What to know about 'Feathered dragon' has some of the longest tail feathers ever found on a fossil bird

Researchers have identified a new species of fossil bird from the Cretaceous Period named Plumadraco bankoorum, characterized by exceptionally long tail feathers. The study suggests these feathers were likely used by males for courtship displays to attract mates, indicating that such evolutionary traits existed over 120 million years ago.
