Giganotosaurus carolinii vs Tyrannosaurus rex

Being longer or taller really isn't any advantage when for both it is exceedingly negligible. this comes out to roughly being a 50/50.

On a side note, the largest theropods are ~4m tall at the top of the hips. ~6-8m that is often given as a height figure are not accurate

Something that many people seem to take for granted when it comes to T-Rex's bite is that you can't just say that it would instantly kill anything that entered its mouth. For example, a Nile Crocodile is known for exerting upwards of 3,000 lbs of bite force. However, not every time that it latches to the neck of a wildebeast does it end up being killed, let alone even has its entire neck and vertebra crushed. These two animals are not close to being comparable in size.

Given that information, the highest bite force given to T-Rex by any credible resource is about 13,000 lbs, averaging around 8,000-10,000. Now, the size difference between a T-Rex and a Giganotosaurus is MUCH closer than the difference between a crocodile and a wildebeast, so why would it be easy for anybody to say that just because T-Rex has a strong bite means that it will instantly end the life of something that close to the same size, let alone something with a neck with a huge amount of muscle and a vertebra as thick as a telephone pole?

To take away more credibility from that claim would be that is that again with the size of Giganotosaurus's neck, T-Rex would have to open its mouth most of the way to even get its neck in it (I'll elaborate on the reason I mention this later). The maximum bite force of any animal is measured from one point within the jaw (Always the back, watch a video of animals getting bite force measured and you'll see this). This is because maximum bite pressure is always at the furthest back part of the jaw at one single area on one side, not the whole thing. With this being said and to finally explain the point made earlier, the T-Rex having its mouth open perhaps all the way to get the Giga's neck into it means that the back part of the mouth is not able to apply it's full amount of pressure with the tip of both the T-Rex's maxilla and mandible preventing it from doing because they arent able to meet. Plus, like I've already stated, total bite pressure is measured from one single point of an animal's mouth on a single side, so that means all of that 7,500-13,000 lbs is drastically lowered when the entire mouth is applied. It's like say having a 100 hp engine in a go-cart vs a 100 hp engine in a 2 ton car. The go-cart is going to be outrageously powerful while the car is going to be outrageously weak (the go-cart being the area where you measure maximum bite pressure and the car being the entire mouth). 

To add to this, the fact that the Rex's mouth would have to be open damn near all the way also detrimentally takes away leverage for it to inflict maximum damage. For instance, take a baby carrot and bite it in half. Pretty simple, huh? Now take a full grown carrot, of course has the same density and toughness of a baby carrot, and try to bite the fat end off. You have your mouth open almost all the way and you try your hardest but you only end up failing because your jaw strength only gets stronger as the space between them gets smaller, with your jaw being at its weakest at full gape.

which parts you do not agree?

Thanks s-rex for the informations anyways

Not a prob bruh, it's a kind of topic that isn't really brought up much anymore (dinosaur vs dinosaur), so it is certainly a pleasure. I'm arguing in contrast to the "anything that enters a T-Rex's mouth is dead meat" bit.

T.rex wins this fight

Well maybe the size comparison is still used xD and yeah i just typed a stupid thing

Gladiator, just because you don't know something doesn't make you stupid. I don't know how to fly an airplane, but that doesn't make me stupid, it's just that everybody knows more about certain things than others.

aww thank you for the nice comment!:) and well when someone tells me that I am wrong...I just think it is my fault and I start calling me like that...

But as far as the winner here, it's basically stabber vs slicer, T-Rex being the stabber and Giga being the slicer. They are both good at what they do in their own right when it comes to their killing technique (of course, both biting, but different ways of killing prey). 

However, when it comes down to choosing a winner for either of the two... very touchy, but I'd imagine the Giga is probably faster given it's more athletic build (judging by skeleton) and being more slender compared to the T-Rex. Given that statement, the Giga would probably be able to flank better and turn more reasonably at a higher speed, thus being able to attack on more occasions than the T-Rex would.

Furthermore, the constant slashing and cutting from the Giga's bite would slow down the T-Rex exponentially with each bite inflicted due to blood loss. However, if the Rex were to bite the Giga's leg early on, the deep puncture wound certainly cause a great deal of pain and slow the Giga down as far as being able to flank, bringing it to more the speed of the Rex.

From that point on, they should both be able to battle it out head to head and if either got a few good bites to the neck, that would spell the end for either one (the Giga, again, causing the Rex to bleed out from the neck and wouldn't take long due to the amount of blood coming from the wounds and on the Rex's hand stabbing deep into the Giga's neck and weakening it gravely).

Now for the big decision... given all of the listed info... I kinda feel like it'll go more in Giga's favor due to the info in my second paragraph, perhaps 65-35 or 60-40 in its favor.

We all learn more as time goes on, there are things you know about that i don't have a clue of, so you can't just surpass yourself as being dumb man, you are smarter on this topic than millions or perhaps billions of people are.

I completely agree with all infos you gave me, you are the first one that show credible sources (in my opinion it is a 50/50 with a little chance in more or rex because it is slightly larger but it is just my opinion).

Are you saying that I am smarter than other people on this topic? then I should be less pessimist xD and thank you!

shows*

could you tell me what do you think about my new post of t rex bigger than sue? i need an opinion of an honest person like you

S-Rex, even though Giga is faster, its relatively lighter frame makes it less durable. It's basically a fight of speed (Giga) vs strength (rex)

But I agree it's a stabber (rex) vs slasher (Giga) fight. Slashing would be a much lower way to kill than stabbing, so even if rex does bleed to death, it would still have killed its opponent

S rex, referring to the jaw strength issue with t- rex, you are correct. Strongest bite is with the rear teeth in animals. But if you think this gives gig the advantage, you need to apply the same measure to gig also. Rex has stronger bite, but can't use that strength in a fight, only a portion of that strength, then so too on the gig. Phisics aside, if gigs bite power is less than rexs, then too, gig STILL uses even less than rex. You say gig can bite and cause Tex to bleed to death, well let's look at that. Gigs teeth are much smaller than rexs, and are very slender which would break much more easily. Rexs teeth are robust, and can penatrate tissue just the same as gigs, and cause more damage. When gig bites, it does not penatrate as much, the teeth are shorter, and they only slice. Rexs teeth are longer and more powerful and when rex bites, it pulls out large chunks of flesh. Cannot compare that to each other. Gig would need to bite deeper with shorter teeth to cause serious damage, rex already has the tools to bite deeper and cause serious damage. Gig also does not have sterioscopic vision. Rex does. Rex can see where he will bite, gig is blind to the bite. Gig can't see straight ahead, he has to turn head to see where to bite then go blind to try the bite.
