What paleontists were real but now extinct?

Many people say that long-haired mammoths do not exist. In fact, mammoths were real in ancient times, and recently scientists have discovered the DNA of mammoths and extracted them.

First, trilobites, the very famous Cambrian creatures, second, giant dragonflies, lived in the Devonian jungles, and third, Tyrannosaurus rex, the most powerful carnivore ever seen on Earth's land, these real paleontology have long since become extinct.

Many ancient creatures were real and became extinct over time, the most well-known of which is the dinosaur family, which became extinct due to changes in the earth's environment; There are also platypus, reptile mammals, which are also extinct; There are also Hawaiian crows, which are also unable to survive because of the harsh living environment; The Wymin Russian toad is a very unpopular small species, but it is indeed one of the species that exists and becomes extinct.

Real but extinct creatures include the Spix macaw, the South China tiger, the mammoth, the North African white rhinoceros in Africa, and the Knott's leaf finch in South America.

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 once lived at the bottom of the world, and this creature is huge, 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 an absolute advantage of its own.

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, during their flourishing period, the body length can reach six meters, as long as it is the prey targeted by the nautilus, none of them can escape.

Carboniferous giant horses, ground sloths, sharp-toothed shield fish (Dun's fish), megalodon, hacking birds, brutal lions, short-faced bears, titan pythons, emperor crocodiles, dragons, and many more.

Most of the above lists are ancient extinct creatures with large bodies and brutal temperaments, and if you only say "terrible", I recommend almost all the creatures of the Carboniferous period, thank you.

Thankfully, a terrible creature that has been extinct.

Some of the paleontology is extinct, and some are still alive today, why is that?

Whether the paleontology is extinct or extinct to this day depends on whether it can adapt to the changes in the environment and the pressure of survival. Some paleontology has had some advantages in the past, and can better adapt to the environment and resource allocation at that time, so as to survive the long evolutionary process and become modern species. Some paleontology are gradually becoming extinct due to environmental changes, lack of food, failure to compete or natural predators.

For those paleontologists that still exist, they often have certain adaptability and survival advantages, such as having a body structure that adapts to a specific environment, feeding habits, reproduction methods, and so on. These advantages allow them to compete better and reproduce in a stressful environment to maintain the population. In short, the survival of paleontology depends on its ability to adapt to environmental changes and maintain an advantageous position in the competition for survival.

Over the course of the Earth's long evolution, a total of five mass extinctions have been identified. In other words, there were six generations of overlords on the earth, and because of the five mass extinctions, the first five generations of overlords have withdrawn from the stage of history. The mass extinction here does not mean the extinction of one species, but the extinction of all species of entire families, orders, and classes.

For example, the Fifth Mass Extinction.

time, Cretaceous.

The end of the dinosaur mass extinction.

The entire order Dinosaurs were extinct, and of course many other creatures were also extinct during the same period.

Let's take a closer look at the five mass extinctions.

The first mass extinction – the Ordovician mass extinction. Ordovician life is still inseparable from seawater, at this time, marine invertebrate species flourished, becoming the "first generation of overlords" on the earth, Ordovician was in the Great Ice Age, the temperature changes drastically made 85% of the earth's life extinct.

The Second Mass Extinction – Devonian.

Mass extinction. During the Devonian period, amphibians began to appear on Earth.

and vertebrates, but the largest number is the "second generation overlord" - fish. During this period, there was a magma eruption 30 billion cubic meters in front of it, the effects of which lasted for 2 million years, and nearly 65% of the life was extinct.

The third mass extinction - the Permian mass extinction. The main views of scientists in this mass extinction are the theory of continental drift and natural disasters.

It is said that during this period, the activity of the continental plates was relatively active, and the movement between the plates was relatively intensified, which led to the eruption of ** mountains and **, which led to the third mass extinction.

The fourth mass extinction, the Triassic mass extinction, was the mass extinction 200 million years ago. The overlords of the earth in the Triassic were reptiles.

