In the thousands to millions of years before history, many huge creatures lurked on Earth at dawn until climate change — or early humans — accelerated their demise.
Prehistoric animals once roamed and dominated the earth.
Some of these, such as giant sloth or wool rhino, are generally mild. Other animals, such as saber-toothed tiger and terror , dominate their territory with their size and terrible fangs.
For millions of years, these ancient animals have walked on grasslands, climbed trees in the jungle, and kept chasing their prey. Despite the wide variation, they all become extinct in similar ways due to climate change, poaching or disease.
Today, their existence is just a whisper of their former power—a bone, a tooth—but at their heyday, these prehistoric animals would scare and awe early humans.
Cordion : Car-sized prehistoric armadillo
5.3 million to 11,700 years ago, a strange creature called Cordion walked on the earth. Cordion tits meant "titles with grooves".

This " giant armadillo " is ten feet long and weighs 4,000 pounds and is present in today's North and South America. Although the celestial beast has a powerful tail and an armored back of 1,000 bone plates, it may have lived a rather peaceful life. As a herbivores, it mainly eats grass and does not have to worry about any bloody battles.
That is, if needed, the celestial beast can protect itself—even against other celestial beasts. Its powerful tail can crush human skulls, while its shell-like back provides powerful defense.
Based on the damage found on the fossils of the carved beast shell, scientists believe that the beasts often fight each other. To resolve disputes between territory or spouses, they will pound their opponent's shells with their strong tails.
But this ancient animal also often has to fight against humans. Early hunters might have followed the celestial beast for its flesh and shell. To kill it, however, they have to turn it over and pierce its soft belly—it's not an easy task.
Early humans may have used the huge back of the celestial beast as a barrier
Researchers first discovered the celestial beast in 1823, when Uruguayan naturalist Dámaso Antonio Larrañaga discovered a huge femur . The bone weighs about seven pounds and is six to eight inches long.
At that time, most people thought he had found the bones of a giant sloth called giant sloth. However, further discoveries led scientists to believe that they were dealing with another prehistoric animal, which biologist Richard Irving calls a celestial beast because of its curved teeth.
Shortly after the last Ice Age, the rule of the celestial beast ended. Climate change and aggressive human hunting put giant armadillos on the verge of extinction.
Today, only their huge bones illustrate their existence. Just in 2020, an Argentine farmer found several carved beast shells in his yard.
Titan Python : The Ancient Snake
Imagine a giant snake 14 meters long and weighs 1.25 tons. This is what the terrifying Titan Python looks like.
This huge snake lived about 60 million years ago. After the dinosaur extinction of , it moved upward along the food chain and quickly dominated the tropical jungle of today's South America.
When its fierce eyes lock on the 5-foot giant turtle or 20-foot crocodile, the Titan Python is likely to wait for prey to approach in shallow water. Once the unfortunate animal is close enough, the snake will attack and crush its food to death.
Although this ancient animal has threatened the world for millions of years, it took modern humans a long time to realize its existence.
In 2002, a fossil leaf discovered in a Columbia coal mine led scientists to believe that the rainforest once thrived in the same location.Then they soon discovered fossils of giant turtles and crocodiles, as well as fossils of early bananas, avocados and legumes.
But among all the discoveries, there is one very prominent: a huge vertebrae. The researchers were convinced that it once belonged to a snake, possibly a snake trapped in a muddy landslide, so they searched the ground for more bones.

Finally, what they found was not one but the remains of 28 giant snakes. Excitingly, they also found three snake skulls.
As for those crocodile and turtle fossils? It may be the unfortunate victim of the giant snake. Scientists speculate that the Titan Python once ruled the animal kingdom.
American behemoth: giant ground laziness
Today's sloth is very small. But the ancient animals before them, called American giants, were veritable giants.
Fossils of the giant American behemoth
The American behemoth is nearly 4 meters tall and weighs more than 4 tons. It once roamed the jungles of South America. Unlike the sloths that live in trees today, American sloths walk on the earth. Fossils found in Argentina, Uruguay and Bolivia show that the beast lived between 400,000 and 8,000 years ago.
