TRYSK CRIGHT CRIGHT CRIGHT CRIGHT CRIGHT CRIGHT CRIGHT CRIGHT CRIGHT

Body cover, such as hair and feathers, have played a central role in evolution. He enabled the body to insulate the body, and was used to prevent companionship, display, enemies and, in the case of wings, in case of flight.

Their structure features are long and more complex skin, which are significantly different from the simple and flat scales of the crawling animals.

Earlier, the complex increase of the skin has been seen only in the shape of the hair and only in the birds and their closest fantasy relatives, dinosaurs and paterosurs only in the breasts.

An international team, led by Dr. Stephen Spackman and Professor Dr. Rainer Shuch, experts from the German State Museum of Natural History Stuttgart, described the residence of the unidentified trees before the early middle trusk in a journal published in the journal. Nature.

The 247 -year -old ancient crawling “Mirsura Grougli”, whose name means “Gargol’s Wonder Ringer,” had a durasel crust that had previously had an unknown, structurally complex supplement, which resembles the skin with some wings. Perhaps other members of this species were used for display.

The search shows that the complex skin structures are found not only in the birds and their close relatives, but can predict modern crawling animals. This important discovery forces us to revise our understanding of the evolution of the crawling animals.

The unique structures of the skin in the early crawling animals

Instead, the small Mirsura consists of a dense, dense overlaping supplement, in which each one has a feathers with a narrow central letter. Although the real wings contain many fragile branches called Barb, there is no evidence of such branches in Mirsura’s supplement. Because of this, the team believes that Mirsura’s complex, unique skin structure structure is widely developed by the birds.

“The fact is that we have discovered such a complex attachment in an ancient group of such complex skin affiliates that sheds a new light on their evolution. Mirsura is even older than dinosaur and is not closely associated with them,” the state of the state museum in Stuttgart and the natural history of the state museum.

“Development biology studies show that the genetic base for complex skin supplementation, such as wings, was probably 300 million years ago in the carbonifer period. Mirsura provides the first direct evidence that such structures were in fact developed in the evolutionary evolution.

The origin of the dinosaur and the wings

The study is a turning point in about 30 -year trends of palionological research, which began in the late 1990s with the discovery of feather dinosaurs in China. Prior to that time, it was thought that creeping animals, including dinosaurs giving birth to birds, were covered with scales and only true birds were wings.

As a result, dinosaurs were often shown as slow, open animals. This image changed when research began to show that many dinosaurs were more like birds than before.

In China, the discovery of wings, non -avian dinosaurs caused a wave of new studies that began to blur the lines between the rough, “on the one hand, the cold -blooded animals and the birds on the other, the” hot blood “birds faded. Now, it is clear that the story is even more complicated.

“Mirsura Gorogly shows us how wonderful evolution can be and how much it can have. It produces similar structures that are completely free from each other, but also the structure that is different from that.

The birds like the skulls and the claws of the strange trees

The latest technologies have been used for the study of Mirsura, which also includes Sincrotrine imaging in European Sancutrun (ESRF) for the reorganization of the skull. This revealed a bird -like shape that has a narrow, mostly dental -free snot, an eye socket facing ahead and a large, dome skull. The raid was probably used to remove insects from the holes of tight trees.

Drapanosoromorphus, which is concerned with Mirsura, is known as experts as the most strange creatures of the TRYSK era. They were taken to the lemons, sometimes with a huge claw that is like a Velvisrapator. They had long, barrel -shaped bodies, a long, pre -laughing tail and hand, which causes them to occupy branches like monkeys. Even the species had a hook -shaped claw at the tip of their tail to hang branches.

“Drapanosors have many environmental adaptations and have been known for only a few decades as science. Mirsura was previously in the trees in one of the forests, which emerged after a widespread extinction in the Permanent Traysk. About a novel about Marsura, it is said to be a novel’s skin structure, which makes it a significant extent. The National Museum of Natural History, Washington DC, the United States, who participated in new research.

Melanosoma and skin structures

A thin, gray film was partially preserved in connection with Mirsura. The analyzes confirmed the presence of melanosomes, small argels, including melanin pigments. They are found in most animals, including humans. Researchers compare the shape of the Mirsura melanosoma to those who are found in the skin of living animals, hair and feathers.

“We know that in modern animals, melanosomes have specific shapes associated with tissue where they are found,” says Dr. Validian Russian, co -author of the University College Cork, Ireland Studies.

“Melanosomes found in Mirsura soft tissues are more similar to those found in the current and the wings of the foamic wings than the melanosome found in the hair and the raptile.”

Grugal’s ‘Wonder Ringer Animals’

Fusil Collector Louis Gravoville began digging Jashm from the middle of the middle trousers in Alice in the 1930s. There were also Mirsura’s counselor in search of it. Over the years, it collected a vast reservoir, which has been in the Gargol family for many years.

In 2019, the collection was shifted to the State Museum of Natural History Stuttgart, where Mirsura was discovered during further preparation. The Gwams are in the ancient reservoir of the State Museum of Natural History, Stuttgart.
