Tyrannosaurus rex does not have feathers on its body, and we have found imprints of scales on Tyrannosaurus rex, proving that it has scales on its body. The reason why we think that Tyrannosaurus rex has long feathers on its body is because of the discovery of feathered feathered rex in Liaoning, China, and Peatherus rex and Tyrannosaurus rex are relatives. Feather rex and Tyrannosaurus rex both belong to the Tyrannosaurus superfamily, and the relationship between the two in the Tyrannosaurus rex family is still relatively distant, as long as you look at the body structure of the two dinosaurs, you will find that they actually do not look alike.
Paleontologists currently believe that newborn Tyrannosaurus rex cubs had long feathers, and as they aged, their feathers shed and eventually left scales.

The Tyrannosaurus rex has a structure on its head, as if it were wearing a helmet on its head, and the exact structure and thickness of this layer are not entirely certain yet;Tyrannosaurus rex actually had three fingers, and the third finger was heavily degenerated and attached to the side of the second finger, making it difficult to identify without careful observation.

Tyrannosaurus rex is the largest of the Tyrannosauridae family. The body length is about meters. The average hip height is about 4 meters.
The highest hip height can reach about meters, and the highest head height is nearly 6 meters. The average weight is about 9 tons, (the ecological average is about tons), the heaviest tons, and the head length is about about meters. The bite force is generally 90,000 Newtons to 120,000 Newtons, and the maximum end of the mouth can reach about 200,000 Newtons, and it is also the thickest carnivorous dinosaur.

Whether the Tyrannosaurus rex has feathers or not, you may refer to humans. Early humans had a lot of body hair, and there were some differences in human body hair in different regions. And Tyrannosaurus rex has existed for at least a few million years in history and is very widely distributed.
It is safe to say that Tyrannosaurus rex did not look the same, some had more feathers, some had less. For example, if we consider a Tyrannosaurus rex growing in the tropics, even if a lot of feathers will slowly fade, because it is not conducive to heat dissipation when running. And the relatively cold Tyrannosaurus rex will definitely have more feathers, because dinosaurs are not homeothermic animals, and no feathers to keep warm is equivalent to looking for death.

It's possible that the Tyrannosaurus rex is not the kind we have been molding, it is grinning with big teeth and clear mouths. It may have well-developed lips, so it may not be easy for the teeth to be seen, even when the mouth is slightly open. Referring to the Komodo dragon, because of the relationship between the lips, the teeth are originally large and sharp, and they are basically not visible, but they can be felt very much when they are bitten.

If you go to see Jurassic World, you won't know, and there are ** on the Internet, ** and real dinosaurs are basically 90% similar. Because people used Tyrannosaurus rex fossils and then built them into skeletal models. In addition, crocodiles are close relatives of dinosaurs, and some dinosaurs can be inferred from crocodiles.
Then use the computer to synthesize, and all kinds of dinosaurs will come out. Since the dinosaur is extinct, people will never know what it really looked like, so we reconstruct it with a computer based on a fossil model. The realism is the highest!
It's the same as in Jurassic World!

Tyrannosaurus rex family members had hair, not necessarily feathers, and there is no evidence of hairiness from the Tyrannosaurus rex itself. Dinosaurs are continuous everywhere within their defined domain. Wisdom is not a necessary attribute for survival.
A lot of times it's counterproductive. The main thing is that it is toothless, I quite agree, land creatures, especially large carnivores, often chew teeth, how can there be teeth leaking out of the creatures.

I really don't know, it disappeared hundreds of millions of years ago, and the only place you can see is the fossil.

Tyrannosaurus rex, also known as Rex Tyrannosaurus, lived in the Maastricht period at the end of the Cretaceous period, about 68.5 million to 65 million years ago, and was one of the last non-avian dinosaur species before the Cretaceous-Tertiary extinction event.
Tyrannosaurus rex is the largest of the Tyrannosauridae family. The body length is about meters. The average hip height is about 4 meters. The highest hip height can reach about meters, and the highest head height is nearly 6 meters. The average weight is about 9 tons, and the head length is about about meters.
The bite force of Tyrannosaurus rex is generally 90,000 Newtons to 120,000 Newtons, and the maximum end of the mouth can reach about 200,000 Newtons, and it is also the thickest carnivorous dinosaur.
In terms of physical characteristics, Tyrannosaurus rex has very small forelimbs, only 22% of the length of hind limbs, and the length of the average individual is only about 80 centimeters, compared to the huge size and hind limbs of Tyrannosaurus rex, the forelimbs appear very small, equivalent to an adult's arm.
In terms of length, most carnivorous dinosaurs can surpass Tyrannosaurus rex, including Sharkodontosaurus, Brutesaurus, Quirosaurus, and Sauronsaurus.
However, the body width, cervical vertebrae width, leg length, pelvic size, and shoulder blade size of Tyrannosaurus rex far exceeded that of almost all Allosaurus superdinosaurs such as Maprosaurus and Qui Rex, and had the largest and thickest and broadest head, cervical vertebrae, trunk, and hind limbs of Carnivorous Rex.
Carnivorous dragons and theropods of general size and body shape (such as ceratosaurus, allosaurus, spotted dragon, Yongchuansaurus, etc.) only have less than 50% of the weight of Tyrannosaurus rex, and some stout carnivorous dragons (such as Tyrannosaurus rex, Tyrannosaurus rex) have only 75%-80% of the body weight of the same body of Tyrannosaurus rex.
Among the carnivorous dinosaurs, only the brutesaurus and the qui rex could reach or approach 90% of the body mass index of the Tyrannosaurus rex.
In addition, the skeleton of Tyrannosaurus rex is also very thick, the growth cycle of Tyrannosaurus rex ends at the age of 19, and it will not exceed 21 years old at the latest, when the growth cycle of Tyrannosaurus rex ends, although Tyrannosaurus rex will continue to grow, but it will neither grow nor become taller, its skeleton will become thicker, and the overall look will be stronger.

