What You Will Learn From This Lesson
- Pterosaurs were flying reptiles, not dinosaurs.
- Pterosaur wings were skin supported by a long fourth finger.
- Pterosaurs were carnivores that scavenged and ate small animals.
Were Pterosaurs Actually Dinosaurs?
Pterosaurs are often mistaken for flying dinosaurs, but they were actually a distinct kind of flying reptile. They lived during the same time as the dinosaurs but belonged to a different scientific group. The largest Pterosaur discovered was the Quetzalcoatlus. This giant reptile had a massive wingspan that could reach about 40 feet, nearly the size of a small airplane. On the other end of the scale, the smallest Pterosaur was the Nemicolopterus, which had a wingspan of only about 10 inches and was roughly the size of a sparrow.
How Did Pterosaurs Fly?
Pterosaurs were natural flyers thanks to their unique body structure. Their wings were made of a membrane of skin, not feathers like modern birds. This wing membrane was supported by the Pterosaur’s arm and an elongated fourth finger. This unique structure allowed them to fly. The Quetzalcoatlus also had strong, well-developed pectoral muscles, enabling powerful flapping and soaring in the sky. Their body were slender and lightweight, featuring a streamlined shape that reduced air resistance for efficient flight.
What Did Pterosaurs Eat for Food?
Pterosaurs were carnivorous and had a varied diet. They used their bird-like beak to search for food on the ground while flying high in the sky. While preying on live animals used too much energy, they sought out animals that were already dead, essentially scavenging for dead dinosaurs. They also actively hunted a variety of smaller creatures. This included lizards, fish, and small dinosaurs. The tiny Nemicolopterus, being about the size of a sparrow, primarily ate insects.
Fun Fact
- The largest Pterosaur, the Quetzalcoatlus, had a wingspan of up to 40 feet, almost the size of a small airplane.
- The Pterosaur’s wing was a skin membrane supported by its arm and one extra-long fourth finger.
- Quetzalcoatlus had a slender, lightweight body and a streamlined shape to help it reduce air resistance while flying.
- The smallest Pterosaur, Nemicolopterus, was only 10 inches wide and was comparable in size to the size of a sparrow.
- Pterosaurs had strong chest muscles, which allowed them to soar and climb in the air freely.
