The Confuciusornis sanctus, which is 125 to 120 million years ago (#Mesozoic time period), from the Liaoning Province China was photographed for the @ナショナルジオグラフィック on the "Curious History of Feathers". The #evolutionary transition of such early birds may have played an important role in the evolution of flight. Confuciusornis and other early birds retained primitive claws on their wings that may have been used for climbing or predation; narrow feathers and weak flight muscles suggest it was not a powerful flier. #evolution
