Known as "living fossils", China tree species include: Ginkgo biloba, Cathaya argyrophylla, Davidia involucrata, Fragrant Fruit Tree, etc.
Animals known as "living fossils" in China include: the national treasure panda, and the "living fossil" Chinese sturgeon in the water.
What are the eight living fossils?
First of all, lizards
Lizards are the only known reptiles that survived in the dinosaur era on earth, and their numbers are already very rare. However, due to global warming, this large lizard, known as the living fossil of New Zealand, is in danger of extinction. Studies have shown that the increase in temperature greatly increases the male proportion of large lizards, which may eventually become extinct due to the lack of females.
Second, gabrin sharks.
It is a very special and fierce man-eating shark fish, which often moves in the deep sea. The gray fish skin has a metallic luster and looks very ugly and fierce. Its lips and kisses are longer than fierce and cruel tiger sharks, and its sharp teeth are like an upright triangular knife, and the cold light flashes, which makes people shudder.
Gabrin sharks have an unyielding backbone. They don't want to be taken alive, they'd rather be smashed to pieces. When it is trapped in a fishing net, it will expand through the change of the body pressure of its own swim bladder, and finally explode into large and small pieces by itself, so until 2000, no country in the world has captured a complete gabrin shark; Therefore, there can be no breakthrough in shark research in gabrin. People usually see only fragments of devil fish, and the fracture is uneven, much like broken bricks or porcelain. Their thick skin has almost no toughness and elasticity, especially the fish skin is as hard as ceramic products. The fragments of the devil shark after the explosion are like a piece of porcelain that we usually break, and the fractures can be accurately spliced together.
Third, the sea lily.
Sea lilies are echinoderms, which first appeared in Carboniferous. It lives in the sea, and there are many brachiopods with a flower-shaped body and a calcareous shell on the surface. Because it looks like a plant, people call them sea lilies. The body of sea lilies has a stalk like a plant stem, and the feather at the top of the stalk is their tentacles, also called wrists. These tentacles make people mistake them for plants, just like fern leaves. Sea lily is an ancient invertebrate. Hundreds of millions of years ago, they were everywhere in the ocean.
Four. Coelacanth-like
Coelacanth is one of the oldest fishes in the world and is usually regarded as a living fossil. It was once thought to be extinct as early as 65 million years ago, but it was discovered by humans in 1938. Since then, coelacanth has been called "the living fossil of dinosaur era".
Step 5 limulus
In fact, it is not a real crab, but a primitive arthropod. They have broad disc-shaped bodies and slender needle-shaped tails. Their ancestors can be traced back to CAMBRIAN, but it was not until Jurassic that horseshoes were exhibited. Although there are still five species of horseshoe crabs, they have become less common since the late Cretaceous.
Six, platypus
Platypus is a world-famous rare animal, which is found in southern Australia and Tasmania. It is one of the most primitive mammals in existence. Its tail is flat and wide, and its front and rear limbs are webbed and clawed, which is suitable for swimming and digging. The platypus burrows near the water and feeds on worms, aquatic insects and snails. When breeding, the female platypus lays two eggs at a time, and the cubs lick the milk from the wet hair on the mother's abdomen.
Nautilus
Nautilus, Latin name: Nautilus Pompiplius, English name: ammonite, family and genus classification: Cephalopoda, Tetrabranchia, Nautilus, belonging to mollusks and shellfish. Nautilus is basically a benthic animal, which usually crawls slowly with its wrists at the bottom of deep water of 100 meters. You can also use wrist secretions to attach to rocks or coral reefs. They can swim in the water through inflatable shells or "rush back" by spraying water from funnels. After the storm, on a calm night at sea, Nautilus floated comfortably on the sea, with its shell up, its mouth down and its head and wrist fully extended. These animals are nocturnal, and their main food is benthic crustaceans, especially small crabs.
Eight, musk pheasant, living in tropical South America, has a feather crown. Adult birds are about 22 inches (56 cm) long. The upper body feathers are brown with white spots. * * * and the coat of arms is reddish brown. The exposed skin on the face is blue. When the musk pheasant was born, each wing had two claws for climbing. After three weeks, these two claws disappeared. Musk pheasant crops are huge and divided into two parts, which are used to store and digest the elastic leaves of taro, which is its main food source. Musk pheasant is called smelly bird because it has a strong musty smell in its body.

What are the living fossils in China?
