The Discovery
A remarkably detailed fossil of a small, feathered dinosaur named Norellraptor barsboldi has been uncovered in north-eastern China. The specimen belongs to a group of small, winged dinosaurs known as microraptors. These animals are members of the Paraves family, a broader group of theropod dinosaurs that includes modern birds. Research led by paleontologist Xuri Wang from the Chinese Academy of Geological Sciences and his colleagues, published in Nature Communications, indicates that this newly described creature was likely capable of flight.
What Scientists Found
The fossilized remains of the dinosaur provide key insights into its physical traits and development:
- The body measures 57 centimeters (just over 22 inches) in length.
- Analysis of the bones shows that the individual had not yet completed its growth when it died.
- The forelimbs and tail featured flight-related plumage, while simple, straight feathers covered the rest of its body.
- Development of the animal's wing, or forearm, appears to have halted early in life, which is the reverse of what occurs in living flying birds.
Why It Matters
This discovery disrupts previous assumptions about how birds and their relatives took to the air. Instead of microraptors and birds inheriting the ability to fly from a single shared ancestor, the evidence points toward convergent evolution. This process occurs when separate groups reach a similar capability through entirely different evolutionary paths.
The steps and growth patterns that led to flight in microraptors differ consistently from those seen in birds, suggesting flight may have evolved independently at least twice within the Paraves group. However, researchers emphasize that more fossil evidence is necessary before the scientific community can definitively rewrite the evolutionary history of avian flight.
