Do you know what the oldest animal in the world is?

The crossing between frilled sharks, sharks, and eels is disturbing. The frilled shark has survived for nearly 100 million years and is one of the top 10 living prehistoric animals. Luckily, it just hangs out near the bottom of the ocean.

The frill shark is a primitive shark and is the only species of shark in the genus Frillills of the family Frigills. Because of its extended gills and folds covering each other, it is called the frilled shark. ‍‍

Coelacanths are fishes of the order Coelacantha that contain the oldest submandibular phylum branches. The coelacanth species is thought to have been completely extinct at least 65 million years ago at the end of the Cretaceous period. This idea was only shattered in 1938 after the discovery of speartail fish in South Africa.

The two extant species of speartail fish are therefore also known as living fossils. Most people think that this 100-million-year-old fish is a long-term extinction. There was only one sighting reported in 1938 ......Until the last 10 years, when fishermen kept discovering them.

The oldest animal is the horseshoe crab, and these creepy little creatures are a common sight at many beaches across the country. They are the oldest animals and have lived for hundreds of millions of years. It's scary to look at. ‍

Lampreys, they use these terrible teeth to attach themselves to the fish to suck out blood. They have been living here for about 100 million years. has its own way of surviving and makes people feel scary.

The sturgeon is one of the largest freshwater fish in the world, but it is also one of the endangered animals. Two million years ago they would have lived and lived here, hoping that people would hunt them less because sturgeon were not a threat to people. ‍

The martialis heureka ant, the last ancestor of ants, this ant was produced 1.2 million years ago until it was discovered in the Amazon jungle in 2008. It is the last common ancestor of all ants found so far, and as the last ancestor of ants, it is also admirable that it has survived until now. ‍

A tadpole shrimp that doesn't look too scary, but it's been living for hundreds of millions of years? It is one of the top 10 living prehistoric animals. It's hard to think that this thing has survived to this point.

Tadpole shrimp, also known as three-eyed dinosaur shrimp, has actually experienced several radiation and extinction events. But they survived. ‍

A turtle can live for a long time, which is considered a very high-necked turtle. Galapagos tortoise.

The body length can reach meters, and the weight can reach 150 kg.

The Galapagos tortoise is arguably the largest tortoise in the world, with 14 subspecies spread across the surrounding islands, including the famous "Lonely George", who has since died. The Galapagos tortoise can be said to be a living fossil, a testimony to Darwin's theory of evolution.

Big nautilus. It has been around since the age of the oceans. It's been hundreds of millions of years old! If you don't believe me, you can go for it.

Pandas, pandas are also known as living fossils.

Ants, living in the same period as dinosaurs.

Odd shrimp, the overlord of the Cambrian seas 400 million years ago.

Cockroaches, there were cockroaches when there were no dinosaurs.

Cockroaches have existed since the Carboniferous Chronicle.

It has survived from about the Qing Dynasty to the present.

Ancient creatures are witnesses to the changing epochs of the natural world, and through one era after another, if they can communicate with humans, those scientists will know everything that is happening on Earth.

Aren't all cockroaches and crocodiles.

Nautilus, Jurassic shrimp to learn about.

Birds, because birds are the ancestors of dinosaurs.

Animals include tigers, wolves, rats, deer, martens, monkeys, tapirs, zebras, dogs, elephants, leopards, musk oxen, lions, red pandas, warthogs, antelopes, caribou, rhinoceros, lynxes, pangolins, giraffes, pandas, anteaters, orangutans, manatees, otters, civets, dolphins, walruses, platypus, hedgehogs, arctic foxes, koalas, polar bears, kangaroos, armadillos, hippos, seals, whales, ferrets, etc.

Animals: According to fossil research, the earliest chain-beam animals on Earth originated from the ocean. After a long geological period, early marine animals gradually evolved into various branches, enriching the early life forms on earth.

Prehistoric animals appeared before the advent of humans and flourished during their respective periods of quiet awakening. Later, they became extinct one after another in a constantly changing environment. However, the animals on Earth continue to evolve and reproduce from the lower to the higher, from the simple to the complex, and have the diversity they have today.

Ancient animals have: Cats, dogs, lions, tigers. Monkey. Wait a minute.

The peach blossom jellyfish, which was first born 100 million years ago, is still the most primitive and lowest-class invertebrate on the earth.

According to the existing biological fossils, the earliest animal is the trilobite population, and whether there is an earlier one is not really whether it will be found in the future!

