Dinosaurs are animals that disappeared centuries ago. Existed in the Mesozoic era. The term “dinosaur” first appeared in 1842. Translated as awful, awful. He was voiced by biologist Richard Owen. So he tried to show people their size and greatness.
Many scientists have tried to study these mysterious animals from the remains. But we managed to find out that among them were herbivores, carnivores and even omnivores. Many moved on two hind limbs, while others on four. Some walked calmly on two and four.
Since the discovery of dinosaurs in the world, they have been found on almost all continents. But it is worth saying that there were only a few of them on the territory of Russia. But, for example, in the Amur region there are several cemeteries of bones of these animals.
This article will look at the largest dinosaurs in the world.

Charonosaurus was first discovered on the Chinese bank of a river called the Amur in 1975. Excavations were carried out, as a result of which many bones and remains were found.
The clusters were at fairly large distances.
Among the individuals, there were young people and adults. Everything indicated that they had been killed by some sort of predator.
But it is also possible that they were eaten and then dismembered by various scavengers.
Charonosaurus was considered a fairly large dinosaur. The animal could move on its hind and fore limbs. The front ones were much smaller than the back ones.
Weight: up to 4 t
Iguanodon was the first herbivorous dinosaur discovered by scientists. In 1820 the bones were found in a quarry at Veitemans Green. Then, after some time, they dug up the teeth of the animal, which were intended for chewing plant food.
He could walk on all fours and on two legs. The skull was a little narrow, but wide. It is assumed that they died due to the cataclysms. The skeletons were found in one place. But nothing proves that they had a gregarious reflex. Perhaps they lived alone.

More edmontasaur has been found in North America. Presumably, they moved in small groups of 15 to 20 individuals.
Edmontasaurus is one of the largest herbivores. But they have a fairly massive tail, capable of lifting a passenger car into the air with one blow.
He ate standing on four legs, but only moved on two.
The only characteristic that distinguished this species from others was the structure of the skull. There was a platypus nose and a flat beak.
Weight: 12 tons
Dimensions: 15 meters
Shandugosaurus considered the largest representative of animals accustomed to eating plants.
Scientists discovered this species in 1973 in Shandong.
The structure of the skull was slightly elongated and rather wide. The front is slightly flattened and somewhat reminiscent of a duck’s beak.
They fed on the leaves of shrubs and young trees.
They lived in the forests of East Asia. It should be noted that they existed only in herds. Thus, they could fight enemies, and there were quite a few of them.
Weight: 5-7 tons
Dimensions: 13-14 months
Carcharodontosaurus considered a predator, but not the largest living in Africa. Translated from ancient Greek as “sharp-toothed lizard“. And indeed, it was so.
Quite strongly this species was distributed in North Africa, as well as in Egypt, Morocco. First discovered by French paleontologist Charles Depert. Then they found the remains of the skull, teeth, cervical vertebrae and tail.
The dinosaur had strong hind legs, which is why it moved only on them. To the detriment of the forelimbs, there are disputes. So scientists have not found out if they exist at all. But even if they were, they were most likely underdeveloped.
The skull was quite large. The jaw is relatively narrow, showing sharp teeth. The massive body ended in a large tail. They ate other animals.
Weight: 6-8 tons
Dimensions: 12-14 months
Stay for the first time giganosaurus were found in 1993 by hunter Ruben Carolini. It is a fairly large carnivorous dinosaur that lived in the Late Cretaceous period.
His femurs and tibiae are the same length, which means he wasn’t much of a runner. The skull is slightly elongated. Ridges can be seen on the nasal bones. This increased their strength during battles.
Studies that have been conducted only showed in 1999 in North Carolina. Here they tried to prove that the animal was warm-blooded and had a particular form of metabolism.
Weight: 4-9 tons
Dimensions: 12-17 months
Spinosaurus lived in what is now North Africa. One of the largest animals of this species. New finds constantly changed the idea of previous ones. Paleontologists have often been in conflict.
Many have noted that working on this species is like studying an alien. It bears no resemblance to any other previously identified creatures.
The dinosaur had a very thin neck, but a long, narrow snout, which helped it swallow fish whole. On the front of the skull there are peculiar recesses which helped to capture various movements in the water.
The teeth were very sharp and large. Perfect for catching fish. At the back you can see huge spikes 2 meters or more in height. It is not known exactly what they were intended for. Perhaps they helped in the thermoregulation of the skin of the body.
In 2018, scientists discovered that this particular species could swim easily, like many others. It was possible to turn over in the water on your side.
Sauroposeidon It is considered one of the largest types of dinosaurs. First discovered in the United States. Cervical vertebrae were first found in 1994 in a rural area not far from Texas.
The excavations were carried out by a team from the History Museum. The dinosaur had four cervical vertebrae. They were very long. Incredible height and his neck – about 9 meters.
Dimensions: 30 meters
argentinosaurus – one of the large animals that lived in South America. Existed in the Cretaceous period.
The only remains were found by scientists only in 1987 in Argentina. Found on the ranch of the owner, who at first mistook the bone for a simple fossil. But afterwards, giant vertebrae were dug out, which were about 159 centimeters in height.
This species was described in 1993 by one of the paleontologists named José Bonaparte. He introduced it as “Argentinian pangolin. For a long time, scientists could not determine the actual size.
It should be noted that documentaries and programs have been shot about almost all types of dinosaurs. Argentosaurus is no exception. The special issue “In the land of the giants” tells about the life and habitat of these species.
Dimensions: 48 meters
It is this genus that stands out among the others for its huge size. For the first time, animal remains have been found by Oramel Lucas in Colorado.
But they heard about it only in 1878. One of the paleontologists wrote an article about dinosaurs of the amphicelia species. That person was Edward Cope.
Land dinosaurs were large, which was not immediately proven by scientists. The intestines were used to digest low-calorie foods. Body temperature almost always remained stable, which cannot be said for smaller species.
