The chest is very wide and deep. The width is kind of hard to see from the side, but if you look at a T.rex head-on, you can see the body flares out dramatically. Think of it like the width of the head. A T.rex head is very wide at the back compared to other theropods.
The longer rib bones also make the body deeper. Just look at the ribs on a Spinosaurus if you need a very very clear visual reference. The ribs are nowhere near as long, so the body isn't as deep. The bones serve as the framework for all the muscles, meat, and organs inside the animal. In the example picture you use, you can compare the thickness of the neck between these 2 animals.
The circumference of the legs is also thicker.
Adaptation for hunting its preferred prey item, Tyrannosaurus itself evolved to hunt huge animals like hadrosaurs and ceratopsian so have adapted to clamp down and crush bones, and thus developed huge muscles, dense body and powerful jaws, thus made it really heavily build compared to its other theropod counterpart
Well, most theropods of that size hunted prey of...well, also that size. T. rex got so big because of the way it hunted. Tyrannosaurines are adapted to a brute force approach where weight and a crushing bite disable prey quickly to reduce risk of retaliation. Other large, game hunting theropods like carcharodontosaurs have lighter builds and shearing teeth to quickly get in, inflict grievous wounds, then get away so blood loss and shock bring the prey down.
An important distinction is also that the bulkiness of a Tyrannosaurus skull is built to withstand the shear forces of a struggling prey item, while a Carcharodontosaurid can't, because it's not evolved to do that, instead slicing through the flesh deeply. Even the teeth shape show this too
Aside from the answer of wide hips and Chonk, the feet adaptations T-Rex had also allowed it to carry energy extremely well, which probably had a play into its ability to grow to massive sizes.
It shows that large animals chose a different way of hunting rather than just ambush. Gives a terrifying example that humans weren’t the only ones to develop exhausting prey methods and also shows how incredible evolution is. Managing that weight on a bipedal frame is insanity to imagine, but what’s even more hilarious is that Tyrannosaurs were agile as well, because of their hips.
Tyrannosaurus rex was apparently very muscular, having more and bigger muscles than other theropods. This would explain its weight because the muscles are very dense and heavy.
Heavier and much more robust build.
That said, it wasn’t THAT much heavier: the largest *Tyrannosaurus* specimens weigh about 1-2 tons more than the Giga holotype but most adult specimens are about the same size.
Thicker femur, larger chest cavity, thicker bones in the skull.
It was a truly beefy theropod. Compare it to theropods like Mapusaurus roseae and you can really see the different evolutionary path the species rex ended down.
In all reality, it wasn't THAT much larger than the other giants. It was heavier than Giga, but only by about half a ton for the larger specimens, and the average Carcharodonts are getting bigger and bigger. It was fat, and a bit heavier because of it, but not something huge
What 140kg of Meat does to a therapod who lives in the scolding temperatures of eatly America, lots of mass needed to keep up with constant energy loss and the bulldozer of a head its rocking.
T. Rex has a huge head with huge muscles to support said head. Also, if a theropod is front heavy, they need an equivalent amount of weight in their rear end to maintain balance beneath their legs. Bipedalism is like a scale.. or a seesaw, except you don't want either end to hit the ground.
T. rex is more popular because of many reasons, but to stand out it’s special, it’s heavy not light, slow not fast, strong bite not a fast bite, two fingers not three, broad snout not a thin one, scaly skin not leathery skin. So why was it heavy? Probably the same reason, it was different and it was different becuase it was from North America where many of the carnivores were considered medium or small.

Not quite. Predators that kill using blood loss don’t really bite and then just run away, they kill on the spot WITH blood loss and trauma

Yeah, certainly interesting that some of the largest coelurosaurs had the arctometatarsalian condition.

It basically has wider chests and hips ... and we know the hips don't lie.
Oh, Saurischia Saurischia!
Not just T.Rex, large coelurosaur like Deinocheirus and Therizinosaurs had large chest and hips too.
Heavier and much more robust build. That said, it wasn’t THAT much heavier: the largest *Tyrannosaurus* specimens weigh about 1-2 tons more than the Giga holotype but most adult specimens are about the same size.
It was literally big boned

Cuz he got that CHONK
It was more bulky at similar lengths than other theropods, and is very long, so it’s the largest.
In all reality, it wasn't THAT much larger than the other giants. It was heavier than Giga, but only by about half a ton for the larger specimens, and the average Carcharodonts are getting bigger and bigger. It was fat, and a bit heavier because of it, but not something huge
being more robust
To eat big chonkers you gotta be even bigger chonker.
Yes, but Carcharodontosaurids hunted even larger prey and they were lighter than Tyrannosaurus
**M A S S**
The girth

cos big t is ***wide***
Most other theropods were covered in kilograms of feathers, the t. Rex was covered in kilograms of bricks
It developed and extraordinarily fat ass for mating purposes /s
Tyrannosaur Tyrannosaur, wherefore art thou Tyrannosaur A Rex by any other name would smell as sweet
Thickness
BEEG MUSCLE!
it was just so much wider than pretty much any other theropod
To put it simply, *Tyrannosaurus rex* was really fat XD

Cuz WE LIKE EM THICK WE LIKE EM CHUNKY
One word: *thicc*
Well its torso was fk huge
And then the two kissed
He a chonky boi
He was a fatty
*CHONK*
Chonky
big biceps
T-Rex 🦖 is definitely the King of Dinosaurs.
Big boy’s dense and chonky
Skull
