Elephants and giraffes are already behemoths in comparison to humans, but they are nothing more than rats meeting elephants compared to the behemoths that appeared on Earth hundreds of millions of years ago.

This issue of small science to bring you, the earth has ever appeared, the largest 8 kinds of giant beasts. If you are interested in this kind of article, move your fortune maker, give a little attention to the small science, your attention, is the driving force for the update of the small science.
▲NO.8 The largest mammal on land
The animal is called the giant rhinoceros, a mammal of the family Rhinoceros, and can weigh 15-20 tons.
Giant rhinoceros
Giant rhinos lived in the middle of the Tertiary Period in Eurasia, the Oligocene. But it was already extinct in the Miocene, and the giant rhinoceros family consisted of 12 genera, of which the Dzungar giant rhinoceros was the largest terrestrial mammal in history. Its body length can reach up to 12 meters, the highest can reach 9 meters, which is equivalent to three or four floors taller, and the weight is between 15-20 tons.
Adult giant rhinos and their cubs
In the Turpan Museum in Xinjiang, their fossils are the treasures of the town hall. The Tianshan deputy giant rhinoceros belongs to the same species as it, and the appearance of the giant rhino is somewhat similar to a mixture of giraffes and elephants, which should be somewhat related to rhinos. Because the giant rhino is particularly tall and the neck length is also very long, the giant rhino should mainly live in the woods. But judging by their teeth, they look like giraffes, so it is possible to live in arid and open areas, with leaves as their main food.
▲NO.7 The largest insect
Another name is the Big-tailed Dragonfly, an insect of the Carboniferous Period 300 million years ago, with wings spreading up to 75 centimeters, making it the largest insect species known to have ever appeared on Earth.
Big-tailed dragonfly
In appearance, it is still quite similar to modern dragonflies, and before the birth of dinosaurs, the giant veined dragonfly can be described as invincible in the air. It flew at a speed of more than 2 km/h, and during the Carboniferous period, the Giant Vein Dragonfly resembled a fighter jet in the air.
They feed mainly on insects and small amphibians, and they are more like eagles, about the length of a 6-foot-tall human arm. But only fossils of giant veined dragonflies that have not yet matured have survived, but they gradually went extinct in the Permian Period 250 million years ago.
▲NO.6 The largest flying creature
Pterodactyls are the air overlords of the dinosaur world, but you know what? Pterosaurs were not dinosaurs.
pterosaur
It is a flying reptile vertebrate that lived from the Late Triassic to Cretaceous periods, between 210 million and 65 million years ago. Similar to modern birds or bats, pterosaurs flew similarly to the Mulberry Pseudodont, mainly by gliding.
Among the pterosaurs, their size differences are also very large, from the smallest forest pterosaurs such as sparrows to the largest aeolian pterosaurs. They have a wingspan of more than 12 meters in length and have very sharp giant teeth, each about 10 centimeters long. If in a dream, a pterosaur happens to appear, it is definitely a very terrible nightmare.
Pterodactyls as they glide
In Romania in 2008, scientists discovered a new type of pterosaur cervical vertebrae fossil, many times larger than the previously found pterosaur fossil, which shows that in some ancient times there were still larger aerial giants waiting to be discovered by humans.
▲NO.5 The largest marine predatory reptile
Shanglong is a large marine predatory reptile whose main diet is some fish, squid and other marine reptiles. It is very good at swimming, evolved from the plesiosaur, and the dragon has been called a monster until it was officially named, which is enough to see how terrible they are in people's hearts.
On the dragon
The appearance of the dragon is like a mixture of a giant turtle and a super giant crocodile, and it is a monster like a submarine, and the place it passes is even more mournful. The head of the dragon was very large, but the neck was relatively short, the teeth in the mouth were as sharp as a machete, and the cross-cutting area of the muscles in the spinal cord was several times that of modern crocodiles.
Dragons prey on
The bite force of the upper dragon is even more amazing than 10 times that of the modern bay crocodile, the most famous in the upper dragon family is the slippery tooth dragon, but the largest body is the craterosaur, the craterosaur appeared in the early Cretaceous period, is a peak beast that developed to the extreme in the upper dragon family, the weight can reach 12 tons, the body length can reach 11 meters, and the head alone has more than 3 meters.
