There are many extinct animals in the world, so what are the extinct plants?

The White Mountain Formation fir is a newly discovered rare plant and an ancient remnant plant with a great reputation. The giant panda of the plant kingdom grows only in the Baishan Formation of Zhejiang Province at an altitude of about 1,700 meters. The leaves of the White Mountain Formation fir are strip-shaped, and the earliest cones are green.

Then it turns from yellow to light brown. The Baishan Formation fir has strict requirements for the growth environment, so it is scarce in the harsh environment, and there are only 5 fir left under natural conditions, and the growth of some fir is not optimistic. One plant is getting weaker and weaker.

Bracken appeared in the Devonian era, and the Permian era was extinct. This is the oldest higher plant. Now we can only see ancient ferns in fossils.

Once the ancient fern spread throughout the earth, it was an upright branch with branched branches on it. The surface is smooth and no leaves or roots have grown. There is only one obvious false root.

The stems of the ancient bracken plant were differentiated into the original **pillars. But it is smaller and rarer than the rarest flower in the world. The princess grew in the early Devonian period.

It is one of the extinct plants in the world. The bottom shape shows the word "ball", hence the name. It is a semi-terrestrial plant that usually grows in swamps with no dew on the upper half and no dew on the lower half.

Bracken plants are usually not tall, only about 10 cm, but some can grow up to 25 cm.

Nominally containing about 10,000 species, they are scattered all over the world, and our country is fortunate to account for one-fifth of them, which is the main force in the study of this plant. In fact, bracken plants are not only an important part of forest plants and herbaceous layers, but also have great significance in industry, medicine, food and other industries. However, it should be noted that many of the plants under the name of the bracken plant are endangered, and only a small number are distributed in the mountains in some areas, so some friends mistakenly think that they are weeds or other wild plants, and they can be picked and picked at will.

Taking the poisonous orchid as an example, it is a unique orchid species in China, and is now officially listed as a national second-class protected plant, which contributes its meager strength to species diversity and is an indispensable part of the wild orchid family. It turns out that orchids are not very reproductive, and their natural fecundity is very poor, and it is difficult to breed them artificially. Wild forms of orchids are in a more difficult situation, and the world has put all orchids on the list of protected objects in order to prevent them from being collected at will.

Bracken appeared in the Devonian era, which was extinct in the Permian era and is the oldest higher plant. Also extinct are the Honnei cycads, the naked fern, the reed wood, the seal wood, the scale wood, the lenny fern, and the star wood.

The ancient fruit of China is a plant 4.5 billion years ago. The seed fern was already extinct in the Cretaceous. Bennecycads became extinct in the Oligocene. Late Permian extinction of Ashwagand. The Putuo hornbeam and the Chinese pigeon tree are on the verge of extinction.

I know of snow lotus, which is a very valuable medicinal herb, as well as sandalwood trees, seed ferns, ferns, and workers' woods, all of which are rare and precious plants that have become extinct, which is a pity!

Liaoning ancient fruit, sheep's ear garlic, swamp orchid, Ming codonopsis, stone lip orchid. In fact, there are many, many extinct plants, and we must protect the environment.

The animals that are extinct in the world are as follows:1. The first type: Berber lion The Berber lion mainly lives in North Africa, and the number of this animal is originally very large, but due to poaching, it eventually went extinct.

2. The second type: Caspian tigers mainly live in Iran, Turkey, and Central Asia. Due to the destruction of the habitat, it was thought to be extinct as early as the end of the 2nd century.

3. The third type: thylacine thylacine, also known as the Tasmanian tiger, is a predatory marsupial living in Australia.

In the 21st century, 23 species of animals on the planet have become extinct

Spix macaw, Pyrenees goat, Chinese sickle-winged grouse, Hawaiian crow, Hawaiian honeyspinner, golden toad, Seychelles snail, Madeira white butterfly, white dolphin, Haldridge toad, Liverpool pigeon, Derrick Pie, western black rhino, Javan rhino, Pinta Island tortoise, northern white rhino, golden-capped Hawaiian tree snail, scimitar oryx, coral nudibranch, pan turtle, Panamanian golden frog, Yangtze white sturgeon, vaquita.
