The slowest dinosaur. The largest dinosaurs known to science. The smartest dinosaurs

13-18 meters

The largest terrestrial predatory dinosaur that lived on the planet 112 million years ago. Spinosaurus is not only the largest, but also the most dangerous land predator, which managed to spread terror mainly in the territory of the current North Africa. According to available data, two skeletons dangerous creature were also found in Egypt and Morocco. Based on archaeological finds, its back was covered with long spikes, exceeding the diameter of the vertebrae by about 10 times. The length varies from 1.5 to 1.7 meters. Most likely, the spikes allowed the "predator" to regulate body temperature. Thus, the largest carnivorous dinosaur is not a Tyrannosaurus Rex at all. Modern paleontologists are sure that with the help of their "sails" spinosaurs scared away other predators. Although, based on the dimensions, this creature had no enemies on land. The weight of representatives of the spinosaurid family ranged from 7 to 21 tons with growth up to 4.5 meters.

The name for the representatives of this family of dinosaurs was invented by Savage in 1873 after the discovery of a small number of remains of the creature - 3 teeth of 7 centimeters. Later it turned out that the paleontologist managed to find the remains of the largest marine dinosaur- Liopleurodon. It is known that the reptile also lived in the territory of the current Germany and England. The viviparous species had first-class protection - very strong bone plates under the skin. The maximum length of teeth found during the entire existence of the planet is 30 centimeters. Most likely, the largest representative of the genus reached 20 meters in length.

It's about about the biggest water dinosaur, which is also the most large predator. Luckily for other animals of the time, Pliosaurus never left the water. For a long time, experts believed that the maximum length of the predator reached a maximum of 20 meters. Everything changed after the discovery of paleontologists in Mexico - an eighteen-meter skeleton, on which there were traces of four-meter teeth of another predator. Consequently, the dimensions of the second Pliosaurus ranged from 25 meters. Only flippers, according to rough estimates, were 3 meters.

Among the biggest herbivorous dinosaurs experts attribute Puertasaurus, whose length reached 120 feet. In 2016, a certain Matt Wedel spent comparative analysis vertebrae of Puertasaurus with Notocolossus, as a result of which he found out that the weight of a plant-eating animal could reach 80 tons. Before this scientific work it was believed that the maximum weight of the creature is 50 tons. Thus, we see that the study of dinosaurs is very relevant. It is possible that in a few years we will learn completely new data and important facts about the life of dinosaurs.

Now you know how much the largest dinosaur in the world weighed! Share your comments, and don't forget to stay tuned for new content!

Did you love dinosaurs when you were just a kid? Many children were fond of cartoons about these ancient and majestic creatures, and someone even collected toy monsters and voraciously read entire encyclopedias dedicated to the description of dinosaurs.

In the old days, our planet was inhabited by the most incredible animals. Some of them were small modern birds, while others grew into real giants, which no one had seen for a long time. In this list, you will meet the true giants of prehistoric times.

25. Cotylorhynchus

It was the largest Pelycosaurus and at the same time the ancestor of modern turtles. The creation weighed about 2 tons!

24. Moschops

Moschops from the order of therapsids were a kind of cows of the Permian period. Approximately 225 million years ago, these harmless giants grazed in the fields and weighed a ton. Moschops were supposedly the ancestors of some modern mammals, and they lived mainly on the African plains, gathering in large herds.

23. Smoke

Smoke was an archosaur of the Triassic period. This ancient predator was the ancestor of dinosaurs more familiar to us and weighed over 1000 kilograms.

22. Mosasaurus

This creature grew over 15 meters in length and weighed more than 15 tons. Mosasaurs were the last most formidable aquatic predators before prehistoric sharks replaced them.

21. Elasmosaurus

Elasmosaurus weighed 3 tons, and in length from the tip of the tail to the nose, it grew by about 13.7 meters. Despite its impressive size, it was an underwater predator that preferred to hunt mainly small fish and cephalopods.

