Do dinosaurs have ears? Multimedia presentation "Animals of the past
Hello, dear friends! We are glad to welcome you to our children's page. You've probably heard about them, and maybe even seen them in movies and cartoons. We will tell you a lot of interesting things about dinosaurs. Chances are you have a lot of questions about these wonderful animals. We will try to answer them.
How long did dinosaurs live?
It has not yet been possible to answer the question at what age dinosaurs died. But they don’t give up trying to do it. Scientists are trying to estimate the lifespan of dinosaurs by the growth rate of fossil bones. This does not seem to be the case for determining the age of trees by tree rings.
Is it true that a dinosaur's lifespan depended on its size?
Scientists suggest that large dinosaurs lived longer than small ones. The little dinosaur developed and grew faster and lived life more intensely.
Which dinosaur was the biggest?
The most big dinosaur there was a seismosaur. Part of his skeleton was found in the USA, but the excavations are not over yet. Scientists suggest that this dinosaur weighed more than 50 tons and was about 36 m long
Did dinosaurs live in the sea?
Dinosaurs did not live in the sea, as do whales or dolphins, for example. Dinosaurs could enter the water to hunt fish or swim across a river to save them from a predator. But no dinosaur spends its entire life in the sea. Dinosaurs should not be confused with such sea inhabitants Mesozoic era like pliosaurs or plesiosaurs
Could dinosaurs fly?
Dinosaurs could neither fly nor glide. All dinosaurs were wingless land animals. But at the same time, reptiles lived with dinosaurs, which were relatives of dinosaurs, but could fly. They are called pterosaurs. Also, in the Jurassic period there was an animal called Archeopteryx. Archeopteryx was not a dinosaur. Scientists are still arguing about whether Archeopteryx is classified as a bird or a reptile. Outwardly, he looked like a bird, but the claws and teeth were like those of a reptile
Which dinosaur had the biggest teeth?
One of the largest dinosaur teeth ever discovered belonged to a Tyrannosaurus rex. This tooth was located in the side of the jaw, not far from the front teeth. The length from root to apex was about 30 cm. And the tooth did not rise above the gum of the tyrannosaurus 18 cm.
Which dinosaur had the most long neck?
Of all the dinosaurs known to paleontologists at the moment, Mamenchisaurus is considered the longest-necked one. Mamenchisaurus lived about 150 million years ago. on the territory of modern China. The neck of Mamenchisaurus was about 14 m long. Mamenchisaurus could easily peer through the roof of a three-story building. Perhaps when it is dug up complete skeleton seismosaur, it will be the longest-necked dinosaur.
Which dinosaur ran the fastest?
Scientists suggest that the fastest dinosaurs were ornithomemmosaurs - ostrich-like dinosaurs. This group includes such dinosaurs as: galimmymus, ornithomimus, pelicanim , struthiomeme. Scientists suggest that these dinosaurs reached speeds of up to 50 km/h.
Did dinosaurs fall into hibernation?
During the Triassic and Jurassic periods The climate on earth was warmer and wetter than it is now. Moreover, all the land was not very far from the equator. Therefore, there was no need for dinosaurs to hibernate. Later, in the Cretaceous period, the continents began to diverge further and further. Antarctica began to shift towards the south pole. At the end Cretaceous period The climate on earth began to change, and the differences in temperatures between summer and winter became stronger. The winter of the Cretaceous period was not as severe as it is now, but still, the temperature could drop to 0 °C. At this temperature, cold-blooded reptiles such as dinosaurs became very cold. Therefore, it is very likely that they hibernated to avoid freezing.
How big were dinosaur eggs?
Dinosaur eggs vary in size. Eggs only 2-3 cm long were found near the Mussaurus skeleton. large dinosaurs from the sauropod group, the eggs were much larger. But still, even the largest dinosaur egg found was no larger than a soccer ball.
Did dinosaurs have ears?
Dinosaurs had small bones in their skulls that transmitted sound from the eardrum to the parts of the brain responsible for hearing. In the general sense, dinosaurs did not have ears. The dinosaur's "ears" were small holes on the sides of its head. The ears of modern lizards look the same.
Which dinosaur had the most teeth?
Hadrosaurs, duck-billed dinosaurs, had the most teeth. Hadrosaurs had 480 teeth on their lower and upper jaws. That is, a total of 980 teeth. Considering that dinosaurs' teeth were restored, it can be assumed that hadrosaurs replaced about 10,000 teeth throughout their lives.
