Four-winged bird is missing dinosaur link: report
• NewscomAUAbout the size of a chicken, the fossil has a total body length of less than 50cm and a skull about 6cm long, lead researcher Xing Xu at the Chinese Academy of Science in Beijing said.
"This finding suggests that birds are likely to be descended from a kind of small-sized four-winged dinosaur about 160 million years ago," Mr Xu said.
"It is a link between more typical theropods (dinosaurs which moved around with two rear limbs) and birds. It lived around a time period ... that we expected for birds' ancestor."
The researchers said long feathers covered the creature's arms, tail and feet, suggesting that a four-winged stage "may have existed in the transition to birds".
