Pterodactyl
Pterodactyl is an informal term most often used for pterosaurs, the extinct flying reptiles that lived alongside dinosaurs.
Pterodactyl is an informal term most often used for pterosaurs, the extinct flying reptiles that lived alongside dinosaurs. In strict scientific usage, it can also refer to the genus Pterodactylus, especially Pterodactylus antiquus, one of the first pterosaurs to be named and studied. These creatures were not dinosaurs but a separate group of reptiles that evolved powered flight.
Name and classification
The word pterodactyl is an informal term that people often use for all pterosaurs, but it is also associated with the genus Pterodactylus. Scientific sources distinguish these flying reptiles from dinosaurs and place them in the order Pterosauria.
Appearance and flight
Pterosaurs were flying reptiles with skin-based wings, hollow bones, and an elongated finger supporting the wing membrane. They were the first vertebrates known to evolve powered flight.
Fossil record and time period
Pterosaurs first appeared in the Triassic Period and lasted until the end of the Cretaceous Period, about 66 million years ago. Fossils have been found in many parts of the world.
Diet and ecology
Many pterosaurs were carnivores. Depending on habitat, they fed on fish near water or on small animals away from water.
Key facts
- Pterodactyl is commonly used as a general name for pterosaurs, but scientifically it is more precise to use Pterosauria or Pterodactylus depending on the context.
- Pterosaurs were not dinosaurs; they were a separate group of flying reptiles that evolved powered flight.
- The best-known specific animal associated with the name is Pterodactylus antiquus, the first pterosaur to be named and identified.
- Pterosaurs had membranous wings supported by an elongated finger, unlike the feathered wings of birds.
- Many pterosaurs were meat-eaters, with diets that often included fish or small animals.
Canadian museums and educational resources commonly use pterosaurs and pterodactyls to explain prehistoric life, flight evolution, and the difference between dinosaurs and other reptiles.[12][18]
