Tyrannosaurus rex is the largest predatory dinosaur: description with photos and videos. The most terrible predators of the Earth: Tyrannosaurus The largest tyrannosaurus

Tyrannosaurus that lived in Cretaceous period, had a body length of about 14 m; he lived in Asia, North America; it is the largest carnivorous land animal ever to exist.

The largest was the tyrannosaurus, 5-6 meters high and 12 m long. Its mouth was 1 m long. In one sitting, it could swallow prey weighing 200 kg. Tyrannosaurs – the most terrible land predators in the history of the planet. Adults weighed about 5-6 tons, and therefore were 15 times heavier than the largest modern predator - polar bear. The dinosaur that walked the Earth 65 million years ago was the largest land predator of all time.

How long did tyrannosaurs live?
Tyrannosaurs, the most feared land predators in the history of the planet, died young. The predator grew quickly, gaining two kilograms a day, like a modern one African elephant. How did they manage to grow to such sizes? Some experts believed that they grew slowly throughout their lives, others that they grew rapidly in their youth, and then the rate of increase in size slowed down, as in birds and mammals. that all these creatures were between two and 28 years old at the time of death. Animals grew the most in the 14-18th years of their lives, subsequently maintaining the achieved sizes.

Feathered Tyrannosaurus

Ancestors tyrannosaurus were covered with small feathers rather than bare skin. The skeleton of the ancestor, about 130 million years old, is the most ancient representative of the genus of tyrannosaurs, and is still the only one whose “feathering” is beyond doubt among paleontologists. It was about one and a half meters from the nose to the tip of the tail. However, it walked on its hind legs and was a formidable predator - for smaller herbivorous dinosaurs. The tyrannosaurus itself was unlikely to be covered with feathers - they would have hindered it more than helped it, due to large sizes it was more important for him to give back the world around us excess heat to avoid overheating. However, its "chicks" could hatch from eggs covered with some analogue of down, and lose it as they grow older. Slow predators

The largest predator in the dinosaur world was probably quite slow.
Tyrannosaur rex could not accelerate to a speed of more than 40 km/h, although many scientists believe that it was capable of running almost twice as fast. Scientists made their conclusions based on computer model six-ton ​​lizard.

What did tyrannosaurs eat?

The size of tyrannosaurs posed problems for these animals - as they became larger, they most likely gradually lost the ability to move quickly. Young small animals could reach speeds of up to 40 kilometers per hour, but as soon as the weight became more than a ton, this became impossible for biomechanical reasons. So if this animal was a predator and not a scavenger, it seems a mystery how it managed to obtain enough food to maintain a gigantic body growth rate. Perhaps the ecosystem Jurassic produced enough carrion - and the tyrannosaurs simply did not need to actively hunt. There was plenty of carrion around. It is still unclear whether tyrannosaurs were predators, or fed primarily on carrion?

Powerful bite

The tyrannosaurus did not simply sink its teeth into the body of the victim, as, say, lions do today. He quickly and easily bit through muscles, cartilage and even thick bones to great depths, and then tore large pieces of flesh out of the victim. The ground bones were eaten along with the meat. Tyrannosaurus had a very strong skull and jaw. And the most amazing thing is that the monster also had the whole system shock absorption. In particular, unlike most animals, part of the bones that make up the skull of the tyrannosaurus retained some mobility relative to each other. Connective tissues helped dissipate the impact energy. Of course, this way of feeding the tyrannosaurus was also facilitated by its sharp 15-centimeter teeth.

Tyrannosaurus)

During its habitat - in the Cretaceous period, Tyrannosaurus - the "Tyrant Lizard" - was the largest terrestrial carnivore.
If we compare everyone known to science, then Tyrannosaurus is the fourth longest among carnivorous dinosaurs, second only to the carnivorous dinosaurs of the mid-Cretaceous period - Spinosaurus, Giganotosaurus and Carcharodontosaurus.
More than 30 finds of tyrannosaurs have been described, all of them belong to formations approximately 68-65 million years old.
Paleontologist Robert T. Bakker of the Wyoming Museum called Tyrannosaurus "the 10,000-foot marathon runner from hell," in tribute to its size, ferocity and power.
Scientists are particularly fascinated by the monster’s teeth: some researchers compare them to railroad spikes, and Kevin Padian from the University of California figuratively called these sharp 18-centimeter daggers “deadly bananas.”
In fact, in their shape and size, Tyrannosaurus's teeth resemble very large bananas.