Did dinosaurs have fur?
So far, no evidence has been found that dinosaurs had fur. However, we are unlikely to ever be able to find out for sure. Fur is a soft and delicate material and it could not survive for many millions of years. However, none of the modern reptiles have fur. Therefore, most likely dinosaurs also did not have fur.
Did dinosaurs know how to climb trees?
It is possible that some small dinosaurs They were agile and agile enough that they could easily climb trees and jump on branches. Most dinosaurs were too large and heavy to climb trees. Gigantic herbivorous dinosaurs they could simply knock down a tree to get to the luscious foliage.
Did dinosaurs have a developed sense of smell?
Some dinosaurs breathed through quite big nostrils. The part of the dinosaur's brain responsible for smell was also large. Therefore, most likely, dinosaurs’ sense of smell was well developed.
Is it true that dinosaurs swallowed rocks?
Yes, some dinosaurs swallowed rocks. These stones are also called gastroliths. They served to grind hard leaves and shoots directly in the dinosaur's stomach. Similarly, modern chickens swallow small pebbles to help them digest grain.
Was there a brontosaurus?
A few years ago a set was released in the USA postage stamps with dinosaurs. This caused confusion. The dinosaur depicted on one of the stamps was mistakenly called a brontosaurus. This name, meaning “thunder lizard,” was coined by paleontologist O.K. March in 1879 But two years earlier, the dinosaur with such a skeleton was named Appatosaurus. Therefore, there is no dinosaur called Brontosaurus. This dinosaur should be called Appatosaurus.
Why did dinosaurs need claws?
Dinosaurs used their claws for a variety of purposes. The claws of predators, sharp and thin as daggers, were used to tear the meat of the victim. Wide and flat claws replaced hooves and served as support when walking. There were also other types of claws adapted for digging the ground, scratching, and protecting from enemies.
Did dinosaurs form herds?
Scientists have found much evidence that some species of dinosaurs led a gregarious lifestyle. During excavations, thousands of bones belonging to one type of dinosaur were discovered collected in one place. Presumably the piles of bones are the remains of herds that died as a result of a sudden natural disaster.
Did dinosaurs migrate?
Dinosaurs could migrate over vast distances in search of food or nesting sites. The remains of dinosaurs discovered by paleontologists indicate that some species of dinosaurs crossed entire continents during such migrations. Nowadays, some birds, flying to warmer regions, cover no less impressive distances.
Has man ever met dinosaurs?
The last dinosaurs disappeared around 65 million years ago. at the end of the Cretaceous period. The first people, according to scientists, appeared about 150 thousand years ago. This means humans appeared more than 64 million years after the extinction of the dinosaurs. It is unlikely that any people could meet a living dinosaur.
Did dinosaurs use camouflage?
Like many modern animals, some dinosaurs needed to be invisible. This is necessary either to hide or to sneak up unnoticed. Perhaps the color of dinosaurs allowed them to hide well in the area where they lived.
How do paleontologists distinguish the tracks of different dinosaurs from each other?
Only a specialist can determine which dinosaur left this or that trace. First, paleontologists study the shape of both the feet and fingers. They then study the age of the rock in which the fossilized dinosaur footprint was found. After this, the found prints are correlated with the appearance of those dinosaurs that lived during the era of the formation of the rock.
Did dinosaurs see well?
As far as we can tell, most dinosaurs had very good eyesight. The eye sockets of the dinosaurs found are large, therefore the eyes were large. The areas of the brain responsible for vision are also well developed.
What color were dinosaurs?
No one knows what color dinosaurs were. The fact is that dinosaur skin is a very rare find. However, no coloring pigments were preserved in the fossils found. Experts believe that the color of dinosaurs corresponded to their habitat. And it was adapted for camouflage. But some dinosaurs did not need camouflage coloring, because due to large sizes had no enemies. In this case, scientists can only speculate.
How can fossils be protected from damage during transport to the laboratory?
The fossilized remains of dinosaurs are removed from the earth with the greatest care. Each bone is wrapped in tissue paper and then cast in plaster. The plaster hardens and protects the bones from damage during transportation.
Did dinosaurs eat eggs?
Some dinosaurs ate the eggs of other animals. One of these dinosaurs was Oviraptor. Oviraptor means "egg stealer", precisely because it robbed the nests of other dinosaurs. In the oviraptor's mouth there were special growths with which it cracked eggs.
