Who are the living fossils of animals and plants, and what are the plants and animals of living foss

Ginkgo, which first appeared in the Carboniferous period 100 million years ago, is a "living fossil" in the plant kingdom.

It is a relict plant left over from the Tertiary of the Cenozoic Era 10 million years ago.

Giant pandas, which have survived in China for more than eight million years, are known as "living fossils".

The Chinese alligator, which scientists have found to have characteristics similar to dinosaurs, is a very old reptile and is therefore called a "living fossil".

The Chinese sturgeon is a first-class protected animal in China, which first appeared in the Early Triassic 230 million years ago.

"Living fossils" refer to some of the ancient species of organisms that exist, which can be roughly understood as "relict organisms", that is, organisms that have survived major ancient extinction events and retain the original characteristics of the past. It's not that "fossils dug up from the ground come back to life".

Among the animals, the "living fossils" are: nautilus (from the age of trilobites to the present), Chinese sturgeon (from the age of dinosaurs to the present), alligators (contemporaries of dinosaurs), giant pandas (millions of years ago), giant salamanders (salamanders, ancient amphibians), horseshoe crabs (as old as trilobites).

The "living fossils" in the plants are: ginkgo biloba (older than the dinosaurs), dove tree (more than 10 million years old), metasequoia (contemporaneous with the dinosaurs), pine fern and alder (the main food of the dinosaurs).

Giant pandas are known as living fossils of animals, and alders are living fossils in plants.

The miraculous coelacanth is an important part of the evolution of marine animals to land animals.

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 greening tree species, which has not only been widely cultivated in various parts of China, but also competed with many countries in the world to introduce and cultivate, so that this precious tree grows endlessly 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, Jiangxi and southwest provinces.

The plants and animals that are known as living fossils are:

1. Gablin shark.

The Gablin shark is a very special and ferocious man-eating shark that often moves in the deep sea. The gray fish skin is shining with a metallic luster, it looks very ugly**, the lip kiss is longer than the fierce and cruel tiger shark, and it is even sharper, and the sharp teeth are like an upright triangular knife, the cold light is flickering, and the appearance is very hideous and terrifying, which makes people shudder.

2. Giant lizard withered lizard.

The giant lizard is the only reptile that has survived the dinosaur era on Earth, and its population is very rare. But due to ongoing global warming, the giant lizard, known as New Zealand's living fossils, is in danger of extinction. Studies have shown that rising temperatures have led to a significant increase in the proportion of males in large lizards, which may eventually become extinct due to the lack of females to reproduce.

3. Sea lily.

Sea lily is a kind of echinoderm that was first seen in the Carboniferous period, living in the sea, with multiple brachiopods, flower-like body, and calcareous shells on the surface. Sea lilies are ancient invertebrates that were found everywhere in the oceans hundreds of millions of years ago.

4. Monkey Tree.

Also known as the "Chilean pine", the monkey tree is an ancient coniferous tree. The tree has bizarre scaled (actually leafy) branches, and its bark is very distinctive, similar to that of reptiles. At the beginning of the 19th century, the monkey tree was first introduced to the United Kingdom, and by the 50s of the 19th century, this ancient tree began to settle in the botanical gardens.

5. Coelacanth.

The coelacanth is one of the oldest fish in the world and is often considered a living fossil. It was once thought to be extinct as early as 65 million years ago, but in 1938 it began to be discovered by humans, and since then coelacanth has been called "living fossils of the age of dinosaurs". Coelacanths are ferocious predators, with thick, mucusy bodies, limb-like fins, and agile movements.
