Feathered dinosaurs

Feathered dinosaurs are a group of dinosaurs that are believed to have had feathers, similar to modern birds. Evidence from fossils suggests that some species, especially theropods (the group that includes tyrannosaurs and velociraptors), had feathers to aid in insulation or display, rather than flight. This discovery has helped to bridge the evolutionary link between dinosaurs and birds, supporting the idea that birds are a modern lineage of theropod dinosaurs. The presence of feathers indicates a more complex appearance and behavior than previously thought, shedding light on their ecology and evolution during the Mesozoic era.
