Archaeopterodactyloidea

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] It was named by Alexander Wilhelm Armin Kellner in 1996 as the group that contains Germanodactylus, Pterodactylus, the Ctenochasmatidae and the Gallodactylidae. In 2003, Kellner defined the clade as a node-based taxon consisting of the last common ancestor of Pterodactylus, Ctenochasma and Gallodactylus and all its descendants. Although phylogenetic analyses that based on David Unwin's 2003 analysis do not recover monophyletic Archaeopterodactyloidea, phylogenetic analyses that based on Kellner's analyses, or the analyses of Brian Andres (2008, 2010, 2018) recover monophyletic Archaeopterodactyloidea at the base of the Pterodactyloidea.[3]

Classification

Below is a cladogram showing the results of a phylogenetic analysis presented by Longrich, Martill, and Andres, 2018.[4]

gollark: Yes, retroactively.
gollark: They're my alts. Just use that knowledge.
gollark: What? How does more caching mean less instruction decoding unless you're caching micro-ops?
gollark: Sad.
gollark: Don't ARM's fixed width instructions allow somewhat better decoders?
