In late 1905, newspapermen were writing excitedly about the bones of a prehistoric monster that paleontologists had unearthed in the badlands of Montana. The New York Times presented the "tyrant lizard" as the most formidable fighting animal in history. More than a hundred years have passed and Tyrannosaurus rex still excites the imagination of the public and paleontologists.

More than 12 meters from muzzle to tail, dozens of pointed teeth the size of a rail crutch: a Tyrannosaurus rex that lived 66 million years ago is not just one of prehistoric predators, but an icon of ancient horror. He is so charismatic that the routine paleontological discussion can be inflated to ugly proportions.

This happened last year when a group of paleontologists presented their views on the fact that T. rex was not so much a hunter as a scavenger. The media presented it as a sensation, which infuriated paleontologists. In fact, the issue has long been resolved: enough evidence has been collected that suggests that the dinosaur not only ran after prey, but also did not disdain carrion.

It is only discussed what role living and dead animals played in his diet. What is especially annoying, this one is not the most important problem hid other, more interesting aspects from the public.

For example, the origin of dinosaurs remains a mystery. Researchers cannot yet determine how the kings of the Cretaceous period (145-66 million years ago) grew from tiny dinosaurs of the Jurassic period (201-145 million years ago). What T. rex looked like as a young adult is heavily debated: it is suspected that some specimens described decades ago as separate species are in fact juveniles of other species.

Even the appearance of the Tyrannosaurus rex remains controversial: many argue that the giant body was covered with fluff and feathers, and not scales. The controversial question of why the animal had such a massive head and legs, but tiny forelimbs, has not gone anywhere.

Fortunately, there is enough material. “Fossils abound,” reports Stephen Brusatte of the University of Edinburgh (UK). “It is rare that so many good specimens remain from one species. With T. rex, we may wonder how it grew, what it ate, how it moved; many other dinosaurs we can't ask that."

In the first decades after Henry Fairfield Osborne named and described the rex rex, paleontologists saw it as the culmination of the growth of land carnivores. Therefore, T. rex was considered a descendant of the Allosaurus, a 9-meter predator that lived more than 80 million years earlier. Both of them, along with other carnivorous giants, were united in the taxon Carnosauria, with T. rex considered as the last and largest member of the ferocious family.

But in the 1990s, a more rigorous research method, cladistic analysis, began to be applied, and the evolutionary relationships between groups of dinosaurs were revised. It turned out that the ancestors of T. rex "a were small furry creatures that lived in the shadow of the allosaurus and other predators of the Jurassic period.

According to the new view, T. rex and its closest relatives (Tyrannosauridae) represent the top branch on a large evolutionary "bush" called Tyrannosauroidea, which arose about 165 million years ago. Among the earliest members of this group is Stokesosaurus clevelandi, a 2-3 m long bipedal predator that lived about 150 million years ago.

Little is known about this creature, but other early tyrannosauroids attest: Stokesosaurus, more likely, had a long low skull and thin forelimbs. In the Jurassic size hierarchy, early tyrannosauroids were at the very bottom. “By today's standards, they were at the level of lapdogs,” Mr. Brusatte jokes.

How did it happen that over time the tyrannosaurs were on top the food chain North America and Asia? So far, history is silent on this. A very small number of rocks aged 90-145 million years were found (it was during this period that tyrannosaurs crushed competitors), so the biodiversity of those times was reconstructed very fragmentarily. Nothing can be said about changes in sea level and climate in general, which could lead to the dominance of this particular group.

IN Lately the main attention of paleontologists studying this time interval is riveted to China. In 2009, Peter Makowitzky of the Field Museum in Chicago (USA) and his colleagues described a long-snouted Tyrannosaurus rex called Xiongguanlong baimoensis, which was found in western China in rocks formed 100-125 million years ago.

