Pterodactyloidea (/ˌtɛrəˈdækt͡ɬɔɪdɪːə/; derived from the Greek words πτερόν (pterón, for usual ptéryx) "wing", and δάκτυλος (dáktylos) "finger") [1] is one of the two traditional suborders of pterosaurs ("wing lizards"), and contains the most derived members of this group of flying reptiles.

Azhdarchoidea (/æʒdɑːrˈkɔɪdɪːə/, meaning "azhdarchid-like forms") is a group of pterosaurs within the suborder Pterodactyloidea. Pterosaurs belonging to this group lived throughout the Early and Late Cretaceous periods, with one tentative member, Tendaguripterus, that lived in the Late Jurassic period. Remains of this group have been ...
They indicated a single distinguishing trait. It is an autapomorphy, a unique derived character. The symphysis of the lower jaws has at the midline of its front an odontoid, or tooth-like, process, formed by a confluence of the side ridges of the occlusal groove, in the top surface of the joint dentaries.

Eupterodactyloidea was named by S. Christopher Bennett in 1994 as an infraorder of the suborder Pterodactyloidea. Bennett defined it as an apomorphy-based clade. [2] However, in 2010, Brian Andres re-defined the group as a stem-based taxon in his dissertation, [3] and then formalized the definition in 2014 as all pterosaurs more closely related to Pteranodon longiceps than to Pterodactylus ...
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.
Archaeopterodactyloidea (meaning "ancient Pterodactyloidea") is an extinct clade of pterodactyloid pterosaurs that lived from the middle Late Jurassic to the latest Early Cretaceous periods (Kimmeridgian to Albian stages) of Africa, Asia, Europe and North America. [2]
Anhanguera (Portuguese: [ɐɲɐ̃ˈɡwɛɾɐ] ⓘ) is a genus of pterodactyloid pterosaur known from the Early Cretaceous (Albian age, 125 to 112 million years ago) Romualdo Formation of Brazil (precisely in Araripe Basin) and the Late Cretaceous (Cenomanian age, 98 to 93 million years ago) Kem Kem Group of Morocco.
