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).
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]
Some advanced pterosaurs such as Pteranodon had highly elongate wings. The pterosaur wrist consists of two inner (proximal, at the side of the long bones of the arm) and four outer (distal, at the side of the hand) carpals (wrist bones), excluding the pteroid bone, which may itself be a modified distal carpal.
Partly, this is due to the presence of air sacs in their wing membranes, [22] and that pterosaurs launched into flight using their front limbs in a quadrupedal stance similar to that of modern bats, a method faster and less energy taxing than the bipedal launching of modern birds.
This paper included the first illustrations of Pteranodon wing bones. [52] A pterosaur fossil bearing an impression of the wing membrane was discovered. This was the first physical evidence of the structure which had previously been inferred purely from skeletal anatomy. [21] Owen described the new genus Coloborhynchus. [53] 1875
Pteranodon sternbergi is an extinct species of the pteranodontid pterodactyloid pterosaur genus Pteranodon from the Late Cretaceous geological period of North America. P. sternbergi was among the largest pterosaurs, with a wingspan of up to 6 metres (20 ft) in males.
Quetzalcoatlus (/ k ɛ t s əl k oʊ ˈ æ t l ə s /) is a genus of azhdarchid pterosaur that lived during the Maastrichtian age of the Late Cretaceous in North America. The type specimen, recovered in 1971 from the Javelina Formation of Texas, United States, consists of several wing fragments and was described as Quetzalcoatlus northropi in 1975 by Douglas Lawson.
Meaning: wing, of a wing, respectively. Used for many winged creatures, but also expanded to mean "fin", and used for many undersea arthropods. The suffix "-ptera" is also used in orders of winged insects.
