霸王龙简介

Tyrannosaurus Rex (Tyrannosaurus Rex), Tyrannosaurus Rex

is the largest body. Body length of about 11.5-14.7 meters. The

average hip height is about 4 meters. The highest hip height up

to 5.2 meters, the highest height of nearly 6 meters. Average

weight of about 9 tons, (ecological average of about 7.6 tons),

the most important 14.85 tons, the head length of about 1.55

meters. Bite force is generally 90,000 Newton -12 million

Newtons, the mouth of the end of up to about 20 million

Newtons, but also the most sturdy carnivorous dinosaurs.

Tyrannosaurus reign in the ancient Greek meaning "cruel

lizard king", species name in Latin meaning king. Some scientists

believe that the Tarbosaurus bataar in Asia is the first effective

species of Tyrannosaurus rex, while other scientists believe that

tyrannosaurus is an independent genus. In addition there are

many species of Tyrannosaurus have been raised, but they are

mostly considered Tyrannosaurus synonyms, or are classified in

other genera.

Tyrannosaurusus survived the late Cretaceous Maastricht

stage (MAA) from about 68.5 million to 65 million years of the

Cretaceous period, the Cretaceous - Tertiary extinction before the

last non-bird One of the dinosaur species. Fossils distributed in

North America, the United States and Canada, is one of the latest

extinct dinosaurs.

霸王龙物种发现 In 1902, a dinosaur fossil collector in the United States,

Barnam Brown, found a giant carnivorous bones in the Black

River in Montana, where he was a staff member of the National

Museum of History. After two summers, he followed the skeleton

from the hard sandstone. As the bones were so heavy, he made

a special sled with horses, which brought the bones to the nearby

roads. What he found was the first skeleton of Tyrannosaurus rex.

In 1910, Barnum Brown led the expedition team in the

Canadian Alberta territory of the Red Deer River Canyon began a

large-scale collection. Brown found there to protect the very

good halberd dragon, helmet dragon and sharp corners and

other skeletal fossils and some dinosaur skin fossils.

In the New York Museum, Brown's boss, Osborne, could not

wait to name him the animal of Tyrannosaurus rex, while Brown

and Osborne were reshaping Tyrannosaurus rex, but they could

not The weight of two tons of bones into their minds of the image

- "smart birds such as beasts," they had to combine him into an

upright and slow appearance.

December 25, 2013, British and Australian researchers said in

Australia found a Tyrannosaurus dragon fossil, there is evidence

that Tyrannosaurus rex has also lived in the southern hemisphere

on the continent.

Researchers in the latest issue of the United States, "Science"

magazine reported that the fossil is very special, convinced that

Tyrannosaurus rex. It is about 30 cm long and unearthed in the

southeastern Australian dinosaur bay, shaped like a two ends of

the expansion of the rod, one end of the flat, the other end was

boots.

The genus of this fossil has been temporarily named NMV

P186069. Researchers speculate that the owner of the body between 6.5-7.2 meters, weighing about 5.9 tons, while the

general Tyrannosaurus long body length of more than 12 meters,

the weight can be more than 9 tons. Although the head is very

different, but both are huge head, forelimb degeneration, hind

legs developed.

霸王龙外形特征

forelimb

Like other Tyrannosaurus, Tyrannosaurus rex has a very small

forelimb, only 22% of the length of the hind legs, the general

length of only about 80 cm, relative Tyrannosaurus rex huge size

and hind legs, the forelimb is very small, the equivalent of a Adult

arm. Their arms are very thin and small Tyrannosaurus long skull

so that its forelimb position also rely on the front of the forelimb

extension of its mouth, but also can not touch their mouth, the

same more can not touch to their own Feet, it may only be the

role of balance tools only, to balance their huge head.

Head

From the shape of the skull of Tyrannosaurus rex, the

maxillary width of the mandibular narrow, occlusal when the

force applied on the mandibular teeth is not completely relative,

is conducive to bite the bones. Tyrannosaurus rexed into a cone

like a banana, suitable for crushing the bones, and most of the

meat dinosaur teeth are used for puncture and cutting. Its skull

structure shows Tyrannosaurus rex predatory behavior and most

of the dinosaurs may not be the same.

In general, large carnivores will choose their own body or

smaller prey. Individual hunting animals tend to choose their own

body with a considerable or smaller prey; groups predatory

creatures can often hunt than their own body much more prey.

New papers in 2014 show that adult tyrants of different individual bite force between 100,000 Newton to 200,000 Newton between

the average individual bite force of about 10 tons +.