20. Liopleurodon

The name of this genus translates roughly as "teeth with smooth sides". The water creature weighed about 7 tons and ate not only fish, but also quite large marine reptiles.

19. Kronosaurus

Kronosaurus was the largest member of the pliosaurus family, and it got its name in honor of the Greek god Kronos, who ate his own children. This prehistoric was the main aquatic predator of its time, and it literally ate everything in its path. Like liopleurodons, kronosaurs weighed about 7 tons.

18. Shastasaurus

It was the largest genus of ichthyosaurs. The giant dolphin-like beast lived in the oceans of the Upper Triassic period and weighed as much as 75 tons!

17. Sarcosuchus


Photo: HombreDHojalata

Also known as the "Supercrocodile", this imposing creature grew up to 12 meters in length and weighed over 15 tons. It turns out that it was 2 times longer and 10 times heavier than modern crocodiles!

16. Quetzalcoatl


Photo: Alina Zienowicz (Ala z)

When it comes to pterosaurs, it's not the weight that matters, but the wingspan of these ancient creatures. Quetzalcoatl was the largest representative of his detachment, and his wingspan reached an impressive 10.6 meters. It was practically the size of a small plane, a plane with claws and a predatory beak!

15. Riohasaurus

This 9 meter and 10 ton herbivore lived in South America about 200 million years ago. He moved very slowly, and unlike other sauropodomorphs, he could not stand on his hind legs.

14. Diplodocus (or dvudum)


Photo: Dmitry Bogdanov

Scientists believe that diplodocus were the longest dinosaurs in the history of the Earth. Their sheer size was probably a major deterrent, making the double-thinkers afraid of almost no predators. All diplodocus were herbivores and grew up to 54 meters in length, while gaining a weight of about 113 tons!

13. Brontosaurus

Brontosaurus for a long time confused with Apatosaurus, but recently scientists have found that it was still a whole separate species of prehistoric creatures. From him close relative the giant can be distinguished by a longer and thinner neck.

12. Deinocheirus


Photo: FunkMonk (Michael B. H.)

This creepy creature was related to ornithomim and weighed about 6 tons. Disputes over the classification of the animal have been going on for a long time, because this one very much resembled the ancient ostrich-like dinosaurs, but in the end they decided to classify it as a theropod. The dinosaur's name translates roughly as "terrifying hand" (due to its huge claws), but with these terrible paws, the beast only tore grass.

11 Gigantoraptor

The name of this dinosaur speaks for itself. Gigantoraptors were the largest oviraptorosaurian theropods. In fact, it was a huge bird. Surprisingly, scientists still cannot understand whether this dinosaur was carnivorous or preferred vegetable food. Maybe he even ate everything.

10. Magnapaulia

Magnapaulia were the largest gaurosaurids. For the similarity of the muzzle of these creatures with duck heads, they are sometimes also called duck dinosaurs. The 15-meter and 25-ton creature lived in North America, and, despite its impressive size, it was able to run on its hind legs, and did it quite quickly.

9. Titanoceratops


Photo: Nobu Tamura

This species is cladistically related to Triceratops, but it appeared on Earth several million years earlier than its own. famous relative. The name itself says a lot - it was truly a gigantic beast! Titanoceratops grew up to 9 meters in height and weighed about 6.5 tons.

8 Utahraptor

In Jurassic Park, velociraptors were given enough attention, and they were the size of a chicken. Utahraptor, on the other hand, is a much more impressive beast, because it grew up to 6 meters in length and weighed almost 700 kilograms.

7. Tyrannosaurus

It was one of the largest carnivores ever to have lived on Earth. Most large tyrannosaurs grew up to 12 meters in length and weighed almost 9.5 tons.

6 Gigantosaurus


Photo: Durbed

It is not surprising that a creature with such a name got into our rating. In appearance, it was almost the same tyrannosaurus, but still larger. In addition, Giganotosaurs lived 30 million years earlier than T-Rex.

