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.
Their wings were formed by a membrane of skin, muscle, and other tissues stretching from the ankles to a dramatically lengthened fourth finger. [9] There were two major types of pterosaurs. Basal pterosaurs (also called 'non-pterodactyloid pterosaurs' or 'rhamphorhynchoids') were smaller animals with fully toothed jaws and, typically, long ...
Researchers say origin of flight may not be simple binary of ‘can or cannot’ but a spectrum of aerial movements
Dinosaurs were the largest terrestrial animals for much of the Mesozoic Era, and one group of small feathered dinosaurs (Aves, i.e. birds) has survived up to the present day. Pterosaurs were the first flying vertebrates and persisted through the Mesozoic before dying out at the Cretaceous-Paleogene (K-Pg) extinction event .
Pterodactylus (from Ancient Greek: πτεροδάκτυλος, romanized: pterodáktylos ' winged finger ' [2]) is a genus of extinct pterosaurs.It is thought to contain only a single species, Pterodactylus antiquus, which was the first pterosaur to be named and identified as a flying reptile and one of the first prehistoric reptiles to ever be discovered.
On the other hand, albatrosses have measured lift–drag ratios of 20, [29] and thus fall just 1 meter for every 20 in still air. Most maneuverable glider. Many gliding animals have some ability to turn, but which is the most maneuverable is difficult to assess.
Named Gondwanax paraisensis, the four-legged reptile species was roughly the size of a small dog with a long tail, or about 1 meter (39 inches) long and weighing between 3 and 6 kg (7 to 13 pounds ...
Maniraptora is a clade of coelurosaurian dinosaurs which includes the birds and the non-avian dinosaurs that were more closely related to them than to Ornithomimus velox. It contains the major subgroups Avialae, Dromaeosauridae, Troodontidae, Oviraptorosauria, and Therizinosauria. Ornitholestes and the Alvarezsauroidea are also often included.