In length, the animal reached almost four meters - a solid step forward compared to the tyrannosaurs of the Jurassic period. And in 2012, Xu Xing from the Institute of Vertebrate Paleontology and Paleoanthropology (PRC) and colleagues described a 9-meter tyrannosaurus named Yutyrannus huali, which belongs to the same era.

This may have been a crucial time interval when tyrannosaurs and allosaurs fought to the death for the same ecological niches. In the rocks from the north of China, Mr. Brusatte and his colleagues found the allosaurus Shaochilong maortuensis, 5-6 m long, which lived about 90 million years ago, that is, the sizes of competitors approximately coincided. But exactly when and why the tyrannosaurs won remains unknown.
It's just not interesting to portray our hero. He must be fighting someone! (Fig. ameeeeba.)

A similar situation with how T. rex looked in his youth. At the center of the discussion is Nanotyrannus lancensis, found in the same North American deposits as T. rex, and possibly growing in length over 6 m. At first it was considered separate view, but some researchers see him as a juvenile T. rex "a.

According to Thomas Holtz, Jr. of the University of Maryland at College Park (USA), the differences between N. lancensis and T. rex resemble those between juveniles and adults of other tyrannosaur species. It should be noted that all samples of nanotyranus seem to him "minor".

Lawrence Whitmer of Ohio University (USA) does not think so. In 2010, he and his colleague Ryan Ridgley, following a CT scan of a skull from the Cleveland Museum of Natural History (H. lancensis holotype), found unusual depressions in the skull and paranasal sinuses in the back of the skull, where air sacs were located during the dinosaur's life. With these formations, this specimen is very different from T. rex "a, which makes it possible to attribute the specimen to another species.

In addition to what was said, Peter Larson, president of the Black Hills Institute of Geological Research (USA), argues that the teeth of nanotyranus have too small serrations and are too densely packed. He also points out the differences in the anatomy of the glenoid cavity of the scapula and the openings in the skull.

However, critics have noted that some of this information was gleaned from the analysis of fossils that have not yet been described in scientific literature. Moreover, scientists may even lose one of the key samples of nanotyranus, because in November it will be sold at auction in New York.

The hype has done its job: the specimen is estimated to fetch the owner $9 million. Most paleontologists simply refuse to consider fossils that are not freely available in a reputable museum. Does some private trader have the audacity to rob science?

“In the current situation, there is only one thing left - to advise again in a tired voice to look for other samples,” says Mr. Whitmer. For the nanotyrannus to be finally recognized as a separate species, either a young T. rex "a, more like an adult than a nanotyrannus, or the remains of an animal that was undoubtedly an adult nanotyrannus and clearly different from T. rex "and must be found. But Mr. Whitmer is pessimistic about the chances of stopping the discussion: "I don't know how much data is needed to convince everyone." T. rex is too charismatic, and views on it have already developed, so paleontologists will not simply abandon the usual opinion.

Another example of this is the debate about appearance our hero. From generation to generation he was depicted as covered with scales like modern reptiles although they are very distant relatives. But in the last two decades, specimens from many groups of dinosaurs with feathers and down have been discovered in China. Some of them are species closely related to T. rex.

In 2004, Mr. Xu described a small early Tyrannosaurus rex, Dilong paradoxus, with filament impressions around the tail, jaw, and other parts of the body. Is it a fluffy coat? The giant Y. huali was also feathered. The feathers of tyrannosaurus rexes were not like those of modern birds, but their primitive predecessors. According to Mr. Xu, they were primarily used for decoration, and later they were used for thermal insulation. It is possible that T. rex also proudly wore some kind of proto-feathers.

No, no one wants to say that T. rex looked like a chicken. We are talking about thin fibers, a kind of hairs - for example, on the muzzle.

Since not a single T. rex skin print has been found, all these are just assumptions, which is what skeptics use. Thomas Carr from Carthage College (USA) refers to skin prints of species close to T. rex that have not yet been described in the scientific literature " y, on which the scales are supposedly clearly visible. Well, it's entirely possible that early tyrannosauroids had feathers, but the subgroup of tyrannosaurids that includes T. rex evolved to abandon them in favor of scales.