It can be imagined that a head as tall as a floor is a veritable Tyrannosaurus rex in the sea, and the specific time of extinction of the upper dragon is not clear, and it is speculated that it is probably in the late Jurassic period.
▲NO.4 The largest bird
25 million to 28 million years ago, after the extinction of the dinosaurs, in the period before the emergence of humans, there was a giant beast with feathers, its name was called the Mulberry Pseudo-toothed Bird.
Mulberry pseudolodon
The length of its wings can reach 7 meters, which is far more than the previous record holder, the Argentine Giant Eagle. It is also the largest modern flying bird, the Royal Albatross, with wingspan twice as long, and this type of bird may be the largest bird ever existed on Earth.
What concept? About the size of a fighter jet, the way they fly is mainly based on gliding, you can imagine it as a modern glider soaring several kilometers in the sky, without wings, and can fly for weeks, even months, without landing and resting.
The Mulberry Pseudomonitorn weighs only 48 pounds, and in the same way as modern birds, the bones of these birds are hollow. Judging from the tooth structure of the Pseudomonitorns, they mainly feed on some fish in the sea.
So when exactly did the Mulberry pseudolodon become extinct? And for what reasons for the extinction, it needs to be further investigated, and there is no accurate conclusion for the time being.
▲NO.3 The largest land predator
Spinosaurus lived probably from the Cretaceous Period, 112 million years ago to 93 million years ago.
Fossils of Spinosaurus are found mainly in North Africa and South America, and are most typically characterized by a large spiny back sail on its back. The height of this part alone is higher than that of humans. An adult spinosaurus can reach up to 15 meters in length and weigh up to 10 tons.
Spinosaurus
It is speculated through its anatomy and tooth features that this large carnivorous dinosaur fed primarily on fish, but may also have been a semi-aquatic dinosaur that lived in an area close to the seashore and rivers. And their feet have very large webs, which is also to make it easier for them to swim in the water, and the flat tail can also generate thrust in the water. But like most dinosaurs, it became completely extinct in the late Jurassic period.
▲NO.2 The largest mammal
This is very powerful, because it is the only one of the eight giant beasts that has survived to the present, and it is the blue whale.
blue whale
Not only is the blue whale the largest cetacean, it is also the largest living creature on Earth, and probably one of the largest and heaviest animals in the history of the ocean, with a pale blue or rat gray all over its body.
The body length of a blue whale can reach 33 meters, what is the concept? About the size of a Boeing 737, it can weigh up to 200 tons, equivalent to the weight of more than 30 African elephants combined. Blue whales are distributed worldwide, but their favorite place to live is the junction of warm and icy waters, where there is an abundance of plankton and krill, which are also the main food of whales.
At present, blue whales are mainly distributed near the north and south poles of the earth, but there are also a small number of whales that have come to the Yellow Sea and Taiwan waters, as the saying goes, a whale falls and everything is born, there is no need to say more about it.
▲NO.1 The largest giant beast
Fragile diplodocus, have you ever heard of this name?
He lived 140 million years ago and is closely related to Liang Long and Argentine Dragon. Fragile diplodocus may be the longest known and heaviest dinosaur in earth's history. The longest body length can reach an astonishing 58 meters, the height is about 15 meters, and the heaviest weight can reach 220 tons.
Fragile diplodocus
But the current human study of it is mainly in 1877, a fossil collector hired by paleontologist Edward Cope excavated and found part of the vertebrae of fragile diplodocus, but now the specimen has been lost, and no one has found a fossil similar to fragile diplodocus so far.
So some people think that the previous data is not so accurate, can not fully believe, as for the largest beast on the earth, which is it? At present, no one dares to jump to conclusions, because the dinosaur fossils found by humans are still very limited, and after hundreds of millions of years of crustal movement, the geographical location will also change, and in the unknown days in the future, larger dinosaur fossils may be found one day.