How do scientists determine the age of fossils?
Fossils are found in rocks made of sedimentary rocks. Over millions of years, the rocks have been modified by the wind, sunlight rain and temperature changes. The age of a fossil is judged by its layer. rock in which it was discovered. In addition, radioactive elements help determine the age of dinosaur remains. Scientists measure the level of radioactivity in fossilized bones and, based on these measurements, determine the approximate age of the dinosaur.
Which dinosaur had the most big eyes?
Dromiceomimus had huge eyes. His name means "emu-like." Judging by the fossil skulls of this lizard, its eye sockets were larger than those of any other famous dinosaur. Therefore, Dromiceomimus is considered the largest-eyed dinosaur. The eyes of Dromiceomimus were located on the sides of the head, which provided excellent visibility and an advantage over predators.
Did dinosaurs sweat?
Dinosaurs couldn't sweat. The dinosaur's skin was scaly and had no pores through which sweat could escape.
Which dinosaur came first?
Two lizards compete for the title of being the first dinosaur in the history of the earth. These are Herrerosaurus and Eoraptor. Both of them were bipedal predators and lived around 230-225 million years ago. The search for fossils continues and it is possible that even more ancient dinosaurs will be discovered.
How do dinosaurs get their names?
Since the 1820s, paleontologists have been inventing dinosaur names. Having discovered the remains of a new species of dinosaur, scientists describe the discovery in a special diary. In the future, in order to distinguish this species from others, a special name is chosen for it, which has never been used before. Often the name contains the name of the area in which the dinosaur was found.
Could dinosaurs smell?
Many dinosaurs had an excellent sense of smell. This helped them from afar to smell a predator, prey or a potential mate. It is also likely that dinosaurs could emit special signal odors, like many animals.
Did dinosaurs build their own houses?
Most dinosaurs were too large to build homes for themselves. However, some dinosaurs built nests for themselves to lay eggs.
Is there a place on earth where dinosaurs did not live?
The remains of dinosaurs have been found on all continents of the Earth. Until recently, it was believed that there were no dinosaurs in Antarctica. Over the past few years on rocky coasts On this icy continent, the fossil remains of an armored dinosaur and a small herbivorous dinosaur were found.
Why are so many fossils found in Alberta, Canada?
During the time of the dinosaurs, the area that is now called the Alberta Wastes was literally crawling with dinosaurs. This was the intersection of the routes along which dinosaurs migrated from south to north and from north to south. In Alberta national park Hundreds of dinosaur skeletons found prehistoric lizards. A large burial was discovered, from which the bones of more than 50 dinosaurs were extracted.
Did dinosaurs sleep?
All animals, including humans, need sleep and rest. And dinosaurs are no exception. Modern reptiles spend most of their lives sleeping. And there is no reason to believe that dinosaurs could survive without sleep.
Were all dinosaurs bloodthirsty?
Most dinosaurs were peaceful herbivores. Most of the time they grazed. There were much fewer predators.
Did dinosaurs maintain mating relationships throughout their lives?
Experts are inclined to believe that dinosaurs did not create stable mating pairs. But some dinosaurs nested together and looked after their offspring. However, it is unlikely that the male and female remained together for a long time after mating.
How long did it take for baby dinosaurs to develop in eggs?
To date, it is not known how long it took dinosaurs to develop in eggs. One can only speculate on this matter. It is only known that some dinosaurs, for example Maiasaurs, led nomadic image life, but came to the same place to lay eggs.
Which dinosaur had the most long tail?
Diplodocus had the longest tail. The length of the diplodocus tail reached 11 meters. Diplodocus used it as a whip to drive away predators.
Did dinosaurs live in caves?
Most dinosaurs were too big. They wouldn't fit in the cave. Some paleontologists believe that small dinosaurs could have hidden in caves in dry periods. But this is just a guess.
How did dinosaurs sleep?
How dinosaurs slept remains a mystery. Perhaps large herbivorous dinosaurs slept standing up. As for predators, for example, the tyrannosaurus had large curved bones in the lower part of the pelvis, and under the ribs there was additional row bones. This allowed the tyrannosaurus to lie on the ground without fear, and protected it internal organs from overload.
Did dinosaurs eat fruit?
Some dinosaurs, such as Ornithomimus, had toothless jaws, like modern ostriches. They belong to the group of omnivorous dinosaurs. Their diet included insects, small animals, roots and possibly fruit. It is also impossible that other dinosaurs could eat fruit.
