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.
However, in 2010, Brian Andres re-defined the group as a stem-based taxon in his dissertation, [10] and then formalized the definition in 2014 as all pterosaurs more closely related to Pteranodon longiceps than to Pterodactylus antiquus. [3] The slightly more exclusive group Ornithocheiroidea was re-defined in 2003 by Alexander Kellner.
Pterosaur pelts might have been comparable in density to many Mesozoic mammals. [d] [78] Specimens of anurognathid pterosaurs (Sinomacrops pictured) were the first to indicate complex feather-like structures in pterosaurs. Pterosaur filaments could share a common origin with feathers, as speculated in 2002 by Czerkas and Ji. [33]
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).
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.