But despite such a powerful “weapon” of the lizard, many scientists believed that the Tyrannosaurus was not a predator, but an ordinary scavenger. Back in 1917, Canadian paleontologist Lawrence Lamb suggested that these were peculiar land vultures.

Supporters of the scavenger lizard appealed to the “weak teeth theory,” which was based on the fact that the elongated teeth of Tyrannosaurus rex could not withstand impacts on the bones of victims and were adapted only for snatching huge pieces of half-decomposed meat.

In addition, they also argued that the dinosaur's small arms did not contribute to its deadly attacks, and the Tyrannosaurus was quite slow to pursue prey.
Proponents of the idea that Tyrannosaurus was a carnivorous predator argued that the lizard’s teeth were quite strong, and its “little hands” could lift about 180 kg.
Some scientists even claim that there was not and is not a single animal that can compare with the tyrannosaurus in strength...
As for the speed of movement of the lizard, there is an opinion that, according to data based on the proportions of the limbs of the Tyrannosaurus, it could reach 47 km per hour (some scientists claim even 72 km/h or more)!
(discussion of Tyrannosaurus's speed abilities...)

Now most scientists are sure that the Tyrannosaurus was still a predator and enough evidence has been found for this.
Firstly, large number marks of Tyrannosaurus teeth, which were found on the bones of herbivorous dinosaurs; secondly, paleontologists found crushed bones of these same harmless lizards in the famous Tyrannosaurus coprolite sample - a fossilized excrement of a monster measuring 44 by 16 by 13 cm.
The remains of the world's largest Tyrannosaurus were discovered in August 1990 on the territory of the Maurice Williams ranch in South Dakota (USA).
Sue, as the dinosaur was named after the paleontologist Sue Hendrickson who discovered it, reached a height of 4 meters, a length of 12 meters, and weighed almost 8 tons!
And the length of the toothy skull of the giant lizard was 1.5 meters.
But what made Tyrannosaurus Sue famous not only was its size, but almost detective story associated with his remains...
The leader of the team of paleontologists from the Black Hills Institute of Geological Research, which included Sue Hendrickson, Peter Larson, wrote the farmer a check for $5,000 for excavations at the Williams ranch and the fossils discovered there.
After this, the found remains of the Tyrannosaurus were sent to the institute, where Larson intended to dissect them, study them and assemble a skeleton from them. While studying the Tyrannosaurus rex remains, Larson began giving public lectures and writing popular articles about Sue.
Literally, crowds of tourists began to arrive at the institute to look at the now famous lizard.
With all this, very specific visitors began to visit the institute - agents of the FBI and national law enforcement agencies. The remains of Sue's Tyrannosaurus and other fossils were confiscated, as were photographs, recordings and business documentation.

The thing is that it turned out that the land in which Sue was discovered was under the jurisdiction of the government, so the deal with the farmer was illegal...
In 1993, a U.S. grand jury indicted Larson and five of his colleagues on 39 counts, including theft of fossils from public lands. It turned out that Larson did not have the right to excavate and buy fossils without permission from the US Department.
The Black Hills Institute's counterclaim for the return of Sue's Tyrannosaurus Rex skeleton was rejected...
The story ended with Sue's remains being sold at Sotheby's in 1997. Bidding started at $500,000, and by the end of the auction the price had risen to $8.36 million.
The dinosaur was bought by a museum in Chicago, which was helped to raise such an astronomical amount by numerous sponsors. Many paleontologists are concerned about this precedent for selling a fossil at auction, because it was possible that Sue would have been bought by some rich exotic lover and famous lizard at long time, if not forever, would disappear from the field of view of scientists.
It was initially believed that Tyrannosaurus was a solitary, ruthless predator, but over time, evidence has accumulated that these dinosaurs hunted in packs.

