According to information from IT House on June 6, a scientific team of Central American paleontologists discovered a new species of previously unknown small larceny in the subsurface of the pancreas in the Chanma basin in Tammen, Gansu province. The researcher named it "Chang Ma Dragon". The results were published in the international academic journal Carnegie Museum Yearbook on 4 June.

It's called 鹣 (pron:jiān) from the ancient Chinese mythology of the divine `Big Wing Bird'. The additions were taken from fossils found in Changma town, Tammen, Di Gansu province.

IT House Note: The Sea of the Mountain, the South of the Overseas, states that “Birthbirds are like a twilight, one-sided, flying. And it says, "The South is a little bit more than the South, no less than flying, and it's a name."

The discovery of this new species is expected to solve the long-unsolved “bird bone fragments” of the Changma basin. The region is known for producing a large number of early white bird fossils, and ancient biologists have recorded over 100 prehistoric bird remains.

However, many of these bird bones are not fully preserved, but are fractured and compressed into edible form similar to that of modern owls. Researchers have for many years speculated that there is a large predator feeding on these ancient birds, but have never been able to find direct fossil evidence.

According to Jingmai O'Connell, the deputy director of the fossil-crawling movement at the Field Museum of Natural History in Chicago, “Scientists have found these strange, broken bird bones at this location, and we never knew what caused them. This newly discovered little dinosaur -- the Chang Ma Dragon -- is our best guess. It is the only non-bird dinosaur found in this site, it is carnivore, and it is much larger than everything else we found here.”

The Changma Qilong, a group of feathered dinosaurs with close ties to birds, often known as close relatives of the Raptor, belongs to a small group of Zilong. The only specimens available include parts of the pelvis bones of the shoulder beaks, as well as the gills, sept bones and gill bones on one side. Through the state of skeletal healing and surface characteristics, researchers speculate that the positive specimen is an adult individual. Although only part of the bones were preserved, the fossils were in a three-dimensional state due to the unique preservation conditions of the Chanma group, which allowed for the full preservation of numerous autopsy details.

The researchers found three features in support of thorium as an independent species: The length of the beakbone is longer than the length of the gillbone, reaching 35 per cent of the length of the latter; the end of the gillbone is developing on the side of the head; and there is a visible hole in the abdominal side of the gillbone. The system development analysis confirmed that it belonged to the small group of thieves in the raccoon category.

In terms of body size, the Chang Ma Zhenlong is a “big man” within the family of the little thief. The small pirate dragon is usually small in size, and the most famous is Zhao. On the other hand, the gillbone of the Changma Dragon is about 4 inches (approximately 102.6 mm), according to which researchers speculate that its wings are about 4 feet (approximately 121.9 centimetres) in the same size as a silo.

According to O'Connor, “Chang Ma Dragon is one of the largest pirate specimens found so far”. While the evidence available is mainly from the front limbs, the research team, in combination with the common features of the small larceny, conjectures that the species should be covered with long feathers in both the front and the back limbs, as is the case with their close relatives, thus forming structures similar to the “four wings”. However, such a four-wing look is not equivalent to real power flight. "The gills and other little pirated dragons may not really be able to fly through their muscle-powered wings, but they can glide in the forest like gills." O'Connor explains.

The discovery of the Changma Dragon also expanded the geographical distribution of the small pirated dragons -- from the previously concentrated Liaoxi region to the northwest of the country. More importantly, it is the only non-Bird Dinosaur currently found and named in the trenches, which greatly enriches the biodiversity of the layer.

According to Matt Lamana, a member of the research team and head of the vertebrate paleontology museum of the Carnegie Museum of Natural History, “Chang Ma Dragon reveals that there were also non-bird dinosaurs living in a region known for bird fossils in the trenches. Our team accumulated over 100 bird fossils in Changma, but this is the only non-bird dinosaur specimen. It provides a critical new basis for clarifying the evolution of ancient organisms in the Changma region and the ancient ecological environment of the ancestors of living birds.”

Anti-birds dominate most of the bird species around the world during the era of the white circa. It is, however, incomprehensible that, in certain fossil sites in the ditches of the Chanma basin and in the hot river biota, real birds have a clear advantage over fossil populations and species diversity.

There are different interpretations of this anomaly: some scholars believe that these two layers are relatively late and coincide with an important stage in the early rise of real birds and their gradual replacement with other early birds; but uncertainty over the later years leads to doubts about the hypothesis.

According to another view, the two layers may have recorded a unique and rare and similar habitat that is suitable for the survival of large numbers of real birds, and thus the fossils dominate. The research team preferred the second view in the present study, noting that the current research on the bipolar ancient environment is still very limited and that the reasons behind its unique biological composition need to be further explored.

O'Connor added: “Retroactive origin is the key to understanding life on Earth today. Birds are one of the most successful groups of terrestrial vertebrates today, and researching early birds and their near non-bird dinosaurs can help us identify the unique evolutionary advantage that birds escape extinction and continue to this day.”
