Male and female Pteranodon differed in size and crest shape. Males attained wingspans of 5.6–7.6 m (18–25 ft); females were smaller, averaging 3.8 m (12 ft). The crests of males were far larger than those of females. In P. longiceps, they were long and backswept, whereas in P. sternbergi, they were tall and upright.
Anurognathus is another small pterosaur, with a wingspan of 35 cm (14 in) and 40 g (1.4 oz) in body mass, [2] along with an indeterminate non-pterodactyloid pterosaur from the Portland Formation, although it is indeterminate and known from very fragmentary remains, only including a tooth, and part of the wrist bones.
On the ground, they would have had an awkward sprawling posture, but the anatomy of their joints and strong claws would have made them effective climbers, and some may have even lived in trees. Basal pterosaurs were insectivores or predators of small vertebrates. Later pterosaurs (pterodactyloids) evolved many sizes, shapes, and lifestyles ...
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.
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.
The fossil shows the huge flying reptile would have had an estimated wingspan of more than 2.5 metres.
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
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.
