The anatomy of pterosaurs was highly modified from their reptilian ancestors by the adaptation to flight. Pterosaur bones were hollow and air-filled, like those of birds. This provided a higher muscle attachment surface for a given skeletal weight. The bone walls were often paper-thin.
Bennettazhia is a genus of tapejaromorph pterosaur which lived during the Albian stage of the Early Cretaceous from what is now the Hudspeth Formation of the state of Oregon in the United States. Although originally identified as a species of the pteranodontoid pterosaur Pteranodon , Bennettazhia is now thought to have been a different animal.
One of these was a slab showing a pterosaur. The precise time and location of this discovery are unknown. It was first reported in the scientific literature in 1971, by Léonard Ginsburg and Guy Mennessier. [14] In 1974, French paleontologist Jacques Fabre based on this specimen, MNHN CNJ-71, named a new species Gallodactylus canjuersensis. [15]

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).

Ornithodesmus (meaning "bird link") is a genus of small, dromaeosaurid dinosaur from the Isle of Wight in England, dating to about 125 million years ago.The name was originally assigned to a bird-like sacrum (a series of vertebrae fused to the hip bones), initially believed to come from a bird [1] and subsequently identified as a pterosaur.
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.
Tapejaridae (from a Tupi word meaning "the lord of the ways") is a family of azhdarchoid pterosaurs from the Cretaceous period.Members are currently known from Brazil, England, Hungary, Morocco, [1] Spain, [2] the United States, [3] and China.
