“Pterodactyl” is the common term for the winged prehistoric creatures properly called pterosaurs, especially in the film industry. They swoop down menacingly and carry away the screaming heroines, while, in truth, most were not large enough to carry away something as large as a human.
Most of them.:) More on that later.
Pterosaurs lived among the dinosaurs and became extinct around the same time, but they were not dinosaurs.; actually, pterosaurs were flying reptiles.
Pteranodon and Pterodactylus weren’t all that closely related–but they were each interesting enough in their own right to merit the use of their proper names. There are many species of Pterodactyus and Pteranodon, and one of the most distinguishing characteristics of pterosaurs was the crest on their heads. Though no one is quite certain of their function,crests were widespread across pterosaur genera and came in various forms, with almost as much variation as in our birds of today. Also, modern birds are not descended from pterosaurs like Pterodactylus and Pteranodon, but from the small, two-legged predatory dinosaurs of the Jurassic and Cretaceous periods.
A major difference between the two: Pterodactylus had teeth; Pteranodon did not.
