Quetzalcoatlus
Quetzalcoatlus was one of the largest flying animals that ever lived. It was a pterosaur, a flying reptile that lived at the same time as dinosaurs. With a wingspan as wide as a small airplane, it could soar over the ancient landscapes of Texas.21

Fun facts
Quetzalcoatlus had a wingspan of about 11 to 12 metres (36 to 39 feet), which is as wide as a small plane.2
It weighed only about 230 kilograms (500 pounds), which is light for its huge size, thanks to hollow bones.2
Quetzalcoatlus could walk on all fours using its wings as front legs, like a bat.2
It lived about 68 to 66 million years ago, right at the end of the age of dinosaurs.1
The first fossil was a single wing bone found by a student named Douglas Lawson in 1971.2
Quetzalcoatlus probably launched into flight by pushing off the ground with its strong front legs, not by jumping with its back legs.1
Myth buster
Myth: Many people think Quetzalcoatlus was a dinosaur.
Truth: Quetzalcoatlus was a pterosaur, a flying reptile that is not a dinosaur. Dinosaurs are a different group of animals.1