The thing is that the remains of Tyrannosaurs are often found together: such a massive death of animals is possible if they hunt in a pack and the animals, one after another, fall into a trap (swamp bog, mud spring, quicksand) in pursuit of prey.
For example, in Alberta (Canada) in 1910, 9 Tyrannosaurs were discovered in one place. The lizards in this dead flock were from 4 to 9 meters in length, which indicates a different age of the animals.
One more interesting feature Tyrannosaurus - judging by the structure of the pelvic bones and the number of tail chevrons, females were larger than males, like crocodiles or some birds of prey.
Tyrannosaurs also fought with each other. Most likely, they fought for leadership in the pack or divided females and territory. Researchers have found traces of Tyrannosaurus teeth on the bones of their relatives, especially young ones.
One lizard even carried a “souvenir” tooth stuck in its jaw from its fellow.
It is possible that these dinosaurs even ate their relatives, but still their main prey were herbivorous dinosaurs.
Recent studies of proteins found in a Tyrannosaurus rex femoral fossil have shown the dinosaurs' closeness to birds. Tyrannosaurus is descended from small carnivorous dinosaurs from the late Jurassic era, not from carnosaurs. The currently known small ancestors of Tyrannosaurus (for example, Dilong from the Early Cretaceous of China) were feathered with thin hair-like feathers.
Tyrannosaurus itself may not have had feathers (known skin prints from the thigh of Tyrannosaurus bear the typical dinosaur pattern of polygonal scales).
In 1988, employees of the Botanical Institute named after. Komarova RAS, in Chukotka on the river. Kakanaut the remains of Tyrannosaurus rex bones were discovered. These are the first discoveries of dinosaurs located beyond the Arctic Circle.

The tyrannosaurus had a very acute sense of smell, more acute than that of a dog, and it could smell blood from several kilometers away.
The maximum opening of the powerful jaws of the tyrannosaurus reached 1.5 m.
Tyrannosaurus marked its territory the way modern felines do and never left it.
Thanks to the pads in its paws, the tyrannosaurus felt the slightest vibration of the earth. Sound waves were transmitted through the pads to the paws, then up the skeleton and reached the inner ear.
Thus, the tyrannosaurus felt what was happening around.

In the “Reptiles and Amphibians” section, for the first time we decided to talk about such an animal, which previously, undoubtedly, was the king of beasts, if you can call it that. To begin with, we will find out what tyrrhanosaurus means in translation from Latin, let's name the closest relatives of this predator. Then we’ll talk more about his appearance and size. Of course, the article about the Tyrrhanosaurus would not be complete if we did not tell who it hunted, where and when it lived on Earth.

Tyrannosaurus Rex is one of the most famous carnivorous dinosaurs. Even a modern lion cannot compare with him. It owes part of its popularity to the means mass media, especially the release of the film “Jurassic Park”. At the American Museum of Natural History in New York, it is a favorite exhibit among visitors.

The meaning of the name Tyrannosaurus and its closest relatives

Tyrannosaurus - literally translated from Latin as “tyrant lizard”. This name comes from the ancient Greek words - “tyrant” and - “lizard, lizard”. Rex means "king". This was the name and first description of this dinosaur in 1905 by the famous American biologist and paleontologist Henry Fairfield Osborne, who was president at the time. American Museum Natural History in New York.

The Tyrannosaurus genus belongs to the Tyrannosauridae family and consists of only one species of animals - Tyrannosaurus Rex - a large carnivorous dinosaur. In addition to it, Tyrrhanosaurus includes another subfamily, which includes Albertosaurus, Alectrosaurus, Alioram, Chingkankousaurus, Daspletosaurus, Eotyrannus, Gorgosaurus, Nanotyrannus and Tarbosaurus.

Dimensions, appearance and structural features of Tirex

The largest and most complete T-Rex skeleton ever found was named Sue, after its discoverer, paleontologist Sue Hendrickson. After carefully measuring Sue's bones, scientists concluded that T-Rex was one of the largest predatory dinosaurs. It was up to 4 meters (13 ft) high and 12.3 m (40 ft) long. Sue's recent analysis, published in 2011 in the journal PLoS ONE, suggests that Tyrrhanosaurus weighed as much as 9 tons (8,160 kg to be exact).

T-Rex had powerful thighs and a long, strong tail., who served not only deadly weapon, but primarily as a counterweight to it big head(Sue's skull is 1.5 m, or 5 feet long) and allowed the dinosaur to move quickly. In 2011, studies were conducted that were able to model the distribution muscle tissue based on the skeleton of a lizard. According to the results obtained, it can be assumed that this predatory dinosaur could reach speeds of 17 to 40 km/h (10–25 mph).

The two-toed front paws were so insignificant that it becomes very unlikely that T. rex could have used them for hunting or with their help to bring food to the mouth. "We don't know why it needed those little paws," University of Kansas paleontologist David Burnham said honestly.