Size

From the length of view, most of the carnivorous dinosaurs

can be more than Tyrannosaurus rex, including shark teeth

dragon, pretty dragon, Quebec, Solon Long, but Tyrannosaurus

long body width, cervical width, leg length, pelvic size, Far more

than the Ma Pulong and Quebec Zhou and almost all the special

dragon super dinosaurs, and has a carnivorous dragon and the

most sturdy and broad head, cervical, trunk and hind legs, the

general body and shape of carnivores and animals Foot suborder

(such as angular nose dragon, special dragon, spotted dragon,

Yongchuan Long, etc.) only Tyrannosaurus rex less than 50% of

the weight, and some stout carnivorous dragon (such as special

tyrant, burst dragon) only The same body long Tyrannosaurus rex

75% -80% body weight. Compared with the Tyrannosaurus

Branch shark teeth dragon members although in the length has

a slight advantage, but in the body of the degree of sturdy but

can not be compared with the Tyrannosaurus class, for example,

shark teeth and dragon beast in the body are close to

Tyrannosaurus rex, but In the weight and height is not

comparable to Tyrannosaurus rex. Carnivorous dinosaurs only

half of the dragon and Quebec in the body mass index can reach

or close to Tyrannosaurus 90%. Tyrannosaurus rex is also very

heavy, although the reptile as long as the immortality will

continue to grow, but this does not mean that the reptile will

become longer and longer, Tyrannosaurus Wang's growth cycle

to 19 years of age, no later than 21 Age, after the end of the

growth cycle of Tyrannosaurus rex, although Tyrannosaurus rex

will continue to grow, but it will neither long nor will become high, its skeleton will become more stout, the overall look will be more

robust. This is why the 28-year-old "Su" only 12.2 meters, but it

can and 14 meters above the level of mor1126, ucmp137538 and

other competitions have been found in the position of the largest

Tyrannosaurus rex.

Feathers

In 2004, the scientific journal "Nature" published a study that

describes an early Tyrannosaurus supernatural species, exotic

dragon, fossils found in China's Yixian group. As many dinosaurs

found in the Yixian group, Emperor's body has a layer of cover, is

considered a kind of original feathers. Also found a larger body

Tyrannosaurus long feathers, such as gorgeous feather wang

dragon. Tyrannosaurus Rexroth with other Tyrannosaurus Rex is

also presumed to have similar primitive feathers. But the adult

Tyrannosaurus fossils found in Canada and Mongolia have rare

skin traces consisting of typical pebble scales. It is also possible

that some parts of the body of the young body cover the original

feathers of the body, but after the fall, the body lacks the

segregation, as many modern large mammals, such as elephants,

hippos, and most rhinoceros. According to Holland's law,

compared with the body size, large animals, but have a smaller

proportion of the surface area, they release the heat temperature

is higher, and absorb the heat temperature is low; so the growth

of Tyrannosaurus more easy to keep the body heat The Large

animals evolved from a warm environment, and the feathers used

to isolate heat will leave excess calories in the body, causing

overheating. Thus large Tyrannosaurus dinosaurs, such as

Tyrannosaurus rex, may lose their original feathers during the

evolution to accommodate the warmer Cretaceous climate.

Sexuality With the increase in specimens, scientists began to notice the

changes between Tyrannosaurus and found that they can be

divided into two modes or forms, similar to some other beast

subordinate dinosaurs. One of the more stout, while the other is

more slender. Several morphological studies suggest that these

two forms represent tyrannosaurus with both sexes, while

relatively stout forms are usually considered female individuals.

For example, the pellets of several coarse specimens seem wide

and may be used to accommodate spawning channels. The first

section of the sturdy form of the skeleton of the human bone

narrowed, obviously used to accommodate the reproductive

system of the birth canal, which features also appear in the

crocodile body.

In recent years, evidence of both sexes has been weakened.

A 2005 study found that the original claim that the crocodile's

character-shaped bone is characterized by a heterosexual feature

that is wrong, making a similar character of the Tyrannosaurus

class sex controversy. "Sue" of the first section of the caudal

vertebrae has a full size of the chevron-shaped bone, and "Su" is

a very stout individual, showing that this feature can not be used

to identify these two forms. Because the Tyrannosaurus

specimens were found in the area of Sarkozy to New Mexico, the

differences between individuals may be more suitable for

showing geographical differences than for both sexes. These

differences may also be age-related, and the stout individual may

be older individuals.

Now only one Tyrannosaurus rex is considered to belong to

a certain sex. "B-Rex" specimens of several bones preserved soft

tissue. Some tissues are identified as medullary tissue, medullary

tissue is a species that exists only in the birds, is the source of calcium, can be made in the egg yard. Because only the female

individual spawning, medulla only exists in the female bird body;

but in the female individual manufacturing hormones such as

estrogen during the male individual also has the ability to

manufacture medulla tissue. This evidence clearly shows that "B-Rex" is a female individual and died during spawning. Recent

studies have shown that crocodiles do not have medullary tissue,

and birds and animal foot dinosaurs have a medullary tissue, and

further evidence of the evolution between the two.

Feeding habits

Tyrannosaurus rex is located in the late Cretaceous food

chain at the top, when all kinds of dinosaurs in North America

can basically be the object of their hunting, and sometimes they

will attack such as longan grass dinosaur dinosaurs. Swollen head

dragon because of the smaller size is generally not in the

Tyrannosaurus rex in the recipe. A dragon is rarely prey on

Tyrannosaurus rex. At that time distributed in North America,

some other meat dinosaurs such as dwarf Tyrannosaurus and

may have some competition with Tyrannosaurus rex, but far from

the opponent of Tyrannosaurus rex.
