Size comparison of Q. northropi (green), Q. lawsoni. (blue), and a human. This is a list of pterosaurs with estimated maximum wingspan of more than 5 meters (16 feet):
Size of the sub-adult holotype (blue) and adult (green) specimens in both flying and standing postures, compared with a human. Pterodactylus is known from over 30 fossil specimens, and though most belong to juveniles, many preserve complete skeletons.
The relative size of the hands and feet in pterosaurs (by comparison with modern animals such as birds) may indicate the type of lifestyle pterosaurs led on the ground. Azhdarchid pterosaurs had relatively small feet compared to their body size and leg length, with foot length only about 25–30% the length of the lower leg.
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.
Size of Istiodactylus latidens compared to a human Ornithocheiromorphs were large pterosaurs, with wingspans normally ranging between 3 and 6 meters (9.8 and 19.7 ft). [ 3 ]
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 ...
A millimeter-sized sea animal could hold clues to the evolution of the human nervous system. While placozoans are simple animals only as big as a grain of sand, the blobs have unique cells that ...
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.
