The Pteranodontidae are a family of large pterosaurs from the Late Cretaceous of North America and possibly other continents including Europe and Africa. The family was named in 1876 by Othniel Charles Marsh. Pteranodontids had a distinctive, elongated crest jutting from the rear of the head (most famously seen in Pteranodon itself).
The split between dinosaurs and pterosaurs occurred just after aphanosaurs branched off the archosaur family tree. This split corresponds to the subgroup Ornithodira (Ancient Greek ὄρνις (órnis, “bird”) + δειρή (deirḗ, “throat”), defined as the last common ancestor of dinosaurs and pterosaurs, and all of its descendants ...
This list of pterosaurs is a comprehensive listing of all genera that have ever been included in the order Pterosauria, excluding purely vernacular terms.The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (nomen dubium), or were not formally published (nomen nudum), as well as junior synonyms of more established names, and genera that are ...
The pterosaur Boreopterus for example, was initially classified within the Ornithocheiridae; however, later analysis had found it in a different family called Boreopteridae, with Boreopterus being the sister taxon of Zhenyuanopterus; both pterosaurs were recovered as basal members of the Lanceodontia in several recent studies such as the ones ...
Anhangueridae is a group of pterosaurs within the suborder Pterodactyloidea. [2] They were among the last pterosaurs to possess teeth. A recent study discussing the group considered the Anhangueridae to be typified by a premaxillary crest and a lateral expansion in the distal rostrum.
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.
The two groups overlapped in time, but the earliest pterosaurs in the fossil record are basal pterosaurs, and the latest pterosaurs are pterodactyloids. [ 20 ] The position of the clade Anurognathidae ( Anurognathus , Jeholopterus , Vesperopterylus ) is debated. [ 21 ]
Azhdarchidae (from the Persian word azhdar, اژدر, a dragon-like creature in Persian mythology) is a family of pterosaurs known primarily from the Late Cretaceous Period, though an isolated vertebra apparently from an azhdarchid is known from the Early Cretaceous as well (late Berriasian age, about 140 million years ago).
