Dinosaurs are the animals that have lived on the earth for the longest time, and they also have their own languages. They lived happily on the earth about 200 million years ago, but later they didn't know who and why they ended the dinosaur era. At that time, I seemed to feel their fear and they growled helplessly.
Finally, scientists tried to explore the reasons for the extinction of dinosaurs. Finally, science finally figured out how dinosaurs died out because of the great destruction of the earth that happened 6500 years ago. What appeared on the earth was a big comet. At that time, when the great comet was still far away from the earth, the temperature of the earth rose rapidly until it was several hundred degrees or even higher.
Scientists speculate that when the comet landed, it exploded in every corner of the earth. The whole world was killed by the heat, only Madagascar was still intact, but in the next few minutes they encountered a more terrible disaster. It was a tsunami. They finally became extinct.
Through these, I learned that human power can't resist nature, and all we can do is protect the environment.
After reading Encyclopedia of Dinosaurs 2, the book is rich in content and the description of dinosaurs is very vivid. There is a lot of information about dinosaurs in it, which makes me know a lot about dinosaurs.
I know the origin of dinosaurs and the time when they lived. There are: Jurassic, Cretaceous, Cambrian, and so on. This is the era in which they live. These dinosaurs evolved from single-celled organisms to these strange dinosaurs in order to survive!
I also know their types and appearances: some fly in the sky, such as toothless pterosaurs, some run on land, such as sawtooth dragons, some fierce predators, Tyrannosaurus Rex, and some incarnations of love. Finally, there is the water killer ichthyosaur.
From this book, I know a lot of dinosaur encyclopedias that I didn't know before. I think there must be a lot of knowledge waiting for us to explore
Random thoughts on dinosaur encyclopedia 3 Today, my father and I went to Xinhua Bookstore to buy books. Suddenly, I was deeply attracted by a set of books called my first encyclopedia. There are ten books in this set, including the encyclopedia of unsolved mysteries, the encyclopedia of wonderful human body, the encyclopedia of natural mysteries, the encyclopedia of animal world and so on. I asked my father to buy me a set of books. As soon as I got home, I couldn't wait to read my favorite dinosaur encyclopedia.
The protagonist of this book is that there were some powerful masters on the earth who once ruled the world 1. 600 million years ago. The so-called dinosaurs simply refer to the reptiles on the earth during the Mesozoic era, but neither pterosaurs in the air nor sea dragons in the water are dinosaurs. Dinosaurs also evolved, first Precambrian, Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, Cretaceous, and finally Tertiary and Quaternary.
After reading this book, I know that the earth is constantly changing. Under the action of various natural erosion, the mountains on the land were gradually razed to the ground, and gravel accumulated on the seabed, gradually forming mountains ... I also know something about the reasons for the extinction of dinosaurs, which may be due to climate, meteorite impact, volcanic eruption or other relations. Up to now, this is still a mystery.
After reading this book, I know some mysteries of dinosaurs. I hope scientists can further explore the secrets of dinosaurs! I also hope to solve these mysteries by myself when I grow up!
After reading the dinosaur encyclopedia, I finished reading the book dinosaur encyclopedia very early and liked it very much. One of my favorite dinosaurs is Allosaurus. Allosaurus has sharp claws that can knock down the opponent's thick tail and long and powerful hind legs, which is very suitable for running. Although Allosaurus is not as famous as the famous Tyrannosaurus Rex, Allosaurus has an advantage over Tyrannosaurus Rex in hunting opponents. Allosaurus also had more teeth than Tyrannosaurus Rex. Tyrannosaurus Rex had 60 teeth, but Allosaurus had 70 teeth, each of which was as sharp as a dagger with jagged edges. If a tooth falls out somewhere, it will grow out immediately, which is creepy. But also in groups, attack together, almost never failed. At that time, scientists thought that Allosaurus was the most deadly carnivorous dinosaur in the world, but the descendants of Allosaurus, the southern behemoth, were more fierce than Allosaurus.
I like Tyrannosaurus rex second. Tyrannosaurus rex can reach more than 40 kilometers per hour. It can stand up as high as two buildings, with developed hind legs and muscles. Its teeth are the sharpest among dinosaurs, with 60 teeth, and the longest tooth is 18 cm. It can eat a person's body. Such a perfect dinosaur, I believe that no animal can escape his pursuit. But this Tyrannosaurus rex is so horrible to any living thing, but it is very horrible to propose marriage. If a male Tyrannosaurus Rex wants to propose to a female Tyrannosaurus Rex, he must bring his own prey. If this prey can't satisfy the female Tyrannosaurus rex, the male Tyrannosaurus rex is likely to become a delicacy for the female Tyrannosaurus rex.
After reading the dinosaur encyclopedia, five dinosaurs once dominated the earth 1. 600 million years. In the Mesozoic era, they created countless unprecedented glories and created a dinosaur empire, which wrote millions of poems for science and technology. After reading this book, I learned a lot about dinosaurs. I learned a lot about the dinosaur family.
