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 discovery of Volaticotherium provided the earliest-known record of a gliding mammal (70 million years older than the next oldest example), [2] until the discovery of the contemporary haramiyidans Maiopatagium, Vilevolodon and Xianshou, and provided further evidence of mammalian diversity during the Mesozoic Era.
The largest living procyonid is the raccoon (Procyon lotor) of North America, having a body length of 40 to 70 cm (16 to 28 in) and a body weight of 3.5 to 9 kg (8 to 20 lb). The extinct Chapalmalania of South America was the largest known member of this family, about 1.5 metres (4.9 ft) in body length.
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.
A Mesozoic reptile is believed to have been the largest flying animal that ever existed: the pterosaur Quetzalcoatlus northropi, from North America during the late Cretaceous. This species is believed to have weighed up to 126 kg (278 lb), measured 7.9 m (26 ft) in total length (including a neck length of over 3 m (9.8 ft)) and measured up to ...
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]
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).
The northern greater glider has a brownish-gray coloration, the central greater glider has a dark silvery-brown coloration with dark brown face, legs, and tail, while the southern greater glider varies between a dark, almost black morph or a pale white and gray morph. Body mass varies from 1,600 grams (3.5 lb) in the southern greater glider of ...
