Delve into the recent findings of early Cretaceous dinosaur fossils in China with feather-like structures, linking these creatures to birds. Explore controversies surrounding these discoveries and debate over whether some feathered dinosaurs are actually early birds. Discover the presence of feather-like structures in Longisquama, a Triassic basal archosaur, raising questions about the origins of feathers in dinosaurs. Are the feather-like structures on Microraptor and Longisquama truly primitive feathers?