5 Spinosaurus

Many mistakenly believe that it was the tyrannosaurus rex that was the largest carnivorous animal in the history of our planet. However, the spinosaurus (the very first swimming dinosaur in the world with a crocodile's mouth) weighed as much as 10 tons more than the legendary tyrannosaurus rex.

4. Amphicelium


Photo: DiBgd

This huge dinosaur has long been considered the largest animal on Earth. The most massive bones indicate that these creatures grew up to 58 meters in length and weighed up to 122 tons. Unfortunately, the remains of such a large amphicelium were lost in the 1870s, and only records remain about them. Recent studies have shown that errors may have been made in older documents, but we will never know for sure ...

3 Bruhatkyosaurus


Photo: Goombasaurusrex

This dinosaur was first discovered in India. The found prehistoric creature has every chance of being the largest animal in the world. It remains only to unearth its complete skeleton, if the archaeologists are very lucky. Analysis of the available remains suggests that this one grew up to 46 meters in length and weighed about 200 tons! However, so far, scientists have only a few bones at their disposal, so they cannot say with complete certainty that Bruhatkayosaurs existed at all. The discovered remains may even belong to a completely different species.

2. Futalognkosaurus


Photo: Nobu Tamura (http://spinops.blogspot.com)

Bones of this species were found in Patagonia, and experts believe that it grew up to 30 meters in length, and the weight of the giant could reach an impressive 50 tons. The most prominent features of futalognkosaurus are the incredibly wide hips (3 meters).

1 Argentinosaurus


Photo: Dinosaur Zoo

You may have already guessed that this giant titanosaur was named after the country where it was found. An assessment of the discovered fragments suggests that the creature grew up to 36.5 meters in length and weighed almost 100 tons. Just one vertebra of this dinosaur is 159 centimeters long!

The smallest

1st Place: Microraptor

With feathers and four primitive wings (one on each limb), an early microraptor Cretaceous resembled a parrot, but with extremely strange mutations. Nevertheless, it was a real raptor, although in size it was only about 60 centimeters from head to tail, and weighed several kilograms. Considering the microraptor's weight, paleontologists believe that it fed on insects.

Runner-up: Lariosaurus

Photo: Carnegie Museum of Natural History/Wikipedia

Lariosaurus lived in the seas, but was only about 60 centimeters in size and weighed about nine kilograms. It is one of the smallest marine reptiles discovered to date. The lariosaurs died out at the end of the Triassic period, and were replaced by larger and more ferocious pliosaurs and plesiosaurs.

Third Place: Microceratops

Microceratops, also known as microceratops, is the smallest member of the ceratopsian order. He was about 25 centimeters high, 60 centimeters long, and weighed about seven kilograms. Unlike its much larger relatives - for example, Triceratops and Pentaceratops - Microceratops moved on two legs. Its closest relative was the Psittacosaurus, one of the few dinosaurs eaten by Mesozoic mammals, and not the other way around.

Fourth place: raptorex

Tyrannosaurus rex - the king of all dinosaurs - was about 12 meters from head to tail and weighed seven to eight tons. However, one of his relatives - raptorex, who lived about 60 million years before him, weighed only around 70 kilograms. It's also worth mentioning that Nanotyrannus is considered by some to be the smallest Tyrannosaurus rex, but today it's generally accepted that it was actually a juvenile T-Rex.

Fifth place: Europasaurus

When it comes to sauropods, people most often think of huge house-sized herbivores like Diplodocus and Argentinosaurus. But Europasaurus was little more than a modern bull - about three meters long and weighing less than a ton.

Giants.

First Place: Austroposeidon Magnificus

In 1953, part of the spine and a rib were dug up in the Brazilian municipality of Presidente Prudente in the suburbs of São Paulo. These fossils were in the museum for more than 60 years before Brazilian researchers were able to study them and announce in 2016 that they belong to a new species of titanosaurs. The dimensions of these fossils indicate that an adult Austroposeidon magnificus was 25 meters long. Based on the layers of agrilite and sandstone fossils, it lived between 84 and 66 million years ago.