How much meat could a Tyrannosaurus rex eat in a day?
Given its size, a hungry tyrannosaurus could eat 120-150 kg of meat at one time. After such a lunch, the dinosaur could go without food for several days.
Did all other reptiles go extinct along with the dinosaurs?
No. Many reptiles were able to survive and even live to this day. These are lizards, snakes, turtles and crocodiles.
Did dinosaurs blink?
Dinosaurs had eyelids, so they could blink. Interesting find turned out to be eyelids armored dinosaurs ankylosaurs. These dinosaurs had bony eyelids. When the ankylosaur lowered its eyelids, its eyes were reliably protected.
Were there viviparous dinosaurs?
Scientists do not yet know of any evidence that viviparous dinosaurs existed. All dinosaurs found laid eggs. Reptiles that lived in the sea adapted to viviparity, but they were not dinosaurs.
Did dinosaurs shed their skin like lizards do?
Dinosaurs are not closely related to lizards. Their skin has a different structure. The outer layers of skin were not completely shed, but in small fragments, like those of crocodiles.
How did dinosaurs keep themselves clean?
Dinosaurs had no fur or wool, so their skin did not need to be cleaned. The dirt that stuck to the skin of dinosaurs either dried up and fell off, or was shed along with old skin scales, like modern reptiles. The skin of dinosaurs was constantly renewed.
Report for children. Children about dinosaurs.
From numerous reptiles dinosaurs that inhabited the Earth have been studied quite well. They appeared approximately 220 million years ago. The word "dinosaur" means "terrible lizard."
Their bones, footprints, teeth and even eggs are found all over the world. Dinosaur skeletons have become fossilized over time. By studying the fossilized remains of ancient lizards, paleontologists found that their skin was scaly and sealed, and that some dinosaurs lived up to a hundred years!
Dinosaurs laid eggs in specially designed nests, often up to ten eggs at a time! These eggs, round or oval, covered with a hard shell, were quite small compared to the lizards themselves.
Tyrannosaur was the most large predator era of dinosaurs and terrified all other lizards. The height of this giant was 6 meters, and the body - from tail to head - reached 15 meters. This one has scary predator the teeth were sharp as daggers. Despite huge size, the Tyrannosaurus rex could run at a speed of 30 km/h!
Compsognathus- the smallest of all dinosaurs. This turkey-sized predator fed on insects and lizards. In order not to get caught in the teeth and become prey to its larger brothers, Compsognathus ran quickly - hind legs his were long and strong.
Diplodocus was truly the greatest of all dinosaurs: the giant’s body reached 25 meters in length and ended with a long tail; an almost equally long neck ended with a very small head. Diplodocus fed on algae and leaves of bushes. To protect himself from enemies, he used his powerful tail as a huge whip and beat his attackers with it. Diplodocus lived in North America. In addition to numerous individual bones, one complete skeleton of this dinosaur was found there.
Parasaurolophus looked quite bizarre: on his head he had a long bony crest, especially developed in males. Parasaurolophus were able to distinguish each other by their heads and, with its help, made their way through the forest thicket. This peaceful lizard lived near bodies of water and could swim a little.
Stegosaurus. The stegosaurus had a large body and a very tiny head. To protect yourself from voracious predators, on the back of the stegosaurus there were bone plates that grew in two rows from head to tail, as well as four half-meter spikes at the end of a powerful and movable tail.

Hello, dear friends! We are pleased to welcome you to our educational page. You've probably heard about them, and maybe even seen them in movies and cartoons. We will tell you a lot of interesting things about dinosaurs. Chances are you have a lot of questions about these wonderful animals. We will try to answer them.

Scientists suggest that large dinosaurs lived longer than small ones. The little dinosaur developed and grew faster and lived life more intensely.
Which dinosaur was the largest?
The largest dinosaur was Seismosaurus. Part of his skeleton was found in the USA, but the excavations are not over yet. Scientists suggest that this dinosaur weighed more than 50 tons and was about 36 m long
Did dinosaurs live in the sea?
Dinosaurs did not live in the sea, as do whales or dolphins, for example. Dinosaurs could enter the water to hunt fish or swim across a river to save them from a predator. But no dinosaur spent its entire life at sea. Dinosaurs should not be confused with such inhabitants of the seas of the Mesozoic era as pliosaurs or plesiosaurs
Could dinosaurs fly?
