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.
For comparison, the wandering albatross has the largest wingspan of living birds at up to 3.5 m (11 ft) but usually weighs less than 12 kilograms (26 lb). This indicates that the largest pterosaurs may have had higher wing loadings than modern birds (depending on wing profile ) and this has implications for the manner in which pterosaur flight ...
Compared to the other vertebrate flying groups, the birds and bats, pterosaur skulls were typically quite large. [24] Most pterosaur skulls had elongated jaws. [24] Their skull bones tend to be fused in adult individuals. [24] Early pterosaurs often had heterodont teeth, varying in build, and some still had teeth in the palate.
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 ...
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 amount of "meat" is equivalent to that of all 7 billion humans on the planet combined. Spiders could, theoretically, eat every single human on earth within one year. It gets worse.
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.
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).
