GoKawiilFossil of feathered dinosaur Norellraptor barsboldi suggests flight evolved multiple times
Researchers described a complete fossil of Norellraptor barsboldi, a microraptorine dinosaur showing feather traces on its limbs and tail. The team found that flight-related adaptations seen in this group also appeared independently in the bird lineage Avialae, but developed in a different sequence. The findings were published in Nature Communications.