Second Place: Dreadnoughtus

Dreadnoughtus was one of the largest titanosaurs. It was 26 meters long and weighed about 59 tons. The remains of the dreadnought were discovered in the stone deposits of Southern Patagonia in Argentina, where it lived about 77 million years ago. Now only one species of dreadnoughtus is known to science - Dreadnoughtus schrani.

Third place: paralithitan

For the first time, Paralititan stromeri is the only known species paralithitan - was described in 2001, after earlier excavations 300 kilometers from Cairo. Then they found a 1.69-meter femur, as well as fragments of the shoulder blades, bones of the front legs, teeth and vertebrae. The discovery of such a huge femur allowed paleontologists to speculate that the paralithitan could compete in size with the Argentinosaurus itself. In length, this giant was from 25 to 30.5 meters, and weighed from 60 to 75 tons. Paralithitan lived in the middle of the Cretaceous period, about 94 million years ago.

Fourth Place: Titanosaurus Patagotitan mayorum

Based on its size, Patagotitan mayorum may have been the largest land animal of all time. It is believed that this dinosaur weighed about 70 tons, and was 37.2 meters long. Although some scientists believe that these figures are exaggerated. Patagotitan mayorum lived in Patagonia approximately 95-100 million years ago.

Fifth place: Argentinosaurus

Argentinosaurus has been known to science since 1993. Initially, in 1987, a fossil the size of an adult was dug up on a ranch in Argentina. The farmer thought it was a piece of petrified wood. In 1993, it was found to be a vertebra fossil from a new species of sauropod.

Despite the fact that no complete Argentinosaurus skeletons have been found, calculations of the size of this dinosaur show that it was from 37 to 40 meters in length and weighed from 90 to 100 tons.

As reported by “Around the World. Ukraine",

Life publishes rating prehistoric giants compiled by Stepan Saveliev. This Moscow schoolboy became famous after his mother published a post on the social network with a request to support her son and put likes under his publications. The fact is that classmates called the boy a "loser" due to the fact that he is fond of dinosaurs, and does not play computer games like everyone else. As a result, Styopa instantly became the star of Runet and federal TV channels. Life offered Styopa to try out as a freelance writer.

"I analyzed 10 dinosaurs that managed to distinguish themselves in some way. I hope no one will be offended that I allowed myself to joke a little."

1 Spinosaurus

Most big predator. It is easy to recognize him by the sail that grows on his back. This sail reached 2-4 meters in height! Probably, if desired, the spinosaurus could become a hang glider! Spinosaurus was 16 meters long, 5-8 meters high, weighed from 4 to 14 tons. Its long jaw allowed it to hunt fish and other aquatic creatures. During periods of drought, he ate other dinosaurs, and did not disdain carrion. This comrade also managed to light up in films and cartoons. He was the one who defeated the Tyrannosaurus Rex in Jurassic Park 3.

Recommendation: if you put him on a chain and put him on a huge raft, then his sail will help to go on the right course, especially if he is turned in the right direction with the help of feed. And if this sail is painted red, then you can take it off at the same time " Scarlet Sails"in diversion. A sort of Godzilla from the ocean under scarlet sails.

2. Tyrannosaurus rex

Probably the most famous dinosaur in the world. In total, more than 30 individuals were found, there are also almost complete skeletons. This is a very large predator, reaching 13 meters in length and 4 meters in height, weighing almost 7 tons. He ran pretty fast at that weight - his speed was from 40 to 70 km per hour. Real car! At the same time, he was quite nasty and harmful in nature. He's a cannibal, which means he ate his own kind.

True, you can laugh at him (at a distance, of course): he had very short front legs, like a crocodile from a cartoon about bad teeth. So, most likely, his teeth also hurt, he could hardly brush them.