Tyrannosaurus has the strongest bites of any animal

A 2011 study of T. Rex's massive skull, published in the journal Biology Letter, found that the dinosaur's bite could be considered the most powerful bite of any animal that has ever lived on Earth. These figures reached an impressive figure of 12,814 lbf (57,000 Newtons).

T-Rex had the strongest and sharpest teeth, the largest of which reached 12 inches in length. But according to a 2012 study published in the journal Earth Sciences, not all teeth served the same function. In particular, the dinosaur grabbed food with its front teeth, the side teeth tore it into pieces, and the back teeth ground it and sent pieces of food further along the digestive tract. It should be noted that the front teeth were flat and fit much more tightly together than the side teeth. This eliminated the possibility of breaking a tooth during the capture of the victim, when she was still trying to resist and escape.

Who did Tyrannosaurus hunt?

It is a huge predator that primarily preyed on herbivorous dinosaurs, including Edmontosaurus and Triceratops. "By constantly hunting, this predator consumed hundreds of pounds of meat over the course of its life," Burnham said.

"It's possible that the T-Rex shared its catch, but did so reluctantly," Burnham said. “He had a hard life, he was constantly hungry and so he hunted all the time.” Note: dragonflies also have to hunt all the time, you can read about this in the article about dragonflies.

“Over the years, evidence has been collected that The main occupation of Tyrrhanosaurus was hunting for food. All of them were indirect and were based only on bite marks, on fallen teeth found near the remains of other dinosaurs, as well as the presence of traces and even whole hunting trails Tyrannosaurus,” Burnham said. But in 2013, in the official journal Proceedings of the National Academy of Sciences, Burnham and his colleagues finally presented direct evidence of the predatory nature of T. rex. They discovered a Tyrannosaurus rex tooth stuck between the tail vertebrae of a duck-billed dinosaur. Moreover, the victim managed to get away from the T-Rex, and over time, this wound with the tooth healed.

"We found the smoking gun!" says Burnham. “Thanks to this discovery, we now know for sure that the monster in our dreams really existed.”

The journal PLoS ONE published in 2010 the results of analyzes of deep bites and cuts obtained from the teeth of a Tyrannosaurus rex. Yet it is unclear whether Tyrannosaurs were prone to cannibalism, fighting to the death with other relatives, or simply eating their remains.

Scientists are confident that Tyrannosaurs hunted both alone and together with other dinosaurs. In 2014, footprints were discovered in the Rocky Mountains of British Columbia that belonged to three dinosaurs from the Tyrannosauridae family. Presumably these were Albertosaurus, Gorgosaurus and Daspletosaurus. A study published in the journal PLoS ONE found that at least relatives of T. rex hunted in packs.

In what places and at what time did T-rex live?

Dinosaur fossils can be found in various rocks, belonging to the Maastrichtian stage of the Late Cretaceous period, which was about 65-67 million years ago, at the end Mesozoic era. Tyrannosaurus was one of the last dinosaurs to did not evolve into birds, and lived until the Cretaceous-Paleogene extinction, during which the dinosaurs disappeared.

Tyrannosaurus Rex, unlike other land dinosaurs, constantly roamed throughout the western part North America, which at that time was huge island- Laramidia. According to National Geographic, more than 50 T-Rex skeletons have been discovered, some of them very well preserved. Even remnants of skin and muscles are visible on them.

Fossil hunter Barnum Brown discovered the first partial skeleton of Tyrannosaurus rex at Hell Creek (Montana) in 1902 and after some time sold it to the Carnegie Museum of Natural History in Pittsburgh. Other Tyrannosaurus remains are at the American Museum of Natural History in New York.

In 2007, scientists discovered a T. rex footprint in Hell Creek and published the discovery in the journal Palaios. But if this print really belongs to a Tyrannosaurus, then it will be the second one that paleontologists have found. The first trace was discovered in 1993 in New Mexico.

T-Rex ( Tyrannosaurus Rex) is by far the most popular dinosaur that lived on our planet. He became the hero of a huge number of books, films, television shows and even video games.

For a very long time, T. rex was considered the most powerful carnivore that ever walked the Earth.

