New feathered, winged dinosaur from China challenges our theories on bird and dinosaur evolution

A newly described feathered dinosaur found in northeastern China adds evidence supporting the theory that flight-related features evolved differently in various bird-like dinosaur groups. The findings, reported in Nature Communications, are based on an analysis of an exceptionally well-preserved fossil of a microraptorine (a small dinosaur with feathers and wings) found in a geological formation estimated to be between 145 and 100 million years old.
