Which species are making you sigh about the extinction?

It's the Yunnan closed-shell turtle, this turtle is really good-looking, but then it became extinct, I think it's a pity, if this turtle is still there, I will definitely raise it.

Dinosaur. Their extinction has become an unsolved mystery, and no one knows what happened thousands of years ago, so I think it's a pity that they went extinction.

It is a mystery how many animals there are in the world. Know that new species are discovered every year today. Of course, a large number of animals disappear or even become extinct every year!

The words of the Eight Classics are Bering manatees. Less than 300 years ago, the waters around Bering Island were home to a rare species of giant manatee, known as the Bering Manatee, also known as the Steylor Manatee. Just 27 years after its scientific discovery by Europeans, the Bering manatee, a giant beast with a body length of more than 8 meters and a weight of up to 10 tons, has disappeared from the face of the earth forever.

The small-toothed civet, a smaller civet of the family of civets, is only found in Mengla and Mengyang in Xishuangbanna, southern Yunnan, in China. Extinct in the eighties of the last century. The sickle-winged fowl, a typical forest bird, generally inhabits the altitude range of 700-1600 meters.

In China, mainly in the lower reaches of the Heilongjiang River in the northeast and on the northeast side of the Xiaoxing'an Mountains, the wild sickle-winged chicken was declared extinct in 2001. Once widely distributed in the southern provinces of China, the Chinese rhinoceros inhabits the forested mountainous areas close to water sources. It was hunted down for its important medicinal properties and completely disappeared from China in 1922. ‍‍

The dodo is said to be very large, fat, and can't run, so it's very cute. But the dodo was extinct because people hunted it, and I really regret not being able to see it with my own eyes.

The dodo, the national bird of Mauritius. When the Dutch came here, after a long voyage, they were very hungry, and they saw that there was a big bird on this island, which was particularly fat, and the ordinary one had ten pounds, and was not afraid of people. This bird was eaten out later.

In fact, this bird is not delicious at all, and the meat is small and delicious. But it's better to grasp, and the ecology has also been destroyed by these Westerners, and in the end there is no one, and now only the skeleton can be found, and the skeleton can still be sold for four million.

Of course, it is the high-nosed antelope, which was originally distributed in southern Russia, Mongolia and northern Xinjiang of China, because the antelope horn is a precious medicinal material, it has been hunted in large quantities for a long time, and the wild population in China has been extinct in the 60s of the 20th century.

Distributed in Bangladesh, Bhutan, Cambodia, India, Nepal, Pakistan and China, due to habitat destruction, the population is extremely small, and the guinea deer in China became extinct in the 70s of the 20th century.

Baiji dolphins, we watched them go extinct, is there anything more suffocating than this?

I think the most regrettable thing is the Lop Nur tiger, a tiger population that has become extinct in Xinjiang and was recognized as extinct in 1979. ‍‍

In fact, China was once the homeland of rhinoceros, and during the Ming Dynasty, there were still wild rhinos in China, and because this rhinoceros horn was said to be used in medicine and then ......

The Arctic penguin, the Chinese rhinoceros, the coming extinction of the northern white rhino, the wild extinction of the South China tiger ......

In fact, I feel very distressed about the extinction of any species, and I hope that the human species will kill other life on the earth, and any species has a reason for its existence.

The passenger pigeon, from 100 million kills to extinction, is scary to think about.

Tyrannosaurus rex, since I was a child, I have always wanted to see what a real Tyrannosaurus rex looks like. But I'm afraid it will eat me.

Tasmanian Tigers! That is, thylacine!

Dodo, North American passenger pigeon, great dugong, etc.

It is not a pity that any species is extinct, and when it is extinct, new species will be born, such as viruses.

Birds! I really wanted to meet this amazing animal, but unfortunately it never will.

The baiji dolphin is so beautiful, it was once so close!!

Ice Age animals, you can see them at the zoo with a little effort.

Dinosaurs, dodos, thylacines, megalodons.

<>1. There are generally two reasons for species extinction, one is natural and the other is man-made;

2. Natural causes: In the long course of history, some organisms will adapt to the environment and gradually evolve, while others will not adapt to the environment, and the number will decrease and even become extinct, which is the result of natural selection, many species are now extinct, and new species are constantly being produced at the same time;

3. Man-made causes: man-made destruction of the environment, human activities have destroyed the living environment of other organisms. There is also the fact that humans hunt other species for a variety of different reasons, causing species extinction.

