What living fossils are there? Want to know what living fossils are?

Living fossils are:1. Ginkgo biloba:

Ginkgo biloba is the only surviving species of gymnosperms Ginkgo biloba. Tianmu Mountain, Zhejiang.

Wild ginkgo biloba can still be seen in the area. Therefore, ginkgo biloba is known as a "living fossil" and a "panda" among plants.

2. Metasequoia:

Metasequoia is not only a precious "living fossil", but also it has a strong vitality and a wide range of adaptability, grows rapidly, is an excellent greening tree species, not only has been widely cultivated in various parts of our country, many countries in the world are also vying to introduce cultivation, so that this precious tree grows endlessly in the world.

3. Chinese sturgeon:

The Chinese sturgeon has a long history of more than 100 million years, and there are not many fish that are so old. Biological evolution can be seen in it.

Some traces of the species, so they are called living fossils in aquatic organisms, which have high scientific value.

4. Chinese alligator:

The Chinese alligator is both ancient and a very rare reptile that is on the verge of extinction in the world.

In the Chinese alligator, early dinosaurs can still be found to this day.

Many characteristics of reptiles. Therefore, people call the Chinese alligator a "living fossil".

5. Giant panda:

Giant pandas have lived on the earth for at least 8 million years, and are known as "living fossils" and "China's national treasures", that is, national beasts.

It is the flagship species of the world's biodiversity conservation.

The Chinese tree species known as living fossils are: Ginkgo biloba, Alder spinosa, Silver Fir, Dove tree, Metasequoia, Eucommia ulmoides, Fir tabulae, Hemlock fir tree, Hemlock fir tree, Pinus chinensis, Taiwan fir, Tricuspid fir tree, Yew chinensis, Cinnamomum chinensis, Gongshan three-pointed fir tree, Himalayan yew, Yunnan quill tree, fragrant fruit tree, etc.

Animals that are known as living fossils in China include the giant panda, the national treasure, the Chinese sturgeon, etc.

Extended information: Living fossils, which can be vaguely referred to as relict organisms, refer to any organism whose analogous species exist only in fossils, and there are no other extant similar species. These species once survived major extinction events and retain their original characteristics from the past.

Some of the ancient species of living organisms that exist are non-scientific terms.

The definition of a living fossil is generally the discovery of a fossil before the discovery of a living body, or the existence of a living body of the same genus as the identified fossil.

Living fossils refer to species with a long origin, widely distributed in the Tertiary or earlier of the Cenozoic Era, and most of the species have been extinct due to geological and climatic changes, and the shape of these existing organisms is basically the same as that found in fossils, retaining the original shape of their ancient ancestors. Most of its relatives are extinct and relatively isolated, and organisms that evolve slowly can be called relict organisms or living fossils.

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.

Common living fossils include giant panda, nautilus, horseshoe crab, platypus, Chinese sturgeon, Latimai fish, giant salamander, mole, platypus, tapir, Komodosaurus, coelacanth, ginkgo, alder, silver fir, dove tree, metasequoia, eucommia, fir oil, hemlock, hemlock, water pine, three-pointed fir, coarse quinquet, yew, citron, Gongshan three-pointed fir, Yunnan quincilla, fragrant fruit tree, etc.

Introduction to Giant Pandas.

Giant pandas belong to the carnivorous order Ursidae, the only mammal in the genus Giant Panda. There are only two subspecies. Males are slightly larger than females. The body is fat and bear-like, plump and rich, with a round head and a short tail, a long head and torso, and a tail length of 10-12 cm.

Introduction to Nautilus.

Nautilus is a common name for marine mollusks of the class Cephalopoda and the family Nautilidae. There are 2 genera and 6 species, with a curly pearl-like shell, and the maximum size of the shell can be centimeters, but the adult nautilus generally does not exceed 20 centimeters. The nautilus is the smallest species in the nautilus family, generally only 16 cm.

Introduction to the platypus.

The platypus is one of the most primitive mammals, it is an incomplete mammal, there are very few species, there is only one animal in the same genus, the platypus, and it is also one of the lowest mammals; In the late 18th century, George Shaw received specimens of the platypus, believing that the creature was the product of a prank, and named it in 1799.