10 Little-Known Facts About T-Rex

1. Tyrannosaurus Rex Wasn't the Largest Carnivorous Dinosaur

Most people subconsciously believe that the North American Tyrannosaurus Rex, measuring 12 meters from head to tail and weighing up to 9 tons, was the largest carnivorous dinosaur that ever walked the planet. However interesting fact is that in ancient times there were two types of dinosaurs that were larger than T. rex - the South American Giganotosaurus, which weighed about nine tons and grew up to 14 meters long, and the North African Spinosaurus, which weighed more than 10 tons. Unfortunately, these theropods never had the opportunity to fight among themselves, since they lived in different times and in different lands, they were separated by thousands of miles and millions of years.

2. T-Rex's front legs weren't as tiny as many people assume.

One anatomical feature of Tyrannosaurus Rex that many people scoff at is its front legs, which appear disproportionately tiny compared to the rest of its massive body. But in fact, T. rex's front legs were more than 1 meter long and may have been capable of lifting up to 200 kg.

You will be interested to know that the most cartoonish - tiny front legs belong to the giant Carnotaurus. His arms looked like tiny bumps.

3. T-Rex had very bad breath.

Of course, most dinosaurs of the Mesozoic era did not have the ability to brush their teeth, and very few of them had teeth. Some experts believe that the remains of rotten meat, infected with bacteria, which were constantly present between the terrible teeth, made the T. rex bite poisonous. Such a bite would infect (and ultimately kill) the bitten victim. The problem is that this process would likely take days or weeks.

4. Female T-Rexes were larger than males.

We don't know for sure yet, but there is good reason to believe (based on the size of T. rex fossils found and the shape of their hips) that female T. rex outsized their males by 800 kg, which is a sign of sexual dimorphism.

For what? Most probable cause is that females of the species had to lay huge eggs, which is why evolution gave females such large hips, or perhaps females were simply more experienced hunters than males (as is the case with modern lions) and consumed more food.

5. The average lifespan of a T-Rex was about 30 years.

It is difficult to infer the lifespan of dinosaurs from their fossilized remains, but based on analysis of skeletal specimens found, paleontologists suggest that Tyrannosaurus Rex may have lived for up to 30 years. Since this dinosaur was on top food chain of its range, most likely its death occurred from old age, disease or hunger, and not from fights with predators. It was very rare for a tyrannosaurus to die from the teeth of another predator when it was too young and weak. (By the way, in parallel with T. Rex, Titanosaurs may have lived, whose weight exceeded 50 tons, their life expectancy was about 100 years!)

6. T-Rex hunted and picked up carrion

For years, paleontologists debated whether T. rex was brutal killer, or a banal scavenger, that is, did he actively hunt, or pick up the carcasses of dinosaurs that died of old age or disease? Today these contradictions seem quite strange, since Tyrannosaurus Rex could use these two methods of food simultaneously, like any massive predatory animal that constantly wanted to satisfy its hunger.

7. T. rex subspecies Hatchlings may have been covered in feathers

We all know that dinosaurs are the ancestors of birds, and that some carnivorous dinosaurs(especially predators) were covered with feathers. Consequently, some paleontologists believe that all tyrannosaurs, including T. rex, must have been covered in feathers at some point in their history. life cycle, most likely when they first hatched from their eggs. This conclusion is supported by the discovery of feathered Asian tyrannosaurs such as Dilong and the nearly equal T. rex Yutyrannus.

8. Tyrannosaurus Rex, most of all loved to hunt Triceratops

If you think that Mayweather vs. Pacquiao was the most brutal boxing fight, then you are sorely mistaken. Imagine a hungry eight-ton Tyrannosaurus Rex attacking a five-ton Triceratops! Such an unthinkable fight could certainly have happened, since both of these dinosaurs lived in the late Cretaceous period in the lands of North America. Of course, the average T. Rex would prefer to take care of a sick or recently hatched Triceratops. But if he was too hungry, large individuals also became his victims.

Back in 1996, a team of scientists from Stanford University who studied the skull of this dinosaur determined that T. rex bit its prey with a force of 700 to 1400 kg. per square inch, with the same force that the largest modern alligators bite. More detailed studies of the skulls showed that its bite force was in the range of 2,300 kilograms per square inch. (By comparison, the average adult can bite with about 80 lbs. per inch of force.) The powerful jaws of T. Rex could even bite through the horns of Ceratopsus itself!

10. Tyrannosaurus Rex was originally named Manospondylus

When famed paleontologist Edward Pinker Cope unearthed the first fossilized skeleton of T. rex, in 1892, he called the find "Manospondylus gigax - Greek" (giant slender vertebrae). After further impressive fossil exploration, it was then-president of the American Museum of Natural History, Henry Fairfield Osborne, who gave the immortal name Tyrannosaurus Rex, the "tyrant lizard king."

