What are the specific types of dinosaurs? What kind of dragons are they specifically called? Can there be pictures to illustrate them?

1) Brontosaurus:

Some dinosaurs are very large, such as Brontosaurus. During the Jurassic, the climate on Earth was warm and humid, and there were lush forests everywhere. Because of these abundant plant foods, herbivorous dinosaurs flourished. Brontosaurus was also active on the plains of what is now North America at this time. superior.

The weight of Brontosaurus is about thirty-five to fifty tons. Its thick legs are like tree trunks; its long neck is as tall as a seven-story building when it stands upright. It can be said that it is The largest animal on earth. Although the body of the Brontosaurus is astonishingly large, its temperament is very gentle. It usually feeds on plants in temperate forests, and sometimes walks into swamps. Because the water has buoyancy, it can reduce the heavy burden on its body and at the same time avoid strange creatures. Attack by a ferocious carnivorous dinosaur like a dragon.

(2) Three Chisaurus:

The bone plates and bone fragments on Stegosaurus and Ceratopsaurus can only be used for passive defense and cannot fight back. The situation gradually changed when the dragon appeared. The three-faced dragon is the largest among the dragons. It has two spear-like horns on its head, and the other horn protrudes between the eyes and nostrils. Such a sharp weapon would defeat even the most terrifying carnivorous dinosaurs.

(3) Stegosaurus:

Stegosaurus appeared 150 million years ago. Its biggest feature is the two rows of bone plates on its back and the growth of its tail. With sharp spines. Stegosaurus is a herbivorous dinosaur that moves slowly. The bone plates on its body and the spikes on its tail have become the best defense against carnivorous dinosaurs.

(4) Ankylosaurus:

Stegosaurus is protected by bone plates, but areas that are not covered by the bone plates are still vulnerable to attack. When the stegosaurus gradually became extinct, the ankylosaurus (armadillo dragon) covered with bone plates took its place. Ankylosaurus is like an invulnerable tank, even Tyrannosaurus rex is helpless against it.

(5) Tyrannosaurus rex:

Tyrannosaurus rex (Tyrannosaurus rex) is the largest and most brutal carnivorous dinosaur. The time when Tyrannosaurus rex appeared was already at the end of the dinosaur age. About 80 million years ago. Tyrannosaurus rex's body was fourteen meters high and weighed about ten tons. Its hind legs were so thick and strong that they could even support a rhino each.

From the fossils of Tyrannosaurus rex, each of its teeth is as big as an adult's hand, and even its eyes are larger than a human head. Although most of its body is astonishingly large, the pair of forelimbs of Tyrannosaurus rex are small and short, so short that it cannot even put food into its mouth. Murderosaurus also has the same habits as Tyrannosaurus rex and is very ferocious. animals.

﹝６﹞Acodonosaurus:

Acodonosaurus, like Tyrannosaurus rex, appeared at the end of the dinosaur age. The most special thing about Anatosaurus is its head. Its flat and long jawbone resembles a duck's mouth, hence the name Anatosaurus. In the past, people thought that Anarosaurus lived a life similar to that of a duck, swimming in the water and living on water plants. Later, when scientists studied the fossils of Anatosaurus, they discovered that they did not live on aquatic plants, but on trees on the shore. Aegosaurus also had the same habit.

(7) Iguanodon

One day in March 1822, the weather was very cold, but Mr. Mantel still went out to see patients as usual. The wife was waiting for her husband to come back at home, always worrying whether he would catch a cold. Later, Mrs. Mantel couldn't sit still anymore, so she took a piece of her husband's clothes and went out to meet him in the direction of his visit. She was walking on a road that was being built. The newly dug steep walls on both sides of the road exposed layers of rocks. She habitually observed the newly exposed rock formations on both sides while walking. Suddenly, something shiny caught her attention. "What is this?" she said to herself, and stepped forward to take a closer look. Wow! It turned out to be some strange-looking animal tooth fossils. The fossil teeth were so big that Mrs. Mantel had never seen such large teeth. The excitement of the discovery made Mrs. Mantel forget to give her husband clothes. She carefully removed the fossils from the rock formations and brought them home.

Later, Mr. Mantel returned home. When the lady presented the newly collected fossils to him, he was stunned. He had seen many fossil teeth of ancient animals, but none of them were similar to such a large and strange tooth.

