feathered dinosaur fossils

Feathered dinosaur fossils are preserved remains of dinosaurs that show evidence of having had feathers, similar to modern birds. These fossils, often well-preserved in fine-grained rocks, reveal structures like downy filaments or quill-like feathers, indicating that feathers existed on non-avian dinosaurs. Discoveries have deepened our understanding of how some dinosaurs evolved into birds, emphasizing their close evolutionary relationship. The fossils demonstrate that feathers likely served purposes beyond flight, such as insulation, display, or communication, providing insight into the diversity and complexity of dinosaur biology.
