Some recent studies argue that they were closer to birds than reptiles. Now they discovered that the microrraptores probably had feathers of colors, for the attention of females.
Even a dinosaur can look elegant when dressed in shiny black : a type of dinosaur, more like a bird than a reptile, had feathers of that color which probably served to draw attention when he wanted to mate , according to an article in the magazine Science.
It's like dressing for a night out in New York, but 130 million years ago and China, said Mark Norell of the American Museum of Natural Sciences, one of the authors.
It is the oldest example of an animal that looks iridescent, said co-author Julia Clarke. In other animals, especially birds, that glow in males is what attracts females.
The scientists concluded that it was brilliant the way the bags pigment found in a fossil in China.
Nothing in these animals, called microrraptores made them barely reached the 76 inches, evokes the frightening aspect of the dinosaurs of horror films: look black birds , except that they have teeth, claws and a strange set of wings secondary attachment to the legs. Also have decorative feathers long extending from the queue. Some paleontologists think they are birds.
"For me, a bird is an animal with hand and wrist with primary flight feathers," said Larry Martin, professor at the University of Kansas who was not involved in the study. "Under that definition, Microraptor is a bird."
None of this, the authors of the study. According to its skeleton and muscles, Microraptor could not fly , said Norell. At best he could glide from trees . Its skeleton what ties these more with the raptor that modern birds , he said. "Crows do not have teeth (or) clawed hands. Hands are identical to wild animals like velociraptor."