Shortly afterwards, Mr. Mantel found many such tooth fossils and related bone fossils near the location where the fossils were found. In order to find out what animals these fossils belonged to, Mr. Mantel brought these fossils to the French naturalist Cuvier and asked the most famous scholar in the world at that time to identify them.

To be honest, Cuvier had never seen such fossils, and all the books and papers he had read written by senior scientists had never mentioned such fossils. However, Cuvier still made a judgment based on his considerable zoological knowledge. He believed that the teeth were from rhinoceros and the bones were from hippopotamus, and they were not too old.

Mr. Mantel was very skeptical of Cuvier's identification. He thought Cuvier's conclusion was too hasty. He decided to continue his research. From then on, whenever he had the chance, he would go to museums around the world to compare specimens and review data.

One day two years later, he accidentally met a naturalist working at the Royal Academy Museum in London. The man was studying a modern lizard living in Central America, the iguana. So Mr. Mantel took those fossils to the Royal Academy Museum in London and compared them with the iguana teeth collected by naturalists, and found that the two were very similar. The overjoyed Mr. Mantel concluded that these fossils belonged to an extinct ancient reptile similar to iguanas, and named them "iguana teeth."

Later, as more and more fossil materials were discovered, humans had a deeper and deeper understanding of these ancient animals. We knew that the so-called "iguana teeth" were actually species of A member of the diverse dinosaur family; it is indeed a reptile like the iguana, but it is more distantly related to the real iguana than to other species of dinosaurs! However, according to the rules of biological nomenclature, the Latin text of the species name of this earliest scientifically recorded dinosaur has not changed, and it still means "iguana's tooth". However, its Chinese name is translated as Iguanodon.

So remember: Iguanodon is the earliest dinosaur recorded in scientific history. At the same time, don’t forget the name Mantel and his nature-loving wife.

There is a small place called Lewes in Sussex, southern England. 180 years ago, a country doctor named Mantel once lived here. Mr. Mantel was full of curiosity about nature and especially loved collecting and studying fossils. When he was not practicing medicine, he often took his wife to climb mountains and wade in rivers to search for and collect fossils. His footprints were all over the ditches and ridges with exposed rock formations around him. Over time, Mrs. Mantel also became a "friend of nature" and an expert in fossil collecting.

(8) Psittacosaurus

However, it was not until the Mantels discovered the Iguanodon and compared it with the iguana that the scientific community initially determined that this was a similar species. An extinct reptile based on lizards. Therefore, the names of new types of dinosaurs and other ancient reptiles discovered subsequently were all related to lizards, such as "whale-like lizards", "forest lizards" and so on. At the same time, because these ancient animal fossils that first attracted people's attention are often huge and grotesque, they are really scary.

As the fossils of these terrifying and lizard-like ancient animals continue to be discovered and excavated, more and more types of them have accumulated, and many naturalists have begun to realize that they play an important role in animal classification. Learning should be self-contained. In 1842, the British paleontologist Sir Owen created a name for them in Latin. This Latin word consists of two roots. The former root means "terrible" and the latter root means "lizard". Since then, "horrible lizards" have become a collective name for this large group of reptiles that are related to each other, but behave in a variety of ways. We Chinese have both imagination and generality, so we translated this Latin name into "dinosaur".

(9) Mamenchisaurus

Now we know that there are indeed many terrifying giants in the dinosaur family, but there are also some small and cute "little things". If you go to the Chinese Palaeozoology Hall not far to the west of the Beijing Zoo, you will see a variety of dinosaurs of different sizes and shapes, from Psittacosaurus, which is less than 1 meter long, to Mamenchisaurus, which is 22 meters long. It will give you a more comprehensive understanding of the dinosaur world.

(10) Ssangyong

Ssangyong has a relatively stout body, a tall skull, well-developed jaws, a large mouth, and a mouth full of teeth like sharp knives, with the front and rear edges of the teeth There are also small serrated teeth on it, which indicate that it can tear up any captured prey and then swallow large pieces of meat into its belly. In addition, there are holes in the skull of Ssangyosaurus behind the eyes. These holes are used to better attach the muscles that affect the jaw bones, so the bite of Ssangyosaurus must be very powerful. Scientists speculate that Disaurus may have been the most ferocious and ferocious predators in the early Jurassic ecosystem.
