Were There Any Flying Dinosaurs? The 12 Most Common Flying Reptiles

The term “flying dinosaurs” often brings to mind the image of a Pterodactyl soaring through the prehistoric sky. But were there really any flying dinosaurs? In truth, what we commonly refer to as “flying dinosaurs” are technically not dinosaurs at all but are a distinct group of prehistoric flying reptiles known as pterosaurs. Let’s delve into the world of these fascinating creatures.

Understanding Pterosaurs: The ‘Flying Dinosaurs’

Pterosaurs, often mistaken for dinosaurs, were the first vertebrates known to have evolved powered flight. They lived alongside dinosaurs for millions of years, filling the skies while their dinosaur relatives roamed the land.

Contrary to popular belief, the famous Pterodactyl is just one type of many pterosaurs. The term “Pterodactyl” specifically refers to members of the genus Pterodactylus, small to medium-sized pterosaurs that lived during the late Jurassic Period.

The Diversity of Pterosaurs

Pterosaurs came in an impressive array of shapes and sizes. Some were as small as modern birds, while others, like the Quetzalcoatlus, were the size of a small airplane, making it the biggest flying dino. Here are some notable types of flying dinosaurs:


The Pteranodon is one of the most well-known pterosaurs. With its distinctive crest and large wingspan, this flying dinosaur was an impressive sight. Despite its fearsome appearance, Pteranodon was likely a piscivore, diving to catch fish and squid.


The Rhamphorhynchus was a smaller pterosaur with a long tail tipped with a diamond-shaped vane. This dinosaur bird name is derived from its beak shape, which means “beak snout” in Greek.


Named after the Aztec feathered serpent god, Quetzalcoatlus was one of the largest known flying animals of all time. With a wingspan up to 10 meters, it’s no wonder this creature is often mistaken for a dinosaur bird.

Pterosaurs vs Dinosaurs: What’s the Difference?

While pterosaurs and dinosaurs lived during the same era and are both reptiles, they belong to different scientific classifications. Dinosaurs are part of the ‘Dinosauria’ clade, while pterosaurs belong to the ‘Pterosauria’ group.

One key difference between these two groups is their anatomy. Pterosaurs were adapted for flight, with hollow bones, large brains for coordinating flight, and an elongated fourth finger to support their wing membrane. In contrast, dinosaurs were primarily terrestrial creatures.

Could Dinosaurs Fly?

While no true dinosaurs could fly, some evolved feathers and bird-like characteristics. These ‘bird dinosaurs,’ such as Archaeopteryx and Velociraptor, are considered the ancestors of modern birds. However, they did not possess the adaptations for powered flight seen in pterosaurs.

Flying Reptiles Today

Are there any flying reptiles today? The answer is no. The pterosaurs, along with the dinosaurs, went extinct at the end of the Cretaceous period around 66 million years ago. However, their legacy lives on in the birds we see today.


The world of prehistoric flying reptiles is fascinating and diverse. From the small Pterodactyl to the gigantic Quetzalcoatlus, these creatures dominated the skies of the Mesozoic era. While they may not technically be “flying dinosaurs,” pterosaurs are a testament to the incredible diversity and adaptability of life on Earth.