3. Torosaurus

My favorite dinosaur with one of the biggest skulls. But I love him not only for this. Found for the first time quite a long time ago, back in the 19th century. Its size was about 8 meters, and the skull was 3 meters long, that is, more than a third of the entire dinosaur was a head. This means that he could be very smart! He was pretty heavy. Herbivorous. And he also managed to light up in "Jurassic Park - 3". The torosaurus has a beak that helps it deftly bite leaves and branches. It was not aggressive in itself, but could defend itself well, having very large and strong horns. Not every predator would dare to contact a torosaurus - who wants to become a victim of dinocorrida? Torosaurus also had a large bony collar, larger than Triceratops, which is similar in appearance to Torosaurus. Not confused yet?

Recommendation: Due to its non-aggressiveness and intelligence, it can be used as a large pet. For example, how some keep elephants. Surely you can teach him some tricks and then perform with him.

4 Stegosaurus

A dinosaur with a very small brain, only the size of Walnut! This is a very beautiful and unusual dinosaur. This is the usual combination of beauty and intelligence for those times. He has plates on his back that helped him cool or warm the body. Some scientists think that he could move these plates like a butterfly's wings. It was a little short of a Tyrannosaurus rex in length, was about 9 meters long, and weighed about four and a half tons. Stegosaurus was a herbivore, usually grazed like a cow. Didn't give milk. But his hind legs were stronger than his front ones, so he could pluck trees in search of food. Despite the fact that he was a herbivore, he was quite dangerous - there were spikes on his tail, and a blow with such a tail could be fatal for many dinosaurs! It is said that his plates could be painted in very bright colors. To attract the attention of female dinosaurs, and vice versa. In fact, until now, scientists do not know what color dinosaurs actually were, so we can only fantasize.

5. Allosaurus

This is one of the first dinosaurs found. His remains were discovered back in the 19th century, in 1877. It's also a movie star dinosaur, just like the Tyrannosaurus Rex. He acted in the movie lost World"(Based on the novel by K. Doyle) and" And Thunder Rang "(based on the novel by R. Bradbury). The Allosaurus is a predatory and very large dinosaur. It is quite dangerous, but smaller in size than the Tyrannosaurus Rex, and much lighter than it. It is faster It moved. It reached a length of 9-10 meters, and its front paws were also small, like those of a tyrannosaurus rex, though longer. On its front paws it had three large and very dangerous dirty claws. Allosaurus males quarreled with their females dangerous: they could scratch out their eyes.An interesting fact: the allosaurus could breathe like birds, not exhaling air from its mouth, but blowing it out through special holes in the vertebrae. technical solution, but this helped him to pursue prey for a long time without losing his breath. Which, as it were, did not exist.

Recommendation: due to its excellent physical shape and the presence of special holes, it can be used to participate in a marathon race. True, ahead will have to release prey, which he will pursue. It is unlikely that it will be possible to agree with him in a good way. Brains are also a problem.

6 Argentinosaurus

One of the largest dinosaurs found. Its length is from 22 to 35 meters, and its height is 12-14 meters. Like a five-story building! Can you imagine? This "meat house" weighed about 70-75 tons. How much does the first American reusable transport weigh? spaceship"Enterprise". Of course, it is impossible to feed such a monster with meat. He was a herbivore - he ate grass, leaves, twigs. Really, honey? Naturally, with its size, few people could pose a danger to him at all, except that small predators, like piranhas, could fly into him in a flock and gnaw. He would not have had time to escape from them, but he could fight back for a long time, especially if the flock was small. He didn't move very fast. four legs, he had them powerful and the same, like an elephant.

7 Seismosaurus

One of the longest dinosaurs. Reached a length of 50 meters. He is also one of the heaviest dinosaurs. Its weight reached 140 tons! It's like the E-100 tank, for those who understand. This cutie ate grass and leaves. It had a oh-very long neck and a oh-oh-very long tail. In general, this dinosaur moved on four legs almost parallel to the ground. Of course, he could not rise on his hind legs, but he could lift his neck up to get to higher leaves, when he had already eaten everything below. No one contacted such a dinosaur, therefore he himself was harmless, and few people attempted on him. The main thing here is not to get caught under his paws or tail. If he wandered into a swampy area, he could get bogged down, so he mostly wandered on land, sometimes reaching the surface of swamps and lakes, and could not even climb into forests due to his size. Poor!