Tyrannosaurus was one of the largest land predators in the history of civilization, had excellent binocular vision and a well-developed sense of smell. Mighty sharp teeth, like giant scissors, tore apart the prey and crushed the bones (not very large) of herbivorous dinosaurs. Such a heavyweight was not a sprinter - he often ate carrion, and the younger generation actively pursued and caught up with prey.

For the first time, a tyrannosaurus, or rather its skeleton, was discovered in 1902 in the USA.

The reptile walked on two legs, had tiny, short, two-fingered forelimbs and had huge jaws.

The word "tyrannosaurus" itself comes from two Greek words "tyrant" and "lizard".

It has not been conclusively established whether tyrannosaurs were predators or whether they ate carrion.
Tyrannosaurs are scavengers. One of the paleontologists American expert Jack Horner argues that tyrannosaurs were purely scavengers and did not take part in hunting at all. His hypothesis is based on the following statements:
tyrannosaurs had large (relative to brain size) olfactory receptors, suggesting a well-developed sense of smell, which presumably served to detect rotting remains over vast distances;
powerful teeth, each 18 cm long, make it possible to crush bones, which is required not so much for killing as for extracting as much food as possible from what remains of the carcass, including bone marrow;
If we accept that tyrannosaurs walked and did not run (see below), and their prey moved much faster than them, then this can serve as evidence in favor of feeding on carrion.

Tyrannosaurs were brutal, aggressive killer predators.

There is evidence in favor of the predatory lifestyle of the tyrannosaurus:
the eye sockets are located in such a way that the eyes could look forward, providing the tyrannosaurus with binocular vision (allowing it to accurately judge distances), which is primarily required by the predator (although there are many exceptions);
bite marks on other animals and even other tyrannosaurs;
the comparative rarity of finds of tyrannosaurus remains, in any ecosystem the number large predators significantly fewer of their victims.

Interesting facts:

While studying one of the tyrannosaurs, paleontologist Peter Larson discovered a healed fracture of the fibula and one vertebra, scratches on the facial bones, and a tooth from another tyrannosaurus embedded in a cervical vertebra. If the assumptions are correct, then this indicates aggressive behavior tyrannosaurs towards each other, although the motive remains unclear: whether this was competition for food/mate or an example of cannibalism.
Later studies of these wounds showed that most of them were not traumatic, but infectious, or were inflicted after death.

In addition to live prey, these giants did not disdain to eat carrion.

Many scientists believe that tyrannosaurs could have had a mixed diet, like modern lions - predators, but could eat the remains of animals killed by hyenas.
The mode of movement of the Tyrannosaurus remains a controversial issue. Some scientists are inclined to believe that they could run, reaching speeds of 40-70 km/h. Others believe that tyrannosaurs walked, not ran.
“Apparently,” writes Herbert Wells in the famous “Essays on the History of Civilization,” “tyrannosaurs moved like kangaroos, relying on a massive tail and hind legs. Some scientists even suggest that the Tyrannosaurus moved by jumping - in this case, it must have had absolutely incredible muscles. A leaping elephant would be much less impressive. Most likely, the tyrannosaurus hunted herbivorous reptiles - inhabitants of swamps. Half immersed in liquid swamp mud, he pursued his prey through the channels and pools of swampy plains, such as the present-day Norfolk swamps or the Everglades swamps in Florida.
The idea of ​​bipedal dinosaurs similar to kangaroos was widespread until the middle of the 20th century. Examination of the tracks, however, did not show the presence of tail prints. All predatory dinosaurs kept their bodies horizontal when walking, with the tail serving as a counterweight and balancer. In general, the tyrannosaurus is close in appearance to a huge running bird.
Recent studies of proteins found in a fossilized Tyrannosaurus rex femur have shown the dinosaurs' closeness to birds. Tyrannosaurus is descended from small carnivorous dinosaurs from the late Jurassic era, not from carnosaurs. The currently known small ancestors of Tyrannosaurus (for example, Dilong from the Early Cretaceous of China) were feathered with thin hair-like feathers. The Tyrannosaurus rex itself may not have had feathers (known impressions of the skin of the Tyrannosaurus rex thigh bear the typical dinosaur pattern of polygonal scales).
