pterosaur skull from Brazilian fossil dealers that had probably been found in Ceará, in the geological group called the Santana Group, which ...
Archaeornithes, extinct primitive flying bird-like dinosaurs, e.g. Archaeopteryx; Neornithes, modern birds which are the only surviving dinosaurs; Scansoriopterygidae, an extinct family of climbing and gliding dinosaurs; Other (extinct) members of the clade Avialae, perhaps also other Maniraptorans
Quetzalcoatlus (/ k ɛ t s əl k oʊ ˈ æ t l ə s /) is a genus of azhdarchid pterosaur that lived during the Maastrichtian age of the Late Cretaceous in North America. The type specimen, recovered in 1971 from the Javelina Formation of Texas, United States, consists of several wing fragments and was described as Quetzalcoatlus northropi in 1975 by Douglas Lawson.
Avemetatarsalia (meaning "bird metatarsals") is a clade of diapsid reptiles containing all archosaurs more closely related to birds than to crocodilians. [2] The two most successful groups of avemetatarsalians were the dinosaurs and pterosaurs.