Dinosaurs could neither fly nor glide. All dinosaurs were wingless land animals. But at the same time, reptiles lived with dinosaurs, which were relatives of dinosaurs, but could fly. They are called pterosaurs. Also, during the Jurassic period there was an animal called Archeopteryx. Archeopteryx was not a dinosaur. Scientists are still arguing about whether Archeopteryx is classified as a bird or a reptile. Outwardly, he looked like a bird, but his claws and teeth were like those of a reptile.
Which dinosaur had the biggest teeth?
One of the largest dinosaur teeth ever discovered belonged to a Tyrannosaurus rex. This tooth was located in the side of the jaw, not far from the front teeth. The length from root to top was about 30 cm. And above the gum of the tyrannosaurus, the tooth rose 18 cm.
Which dinosaur had the longest neck?
Of all the dinosaurs currently known to paleontologists, Mamenchisaurus is considered the longest-necked. Mamenchisaurus lived about 150 million years ago. on the territory of modern China. The neck of Mamenchisaurus was about 14 m long. Mamenchisaurus could easily peer through the roof of a three-story building. Perhaps, when the complete skeleton of Seismosaurus is dug up, it will turn out to be the longest-necked dinosaur.
Which dinosaur ran the fastest?
Scientists suggest that the fastest dinosaurs were ornithomemmosaurs - ostrich-like dinosaurs. This group includes such dinosaurs as: galimmimus, ornithomimus , pelicanim , struthiomeme . Scientists believe that these dinosaurs reached speeds of up to 50 km/h.
Did dinosaurs hibernate?
During the Triassic and Jurassic periods, the climate on earth was warmer and wetter than it is now. Moreover, all the land was not very far from the equator. Therefore, there was no need for dinosaurs to hibernate. Later, in the Cretaceous period, the continents began to diverge further and further. Antarctica began to shift towards south pole. At the end of the Cretaceous period, the climate on earth began to change, and the differences in temperatures between summer and winter became increasingly stronger. The winter of the Cretaceous period was not as severe as it is now, but still, the temperature could drop to 0 °C. At this temperature, cold-blooded reptiles such as dinosaurs became very cold. Therefore, it is very likely that they hibernated to avoid freezing.
How big were dinosaur eggs?
Dinosaur eggs vary in size. Eggs only 2-3 cm long were found near the Mussaurus skeleton. Large dinosaurs from the sauropod group had much larger eggs. But still, even the largest dinosaur egg found was no larger than a soccer ball.
Did dinosaurs have ears?
Dinosaurs had small bones in their skulls that transmitted sound from the eardrum to the parts of the brain responsible for hearing. But in the general sense, dinosaurs did not have ears. The dinosaur's "ears" were small holes on the sides of its head. The ears of modern lizards look the same.
Which dinosaur had the most teeth?
Hadrosaurs, duck-billed dinosaurs, had the most teeth. Hadrosaurs had 480 teeth on their lower and upper jaws. That is, a total of 960 teeth. Considering that dinosaurs' teeth were restored, it can be assumed that hadrosaurs replaced about 10,000 teeth throughout their lives.
Did dinosaurs have fur?
So far, no evidence has been found that dinosaurs had fur. However, we are unlikely to ever be able to find out for sure. Fur is a soft and delicate material and it could not survive for many millions of years. However, none of the modern reptiles have fur. Therefore, most likely dinosaurs also did not have fur.
Did dinosaurs know how to climb trees?
It is possible that some small dinosaurs were agile and agile enough that they could easily climb trees and jump on branches. Most dinosaurs were too large and heavy to climb trees. Giant herbivorous dinosaurs could simply knock down a tree to get to the luscious foliage.
Did dinosaurs have a developed sense of smell?
Some dinosaurs breathed through rather large nostrils. The part of the dinosaur's brain responsible for smell was also large. Therefore, most likely, dinosaurs’ sense of smell was well developed.
Is it true that dinosaurs swallowed rocks?
Yes, some dinosaurs swallowed rocks. These stones are also called gastroliths. They served to grind hard leaves and shoots directly in the dinosaur's stomach. Similarly, modern chickens swallow small pebbles to help them digest grain.
Was there a brontosaurus?
A few years ago, a set of postage stamps with dinosaurs was released in the United States. This caused confusion. The dinosaur depicted on one of the stamps was mistakenly called a brontosaurus. This name, meaning “thunder lizard,” was coined by paleontologist O.K. March in 1879 But two years earlier, a dinosaur with the same skeleton was named Appatosaurus. Therefore, there is no dinosaur called Brontosaurus. This dinosaur should be called Appatosaurus.