Tyrannosaurus rex has very small forelimbs, only 22% of the length of hind limbs, and the length of the average individual is only about 80 centimeters, compared to the huge size and hind limbs of Tyrannosaurus rex, the forelimbs appear very small, equivalent to an adult's arm.
Their arms were very thin and the long skull of the baby Tyrannosaurus rex kept its forelimbs back, and the forelimbs could not reach their mouths, nor could they reach their own mouths, nor could they reach their feet, perhaps only as a balancing tool to balance their huge heads.
Judging from the shape of the skull of Tyrannosaurus rex, its upper jaw is wide and the lower jaw is narrow, and the force exerted by the upper and lower jaws is not completely opposite when biting, which is conducive to biting off the bones.
Tyrannosaurus rex's teeth were cone-shaped like bananas, which were suitable for crushing bones, while most carnivorous dinosaurs' teeth were mostly used for piercing and cutting. The structure of its skull suggests that the predatory behavior of Tyrannosaurus rex may have been different from that of most theropod dinosaurs.
In general, large carnivores choose prey that is about their size or smaller. Animals that hunt alone tend to choose prey that is about the same size or smaller than their own; Creatures that prey on groups can often prey on prey that is much larger than their own body.

1. Tyrannosaurus rex had a huge broad head and a short and thick neck; Behind him is a large, thick tail; The forelimbs are very short, with only two fingerheads, and the hindlimbs are long and stout, and they have a great ability to run.
2. Tyrannosaurus rex, also known as Rex Tyrannosaurus, was one of the last non-avian dinosaur species before the Tertiary extinction event in the Cretaceous period. The fossils are found in the United States and Canada in North America.

Tyrannosaurus rex had very small forelimbs, only 22% of the length of hind limbs, and the average individual was only about 80 centimeters long. The teeth are very thick and shaped like bananas, and one can be about 30 centimeters long. Like other dinosaurs of the Tyrannosauridae family, Tyrannosaurus rex was a bipedal, carnivorous dinosaur with a large skull and a long, heavy tail for balance.
Compared to their large, strong hind limbs, Tyrannosaurus rex forelimbs were very short, almost as long as a human arm. Tyrannosaurus rexes were long thought to have only two fingers, but a complete Tyrannosaurus fossil discovered in 2007 showed that they may have had three fingers.
Tyrannosaurus Rex Features:
The Tyrannosaurus rex is the superstar of the dinosaur world, but the Tyrannosaurus rex in the film and television is endowed with some characteristics of a living predator, it is as fast as a cheetah, roars like a lion, and likes to be alone like a tiger.
Eating habits: Tyrannosaurus rex was located at the top of the food chain in the late Cretaceous period, when a variety of dinosaurs in North America were basically its prey, and sometimes they also attacked long-necked herbivorous dinosaurs like Alamosaurus.

Pterodactyls, also known as pterosauria, are extinct reptiles with nearly 100 species. [1] Although at the same time as dinosaurs survived, pterosaurs were not dinosaurs. [2] The Greek word for "winged lizard" is an evolutionary branch of flying reptiles. >>>More
In the 80s of the last century, on the 515th train from Jinan to Xuzhou, I saw a crew member, and I am still deeply impressed. The 515 train is a slow train, stopping at both large and small stations, and it takes nearly three hours to travel 300 miles from Jinan to Yanzhou, which is really annoying. At that time, I met a beautiful flight attendant in Box Nine, and she reminded passengers in advance every time she arrived at the station: >>>More
The daughter of the boss of our unit, five years old this year, is a particularly cute girl, especially likes to chat with us, and one of the funniest things in my memory is that once after eating in the cafeteria, I sat on the threshold, but she ran over and whispered in my ear, uncle, you are the most handsome boy I have ever seen, I was happy for a long time. But soon after I asked her to play with her, she kept avoiding me, and then I was depressed again, but one day I stopped her and asked her why she ignored me, and she said that you are too ugly, my mother won't let me play with you!
ThatA plant with black fruitsIt's nightshade, do you know it? In our Guangxi, there are really a lot of nightshade grass, and the old evil found that there is nightshade in the orchard of the villageThe fruit is green when it is not ripe, round and resembles a wild grape, and turns black when it ripens in autumn. The appearance of nightshade is not as amazing as everyone thinks, it is just a grass, it is one of the more common traditional Chinese medicine in rural areas, and by looking at its fruit, we can quickly recognize this traditional Chinese medicine. >>>More
