7 Giant Animals That Are Now Extinct Part 1

2. Quetzalcoatlus

The Largest Flying Animal Ever

Quetzalcoatlus was not a dinosaur—it was a flying reptile (pterosaur).

Key facts:

• Wingspan: 33–40 feet
• Beak length: over 8 feet
• Lived with dinosaurs
• Mostly scavenged or hunted small animals

Despite its size, it could fly due to lightweight bones. It went extinct during the asteroid impact that wiped out dinosaurs 66 million years ago.