Although it may walk on four legs, the American behemoth can stretch to its maximum height to grab difficult-to-reach leaves. The organism has terrible claws, but chemical analysis of its teeth shows that American big mouth fish eats mainly leaves and plants.
However, like modern sloths, American sloths are calm. It moved slowly, probably slower than anything alive at the time. But its size provides ample protection, as these prehistoric animals weigh more than possible predators like saber-toothed tigers.

So, if American behemoth can find a lot of food and don’t have to worry too much about predators, then why did these prehistoric animals become extinct?
Scientists are not sure about the answer to this question. It may be due to climate events, or diseases, or the arrival of humans, as some American behemoths' bones appear to carry traces that match the hunting.
There is another view that the American behemoth may not have been extinct at all. People who hold this view believe that once humans arrive at the scene, the creature retreats into the depths of the jungle.
People living in the Amazon rainforest have indeed shared a story about a beast they call mapinguari. Mapinguari is said to be a slow-moving beast like a sloth standing on its hind legs.
crocodile : Prehistoric animal known as "terrifying crocodile"
terrifying crocodile skull
When it comes to prehistoric animals that look like modern monsters, it is probably difficult to bypass crocodile. In the late Cretaceous period, about 82 to 73 million years ago, the terrifying crocodile was more than 10 meters long and had teeth as big as bananas. Its name was literally translated as "terrible crocodile."
crocodiles mainly eat sea turtles and shellfish, but sometimes they are entangled with Tyrannosaurus Rex cousins such as Montgomery Appalachians and Albertas, and bite marks left on the fossils can prove this.
"The terror crocodile is a giant that must have frightened the dinosaurs who come to the water to drink water," explains Adam Cossett, a vertebrate paleontologist who studies the beast in New York Institute of Technology.
These terrible prehistoric animals live in today's America and Mexico. Their fossils were found in Utah , Montana , Wyoming , New Mexico , New Jersey , Georgia , Alabama, Mississippi , Texas and North Carolina.
However, this monster is indeed a bit different from modern crocodiles. In addition to its huge size, it also has a bulb-like nose with two vents. Scientists are not sure what crocodiles need vents to do, perhaps to help them cool down.
Like other prehistoric animals on this list, it took scientists a while to learn about the full picture of these ancient animals.The fossils of the terror were originally classified as another marine predator, the genus Polyptychodon, but in 1904, zoologist and paleontologist William Jacob Holland studied the existing evidence and concluded that the terror is a monster in itself.
Cave Bear: Ice Age Cave Bear
Ice Age Cave Bear (also known as Ursus spelaeus) is 3.4 meters tall and weighs 2,200 pounds, which must have caused fear in early humans.
But bears may not kill people - at least they won't eat people. Scientists believe that these prehistoric animals are mainly herbivores and feed on plants rather than humans.
In the late Pleistocene, these bears lived all over Europe. Tens of thousands of their fossils were found in caves throughout the continent, suggesting that they spend longer in caves than modern bears (usually only hibernating in caves).
However, they do seem to dare to take risks in dating people. Scientists are not sure how early humans interacted with bears, but they found some puzzling clues.
For example, in Drachenloch, , Switzerland, researchers found seven cave bear skulls that appear to be arranged in front of the cave, and six more stuck in cave niches.
However, this discovery pales in comparison to the nearly intact hole bear found by the 2020 reindeer hunters.
Hunter encountered this bear in the melting permafrost layer on the island of Bolshoy Lyakhovsky, Siberia. Probably between 39,500 and 22,000 years ago, the frozen tundra kept it in very good condition, and even its internal organs were well preserved.

So, what happened to these Ice Age cave bears? Although their cousins walk on Earth today, cave bears slowly faded from about 24,000 years ago. Scientists have noticed the high incidence in cave bear fossils, which may be a contributing factor; climate change could also lead to the extinction of Ice Age bears.
