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.
It was redesignated the 141st Operations Group and reactivated when the 141st Wing reorganized under the Objective Wing reorganization. The group's 116th Air Refueling Squadron was first organized during World War I as the 116th Aero Squadron, and is one of the 29 squadrons of the United States Army National Guard formed before World War II .
Pterosaurs are also colloquially referred to as pterodactyls, particularly in fiction and journalism. [16] However, technically, pterodactyl may refer to members of the genus Pterodactylus , and more broadly to members of the suborder Pterodactyloidea of the pterosaurs.
Pteranodon (/ t ə ˈ r æ n ə d ɒ n /; from Ancient Greek: πτερόν, romanized: pteron ' wing ' and ἀνόδων, anodon ' toothless ') [2] [better source needed] is a genus of pterosaur that included some of the largest known flying reptiles, with P. longiceps having a wingspan of over 6 m (20 ft).
Rhamphorhynchus (/ ˌ r æ m f ə ˈ r ɪ ŋ k ə s /, [1] from Ancient Greek rhamphos meaning "beak" and rhynchus meaning "snout") is a genus of long-tailed pterosaurs in the Jurassic period. . Less specialized than contemporary, short-tailed pterodactyloid pterosaurs such as Pterodactylus, it had a long tail, stiffened with ligaments, which ended in a characteristic soft-tissue tail va
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.
Pteranodontoidea (or pteranodontoids, from Greek meaning "toothless wings") is an extinct clade of ornithocheiroid pterosaurs from the Early to Late Cretaceous (early Valanginian to late Maastrichtian stages) of Asia, Africa, Europe, North America and South America. [1] It was named by Alexander Wilhelm Armin Kellner in 1996.
Wing structure and colouration often vary with morphs, such as in the aphids, migratory phases of locusts and polymorphic butterflies. At rest, the wings may be held flat, or folded a number of times along specific patterns; most typically, it is the hindwings which are folded, but in a few groups such as the vespid wasps, it is the forewings.