Why did dinosaurs need claws?
Dinosaurs used their claws for a variety of purposes. The claws of predators, sharp and thin, like daggers, were used to tear the meat of the victim. Wide and flat claws replaced hooves and served as a support when walking. There were also other types of claws adapted for digging the ground, scratching, and protecting from enemies.
Did dinosaurs form herds?
Scientists have found much evidence that some species of dinosaurs led a gregarious lifestyle. During excavations, thousands of bones belonging to one type of dinosaur were discovered collected in one place. Presumably the piles of bones are the remains of herds that died as a result of a sudden natural disaster.
Did dinosaurs migrate?
Dinosaurs could migrate over vast distances in search of food or nesting sites. The remains of dinosaurs discovered by paleontologists indicate that some species of dinosaurs crossed entire continents during such migrations. Nowadays, some birds, flying to warmer regions, cover no less impressive distances.
Has man ever met dinosaurs?
The last dinosaurs disappeared around 65 million years ago. at the end of the Cretaceous period. The first people, according to scientists, appeared about 150 thousand years ago. This means humans appeared more than 64 million years after the extinction of the dinosaurs. It is unlikely that any people could meet a living dinosaur.
Did dinosaurs use camouflage?
Like many modern animals, some dinosaurs needed to be invisible. This is necessary either to hide or to sneak up unnoticed. Perhaps the color of dinosaurs allowed them to hide well in the area where they lived.
How do paleontologists distinguish the tracks of different dinosaurs from each other?
Only a specialist can determine which dinosaur left this or that trace. First, paleontologists study the shape of both the feet and fingers. They then study the age of the rock in which the fossilized dinosaur footprint was found. After this, the found prints are correlated with the appearance of those dinosaurs that lived during the era of the formation of the rock.
Did dinosaurs see well?
As far as we can tell, most dinosaurs had very good eyesight. The eye sockets of the dinosaurs found are large, therefore the eyes were large. The areas of the brain responsible for vision are also well developed.
What color were dinosaurs?
No one knows what color dinosaurs were. The fact is that dinosaur skin is a very rare find. However, no coloring pigments were preserved in the fossils found. Experts believe that the color of dinosaurs corresponded to their habitat. And it was adapted for camouflage. But some dinosaurs did not need camouflage coloring, since due to their large size they did not have enemies. In this case, scientists can only speculate.
How can fossils be protected from damage during transport to the laboratory?
The fossilized remains of dinosaurs are removed from the earth with the greatest care. Each bone is wrapped in tissue paper and then cast in plaster. The plaster hardens and protects the bones from damage during transportation.
Did dinosaurs eat eggs?
Some dinosaurs ate the eggs of other animals. One of these dinosaurs was Oviraptor. Oviraptor means "egg stealer", precisely because it robbed the nests of other dinosaurs. In the mouth of the oviraptor there were special growths with which it cracked eggs.
How do scientists determine the age of fossils?
Fossils are found in rocks made of sedimentary rocks. Over millions of years, the rocks have changed under the influence of wind, sunlight, rain and temperature changes. The age of a fossil is determined by the layer of rock in which it is found. In addition, radioactive elements help determine the age of dinosaur remains. Scientists measure the level of radioactivity in fossilized bones and use these measurements to determine the approximate age of the dinosaur.
Which dinosaur had the biggest eyes?
Dromiceomimus had huge eyes. His name means "emu-like." Judging by the fossil skulls of this lizard, its eye sockets were larger than those of any other known dinosaur. Therefore, Dromiceomimus is considered the largest-eyed dinosaur. Dromiceomima's eyes were located on the sides of its head, which provided excellent visibility and an advantage over predators.
Did dinosaurs sweat?
Dinosaurs couldn't sweat. The dinosaur's skin was scaly and had no pores through which sweat could escape.
Which dinosaur came first?
Two lizards compete for the title of being the first dinosaur in the history of the earth. These are Herrerosaurus and Eoraptor. Both of them were bipedal predators and lived around 230-225 million years ago. The search for fossils continues and it is possible that even more ancient dinosaurs will be discovered.
How do dinosaurs get their names?
Since the 1820s, paleontologists have been inventing dinosaur names. Having discovered the remains of a new species of dinosaur, scientists describe the discovery in a special diary. In the future, in order to distinguish this species from others, a special name is chosen for it, which has never been used before. Often the name contains the name of the area in which the dinosaur was found.
