Feathers appeared before the dinosaurs and birds and were not meant to fly
It has long been believed that dinosaurs, like lizards and other reptiles are covered with scales, but in fact they might have feathers. This was evidenced by the many fossils of ancient creatures, a new discovery of researchers from the University of Bristol at all proves that the feathers of some animals appeared much earlier than in birds and dinosaurs. The most interesting is that they were not meant to fly.
According to Professor Michael Benton from Bristol University, the feathers of animals appeared 80 million years before the appearance of the birds themselves. The oldest bird remains Archeopteryx, however, Chinese paleontologists for the last ten years have unearthed the remains of more ancient creatures that have almost the same plumage, as well as in modern birds.
The plumage appeared earlier than expected
According to the researchers, the feathers are formed by proteins beta-keratin, and the first signs of associated genetic changes were reported by scientists at the animal remains that lived about 250 million years ago, at the beginning of the Triassic period. At this time, ancient animals just mastered the different modes of transportation and improve the system of regulation of body temperature. That's why researchers believe that feathers not used for flight - is more likely that in 80 million years before the appearance of the birds feathers provide insulation. Insulating feathers could have found in Russia dinosaur kulindadromeus. His body was not just covered with feathers, and thanks to various forms of feather structures in different areas of the body, tail ensuring good thermal regulation. Dinosaurs looked, with their feathers can be seen in our material.
