A Pteranodon is a flying reptile found within Isla Sorna.
The Pteranodons in Jurassic Park III are depicted correctly with regards to their size (paleontologists claim that the largest species had a wingspan up to 10 m (33ft) wide, being the size of a small aircraft), as well as their quadrupedal gait. They are, however, shown incorrectly to have teeth, stemming from unknown mutation. In The Lost World they are portrayed as toothless. Paleontologists believe that Pteranodons could not lift prey with their feet, simply because their feet were not designed to grasp; instead, they caught most of their prey with their large beaks. They also lack the fur-like pycnofiberous integument that all true pterosaurs had. The number of eggs or young that Pteranodons could have in one single brood is unknown; however, the movie correctly portrays pterosaurs as being able to fly from a very early age, like real pterosaurs. All Pteranodons in Jurassic Park III are shown to have long crests of about the same size, when in real life, only Pteranodon males would have had large crests, with females having smaller ones. Jurassic Park Pteranodon suffer from the same level of accuracy that plagues most pop cultural depictions of pterosaurs: it is basically "stuck in the 70's", being depicted as a naked, leathery creature instead of the warm-blooded, almost bird-like animals that real pterosaurs were.
In the second movie, they are depicted as bipedal and with bird-like necks, while real pterosaurs were quadrupedal and had rigid, thick necks like those of mammals. The third movie fixes these errors, though it depicts them with grasping, bird-like feet and teeth. In Jurassic Park III, they do not appear but are replaced by mutant untrue Pteranodon quarantined in the Isla Sorna Aviary. Director Joe Johnston had the species re-designed for this film. They were shown as being larger, more robust and different colored than the ones shown at the end of The Lost World. They also lack a hooked bill, but have rows of dinosaur-like teeth on their mouths (something real-life Pteranodons never have).
- The unnamed animal comes from Africa and is not a bird but sounds bird-like
- The sounds of the baby Pteranodons are actually mongooses fighting
- They were originally gonna attack the helicopter in The Lost World: Jurassic Park, but was scrapped; that would later be used for Jurassic World.
