A group of researchers has discovered a fossilized reich of dinosaur "Anchiornis"Who had 4 wings and lived on Earth 160 million years ago.
The scientists said the discovery could illuminate the evolution of aviation, opening broad prospects for further study in this area.
Dinosaur "Anchiornis"It's the size of the gradient." Chemical analysis showed that the preserved feathers have the same proteins found in birds, although they are not suitable for long-range flying, but their molecular structure may indicate the intermediate stage of development of feathered birds.
