Fossil birds during 30 cm to be strong evidence that indeed there was a bird that explore Earth's sky in the days of the dinosaurs. Presence against the origin of bird species for this. Scientists believe that birds evolved from dinosaurs a Theropods, from the early Cretaceous period, about 120-130 million years ago. New findings in the area of Northeast China appears far older Theropod rather than living in the middle of the Jurassic age. Scholars estimate, Eosinopteryx on Earth more than 145 million years ago. "These findings shed further doubt on previous theories, that the famous fossil Archaeoptryx and touted as the first bird. And this finding is very important for the evolution of modern birds," said Dr Gareth Dyke, a senior lecturer of Vertebrate Palaeontology at the University of Southampton. "These findings thus indicate that the origin of the bird or birds are far more complex than previously estimated,"  Dyke. According to the analysis in fossils, ancient birds and feathered Eosinopteryx own body can not fly. Because their wings are too small width, and again a bone structure limits the ability to flap the wings.
