Quick: name all the types of animals that have feathers!
You probably said birds. Birds have feathers, which enable them to fly.
Many of you might think that birds are the only animals to have ever existed that have feathers.
Since the 1990s, Paleontologists have discovered species after species of extinct dinosaurs that were also covered in feathers. These were flightless theropods that may have used their feathery body coverings for insulation, protection from the elements and as displays for potential mates.
