New evidence suggests that passive wing flapping may have arisen earlier than gliding flight

Birds produce varying coloration in their feathers by using nanoscale arrays of melanin-filled organelles layered with keratin

Just like human dandruff, dinosaur fossil dandruff is made of tough cells called corneocytes, which in life are dry and full of the protein keratin

Researchers from China, Canada, and the University of Bristol have discovered a dinosaur tail complete with its feathers trapped in a piece of amber

Scientists have successfully replicated the molecular processes that led from dinosaur snouts to the first bird beaks

The study applied new numerical methods that calculate the rate of evolution of different characteristics across a whole evolutionary tree.