The issue of feathers is very important not only for artists who no longer know how to depict the ancient miracle Yudo. If there were feathers, then we can assume some kind of mating games and talk about how the tyrannosaurus regulated body temperature.

Another secret is the giant's small hands. They are so short that you can't even reach your mouth with them. Paleontologists are all right with fantasy, and for a hundred years the most exotic hypotheses have been expressed: they say, it was so convenient to hug a partner during mating or climb steep slopes. Gradually, the opinion was established that the forelimbs are a rudiment. Countless cartoonists to this day depict tyrannosaurs, which on this basis are pursued by one embarrassment after another.

But Sarah Birch from Ohio University (USA) believes that such jokes are unfair. She studied the musculature of crocodiles and the only living descendants of dinosaurs, birds. If the arms of T. rex were indeed useless vestiges, they did not have any significant muscles, but the fossils retained signs that very significant muscles were attached to the bones.

So T. rex used his handles. But for what? Grabbed and held certain objects (for example, prey), as did all the other theropods?

Mr. Holz has a different idea. Estimates of muscle strength suggest that these short arms were still relatively weak tools. And since specimens with healed fractures of the forelimbs were found, the scientist concludes that they did not play vitally. important role. One thing remains: short arms could come in handy during mating games. Who knows, what if they were wrapped in multi-colored feathers? ..

Niramin - May 30th, 2016

Tyrannosaurus (a detachment of lizards, a family of tyrannosaurus) is one of the most famous dinosaurs that lived in the last era of the Cretaceous period, 68 - 65 million years ago. He was one of the largest, if not the largest among the giant lizards. The body length of these animals averaged 12 m, height - 6 m, and weight - 7 tons. Strong, sawtooth teeth, about 15 cm in size, securely held the prey. The powerful and mobile neck contrasted with the tiny forelimbs, which had two fingers each.

Scientists suggest that tyrannosaurs ate in much the same way as modern lions, that is, they hunted herbivorous representatives of the flora and did not neglect carrion. Most often, duck-billed dinosaurs became their victims. Since the latter were running fast, predators attacked them from ambush.

Zoologists have long wondered why this carnivore had such short front legs. Most believe they were used to get up after sleep.

Fossils in the form of several teeth of a tyrannosaurus rex were found back in XIX century. However, it was not possible to determine to whom they belonged. Only in 1905, when archaeologists unearthed two almost complete skeletons, did the British scientist Osborn give this species of lizards his name (Tyrannosaurus rex) and describe them.

Remains giant predators found in the USA (Montana, Texas and Wyoming), Canada (Alberta, Saskatchewan), Mongolia in Asia. In 2011, Chinese scientists discovered a Tyrannosaurus rex skeleton with feather impressions in Liaoning province and suggested that it probably belonged to a young specimen, and primitive plumage served to protect from the cold.

Tyrannosaurus rex was one of the largest land predators in the history of civilization, had excellent binocular vision and a well-developed sense of smell. With mighty sharp teeth, like giant scissors, he tore 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 United States.

The reptile moved on two legs, had tiny, short two-toed 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 fed on carrion.
Tyrannosaurs are scavengers. One of the paleontologists, American expert Jack Horner, claims that tyrannosaurs were exclusively 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, which suggests a well-developed sense of smell, which presumably served to locate rotting remains at great distances;
powerful teeth 18 cm long each allow crushing bones, which is required not so much for killing, but for extracting as much food as possible from what is left of the carcass, including bone marrow;
if we assume that tyrannosaurs walked, not ran (see below), and their prey moved much faster than them, then this can serve as evidence in favor of feeding on carrion.


Tyrannosaurus rex were brutal, aggressive predatory killers.