Gorgeous Lizard : The world's largest lizard
Today's Komodo dragon weighs up to 150 pounds, but their ancestor Megalania prisca (also known as Varanus priscus or giant lizard) can weigh up to 500 to 4,000 pounds. It is the largest lizard known to be on earth.
The Skeleton of the Giant Lizard
2 million to 40,000 years ago, these intimidating creatures easily ruled today's eastern Australia. They are up to 25 feet long and may feed on a wide variety of animals, including kangaroo , pygmy elephants and turtles.
Although they can use their size to uniform and kill prey, the giant lizards also use another tool: poisonous saliva. Scientists believe they use venom from the jaw gland to kill prey.
British naturalist Richard Irving first described the giant lizard in 1859. He named it the Giant Rover.
However, since Irving's discovery, scientists have discovered very few fossil remains of giant lizards. This means there is still much to know about this prehistoric animal.
The skull of the giant lizard
However, there are some theories about the reasons for the extinction of the giant lizard. Although humans do not seem to hunt it directly, they do hunt their food. Therefore, humans may have played an indirect role in their extinction.
Let’s talk about it again, just like giant sloths, some people think that giant lizards have never become extinct at all. There are rumors that the beast just sneaked into the Australian wilderness and has lived to this day.
Megalodon : Prehistoric animal with teeth as thick as human wrists
Megalodon's nickname is "Hell Pig".
These beasts have teeth as big as human wrists, and have cube-like bones on their faces. They can fight with each other or other animals, and divide their hooves.
During the Eocene, the hell pig spread rapidly from Mongolia to Europe and even to North America. Archaeologists have discovered fossils of the Megdoth in Nebraska, Wyoming, and South Dakota.
However, the Megdontus did not use its Megdontus to prey on other prehistoric animals all day long.Instead, it seems to use its huge chin to dig out the roots and chew the plants.
That is to say, hell pigs are likely to be omnivorous. Even if they didn't kill people with their own hands, they might have waited for other animals to kill them and then scared them away and eat their prey.
Hell Pigs may scare most animals in their surroundings, even if they don't kill them directly to eat. The bite marks they leave have been found in many animals, including prehistoric rhinos.
As the climate changes, the forest that the Hell Pig loves becomes a meadow. It is likely to lose to the faster moving animals due to being forced to travel long distances to find food.
In addition, during the existence of the Megdont, many new predators appeared on the horizon. They soon encountered terrible enemies such as saber-toothed cat and bear dog.
The last megaloman became extinct between 19 and 16 million years ago. Since then, these terrifying ancient animals have only existed in museums in fossils—or perhaps in hellish pigs, running through your nightmare.
Sabre-toothed tiger: Sharp Sabre-toothed tiger
Perhaps the most famous prehistoric animals on this list are Sabre-toothed tigers, or Sabre-toothed cats. Its eye-catching canine teeth make it look particularly scary.
Sabtoothed tiger lived between 2.5 million and 11,700 years ago, living in the forests of North and South America. Their size varies by type. Some can grow to about 150 pounds, some can grow to 200 pounds, and some can weigh about 500 pounds.
However, a recently discovered saber-toothed tiger population fossil suggests that saber-toothed tigers may be much larger. Depending on the size of its head, scientists think it could grow to 1,000 pounds.
Regardless of body size, these large cats have one common feature: canine teeth. These sharp fangs are located on one side of the chin and hang threatily on both sides of the cat's face. In order to stab the prey, the saber-toothed tiger must have its mouth opened above 90 degrees.
Surprisingly, big cats have fragile teeth. They sometimes lose their teeth in battle. Therefore, saber-toothed tigers often prey on trees. They jumped off the branches and made a sudden attack, biting the unsuspecting animal below with their teeth.
Nevertheless, they are still terrible killers. Sabertoothed tigers may prey on bison, sloth, mammoth, horse, pig and llama . In other words, they kill everything they can kill.
Sometimes, the pursuit of prey is deadly for saber-toothed tigers. Thousands of saber-toothed cat bones were extracted from La Brea tar pit in CA .
