Understanding What a Pterosaur Is
A pterosaur was a prehistoric flying reptile that lived during the age of dinosaurs. They were the first vertebrates capable of powered flight.
How Pterosaurs Looked
Pterosaurs had lightweight bodies, long wings made from skin membranes, and in many species, large crests on their heads. Their wings stretched from the body to an extended fourth finger.
What Pterosaurs Ate
Different species had different diets. Some ate fish, others hunted small animals or insects. Their beaks and teeth adapted to their feeding style.
Where Pterosaurs Lived
Fossils show they lived across the world, from coastal regions to inland environments. They shared Earth with dinosaurs but were not dinosaurs themselves.
How Big Pterosaurs Could Be
Sizes ranged from small species with wingspans under one meter to giants like Quetzalcoatlus, which had wingspans over 10 meters—similar to a small airplane.
Why Pterosaurs Are Important
Their fossils reveal how flight evolved in reptiles and provide a window into ancient ecosystems. They were among the most successful fliers in Earth’s history.
The Simple Takeaway
Pterosaurs were flying reptiles that soared over prehistoric landscapes. Their fossils show how diverse and impressive ancient life could be.