There is evidence in favor of the predatory lifestyle of the tyrannosaurus:
the eye sockets are arranged in such a way that the eyes can look forward, providing the Tyrannosaurus rex with binocular vision (allowing it to accurately judge distances), which is primarily required by a predator (although there are many exceptions);
bite marks on other animals and even other tyrannosaurs;
the comparative rarity of finds of the remains of tyrannosaurs, in any ecosystem the number of large predators is much less than 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 of another tyrannosaurus rex embedded in the cervical vertebrae. If the assumptions are correct, then this indicates aggressive behavior tyrannosaurs in relation to each other, although the motives remain unclear: whether this was competition for food/partner or an example of cannibalism.
Later studies of these wounds showed that most of them are not traumatic, but infectious in nature, 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, for example, modern lions - predators, but can eat the remains of animals killed by hyenas.
The mode of movement of the tyrannosaurus rex remains a controversial issue. Some scientists are inclined to the version that they could run, reaching a speed of 40-70 km / h. Others believe that tyrannosaurs walked, not ran.
“Apparently,” writes H.G. Wells in the famous Outline of the History of Civilization, “tyrannosaurs moved like kangaroos, leaning on a massive tail and hind legs. Some scientists even suggest that the Tyrannosaurus rex moved by jumping - in this case, it must have had absolutely incredible muscles. A jumping elephant would be much less impressive. Most likely, the tyrannosaurus preyed on herbivorous reptiles - the inhabitants of the swamps. Half immersed in liquid swamp mud, he pursued his victim through the channels and lakes of swampy plains, such as the current Norfolk swamps or the Everglades swamps in Florida.
The opinion about bipedal dinosaurs - similarities of kangaroos was widespread until the middle of the 20th century. Examination of the tracks, however, showed no tail prints. All carnivorous dinosaurs kept their body horizontal when walking, the tail served as a counterweight and balancer. In general, the tyrannosaurus is close in appearance to a huge running bird.
Recent studies of proteins found while examining a fossil T. rex femur have shown dinosaurs to be closely related to birds. Tyrannosaurus is descended from small carnivorous dinosaurs of the late Jurassic era, not from carnosaurs. The currently known small ancestors of Tyrannosaurus Rex (such as the dilong from the Early Cretaceous of China) were feathered with fine, hair-like feathers. The Tyrannosaurus rex itself may not have had feathers (known impressions of the skin of the thigh of a Tyrannosaurus rex bear a pattern of polygonal scales typical of dinosaurs).

Tyrannosaur Cretaceous Dinosaur. Tyrannosaur- a representative of theropod lizard dinosaurs, the infraorder of tyrannosaurids. Tyrannosaur was one of the largest land predatory lizards that ever existed on our planet. Tyrannosaur is a member of the tyrannosaurid family. Among the predators of its time, the tyrannosaurus was the largest. calling card tyrannosaurus rex is the power of his jaws. Tyrannosaur was not the largest of the theropods mesozoic era, but in terms of bite strength he had no equal.
Thanks to numerous films, tyrannosaur gained wide popularity. Maybe, tyrannosaur the most famous of the dinosaurs. His image can be seen on the advertisements of some companies or products.

Huge and powerful mouth tyrannosaur grabbed his victim and as soon as the jaw closed, the victim had no chance of salvation. Sharp Teeth Tyrannosaurus Rex were bent inward, which greatly facilitated the capture and holding of the victim. Teeth tyrannosaurus rex were the longest among all land predators. According to many scientists, the length of the teeth tyrannosaurus rex was up to 30 centimeters. mouth tyrannosaurus rex was not adapted to chewing food, so the lizard tore off and swallowed whole pieces of meat. If you look closely at the skull, you will see that the nasal olfactory lobes are large. This says that the tyrannosaurus rex sense of smell was well developed. It is highly likely that the nose of Tyrannosaurus rex was designed like the nose of modern scavenging birds, such as vultures.