The ever-changing climate and the consequent scarcity of prey may bring an end to these terrifying and majestic ancient animals.
Dire Wolf: Prehistoric Animals depicted in " Game of Thrones "
In the TV series "Game of Thrones", many characters have a terrifying wolf companion. These wolves are often huge, fierce and loyal. Game of Thrones may have some imaginary elements, but the dire wolf is a real ancient animal.
The real dir wolves—known as Canis dirus, or “terrible dogs”—have existed about 125,000 to 10,000 years ago in today’s North and South America. Although similar to gray wolf , dire wolf is genetically different.
The dire wolf is slightly larger than the gray wolf, with red fur, weighs about 130 pounds and is about 6 feet long. Just like the dire wolf in the novel, dire wolf has powerful jaws to help them kill.
Divine wolf chases all kinds of prey. They hunt horses, bisons, and even young mammoths. By rushing toward the prey and biting it with your chin, the dire wolf drags the animals to the ground to kill them. Therefore, their fossils are often found to have neck injuries.
Sometimes, they actually compete with saber-toothed tigers for prey.
Gig Ape : The largest Ape ever
Maybeans do not exist, but there have indeed been equally huge beasts on Earth - prehistoric giant apes can compete with Big Foot.
However, like Bigfoot, prehistoric giant ape is elusive.Scientists have found little fossils of their fossils, and most of them have fragments of teeth and gorilla jaws. Even so, however, the researchers have come to some amazing conclusions.
They believe that the prehistoric giant ape is about 10 feet tall and weighs close to 600 pounds. Prehistoric Gigapons may be the ancestor of today's orangutans, and it lived in Southeast Asia for about 6 to 9 million years before it became extinct about 100,000 years ago.
Based on its teeth—nearly 2,000 large molars, canines and other teeth have been found—the researchers suspect that prehistoric giant apes are vegetarian. These ancient animals may eat plants, fruits, seeds, and may even eat bamboo .
Although scientists have found few fossils, they have discovered many ape jaws and teeth
However, the diet of prehistoric giant apes may have been doomed to its extinction. Although most prehistoric animals were foraging in forests and grasslands at that time, apes were stuck in the forest.
As the forest shrinks, their food supply also decreases, and the giant apes become extinct.
In fact, it was not until 1935 that modern humans felt the existence of prehistoric giant apes: a German paleontologist named Gustav von Konigswald stumbled upon the teeth of some apes in China. They are sold in the form of "dragon teeth", suggesting to many scientists that humans once had a huge ancestor.
Wooled rhino: Furry prehistoric animal wandering Eurasia html
Everyone has heard of mammoths. But what about the wool rhino?
In some ways, the woolly rhino (Coelodonta antiquitatis) looks a lot like the rhino today. Like rhinos of their time, they stand about 6 feet tall and weigh about 3 tons. They also have a group of two corners, a large front corner and a small one between the eyes.
But wool rhino differs in several important aspects. On the one hand, their heads and bodies are longer and their legs are shorter. There is also a large hump behind the shoulders of the wool rhinoceros, which may help support their horns. They have furs – and a lot.
Before it became extinct about 14,000 years ago, the woolly rhino wandered around. Its fossils have been found in Spain, Siberia and South Korea. Therefore, woolly rhinos sometimes appear in ancient cave paintings—although not as frequent as woolly mammoths or bisons.
Humans and wool rhino may have limited interaction, although there is evidence that humans sometimes hunt this prehistoric beast. That is, scientists believe that climate change is the main cause of the extinction of woolly rhinos.
But if climate change thousands of years ago killed the woolly rhino, today's climate change could bring it back. Serbian The melted permafrost reveals many well-preserved Ice Age creatures, including woolly rhinos, that reappear in another form.
2020, locals in eastern Siberia accidentally found a frozen corpse of a young woolly rhinoceros in the melting ice. The frozen land preserves the ancient animal's intestines, fur, and even its horns.
