This is the largest species of Petauroides and one of the world's largest gliding mammals, growing to the size of a house cat. [8] Its body spans 35–46 cm (14–18 in). Its furry tail reaches up to 60 cm (24 in) long, [4] but is not prehensile. The gliding membrane stretches from the forearm to the tibia. [10]
A gliding eutriconodont, long considered the earliest gliding mammal until the discovery of contemporary gliding haramiyidans. It lived around 164 million years ago and used a fur-covered skin membrane to glide through the air; [ 78 ] it lived around 165 million years ago, during the Middle-Late Jurassic of what is now China.
The gliding posture of the greater gliders is unique among marsupials. The forelimbs are folded so that the wrists are tucked under the chin, giving the patagium a triangular outline when outstretched. These animals regularly glide between high trees, and are able to use their tails to assist in steering.
This gliding membrane, or patagium, runs from the shoulder blades to the fore paws, from the tip of the rear-most fingers to the tip of the toes, and from the hind legs to the tip of the tail. [9] The spaces between the colugo's fingers and toes are webbed.
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 first 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 Andean condor is the largest living land bird capable of flight if measured in terms of average weight and wingspan, although male bustards of the largest species (far more sexually dimorphic in size) can weigh more. [14] [19] [20] The mean wingspan is around 283 cm (9 ft 3 in) and the wings have the largest surface area of any extant bird ...

This is a list of the fastest flying birds in the world. A bird's velocity is necessarily variable; a hunting bird will reach much greater speeds while diving to catch prey than when flying horizontally. The bird that can achieve the greatest airspeed is the peregrine falcon (Falco peregrinus), able to exceed 320 km/h (200 mph) in its dives.
