LONDON. - The discovery of fossils of a four-wings dinosaur, unknown until the moment, throws more indications than the birds descend of those prehistoric animals, according to a published scientific study.
It could be the lost link between the dinosaurs and the birds, one of the keys more yearned by the specialists of the evolution.
That dinosaur lived in the trees and he learned how to slip taking advantage of the graveness force, before the birds flew shaking the wings", it points out the investigation, disclosed in the British scientific magazine \' Nature\'.
The fossils belong to a subspecies of a meter lenght of the dinosaur " microraptor " that these investigators consider as a near relative of the birds.
That dinosaur lived in China 130 million years ago, according to the team of experts of the Institute of Vertebrate Paleontology of Beijing that has carried out the investigation.
The six found fossils offer evidences about the characteristics of these missing animals that possessed wings covered with feathers and completely developed in their back and front extremities.
Their body should be covered for feathers of about 25 or 30 millimeters of longitude, while the feathers of the wings should be very similar to those that present the current birds.
The study suggests that the feathers of the front extremities and the paws would be what allowed to the dinosaur to slip among the trees in a similar way to bats.
The conclusion extracted by these Chinese experts is that there was an intermediate stage among the dinosaurs that populated the earth and didn\'t have capacity to fly, and the first animals that learned how to fly.
The dinosaurs appeared in the Earth 200 million years ago, in the first Jurassic, and they were perpetuated and they evolved with success until the Cretacic, disappearing 65 million years ago, at least the biggest species.