Could dinosaurs smell?
Many dinosaurs had an excellent sense of smell. This helped them from afar to smell a predator, prey or a potential mate. It is also likely that dinosaurs could emit special signal odors, like many animals.
Did dinosaurs build their own houses?
Most dinosaurs were too large to build homes for themselves. However, some dinosaurs built nests for themselves to lay eggs.
Is there a place on earth where dinosaurs did not live?
The remains of dinosaurs have been found on all continents of the Earth. Until recently, it was believed that there were no dinosaurs in Antarctica. Over the past few years, fossil remains of an armored dinosaur and a small herbivorous dinosaur have been found on the rocky coasts of this icy continent.
Why are so many fossils found in Alberta, Canada?
During the time of the dinosaurs, the area that is now called the Alberta Wastes was literally teeming with dinosaurs. This was the intersection of the routes along which dinosaurs migrated from south to north and from north to south. Hundreds of prehistoric dinosaur skeletons have been found in Alberta's Dinosaur National Park. Discovered large burial, from which the bones of more than 50 dinosaurs were extracted.
Did dinosaurs sleep?
All animals, including humans, need sleep and rest. And dinosaurs are no exception. Modern reptiles spend most of their lives sleeping. And there is no reason to believe that dinosaurs could survive without sleep.
Were all dinosaurs bloodthirsty?
Most dinosaurs were peaceful herbivores. Most of they were grazing for a while. There were much fewer predators.
Did dinosaurs maintain mating relationships throughout their lives?
Experts are inclined to believe that dinosaurs did not create stable mating pairs. But some dinosaurs nested together and looked after their offspring. However, it is unlikely that the male and female remained together for a long time after mating.
How long did it take for baby dinosaurs to develop in eggs?
It is currently unknown how long it took dinosaurs to develop in eggs. One can only speculate on this matter. It is only known that some dinosaurs, for example Maiasaurs, led a nomadic lifestyle, but came to the same place to lay eggs.
Which dinosaur had the longest tail?
Diplodocus had the longest tail. The length of the diplodocus tail reached 11 meters. Diplodocus used it as a whip to drive away predators.
Did dinosaurs live in caves?
Most dinosaurs were too big. They wouldn't fit in the cave. Some paleontologists believe that small dinosaurs may have hidden in caves during dry periods. But this is just a guess.
How did dinosaurs sleep?
How dinosaurs slept remains a mystery. Perhaps large herbivorous dinosaurs slept standing up. As for predators, for example, the Tyrannosaurus rex had large curved bones in the lower part of the pelvis, and an additional row of bones located under the ribs. This allowed the tyrannosaurus to lie on the ground without fear, and protected its internal organs from overload.
Did dinosaurs eat fruit?
Some dinosaurs, such as Ornithomimus, had toothless jaws, like modern ostriches. They belong to the group of omnivorous dinosaurs. Their diet included insects, small animals, roots and possibly fruit. It is also possible that other dinosaurs could have eaten fruit.
How much meat could a Tyrannosaurus rex eat in a day?
Given its size, a hungry tyrannosaurus could eat 120-150 kg of meat at one time. After such a lunch, the dinosaur could go without food for several days.
Did all other reptiles go extinct along with the dinosaurs?
No. Many reptiles were able to survive and even live to this day. These are lizards, snakes, turtles and crocodiles.
Did dinosaurs blink?
Dinosaurs had eyelids, so they could blink. An interesting find was the eyelids of armored dinosaurs ankylosaurs. These dinosaurs had bony eyelids. When the ankylosaur lowered its eyelids, its eyes were reliably protected.
Were there viviparous dinosaurs?
Scientists do not yet know of any evidence that viviparous dinosaurs existed. All dinosaurs found laid eggs. Reptiles that lived in the sea adapted to viviparity, but they were not dinosaurs.
Did dinosaurs shed their skin like lizards do?
Dinosaurs are not closely related to lizards. Their skin has a different structure. The outer layers of skin were not completely shed, but in small fragments, like those of crocodiles.
How did dinosaurs keep themselves clean?
Dinosaurs had no fur or wool, so their skin did not need to be cleaned. The dirt that stuck to the skin of dinosaurs either dried out and fell off, or was shed along with old skin scales, like in modern reptiles. The skin of dinosaurs was constantly renewed.
