As per a new research carried out by American and Chinese scientists, it has been revealed that four-winged dinosaurs used to live some 130 million years ago in rural China. They were quite different from the usual giant dinosaur and were more like a crow.
They also had glittering wings, which researchers said that they used it for attracting females for mating. In addition to the glossy feathers, it has also been found that this unusual species of dinosaur also had long and narrow tail feathers, which is also said to be used at the time of attracting females.
Matthew D. Shawkey, who is a biologist at the University of Akron in Ohio, was of the view that they have assessed the pigment-containing cells of the unique dinosaur and then compared it with modern birds.
It was found that the placement of cells was exactly the same as it is in the case of modern birds having glossy feathers. “Our evidence that Microraptor was largely iridescent thus suggests that feathers were important for display even relatively early in their evolution”, said Shawkey.
He further affirmed that the feathers are of great importance for birds. They use it for different purposes like for flying, regulation of body temperature and for mate-attracting displays. It fact, it has been recently revealed that feathers are also used for visual social signals.
Previous researches conducted on the same subject had revealed that many birds in the past used their feathers and tails to attract females for mating. The most appropriate example to explain the situation will be of peacock. Male peacock also spreads its colorful feathers to attract females. Same was the case with the unique dinosaurs, said Shawkey.
