What dinosaur flew into the blue sky and turned into a bird?

Personally, I think that pterosaurs, pterosaurs can fly, with the change of the environment, the scarcity of food, the large individuals slowly die, the small individuals gradually become active, the last generation of generations, feathers are also likely to be the body of the original hair. For example, some people have more body hair, and some have less body hair, because of environmental selection, the more body hair in the pterosaur gradually evolved into feathers. The evidence is probably a sharp mouth.

The pterodactyl's beak was also pointed, like the beak of a bird.

When it comes to dinosaurs, people often think of the ferocious Tyrannosaurus rex or the bulky, sluggish Mamenxi dragon; When we think of birds, we naturally think of light pigeons or colorful peacocks. The two may seem unrelated, but a large number of fossils discovered in recent years show that during the Mesozoic era, one branch of the dinosaur evolved over a long period of time and eventually became a soaring bird.

Probably a pterosaur. Because the pterosaur itself could fly, it may have grown feathers as the environment changed, and became a later bird.

Hello, this one should be a pterosaur. Pterodactyls themselves could fly in the age of dinosaurs and were the overlords of the air.

They may be hairy, they may practice while running, or they may jump between the trees to slowly develop their flight function.

Dinosaurs with feathers that can fly into the blue sky.

However, some scientists believe that flight does not begin with arboreal life. They speculated that a feathered dinosaur that lived on the ground learned to fly as it ran.

The body gradually becomes smaller, and it looks more and more like a bird, with hollow bones and a light body; skull enlargement, agile movement; Their forelimbs grew longer and longer, flapping like bird wings, and their bodies grew beautiful feathers, no longer covered with scales or scale armor.

Some of these species may migrate to trees to survive in order to escape predators or to find food. These arboreal dinosaurs jumped and landed from tree to tree, slowly gaining the ability to glide and eventually take their own flight.

The principle of pterosaur flight

The wing membrane structure that supported the flight of pterosaurs was completely different from the wing structures of vertebrates, birds, and bats that were able to fly later. Pterodactyls formed a wing surface from the epithelium, a membrane of muscles, and other soft tissues that stretched from the thorax to the extremely long fourth finger.

The membrane is supported by other phalanges. The membrane of the pterosaur was attached to only a slender finger that extended posteriorly along the side of the body to the knee; There is an additional epithelia between the neck and the arm. The front three phalanges are claw-shaped, slender hooks.

Its membranes appear to be fully adapted to flight and gliding, but are not as flexible and fragile as the membranes of bats or the wings of birds. The body is strong, with long, thin hind legs, the structure of which suggests that it is not adapted to vertical movement or rest, and is suspended by hind limbs when resting.

Dinosaurs Flying into the Blue Sky mainly writes about a hypothesis put forward by scientists based on research: birds are likely to be descendants of a small dinosaur. At the end of the 20th century, Chinese scientists discovered dinosaur fossils with feather imprints for the first time in western Liaoning, which provided evidence for people to imagine that dinosaurs flew to the blue sky and changed into the evolution process of birds.

The text is about dinosaurs flying into the blue sky, which breaks the stereotype of dinosaurs in people's minds and is quite attractive. The article begins with a vivid presentation of the bulky, sluggish dinosaur and the light and nimble bird, two seemingly unrelated animals in people's minds.

Tell us that during the Mesozoic Era, one branch of the dinosaur evolved into a soaring bird, and then introduced the general process of this scientific discovery.

Specifically, it is about the evolution of dinosaurs into birds.

Here's why dinosaurs flew into the blue sky:

1. It may be a feathered dinosaur that lived on the ground and learned to fly during the run.

2. Feathered dinosaurs that may have lived on the ground learned to fly in the process of running, and the dinosaurs turned into birds and flew into the blue sky.

3. It is also possible that dinosaurs forced them to fly into the blue sky in order to avoid natural disasters such as volcanic eruptions or meteorite landings.

The Significance of Studying Dinosaurs:

The significance of studying dinosaurs includes two categories: theoretical significance and practical significance. Let's start with the theoretical implications. Dinosaurs mainly lived in the Mesozoic Era, and the end of the Jurassic was the heyday of dinosaurs, and they became extinct in the Cretaceous.

Therefore, in the Mesozoic strata, many non-avian dinosaur fossils can be found, but in the Cenozoic strata, there are no non-avian dinosaur fossils at all. Therefore, a very important significance of studying dinosaurs is that the macro rolling beam helps us determine the age of the strata. In addition, different species of dinosaurs have different habitats, so studying dinosaurs can also help us determine a series of paleoenvironments, such as paleoclimate, paleolandforms, etc.

In addition, the study of dinosaurs can also strengthen the understanding of biological evolution and analyze the ecological environment at that time more clearly. The existence of dinosaurs also confirms the evolution of vertebrates. At the same time, dinosaurs can become a species that dominates the world, and they must have fought for survival between the same species and different species, and being able to stand at the top of the food chain also reflects the evolutionary theory of natural selection and survival of the fittest.