The reckless introduction of new species from the outside world without sufficient consideration can sometimes greatly threaten native species, leading to the extinction of some species.

The top 10 extinct terrible paleontists are: the upper dragon, the dinosaur, the whirltooth shark, the giant ape, the Mamenxi dragon, the Goth's bird, the titan python, the ancient centipede insect, the giant feather-winged horseshoe crab, and the straight-shelled nautilus.

1. Shanglong: The dragon used to live at the bottom of the world, and this creature is very large, reaching an incredible length of 15 meters, and its head alone has reached 2 meters. In addition to its sheer size, the dragon also has incredible speed and great strength, which allows it to hunt with ease.

2. Moa: The moa lived in New Zealand 1,500 years ago, and this bird could not fly because of the cruel killing of humans, and the moa has completely disappeared. The moa is very tall, about three or four meters, which is its absolute advantage.

3. Spiral Tooth Shark:The whirltooth shark, very similar to modern sharks, lived 300 million years ago, and its teeth were very sharp and sharp, and often fought with fish of its size. Their teeth are arranged in a way that looks like a circular saw because of the low jaw position, which is a surprising feature.

4. Giant ape:The giant ape, which is said to be the prototype of King Kong. Historically, great apes were the most muscular apes in history, and their appearance was similar to that of modern apes, but they were taller than modern apes, about 3 meters.

5, Mamen Creek Dragon: Mamenxisaurus was a herbivorous dinosaur that lived hundreds of millions of years ago. It is worth mentioning that Mamenxi Dragon has the longest neck in the world, about 14 meters long, which is equivalent to half the body length.

Mamenxisaurus is one of the largest sauropods ever discovered in China.

6. Goth's birdThe Gordon Bird, also known as the "Gaston Bird", is terrifying about its large beak that looks like it can knock you to the ground in minutes. And the appearance of Goth's bird gray is also extremely frightening.

7, Titan Monty Python:The titan python lives on the Guajira Peninsula in South America. It is 15 meters long and weighs more than 1,000 kilograms, and you can feel the horror of the Titan Python just by listening to the numbers.

Thankfully, they died out 58 million years ago.

8. Ancient centipede insects:Ancient centipedes were the first invertebrates to appear on land, and their appearance was similar to that of centipedes today. The ancient centipede was very long, about 3 meters long, and lived by eating smaller animals.

9. Giant feather-winged horseshoe crab: The giant feather-winged horseshoe crab is shaped like a giant toy and lived hundreds of millions of years ago. It was the first creature to migrate from water to land and also did not learn to shed its husk.

They can parade very freely underwater, but when they reach the ground, they are extremely bulky.

10. Straight-shell nautilus:The straight-shelled nautilus is one of the terrible creatures that have gone extinct. It lived in the late Ordovician to the Cambrian period, the late Ordovician was a top food predator, in their flourishing period, the body length can reach six meters, as long as it is the prey targeted by the straight-shelled nautilus, none of them can escape.

a) Ordovician mass extinctions.

At the end of the Ordovician period, about 100 million years ago, the Earth entered the Andean-Saharan Ice Age due to global climate cooling. Sea levels had dropped dramatically, and a large number of marine life had died out, with about 85% of species going extinct at that time.

2) Devonian mass extinctions.

Between the Late Devonian and Early Carboniferous, about 100 million years ago, it is understood that the Central Pacific Ocean emitted a large amount of volcanic ash and greenhouse gases, causing sea level decline and climate change, and marine life suffered another catastrophe, and about 82% of marine species became extinct.

iii) Permian mass extinctions.

About 100 million years ago, when about 96% of all species on Earth went extinct, it was the worst mass extinction. Scientists believe that the mass extinction was caused by a series of causes such as climate warming, desert expansion, volcanic eruptions, and rising sea levels.

iv) Triassic mass extinctions.

About 200 million years ago, in the late Triassic period, sea levels rose, resulting in the emergence of large areas of oxygen-deficient seawater. About 76% of species are extinct, reptiles have been devastated, and many marine life has disappeared.

v) Cretaceous mass extinctions.

65 million years ago, at the end of the Cretaceous period, the mass extinction was the second largest in the history of the earth, about 75%-80% of the species extinction, announcing the disappearance of the dinosaurs that had ruled the earth for a long time since the Jurassic.
