Latimai fish, alligator.

Cockroaches, baby fish.

Aardvarks, red pandas.

Giant lizards, mantis shrimps, elephant shrews. Living fossils are vaguely referred to as relict organisms, which refer to any organism whose analogous species exist only in fossils, and there are no other extant similar species.

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 that have a long origin, with a wide distribution 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.

As a result, some ancient creatures that lasted for tens of millions of years were formed, and other creatures of the same era have long been extinct, and only they have survived alone, adapted to the modern environment, and lived in an extremely small area, known as "living fossils".

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.

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. Large lizards.

The giant lizard is the only reptile that has survived the age of dinosaurs known on Earth, and its numbers have become 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, the 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.

Chinese tree species known as "living fossils" include: ginkgo, silver fir, dove tree, fragrant fruit tree, etc.

Animals that are known as "living fossils" in China include: giant pandas, "living fossils" in the water, Chinese sturgeon, etc.

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.

Chinese tree species known as living fossils include: ginkgo, metasequoia, dove tree, fragrant fruit tree, etc.;

Fungi known as living fossils: Trichophyllum granuloma;

Animals that are known as living fossils include: national treasure giant panda, Chinese sturgeon, Chinese alligator, etc.

Living fossils, vaguely referred to as relict organisms, refer to any organism whose analogues exist only in fossils, and there are no other extant analogues in the Rift Hall. These species once survived major extinction events and retain their original characteristics from the past. Some of the ancient species of organisms that exist are non-scientific terms.

The definition of a living fossil is generally the discovery of a fossil first and then a living body, or a living body that is of the same species as the fossil that is identified to be a fossil and exists at the same time.
