The scientists concluded that while the notion that dinosaur-derived birds is widely accepted in paleontology, there are still a lot of questions that have been raised regarding the problem. this. Up to now, people have not been able to fully explore this whole process and there are gaps in evolution that still cannot be explained. And in fact, paleontologists have also discovered some dinosaurs with a much more suitable flight trait than later birds.
Scientists now believe that the oldest bird still being Archeopteryx living in the late Jurassic was discovered in southern Germany in 1861. Although some older fossils of this species are found in Liaoning, China. National. In addition, although they carry many bird characteristics, Archeopteryx is still classified as a dinosaur.
The fossils of this species all show a variety of body hairs and long, fan-shaped feathers on the wings. However, since 1994, paleontologists have had to “grapple” with a somewhat apocalyptic discovery. The discovery is based on hundreds of “amazing” specimens from China, which reveal many species of dinosaurs also with feathers. These dinosaurs were closely related to the original birds of the evolutionary tree.
Recently, a new species of feather dinosaur was unearthed in China. The fossils store the dinosaurs’ feathers and bones, and provide new information on the dinosaur’s evolution and their origins with the birds.
This newly unearthed dinosaur had feathers, whose feathers were shaped very close to the wing feathers of primitive birds. Scientists named this dinosaur Wulong, which means “dragon dance” in Chinese. Scientists have discovered that the Wulong dinosaur is closely related to the Microraptor in the genus, the Microraptor is a small, four-pointed parrot.
This specimen was discovered many years ago by a farmer in Northeastern China and has since been kept in the Dalian Museum of Natural History. Wulongs are about the size of a crow, while they possess a tail much longer than their body, they have a long snout, mouth full of sharp teeth. The upper body bones are thin and small. The whole body of Wulong has feathers like modern birds, the feathers on the body are fluffy, the feathers on the fore and hind legs are shaped like feathers on the bird’s wings, the tip of their tail has two extremely long feathers.
This new discovery is significant, not only because it depicts a new species of dinosaur, but also because it shows a link between birds and dinosaurs. Dragonflies in their limbs and tails are quite similar to adult birds, while feathers in other parts have many features that make us think of young birds.
For further analysis, scientists need to cut some of the new dinosaur’s bones and place them under the microscope to observe. This technique, known as bone histology, is becoming an integral part of paleontological analysis. But in reality, this process is rarely possible because fossils of paleontological species are always regarded as treasures, thus convincing museums to let researchers cut the fossils. This precious jelly is very difficult.
However, not too long ago, this technique was used to study the Chinese dragon bird – S Dinosauropteryx, a close relative of dinosaurs. The Chinese dragon bird was named after a fossil in Liaoning, China in 1996. Scientists initially identified it as a primitive bird based on its feather trail traits and named it. is “Chinese Dragon”, after further research it was discovered that it was a small carnivorous dinosaur.
The S Dinosauropteryx is a genus of dinosaurs Compsognathidae. Described in 1996, it was the first dinosaur genus outside of Avialae to be found with a distinct feather mark. The S Dinosauropteryx is a small theropoda with an abnormally long tail and short forelimbs. The longest specimen reached 1.07 meters, with an estimated weight of 0.55 kg.
Bone analysis showed that this dinosaur was still immature and not fully mature, but it had a lot of body hair. This is quite different from birds, which often don’t have full feathers until they reach maturity, especially the plumage used to attract females during mating season. However, this immature dinosaur had two long feathers on its tail. Scientists have analyzed that either juveniles need these tail feathers to perform some functions we don’t know about, or that their feathers grow in a completely different way from most living birds.
These dinosaurs were much older than the tyrannosaurs, but amazingly their fossils were beautifully preserved with almost complete bones.
A new study found that feathers appeared 100 million years earlier than birds. Feathers first appeared in the Pterosaurs – the dragon. In fact, there are four distinct types of feathers found on the Pterosaurs, including simple fibers, spun and ribbons, and filamentous Down feather. These feathers are relatively small, which not only changes our view of dinosaurs and birds. It has also changed our views of the feather itself and our understanding of some of the key events of evolution. The origin of the feather can at least be traced back to the origin of the dinosaurs, about 200 million years ago.
Feathered dinosaurs were recovered by scientists based on fossil evidence.
Dr. Maria McNamara from Cork College has studied a new species of dinosaur from Russia – Kulindadromeus shows that the dinosaur’s legs and tail are covered with scales, the whole body is covered with feathers. weird like a beard. What makes people surprised is that on the evolutionary tree, the distance between this dinosaur and the bird was incredibly far, perhaps this was the first dinosaur to possess feathers.
Daniel Erie from Grenoble University, her job is to study the development of feathers in young birds, especially the control of their genomes. She believes that modern birds like chickens often have scales on the legs or neck, and research has shown that our earlier perceptions were not entirely correct, feathers were turned into scales. In fact, the development of scales in reptiles, feathers in birds and cilia in mammals share the same genetic regulatory network. Feathers may have developed very early on.
This breakthrough came in the study of two new species of Pterosaurs from China and many of them have existed as primitive split feathers. And this changed human perception of the origin of feathers, which existed at least 250 million years ago.
This can be traced back to the common ancestor of the Pterosaurs and dinosaurs after the mass extinction in the early Triassic, the terrestrial creatures also slowly recovering from the disaster. To maintain a constant temperature dinosaurs, Pterosaurs and their ancestors also evolved feathers. The appearance of the feathers may initially be to keep warm, while other functions, such as giving the appearance to attract females or even flying, are not considered the original function of the feather.
An international team of scientists analyzed 10 feather fossils discovered in Australia 118 million years ago with fossil feathers deposited in fine mud at the bottom of a shallow lake near Antarctica during the dinosaur era. .
These feather fossils were found in the Geopark located 145 km southeast of Melbourne, Victoria, Australia.
The results of the study showed that dinosaurs used feathers to survive in polar habitats. These Australian fossil feathers are important because they come from dinosaurs and small birds. The first fossil feathers were found in the 1960s and are recognized as evidence of ancient birds, but they have received little scientific attention. Thus, the discovery of “primitive feathers” in Australia suggests that the original function of feathers was to keep warm and help dinosaurs survive in polar regions in cold climates.
