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.
Size of P. sternbergi male (green) and female (orange) compared with a human. Pteranodon sternbergi was among the largest pterosaurs, with the wingspan of most adults ranging between 3 and 6 meters (9.8 and 19.7 ft). No complete skulls of adult males have been found, but a nearly complete lower jaw has been estimated at 1.25 meters (4.1 ft ...
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.
A later study suggested that while smaller-bodied pterosaurs were most likely superprecocial or precocial, owing to the consistent or decreasing wing aspect ratio during growth, certain large-bodied pterosaurs, such as Pteranodon showed possible evidence of their young being altricial, due to the fast rate the limb bones closest to the body ...
The fossil shows the huge flying reptile would have had an estimated wingspan of more than 2.5 metres.
Scale diagram comparing a human and the longest-known dinosaurs of five major clades An adult male bee hummingbird, the smallest known and the smallest living dinosaur. Size is an important aspect of dinosaur paleontology, of interest to both the general public and professional scientists.
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.
Approximate size of I. latidens compared to a human. Istiodactylus was quite a large pterosaur, with estimates of its wingspan ranging from 4.3 to 5 metres (14 to 16 ft). This makes it the largest known member of its family, Istiodactylidae. Some isolated pterosaur wing-bone fragments that may belong to this genus indicate a wingspan as large ...