Limbs and body structure of a tyrannosaurus rex:

Spine tyrannosaurus rex consists of 10 cervical, 12 thoracic, five sacral and about 40 tail vertebrae. The tail of a dinosaur is thick and heavy. With his help tyrannosaur keep balance while running. Also, the tail helped during the turn. Some of the bones of the skeleton were hollow inside, which made it possible to slightly reduce body weight without reducing the strength of the skeleton as a whole.
Tyrannosaur moved on powerful hind legs. Paws had 4 fingers with sharp claws. Three fingers were facing forward and one back. They were fastened together for stability. The fourth toe was on the back of the paw and never touched the ground. Perhaps he served to rip open the victim's flesh or to hold it. Paws tyrannosaurus rex were well developed and held the entire weight of a multi-ton predator. Until now, there are disputes about the speed with which he moved tyrannosaur. According to one version tyrannosaur could not reach speeds of more than 5-7 km / h. According to another version, tyrannosaur could reach speeds of up to 40 km / h, but could not sharply change direction. Also tyrannosaurus rex although he moved at a decent speed, but because of his size, he probably could not run for a long time.

tyrannosaurus rex paw

The forelimbs were very poorly developed. The short legs had 2 toes. And despite the fact that they ended in claws, it is unlikely tyrannosaur could use them for hunting. Most likely, they helped him maintain balance when moving.

Tyrannosaurus rex nutrition:

tyrannosaurus rex was a carnivorous predatory dinosaur, but the study of its fossilized remains does not give a clear answer about the method of obtaining food. Despite the frightening appearance, the version that tyrannosaur was a ruthless killer overtaking anything and everything. As already mentioned, his main weapon was a powerful jaw studded with large and razor-sharp teeth. But at the same time, his forelimbs were extremely poorly developed, and his body was very massive.

Version 1 - scavenger:

 There is an assumption that tyrannosaur- any character of fans of films about dinosaurs and the embodiment of uncontrollable rage, not only did not disdain the carcasses of dead dinosaurs, but also ate mainly them. This assumption is based on studies of fossilized remains. tyrannosaurus rex. American scientists who examined the remains came to the conclusion that a massive, multi-ton body hardly allowed tyrannosaurus to chase quickly fleeing prey like the lighter Allosaurus, and even more so Deinonychus and Utahraptor.
Conclusions that tyrannosaur was more of a corpse eater than a hunter based on CT scan results. Research, recovered brain tyrannosaurus rex, more precisely, its forms make it possible to learn more about its functionality and about the structural features of the "inner ear", which is responsible not only for the auditory function. Inner ear research tyrannosaurus rex showed that its structure differed from the structure of a similar organ of "dexterous hunters".
The next argument in favor of tyrannosaur was a scavenger are the results of studies of the vertebrae of the pangolin. The conclusion states that tyrannosaur had restrictions in movement and for various maneuvers and sharp turns his body was not adjusted. Also large dagger-shaped teeth tyrannosaurus rex more suitable for leisurely grinding bones. Such teeth are hardly necessary for a "cold-blooded killer" who eats fresh meat and goes on, leaving the carcass for a feast of carrion-eaters.
Modern and most likely prehistoric animals of large sizes are extremely slow. Wherein tyrannosaur due to its weight, it could severely damage or even break ribs and legs when falling. Small front paws with two fingers could hardly help in hunting. Therefore, it is very likely that the main food of the tyrannosaurus was the fallen dinosaurs.

Version 2 - hunter:

Despite the fact that the "scavenger" version has a fairly good justification, the "hunter" version is no less popular among paleontologists and is very "hyped" by the creators of films about dinosaurs. And don't forget that tyrannosaur the owner of the most powerful bite among land animals of all time. Not a single bone could withstand the bite of this giant.
Main prey tyrannosaurus rex were herbivorous torosaurs , triceratops ,anatotitans and other dinosaurs. Considering the dimensions, it can be assumed that tyrannosaur could not follow fleeing dinosaurs for long, and he had to catch up with prey in one rush. It is known that tyrannosaur possessed binocular vision and could accurately estimate and calculate the distance to the victim. More likely, tyrannosaur attacked a potential victim from an ambush. At the same time, most likely, he attacked cubs or old and weakened dinosaurs more often than adults and full strength. After all, some herbivorous dinosaurs, such as Triceratops or ankylosaurus, could not only run away, but give a serious rebuff. Groups of dinosaurs were especially good at defending themselves. A modern confirmation of this opinion is a herd of buffaloes. Even formidable lions do not always attack such large and powerful herbivores.
tyrannosaurs were loners and hunted each in their own territory, which was measured in hundreds of square kilometers. Periodically, skirmishes arose between the lizards for the territory, in which one of them possibly died. At such a moment, the lizards did not disdain the meat of their relatives.

