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.

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 ...
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 ...
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]
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.
Arthurdactylus is a genus of pterodactyloid pterosaur from the Early Cretaceous Crato Formation of northeastern Brazil. It was a medium-sized pterosaur, with a wingspan of 4.5–4.6 metres (14.8–15.1 ft) and body mass of 15 kg (33 lb).
An updated and more resolved version of this phylogeny was published formally by Andres and Timothy Myers in 2013, containing 185 characters and 109 ingroup taxa. Below is a cladogram showing these results after the exclusion of three taxa that can be coded only for one character (clade names follow Andres & Myers, 2013).