Before the birth of dinosaurs, the world changed many times, including Precambrian, Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian. Dinosaurs appeared in Triassic, Jurassic and Cretaceous, animals appeared in Tertiary and apes appeared in the fourth season.
In Triassic, the continents on the earth were all connected, and people called it Pangu continent. Dinosaurs include Stegosaurus, Ankylosaurus, Hornbill, Ceratosaurus, Polypodiaceae, Birds, Tyrannosaurus Rex, Allosauridae, sauropods and theropods.
Now, dinosaur fossils are very precious, and it is good that only one dinosaur in 1 10,000 becomes a fossil. The fossils found are only a small part, so dinosaur fossils are very precious.
The precious topic of dinosaur extinction has puzzled us for many years. Some people say that the planet hit the earth, causing dust to cover the sky, and plants died before seeing the sun. Herbivorous dinosaurs starved to death because of lack of food, and carnivores lost their food sources and finally died. There is also the possibility that volcanic eruptions will lead to climate change.
In short, the dinosaur family created countless glories and wrote poems for science. It adds more colors to archaeology and makes people know more knowledge. It is really amazing to make the originally boring world of Triassic, Jurassic and Cretaceous full of vitality.
Dinosaur Encyclopedia 6 "Encyclopedia of Dinosaur World" is a good book that is very popular with children. I couldn't wait to open it as soon as I got it.
The title page of the book is a beautiful picture of a strong Allosaurus catching food, which is very attractive. Let's get on the time machine and go back to the world at that time to see their style.
This book is divided into five chapters: revealing the dinosaur era, returning to Triassic, Jurassic trip, and visiting Cretaceous and dinosaur neighbors. There are all kinds of dinosaurs in it, some are agile and some are huge and bulky. Herbivorous dinosaurs, such as Mamenxilong, Stegosaurus, Lei Long, etc. There are carnivorous dinosaurs, such as Tyrannosaurus Rex, Pterosaur, Allosaurus and so on. At that time, dinosaurs were everywhere in the world, flying in the sky, running on the ground and swimming in the water. ...
I am most interested in Tyrannosaurus Rex, the king of dinosaurs! Did you start to tremble when you heard the name? It lived in the late Cretaceous and ruled North America and the eastern Asian continent for a long time. At that time, almost no dinosaur could be its opponent.
After reading this book, I learned a lot about dinosaurs, which really benefited me. But now both cute herbivorous dinosaurs and fierce carnivorous dinosaurs are extinct. They are all life. They used to be the masters of the earth. Due to the destruction of the living environment, many animals and plants on the earth are now on the verge of extinction. It takes tens of thousands or even hundreds of millions of years to evolve a species, but once it is extinct, it will never come back. Without them, bionics will have no source of inspiration and can't get better development. Let's protect nature and the earth together!
Although I have never seen a real dinosaur after reading Encyclopedia of Dinosaurs 7, if you ask me what my favorite animal is, I will answer: dinosaurs. To this end, my parents bought me many books about dinosaurs, and we also went to the museum to see dinosaur fossils. Encyclopedia of Dinosaurs is one of my favorite books.
After reading this book, the first thing I admire is the spirit of archaeologists and dinosaur scientists who keep studying. Because dinosaurs died out 65 million years ago, we don't know what the dinosaur world is like. But archaeologists and dinosaur scientists can restore the true colors of dinosaurs based on a fossil and archaeological discovery, so that all kinds of dinosaurs can come back to books vividly and tell us interesting stories. And they are still trying to discover new dinosaur secrets. Even like Jurassic Park, DNA was extracted from primitive mosquitoes to keep dinosaurs alive. Although science shows that it is difficult to really revive dinosaurs, just like looking for a needle in a haystack, who says that we can't create miracles without fear of failure, fearless adventure and exploration, and scientific and technological progress?
In fact, the dinosaur family that ruled the world for 65.438+75 billion years before human beings was as powerful as human beings, but this powerful overlord suddenly disappeared from the earth without a trace. Scientists have never found the cause of the extinction of dinosaurs, but they have put forward many conjectures. Some people say that volcanic eruptions lead to lava flows, some people say that asteroids hit the earth, and some people say that the climate change of the earth leads to the perpetuation of dinosaurs. I think we humans should be smarter than dinosaurs, we should be able to find out the reasons for the extinction of dinosaurs, and we can protect the earth through our efforts. Nowadays, mankind is destroying the earth's environment, air pollution, global warming and the growth of animals and plants more seriously than ever before. Protecting the environment, protecting human beings and changing our air, water, animals and plants is everyone's responsibility on earth. If we don't pay attention to these things, then mankind may become extinct next. Therefore, we should start from a young age, start from small things and protect the environment.
Encyclopedia of dinosaurs taught us to love science and the earth.
