The French zoologist Georges Cuvier recognised that the Pterodactylus was a flying reptile, and that its elongated fourth fingers were attached to wings. He invented the word ‘Pterodactyl’. In its initial appearance on Isla Sorna, the Pteranodon was observed flying above various dinosaurs without displaying any signs of aggression or engaging in conflicts. One individual of the species was observed choosing to land on a tree branch, while the others continued to fly away from the area.

Pterodactylus lived around 150.8–148.5 million years ago, in the Late Jurassic epoch. (The Late Jurassic was the third epoch of the Jurassic Period.) Münster, Georg Graf zu (1830).

Paul, Gregory S. (2002). Dinosaurs of the Air: The Evolution and Loss of Flight in Dinosaurs and Birds. Johns Hopkins University Press. p.472. ISBN 0-8018-6763-0. Pterodactylus (from Greek pterodáktylos ( πτεροδάκτυλος) meaning 'winged finger' [2]) is an extinct genus of pterosaurs. It is thought to contain only a single species, Pterodactylus antiquus, which was the first pterosaur to be named and identified as a flying reptile and one of the first prehistoric reptiles to ever be discovered. Pterosaurs (including pterodactyls) are not birds. Neither are they early birds; birds actually evolved from dinosaurs, not from pterosaurs. Top Pterodactylus Facts For Kids The main facts to remember are that Pterodactylus was not a dinosaur, and that not all Pterosaurs are Pterodactyls! More Dinosaur Articles at Active Wild Body mass estimates for giant azhdarchids are extremely problematic because no existing species share a similar size or body plan, and in consequence, published results vary widely. [3] Generalized weight, based on some studies that have historically found extremely low weight estimates for Quetzalcoatlus, was as low as 70kg (150lb) for a 10m (32ft 10in) individual. A majority of estimates published since the 2000s have been substantially higher, around 200–250kg (440–550lb). [12] [13]

Introduction to dinosaurs

The smallest flying reptile was the size of a sparrow, the largest had a 60 foot, or 18-meter wingspan, and some walked on all fours. a b c d e f g h i j k l Bennett, S. Christopher (2013).

If you were anything like me, much of your childhood was spent being fascinated by anything and everything related to dinosaurs. From movies and books to junior fossil-cleaning kits, there is something about digging ancient bones out of the dirt that appeals to the human senses of wonder and awe. One of the most interesting prehistoric creatures did not prowl on the ground among the Tyrannosaurus Rex and Brontosaurus, but instead soared overhead, with wings spanning dozens of feet, in some cases. After escaping the Pteranodons displayed aggressive behavior towards humans when they reached Main Street. They would seize individuals, attempting to carry them through the air, but often dropped them if they were too heavy. For instance, there was an incident where a Pteranodon tried to lift a juvenile triceratops but was unable to due to the weight. One specific case involved Zira, who was initially captured by a Pteranodon but was dropped, only to be caught by another flying reptile. Unfortunately, both Zira and the other prey ended up being dropped into a lagoon, where they were subsequently consumed by the mosasaurus. As a result of this encounter, other Pteranodons seemed to avoid getting involved in the situation. When it was first named as a new species in 1975, scientists estimated that the largest Quetzalcoatlus fossils came from an individual with a wingspan as large as 15.9m (52ft). Choosing the middle of three extrapolations from the proportions of other pterosaurs gave an estimate of 11 m, 15.5 m, and 21 m, respectively (36ft, 50.85ft, 68.9ft). In 1981, further advanced studies lowered these estimates to 11–12m (36–39ft).

Pterosaurs and dinosaurs share a common ancestor, but the two should not be conflated, as their evolutionary history is clear. Another common mistake people make when discussing pterosaurs is referencing them as the ancestors of birds. Bennett, S. C. (2004). "New information on the pterosaur Scaphognathus crassirostris and the pterosaurian cervical series". Journal of Vertebrate Paleontology. 24 (Supplement 003): 38A. doi: 10.1080/02724634.2004.10010643. ISSN 0272-4634. S2CID 220415208. The word ‘pterodactyl’ is often used to refer to all Pterosaurs. However, it should only really be used to refer to Pterodactyloids, and more specifically to Pterodactylus. It’s best to say ‘pterodactylus’! Hoffstetter, R. (1966).