China's "living fossil" plants "living fossil" plants, also known as residual plants, refer to those plant species that survived several Great Ice Age activities in the Cenozoic era. China is known as the "plant kingdom". Many precious plants have long been extinct in other parts of the world, but they have been preserved in the special natural environment of China. Many of these species are called "giant pandas" and "living fossils" in the plant kingdom. They are of great significance to the study of paleobotany, paleoclimatology, paleogeography, geology, plant classification and systematic evolution. There are about 100 species of "living fossil" plants in China, which belong to algae, ferns, gymnosperms and angiosperms. The following is an introduction. 1. Protoalgae belong to algae plants. 1975, Liu Wen, an American algae scientist, discovered a unicellular prokaryotic green algae with chlorophyll a and chlorophyll b in the trench of the cloaca of sea squirts. Later, China scientist Zeng Chengkui and others also found this plant in a sea squirt produced in Xisha Islands. After the research of Chinese and American scholars, it was officially named Protochlorophyta. It is generally believed that eukaryotic green algae evolved from prokaryotic green algae, that is, the original green algae is the ancestor of existing green algae. The discovery of protochlorophyta is considered to be a major event in the evolutionary history of algae. Alsophila spinulosa 2 Alsophila spinulosa, also known as Alsophila spinulosa, belongs to Alsophila spinulosa. Listed as a national first-class protected plant. Alsophila spinulosa is the oldest living fossil in the world and one of the only remaining woody ferns. Alsophila spinulosa is a tree 8 meters high. It is shaped like a coconut tree, and its trunk is cylindrical, upright and straight. There are many large and long pinnate compound leaves clustered on the top of the tree, hanging in all directions. There are many sporangia groups on the back of leaves. Alsophila spinulosa is distributed in Yunnan, Guizhou, Guangdong, Taiwan Province and other places in China, and often grows under forests or in damp places beside rivers and valleys. Alsophila spinulosa is a beautiful ornamental tree species. Its stems are rich in starch, edible and medicinal. It is called "keel wind", which can dispel rheumatism, strengthen bones and muscles, clear away heat and relieve cough. Metasequoia 3. Metasequoia glyptostroboides belongs to the gymnosperms Taxodiaceae. Listed as a national first-class protected plant. 1943, first discovered by China botanist Wang Zhan in Wanxian, Sichuan. After research by Hu Xian and Zheng, it was published in 1948, which immediately caused a sensation in biology. Metasequoia glyptostroboides is a deciduous tree, with a maximum height of more than 40 meters and a DBH of nearly 3 meters. Its trunk is straight and upright, with lush foliage and beautiful trees. Metasequoia glyptostroboides is naturally distributed in parts of Hubei, Sichuan and Hunan, and has been introduced and cultivated from China by more than 50 countries. It has the advantages of fast growth, good material, strong vitality and strong adaptability, and is an excellent fast-growing timber and garden ornamental tree species. 4. Cryptomeria fortunei, also known as the son of Chinese fir, belongs to the gymnosperm Pinaceae. Listed as a national first-class protected plant. Metasequoia glyptostroboides is another "living fossil" plant discovered after Metasequoia glyptostroboides. /kloc-0 In the summer of 955, China botanist Zhong collected a complete specimen for the first time near Guilin, Guangxi. Later, botanists Chen Huanyong and Kuang Keren identified it as a rare plant with only fossils left in most parts of the world, and named it Taxodium ascendens. A good reputation spreads all over the world. It is as valuable as gold. When the world botanists measure the value of specimens in herbarium at home and abroad, they should first look at whether there are specimens of Taxodium, which shows its preciousness. Ginkgo biloba is an evergreen tree with a trunk height of more than 20 meters and a DBH 1 meter. Tall and beautiful, with dense branches and leaves. In particular, there are two silver-white stomatal bands on the back of its green linear blades. Whenever the breeze blows, it is silver, hence the name Yinshan. Cryptomeria fortunei is naturally distributed in Hunan, Sichuan, Guizhou, Guangxi and other places in China, with a small number. Because of the lack of fruit, it is very difficult to raise seedlings, and it has been hidden in the mountains for many years. In order to let Cryptomeria fortunei settle down in Beijing, the capital, China scientists finally cultivated five Cryptomeria fortunei in 1970s after years of efforts, and now they are cultivated in Beijing Botanical Garden. Cryptomeria fortunei is hard and extremely corrosion-resistant, and it is a good material for building, shipbuilding and furniture. 5. Ginkgo biloba, also known as Ginkgo biloba, belongs to the gymnosperm Ginkgo family. It is listed as a national second-class protected plant. Ginkgo biloba is one of the oldest living fossils on earth. About 200 million years ago, it was still distributed in vast areas of the world, but after the Quaternary Glacier, only a few wild Ginkgo biloba survived in West Tianmu Mountain, Zhejiang Province, China. Now it is cultivated all over the world. Ginkgo biloba is a deciduous tree with a height of more than 30 meters and a DBH of nearly 4 meters. This tree looks beautiful. Its leaves are shaped like fans. When the seeds are ripe, they are orange-yellow like apricots and covered with white powder, hence the name Ginkgo biloba. Because of its slow growth, it is called "Gongsun Tree", which means a person's year ... >>