More likely tyrannosaur, all the same, he was a hunter, but he could also eat a dead dinosaur. Also, given its size and power, tyrannosaur could take prey from other predators.


Reproduction of Tyrannosaurus Rex:

tyrannosaurs were loners, at least adults. Their hunting territories were measured in hundreds of square kilometres. The female, with a characteristic roar, called the wandering male. The process of courting a female, for a male, is not an easy task. females tyrannosaurs larger and more aggressive than males. Therefore, it took a lot of effort for the male to win her over. The best remedy for this there was a carcass of some kind of dinosaur as a treat. The mating process is not long. After that, the male leaves in search of food and other females, and the female prepares to become a mother and builds a nest in which she will lay her eggs.

A few months later, the female tyrannosaurus rex laid 10 - 15 eggs in a nest located directly on the ground. It was very risky. prowled everywhere small predators who have always been willing to eat an egg tyrannosaurus rex. Therefore, after the eggs were laid, the female did not leave the nest. For two months, the female tirelessly guarded the nest with eggs. Tyrnosaurus nest attracts small egg hunters, such as drommeosaurus. Two months later, small ones are born. tyrannosaurs. From the entire brood, 3-4 cubs are born.

Late Cretaceous the atmosphere is filled with gases that have a devastating effect on developing embryos. This is due to the great volcanic activity on earth in the late Cretaceous period. Tyrannosaurs, despite their greatness and power, are doomed to death.

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


The largest was the Tyrannosaurus rex, 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 roamed the Earth 65 million years ago was the largest land predator of all time.

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

Feathered tyrannosaurus

Ancestors tyrannosaurus rex were covered with small feathers, not bare skin. The ancestral skeleton, about 130 million years old, is the oldest representative of the genus of tyrannosaurs, and so far the only one whose "featheredness" is not in doubt among paleontologists. He was about a meter and a half from the nose to the tip of the tail. However, he walked on his hind legs and was a formidable predator - for smaller herbivorous dinosaurs. The tyrannosaurus itself was hardly covered with feathers - they would have interfered with it more than helped, because large sizes it was more important for him to give the world excess heat so as not to overheat. However, his "chicks" could hatch from eggs, covered with some kind of fluff, and lose it as they grow older Slow predators

Most large predator in the world of dinosaurs, was probably quite slow.
The Tyrannosaur rex could not reach speeds of more than 40 km/h, although many scientists believe that it was able to run almost twice as fast. Scientists made their conclusions on the basis of a computer model of a six-ton ​​lizard.

What did tyrannosaurs eat?

The size of the tyrannosaurs was a problem for these animals - becoming 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 is a mystery how it managed to get 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 fall around. It is still unclear whether the tyrannosaurs were predators, or whether they fed mainly on carrion?


powerful bite

Tyrannosaurus did not just 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 a great depth, and then pulled out large pieces of flesh from the victim. The ground bones were eaten along with the meat. Tyrannosaurus Rex had a very strong skull and jaw. And the most amazing thing is that the monster also had a whole shock absorption system. In particular, unlike most animals, some of the bones that make up the skull of the tyrannosaurus retained some mobility relative to each other. The connective tissues helped dissipate the impact energy. Of course, its sharp 15-centimeter teeth also contributed to this way of feeding the tyrannosaurus.