Archaeologists have analyzed the rock layers where the fossils of the creatures at the end of the Triassic period are located, and found that the humidity of the rock formations in this period was much higher than that of other periods, so scientists speculate that heavy rains were frequent during this period, and this heavy rain, which may have lasted for 1 million years, led to a large lack of oxygen and extinction of organisms. A total of 76% of all living things have disappeared from the face of the earth.

The Fifth Mass Extinction.

Cretaceous dinosaur mass extinction. The mainstream theory given by extinction scholars is that it is related to the impact of meteorites on the earth, which caused sunlight to reach the earth's surface, and many organisms died out in hunger and cold.

In fact, there are still many prehistoric creatures that have survived, such as lampreys.

The appearance time of lampill can be traced back to 30 million years ago, belonging to the class Rotunda and the order Lampreys. The ancestors of horseshoe crabs first appeared in the Devonian period, that is, during the Second Mass Extinction, but they are still alive and have high medicinal value.

Because of bacterial infections and changes in the ecological environment, the extinction of organisms has been caused, and a lot of remains have been left behind.

It was extinct because of the weather, and the weather was very cold at that time, and many plants and animals froze to death.

Because of the impact of the ecological environment and the pollution of the social environment, it eventually leads to the extinction of organisms, which is related to the factors of social development.

1. Long-necked dragon, this reptile is 20 feet long, but has a 10-foot neck! Evidence suggests that this is a fish-eating reptile because its fossils are found mainly in some aquatic fossil sites, where fish scales and cephalopod tentacles are found in their stomachs.

2. Shalovsaurus, a gliding reptile with two "wings" on its hind legs and two small "wings" on its front legs. Some scientists believe it is related to plesiosaurs, but it is doubtful that it turned its wings upside down to its legs instead of its arms.

3. Dicosaurus, by far this fossil is by far the strangest. It is 5 feet tall, or an estimated foot tall if the entire fossil is intact. They range in length from 131 feet to 196 feet, which makes it the longest shouting brigade creature to date, however, the fossils are gone, misunderstanding?

Or is it really the biggest animal in the world? Sadly, we may never know.

4. Thoracic spine sharks, sharks have lived for over 400 million years, and while they have remained relatively unchanged throughout the fossil record, there are certainly some strange features, with an anvil-like dorsal fin with small spines that can be used for courtship or defense.

5. Dinosaurs, the only fossil of this dinosaur is a pair of arms, which look like they belong to avian animals, but they are 8 feet long. Its claw use is controversial: some say it was used to shred large dinosaurs, others say the claws were too blunt, so they were used as defensive **.

Some even say that dinosaurs used their giant arms to climb trees, although few agree with this hypothesis.

6. Phonosam, this type of elephant is not only large, but also has a pair of jaws with long tusks. These strange tusks may have been used to dig up soil for roots and vegetables, and they also have relatively short torsos, with their height ranging from 12-15 feet, making them one of the largest mammals ever to walk on the planet.

7. Yaolong, this bird-like dinosaur reveals an interesting part of the bird's evolutionary history, there are no flight feathers, but it does have four long-tail feathers, which are likely to be used for display. It lived about 152 to 100 million years ago, and it was also one of the smallest dinosaurs, standing only 10 inches tall when it reached adulthood.

8. Scythe, this strange and mysterious theropod is known for its long neck and huge claws, Hyoming they are herbivores, some of them may have feathers, and its claws are large, most likely up to a meter long.

9. Nightpterosaurus, the only one without claws on its wings, this species had a huge antler-like peak that some speculate could be used like a sail to enhance its ability to fly. However, studies have shown that such a large peak can actually affect its flight, so it is likely that it just has a strange set of horns.

10. The Dunkle's fish, this Devonian fish is one of the most feared creatures that ever lived in the ocean, it can grow up to 33 feet long, has an armored face, and is likely to be one of the most intense animal bites in history.
