Pterosaurs included the largest flying animals ever to have lived. They are a clade of prehistoric archosaurian reptiles closely related to dinosaurs. Species among pterosaurs occupied several types of environments, which ranged from aquatic to forested. Below are the lists that comprise the smallest and the largest pterosaurs known as of 2022.
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.
This would have made Arambourgiania the largest pterosaur ever known. [5] [4] In 1997, paleontologist Lorna Steel and colleagues reconstructed a life-sized skeleton of Arambourgiania based on better-known related pterosaurs. They set its wingspan at 11.5 m (38 ft), within the range of Frey and Martill's estimate.
The members of the Hațeg Island ecosystem lived on a landmass known as the Tisia–Dacia Block, of which the Hațeg Basin was a small part. This landmass was about 80,000 km 2 (31,000 sq mi) in area, and was separated from other terrestrial terrains by stretches of deep ocean in all directions by 200 to 300 km (120 to 190 mi). [ 24 ]
Daeodon and similar in size and morphology Paraentelodon [65] were the largest-known entelodonts that ever lived, at 3.7 m (12 ft) long and 1.77 m (5.8 ft) high at the shoulder. [66] The huge Andrewsarchus from the Eocene of Inner Mongolia had a skull about 83.4 cm (32.8 in) long [67] though the taxonomy of this genus is disputed. [68] [69]
The fossil was found in a limestone quarry in Bavaria during research led by Professor David Martill of the University of Portsmouth.
Pterosaurs had a wide range of sizes, though they were generally large. The smallest species had a wingspan no less than 25 centimetres (10 inches). [12] The most sizeable forms represent the largest known animals ever to fly, with wingspans of up to 10–11 metres (33–36 feet). [22] Standing, such giants could reach the height of a modern ...
Earth became a dark, noxious landscape of dead vegetation littered with charred carcasses of dinosaurs, pterosaurs and other creatures. By the time the Cretaceous-Paleogene, or K/Pg, extinction ...
