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.
The class Mammalia is divided into two subclasses based on reproductive techniques: egg-laying mammals (yinotherians or monotremes - see also Australosphenida), and mammals which give live birth . The latter subclass is divided into two infraclasses: pouched mammals ( metatherians or marsupials ), and placental mammals ( eutherians , for which ...
Pterodactyloidea (derived from the Greek words πτερόν (pterón, for usual ptéryx) "wing", and δάκτυλος (dáktylos) "finger") [2] is one of the two traditional suborders of pterosaurs ("wing lizards"), and contains the most derived members of this group of flying reptiles.
The egg from the Lagarcito Formation was laid by a Pterodaustro, [197] [198] a pterosaur known by abundant material. [199] This was supported by the description of an additional pterosaur egg belonging to the genus Darwinopterus , described in 2011, which also had a leathery shell and, also like modern reptiles but unlike birds, was fairly ...
In this analysis, they placed the species G. cristatus as the sister taxon of "G. rhamphastinus" within the family Germanodactylidae, and contrary to the concepts mentioned above, both of these species were recovered as closer relatives of more primitive pterosaurs, such as Pterodactylus, within the group Archaeopterodactyloidea.
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.
Petrodactyle (meaning "stone finger") is an extinct genus of ctenochasmatid pterosaur from the Late Jurassic Mörnsheim Formation (Solnhofen limestone) of Bavaria, Germany.The genus contains a single species, P. wellnhoferi, known from a partial skeleton belonging to a subadult individual.