The peach blossom jellyfish was first born 100 million years ago.

The most mysterious and magical "three-eyed dinosaur shrimp" is the oldest living animal on earth.

Coelacanths, the ancestors of vertebrates, appeared in front of 100 million people, and fossils exist from the end of the Permian to the end of the Jurassic period....Well, it was the first heroes to land, which still exists and is extremely rare.

The oldest animal is the sponge. It's a collection of simple cells, but it's able to eat, filter-feeding.

Sharks, sharks appeared as early as dinosaurs hundreds of millions of years ago.

In 1984, Mr. Hou Xianguang of the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences discovered the fossil of "Naro" in Maotian Mountain, revealing to mankind the early Cambrian world that had been sleeping for hundreds of millions of years, and it was no longer silent here. Entering the conch-shaped Maotianshan Institute of Paleontology, we feel as if we have traveled through time and space, and come to the ancient world where prehistoric creatures lived. The entire exhibition hall is decorated in blue, the curtain wall depicts the Cambrian ocean and ancient creatures of that time, and the glass array cabinet displays various paleontological fossils excavated in Maotian Mountain.

Looking through the magnifying glass on the array cabinet, we can clearly see the traces of these prehistoric lives, which make our imaginations swell rapidly. 1. Paleontology Research Station There is a building with a peculiar shape on the halfway of the Maotian Mountain in Chengjiang, which is the field workstation of the Nanjing Institute of Paleontology of the Chinese Academy of Sciences. Its design is inspired by the Cinderella insect, a Cambrian creature found on the Maotian Mountain.

The exhibition hall uses a variety of display methods such as sound, light, and electricity, making people feel as if they have entered the marine world, and the fossil bodies are lifelike, and under the gaze of people, these animals that existed hundreds of millions of years ago seem to be resurrected and displayed. 2.The world's earliest human ancestor fossil - Yunnan insect fossil In the Chengjiang animal fossil group, there is the world's oldest chordate - "Yunnan insect".

Yunnan insect is a scientific research fossil that shocked the world, according to scientists, Yunnan insect body length is about 3 5 cm, black, body movement by muscle contraction to make the body produce waves to swim. The blood circulation is an inner ring, and breathing is carried out by gills. Although its form is not pretty, it is the ancestor of all reptiles, mammals, the ancestor of humans, and the earliest "inhabitants" of the earth.

3.The Cambrian giant of the sea, known as the "Tyrannosaurus rex" of the ocean at that time, was 2 meters long and had two amazing claws, and whenever it swam in the ocean, other animals scattered for their lives. Don't underestimate its 2-meter length, in the marine environment at that time, it was able to support such a large animal, which shows the richness and diversity of flora and fauna.

From the point of view of time, it seems that it is not accurate to call the Tyrannosaurus rex "marine Tyrannosaurus rex", because it is 400 million years earlier than the time when the Tyrannosaurus rex appeared in the stage of life, so it should be more appropriate to call the Tyrannosaurus rex "terrestrial Tyrannosaurus rex". Interestingly, it took a whole century for people to learn about the odd shrimp.

The crocodile is the earliest and most primitive reptile found alive so far, it evolved from amphibians in the Mesozoic era from the Triassic to the Cretaceous (about 200 million years ago), and it is still a semi-aquatic ferocious reptile that continues to this day, it is a contemporaneous animal with the dinosaurs, and the extinction of the dinosaurs is a fossil regardless of the impact of the environment or its own reasons; The presence of a crocodile is a testament to the strength of its life.

The platypus is the oldest and most primitive mammal, appearing as early as 25 million years ago.

Tortoises and tortoises are groups of reptiles that evolved around their carapaces. Turtles were first seen in the early Triassic period, when they had fully developed carapaces. Early tortoises may not have been able to retract their heads and limbs into their shells as they do today.

Sharks have been on Earth since 300 million years before the appearance of dinosaurs, and they have been around for more than 400 million years, and they have barely changed in nearly 100 million years.

Horseshoe crab is a 300-million-year-old living fossil, horseshoe crab will shed its shell from the blood of horseshoe crab, extracted from the medical reagent, used to detect live bacteria and endotoxins secreted by bacteria, with high sensitivity.

Fairy shrimp The scientific name is "branchworm", this genus has lived on Earth for more than 200 million years, and is contemporaneous with the dinosaurs.

There are a lot of them, so let's just introduce them.

If it's an animal, it's upstairs. If it's a living thing, it's a bacterium.
