Oh? Oh? Oh; Oh : Oh 'oh 'oh! Oh oh oh & oh% oh oh oh @ oh * oh .........

If not, purely for the sake of fun, please type it on a notepad or word document, thank you.

The dinosaurs that flew into the blue sky are: beak-billed dragon, ornithistosaurus, Wukong pterosaur, hatezgot pterosaur, microraptor, etc.

1. Beak-billed dragon:

The beak-billed dragon lived in Germany in Europe and Tanzania in Africa in the late Jurassic, and the beak-billed dragon was 1-2 meters long and weighed 10 kilograms.

2. Ornithistosaurus:

Ornithopod was a Cretaceous carnivorous dinosaur that lived in Europe, weighing 100 kg and measuring 10-20 meters long.

3, Wukong Pterodactyl:

Wukong pterosaurs lived in the late Jurassic period and are about 20-30 centimeters long, the size of a pigeon.

4. Hatezgo's pterosaur:

Hatezgo's pterosaur, which lived in Romania during the Late Cretaceous period about 65 million years ago, was a thick-necked, long-jawed pterosaur with a wingspan of up to 12 meters or more, and an estimated weight of 220 kilograms.

5. Microraptor:

Microraptor (genus name: microraptor) means "small thief" and is one of the smallest known dinosaurs. Microraptors had long plumage on their limbs and tail, confirming the close evolutionary relationship between dinosaurs and birds.

"Dinosaurs Flying to the Blue Sky" is a popular science article written by Xu Xing, which mainly introduces people to a hypothesis proposed 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 the evolution process of dinosaurs flying into the blue sky and changing into birds.

The article not only reveals the major discoveries made by scientists in paleontological research, but also opens the door to the science of paleontology to students, arousing their strong interest in science.

The pterosaur dinosaurs that were born to fly are not really dinosaurs, but people's habitual names.

Pterodactyls, also known as pterosauria, are extinct reptiles with nearly 100 species. Despite being the same era as dinosaurs in their existence, pterosaurs were not dinosaurs. The Greek word for "winged lizard" is an evolutionary clade of flying reptiles.

It lived from the Late Triassic to the end of the Cretaceous, about 210 million years ago to 65 million years ago.

Pterodactyls were the first vertebrates to fly, and the wings of pterosaurs were derived from the membrane located between the sides of the body and the four wing phalanges. Earlier species had long, toothy jaws, and long tails; Later species have significantly shortened tails and lack teeth. Pterodactyls ranged greatly in size, from the small forest pterosaur as a bird, to the largest flying creatures ever seen on Earth, such as the Aeolus pterosaur and the hatezgow pterosaur, with a wingspan of more than 12 meters, teeth 10 centimeters long, and a huge pointed beak.

The process of dinosaurs flying into the blue sky is mentioned in a popular science article written by Xu Xing, "Dinosaurs Flying to the Blue Sky".

The original text is: among them, some predatory dinosaurs gradually became smaller and more bird-like: the bones were hollow and the body was light; skull enlargement, agile movement; The forelimbs are getting longer and longer, and they can flapp like bird wings; They have developed beautiful feathers on their bodies and are 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.

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 while running.

In general, the process of dinosaurs flying into the blue sky is as follows: one branch of dinosaurs in the Mesozoic era evolved over a long period of time and eventually became a soaring bird.

Dear, I hope it will help you and wish you a happy life.

There are also many kinds of dinosaurs, and only one pterosaur can go to the sky. The pterosaurs that could fly into the sky were relatively small and had wings, similar to today's bats, of course, much larger than bats.

Dinosaurs flew into the blue sky, their bodies gradually became smaller and more flexible, and their bodies grew beautiful feathers. Moving to the woods, jumping and landing between the trees, with the ability to glide and finally able to fly actively, the evolution process of dinosaurs flying to the blue sky, the time for dinosaurs to change and change is long, and the characteristics of dinosaurs are diverse and multiplying, and the dinosaur family is huge.

Background of dinosaurs flying into the blue skyAs early as the 19th century, the British scholar Huxley noticed that there are many similarities in the bone structure of dinosaurs and birds, and after studying a large number of dinosaur and bird fossils, scientists proposed that birds are not only related to dinosaurs, but also likely to be descendants of a small dinosaur.

According to this hypothesis, some dinosaurs that are close to birds should have spring feathers, but the relevant fossils have not been found, at the end of the 20th century, Chinese scientists found dinosaur fossils with feather handprints for the first time in western Liaoning, which immediately made researchers all over the world ecstatic.

Dinosaurs wanted to fly not out of longing for the blue sky, but to meet the need for survival.

Dinosaurs forced them to fly into the blue sky in order to avoid natural disasters such as volcanic eruptions or meteorite landings. There are also some predator dinosaur bones that slowly turn into birds; Because there were predatory dinosaurs in order to survive better, the possible reason: a feathered dinosaur that lived on the ground and learned to fly during the run.

Either way, one thing is certain: the flightless dinosaurs eventually turned into birds, and they flew into the blue sky and opened up a new world of life.

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

Dinosaur Profile:

The dinosaurs we refer to are called dinosaurs in the classification of biological systems. Dinosaurs were a group of ancient four-legged reptiles that lived on land for nearly 100 million years and were the rulers of the land at that time. Dinosaurs were the dominant species in the Mesozoic era, and they were found on all continents of the world, including Antarctica, which is now covered in snow and ice all year round.

So far, more than 1,000 species of dinosaur fossils have been discovered. And because of the antiquity and magic of dinosaurs, dinosaurs are also our eternal curiosity and topic. <>

The dinosaur that flew into the blue sky was evolved from one of the predatory dinosaurs, and due to the changes in morphology and living habits, it had the ability to fly, and there were two possible evolutionary processes.

One evolutionary process is that the feathered dinosaurs that lived on the ground learned to fly in the process of running in the Wangqiao Forest, and eventually turned into birds and flew to the blue sky.

One is that predatory dinosaurs gradually become smaller and more like birds, and they move to trees to survive in order to avoid predators or find food, jump and land between trees, and slowly have the ability to glide and fly actively.

Dinosaurs Flying to the Blue Sky Synopsis:

Dinosaurs Flying to the Blue Sky is the text of the 31st lesson of the fourth grade of the Chinese language of the People's Education Edition, written by Xu Xing, this is a popular science article.

This article introduces scientists to a hypothesis based on research that birds are likely to be descendants of a small dinosaur. The text is titled "Dinosaurs Flying to the Blue Sky", which breaks the stereotype of dinosaurs in people's minds and is quite attractive.

The opening chapter describes the bulky, sluggish dinosaur and the light and nimble bird, two unrelated animals in people's impressions, and the article tells the reader 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. <>
