China has a long history, there are many animals and plants known for living fossils in our country, the plant known as the living fossil has ginkgo, and the animals known as the living fossil have the Chinese alligator, the national treasure panda, the giant salamander, and the Chinese sturgeon.

Giant pandas

Giant panda must be familiar to every Chinese, as a unique national treasure in China, in fact, giant pandas have survived on the earth for more than 8 million years, which means that the history of giant pandas is actually longer than humans.

Chinese sturgeon

In addition to pandas, China's Chinese sturgeon actually has a long history of more than 100 million years, and there are not many fish in the world that are so old and long, and they are also protected animals in China. Some scientists say that the Chinese sturgeon actually has a very high scientific research value, because some traces of biological evolution can be seen from the Chinese sturgeon.

Alligator

The number of Chinese crocodiles in the world is very small, and this book is a kind of crocodile endemic to China, and people usually call the Chinese alligator a pig Po Dragon, which is now endangered.

Giant salamander

This animal is huge, the whole body can be up to one meter, or about one meter, the weight can reach more than 100 catties, and it looks a bit like a lizard, but it is fatter and flatter than a lizard. This animal generally lives in waters with relatively clear water and low sediment content.

Ginkgo

Ginkgo biloba, also known as the white fruit tree, is also one of the living fossils in China, in ancient times ginkgo was also called the duck's foot tree or the Gongsun tree. Compared with many plants, ginkgo biloba is actually a higher plant, his history is very long, it has lived on this earth for more than 170 million years, just like dinosaurs, at that time all over the world, and then the dinosaurs became extinct, but ginkgo biloba is very rare in China.

Chinese living fossils include: Chinese sturgeon, giant panda, giant salamander, Chinese alligator, ginkgo, metasequoia, etc. 1. Giant salamander:

There is the largest one of the existing tail orders, among the amphibians, it is the largest, the total length can reach 1 meter to 1.5 meters, the heaviest weight can exceed 100 catties, similar to a lizard, the body is fat and flat, with four legs, mainly inhabiting mountain streams, or in dark caves, poor eyesight, sensitive hearing, no eyes and face. 2. Chinese sturgeon: a national first-class protected animal, with a history of more than 100 million years, nowadays, there are not many ancient fish, and traces of biological changes can be seen from it.

3. Giant panda: referred to as national treasure, is a unique national treasure protected animal in China,-- has only survived on the earth for more than 8 million years, and survived earlier than humans, according to the latest research, it appeared in the late Miocene at the latest. 3. Chinese alligator:

It is a kind of crocodile endemic to China, commonly known as Pig Polong, Tulong, and is one of the smallest crocodile species in the world. It is mainly distributed in the middle and lower reaches of the Yangtze River. It is both ancient and one of the very few reptiles in the world that survive in very rare numbers and are on the verge of extinction.

4. Ginkgo biloba: Ginkgo biloba tree is also known as the white fruit tree, and was known as the duck's foot tree or Gongsun tree in ancient times. As far back as 270 million years ago, the ancestors of ginkgo began to appear, and compared to the plants of that time, it was still a higher plant.

Later, most of the ginkgo slowly became extinct with the dinosaurs, and a few ginkgo survived, and gradually, it became a rare treasure. 5. Metasequoia Chana: It was the same era as the ginkgo tree, but since the end of the mass extinction, it has been rare to see.

Animal: Giant panda. Plants: Ginkgo, Metasequoia, Dove tree, fragrant fruit tree.

1. Giant panda:

As a unique national treasure in China, the giant panda has lived on the earth for more than 8 million years, and it has survived on the earth much earlier than humans. Because they have changed themselves in the changing environment, they have not disappeared from the chain of the biosphere, thus becoming one of the few living animal fossils in the world.

2. Ginkgo: More than 270 million years ago, the ancestors of ginkgo began to appear, and compared with the ferns that spread all over the world at that time, it was still a higher plant. More than 170 million years ago, ginkgo biloba has spread all over the world like the dinosaurs that dominated the world at that time, and later, most of the ginkgo biloba became extinct like dinosaurs, and only a little bit was preserved in some parts of China.

3. Metasequoia: Metasequoia is not only a precious "living fossil", but also it has strong vitality and wide adaptability, grows rapidly, and is an excellent green tree withered sap species, which has not only been widely cultivated in various parts of China, but also competed to introduce and cultivate this precious tree in the world.

4. Dove tree: Dove tree is a world-famous precious ornamental tree, often planted by the poolside, beside the stream and near the sanatorium, hotel and exhibition hall, and has a symbolic meaning of peace. The material is heavy, and it is the best material for construction, which can be used to make furniture and carving materials.

5. Fragrant fruit tree:

Deciduous trees. The leaves are opposite, stalked; Leaves broadly elliptic or broadly ovate-elliptic, entire; The leaves are triangular-ovate and early falling. It is distributed in Jiangsu, Anhui, Zhejiang, Qinjiang, Jiangxi and southwestern provinces.
