Found by paleontologists a feathered dinosaur (changyuraptor yangi) during life, feathers were completely covered, including his hands and legs. It is the thick and long plumage that gives the impression that dinosaur two pairs of wings, hence the name of this species /esoreiter.ru/. The fossils of this dinosaur were discovered in 2012. in the province of Liaoning (northeast of China). Liaoning over the past decade has been considered a center of discovery feathered dinosaurs, the remains of which in most cases are found local farmers. Discovered four-winged dinosaur stomped the surface of our planet even before the appearance of birds (125 million years back). He had very long feathers and a fluffy tail, which, according to scientists may be evidence of ability four winged dinosaur flying. This miniraptor belongs to the group vertebrate feathered predators. Microscopic structure analysis bones confirmed that the remains belong to an adult. His length 1.2 meters and weight 4 kg suggest that this lizard is the most the largest of the four-winged dinosaurs ever found. Scientists suggest that this species is a close relative of birds. Perhaps they had a common ancient ancestor, who subsequently lost somewhere on the evolutionary ladder. Estimated area the habitat of the miniraptor is considered a fairly large peninsula, having a wedge-shaped protrusion, far reaching into the ocean. At that the climate of this peninsula was distinguished by hot summers and quite cold winter. It grew a humid temperate forest, consisting mainly from conifers and the earliest flowering plants. This area has also been a habitat of great diversity. insects, as well as some very primitive reptiles. Lakes on the peninsula was teeming with fish, frogs and salamanders. Until the end it is clear what kind of food they preferred to see on their menu four-winged dinosaurs, however, based on the remains of fossils, most likely they ate fish, salamanders and small reptiles. The tail feathers of the dinosaur found were unusually long (0.3 meter). Apart from birds, these are the longest tail feathers that scientists have ever seen. Still the longest tail feathers of a miniraptor recognized feathers of 0.18 m in length. Exactly long plumage prompted scientists to the version that these dinosaurs were able to fly. The aerodynamic calculations of scientists show that the long tail feathers helped the mini-raptor slow its decline, ensuring safety of landings, as well as smoothness and lightness soaring in the air.
