Ancient Feather Discoveries Uncover Startling Connections Between Dinosaurs and Birds

A new study using powerful X-rays has revealed that dinosaur feathers had a protein composition similar to modern birds, suggesting an early origin of bird feather chemistry, possibly 125 million years ago. The research found that the alpha-proteins in fossil feathers likely formed due to heat during fossilization, rather than being originally present. This discovery provides insights into the evolution of feathers and highlights the close relationship between dinosaurs and birds.

Uncovering Ancient Proteins through Dinosaur Feathers

Paleontologists at University College Cork have discovered X-ray evidence of proteins in fossil feathers, revealing that the protein composition of modern-day feathers was also present in the feathers of dinosaurs and early birds. The research confirms that the chemistry of feathers originated much earlier than previously thought and helps answer questions about the preservation of ancient biomolecules. The study provides new insights into feather evolution and the fossilization process.