8 Apatosaurus

The dinosaur with two names and the most learning errors. Scientists gave him a strange name and attributed someone else's head. The skulls of herbivorous dinosaurs are rarely preserved because the bones of such a skull are usually small and decay more quickly. His second name is brontosaurus. A very large dinosaur. Reached a length of 20 meters and weighed about 17- 20 tons. But at the same time, his brain weighed only 400 grams. Not the smartest dinosaur. But he could stand on his hind legs, which is all for dinosaurs with such a long neck. yo - a rarity. Apatosaurus lived in packs.They had a rather long neck and a long tail.They walked, lifting him off the ground, otherwise the comrades walking behind could crush him.

9. Eorpator

One of the earliest dinosaurs. Lived in Triassic almost 230 million years ago. It was very small, only 1 meter in length, and weighed only 10 kilograms. Almost like a dog. He was a predator, therefore, of course, it is better not to keep such a pet as a pet.

10. Compsognathus

One of the smallest dinosaurs. This baby was less than a meter long, usually 60-70 centimeters, and weighed up to 3 kilograms. Like a cat. True, he has more teeth than a cat - 68 pieces! Of course, so many teeth are needed not to chew grass. It was a predator. Very harmful, like any small predators. Given his small size, he needed to live in a pack. Alone, such kids have little chance of a good hunt, and it’s more fun to defend yourself in a crowd. He fed on lizards and insects. He had a very mobile neck, like an owl, he could rotate it along a very large radius. A long tail helped him keep his balance while running fast. He ran on two hind legs, the front legs were short. With them, he probably held prey while eating, like a hamster. These small boogers also took part in "Jurassic Park - 2". The man was eaten. Mercenary.

Eoraptorlunensis is considered the most primitive of all dinosaurs. It received this name in 1993, when in the foothills of the Andes, located on the territory of Argentina, in rocks that are 228 million years old, researchers discovered the skeleton of this creature. This dinosaur, whose body length reached 1 m, scientists attributed to theropods - carnivorous dinosaurs from the order of ornithischians.

Therizinosaurus was named the most ridiculous dinosaur

Its legs resembled bird's paws, each of which had 4 functional fingers, and a toothless beak "flaunted" at the end of the creature's muzzle.

Sauropods were representatives of the suborder of lizard dinosaurs. They were incredibly different from other monsters. long neck and tail. Sauropods moved on four limbs. These herbivorous dinosaurs inhabited most of the land in the Cretaceous and jurassic periods(208-65 million years ago).

Scientists believe that the heaviest dinosaurs were:

• The titanosaurs Antarctosaurus giganteus (giant arctic lizards) have been fossilized in Argentina and India. Their weight reached 40-80 tons. Moreover, the approximate weight of the Argentinean titanosaurus (Argentinosaurus) could reach up to 100 tons. Such estimates were made in 1994 based on measurements of the size of its giant vertebrae.
• Brachiosaurus altithorax (hand-lizards), which got their name from their long forelimbs. The weight of these giants was 45-55 tons.
• Diplodocus Seismosaurus halli (earth-shaking lizards) and Supersaurus vivianae, which weighed over 50 tons, and according to some sources could approach 100 tons.

The largest and tallest type of dinosaur

the skeleton of which managed to be completely preserved was found in Tanzania, and more precisely in Tedaguru, Brachiosaurus brancai. Its remains were found in the late Jurassic deposits formed 150-144 million years ago. Excavations were carried out in 1909-1911 by German expeditions. The preparation of the bones and the assembly of the skeleton took place at the Museum of Natural History at the Humboldt University in Berlin. The dinosaur skeleton was created from the bones of not one, but several individuals in 1937. The total body length of the brachiosaurus was 22.2 m, the height at the withers was 6 m, and the height with a raised head was 14 m. During his life, his weight, according to scientists, reached 30-40 tons. The tibia of another brachiosaurus, also kept in the museum, suggests that these dinosaurs could have been much larger.

The longest dinosaurs were

the brachiosaurus Breviparopus, whose body length could be 48 m, and the diplodocus Seismosaurus halli, discovered in the US state of New Mexico in 1994, whose body length reached 39-52 m. The basis for obtaining such estimates was the comparison of animal bones.

The smallest dinosaurs are considered

cosmognatus (graceful jaw) that lived in the southern part of Germany and the southeastern region of France; and a little-studied herbivorous fabrosaurus that lived in the territory of the US state of Colorado. The length of these creatures, from the tip of the nose to the tip of the tail, was 70-75cm. The weight of the first reached 3 kg, the weight of the second - 6.8 kg.

Ankylosaurs are considered the most armored

of all the dinosaurs that existed on our planet. Their head and back were securely protected by bone plates, spikes and horns. The width of their body was about 2.5 m. Their main hallmark there was a tail, at the end of which a huge mace flaunted.

The largest footprints of a prehistoric lizard

there were traces discovered in 1932 on the territory of Sol Lake City, Utah. They belonged to a large hadrosaur (platypus) moving on its hind limbs. The tracks were 136 cm long and 81 cm wide. In other reports from Colorado and all the same Utah, it was said about another track 95-100m wide. According to some reports, the width of the traces of the hind legs of the largest brachiosaurs can reach 100 cm.

The largest skull

belonged to a torosaurus, a herbivorous lizard that wore a huge bone shield around its neck. The length of this dinosaur could reach 7.6 m, and weight - 8 tons. The length of the skull alone, together with the ossified “frill”, was 3 m, and its weight was about 2 tons. This "brainy" creature lived on the territory of modern American states Texas and Montana.

In the line of the most toothy dinosaurs

in the first place are the ornithomimids Pelecanimimus (bird-like dinosaurs). They had over 220 incredibly sharp teeth in their mouths.

The owners of the longest claws

were therizinosaurs found in the Late Cretaceous deposits of the Nemegt basin, located on the territory of Mongolia. The length of their claw along the outer curvature could reach 91 cm. In Tyrannosaurus rex, for comparison, this value was 20.3 cm. Therizinosaurus had no teeth at all, and the skull was rather fragile. This lizard ate, according to scientists, termites.

Spinosaurus could also boast of its long claws, the total length of which reached 9 m, and its weight was about 2 tons. In January 1983, an amateur paleontologist William Walker discovered a 30 cm long claw belonging to a spinosaurus near the English Dorking.

The largest eggs

Of all the dinosaurs known to science, the 12-meter titanosaur Hypselosaurus priscus, who lived on our planet about 80 million years ago, laid aside. Fragments of his egg were discovered in October 1961 in the valley of the French river Durance. According to the assumptions of scientists, its dimensions as a whole were 25.5 cm in diameter, 30 cm in length, and its capacity was 3.3 liters.

The trails created by dinosaurs are used by scientists to determine the speed of these animals. So found on the territory of the US state of Texas in 1981, the trail allowed the researchers to conclude that a certain carnivorous dinosaur was able to move at a speed of 40 km / h. Some ornithomimids are known to be able to run even faster. For example, the owner of a large brain, a 100-kilogram Dromiceiomimus, who lived at the end of the Cretaceous period on the territory of modern Canadian province Albert, could easily overtake an ostrich, whose speed of movement can exceed 60 km / h.

The smartest dinosaurs

troodontids are considered, whose brain mass in relation to their body mass was comparable to the same parameters that the most intelligent birds possess.

Living 150 million years ago in the territory of the modern American states of Oklahoma, Colorado, Wyoming and Utah, the stegosaurus could reach a length of 9m. However, the brain of this creature did not exceed the size of a walnut, and its weight was only 70 g, which was only 0.002% of the mass of its entire body, which averaged 3.3 tons.

If you think that we have told everything about dinosaurs, then this is not so. In fact, there are still a lot of open questions and interesting facts about these ancient creatures.
