Giganotosaurus vs. T. rex

I think Giganotosaurus would win, because 1. he's quite a bit bigger 2. his allosauroid design means he is generally lightly-built and therefore faster than T. rex 3. his jaws are larger and just as powerful as T. rex's and his teeth are longer as well 4. he has relatively long arms with a total of six sharp, curved claws which T. rex lacked. 5. T. rex's head level is at Giganotosaurus' arm level. Therefore, when T. rex bites, he just gets a mouthful of hook-like claws. And, before he knows it, Giganotosaurus has bit down with thousands of newtons of power and severely injured T. rex's head, which is a good few feet below Giganotosaurus'.

Wasn't Giganotosaurus more heavily built than Tyrannosaurus? Anyways, Giganotosaurus would probably win.

No, he wasn't heavily-built. There's a difference between heavy and heavily-built. Giganotosaurus was actually quite slender, making him overall lightly-built.

I agree that the Giganotosaurus was slender and fast with many teeth. I still think Giganotosaurus would still win but if Tyranosaurus Rex were to get a hold of its weak knees it would collapse to the ground. Remember TREX has 2000 lbs of crunching power on any object including anything it can sink its toothy grin on!

t rex wins

The t. rex has a lot more power in its jaws and is actually a lot stronger than the gigantosaurus. T.rex would kill it

I say if some miracle man could make this fight happen, then I'd pay big money to see it. But who would I put my money on? I don't know. I guess T-Rex. Apparently he has a bigger brain, and I doubt he'd waste any time trying to use his powerful jaws to kill Giganto quick. Heck, maybe that's an advantage with not having long arms; you don't have to think about how you're gonna make your kill. You just use your teeth. Still, Gigantosaurus does have that height advantage and could more easily get his shredding teeth on Rex. But I don't know if that could do it in one bite with that style of teeth. Sure they could rip flesh easily, especially with all that force, but one bite from Rex will crush bone. Hmm. Well, that's the beauty of betting. I say T-Rex.

I have to point out to you guys that in all reality there are WAY too many variables to say with any accuracy which of these carnivore would win in a fight. As in modern MMA or Kickboxing, the better man on papaer doesn't always win and as such in nature. Aggression, persistance, intelligence and even pure luck and situational circumstance would have more to do with the outcome of any of these supposed confrontations. It's fun to imagine things, but we're speculating about the behavior of creatures long extinct so we can only do that, speculate.

"The t. rex has a lot more power in its jaws"

Maybe, but maybe not. We don't know for certain how strong Giganotosaurus' bite was as we have not found any Giganotosaurus toothmarks. Of course, we can guess, and in fact the guesses suggest that T. rex's bite was only slightly more powerful, if at all.

I'll tell you where this estimate comes from. T. rex is known to have had a bite of 12,000 newtons. And this bite was from a FEEDING bite, so paleotologists believe that 50,000 newtons is likely for T. rex's highest bite force, about four times more powerful than it's feeding bite.

Now Allosaurus' feeding bite is confirmed to be 3,000 newtons. Since Giganotosaurus was overall larger and more powerful, we would expect Giganotosaurus to have a stronger bite force than Allosaurus, possibly 8,000 newtons. Multiply 8,000 by four, then, according to the calculation done on T. rex, you should get roughly Giganotosaurus' strongest bite: 32,000 newtons. Very close to T. rex's top bite.

Anyway, bite force doesn't have much to do with it anyway. Sharks have just as a powerful bite as a human (200 newtons), yet we all know who would win if an unnarmed human encountered a Great White.

"and is actually a lot stronger than the gigantosaurus."

Is there any evidence for this? As far as I knew, Giganotosaurus outstripped T. rex in terms of strength.

"Apparently he has a bigger brain"

For one thing, a creature with a bigger brain than another creature does not mean it is more intelligent than the other one. In fact, Neanderthals had bigger brains (and a greater brain-to-body-size ratio), yet it is clear to us all Neanderthals were not as intelligent as us humans.

That aside, intelligence doesn't always mean much in a one-on-one fight, especially when both animals are no more intelligent than birds. Think of it, the intelligent monkey vs. the fairly unintelligent lion. Who will win?

"Heck, maybe that's an advantage with not having long arms; you don't have to think about how you're gonna make your kill."

I don't think animals live by that rule. They usually use everything they've got to kill the other animal, and they never have to think how to "make your kill."

"Still, Gigantosaurus does have that height advantage and could more easily get his shredding teeth on Rex. But I don't know if that could do it in one bite with that style of teeth. Sure they could rip flesh easily, especially with all that force, but one bite from Rex will crush bone."

It also depends where. If T. rex crushes Giganotosaurus' tail bones, Giganotosaurus will hardly be weakened. If Giganotosaurus shreds T. rex's face, then I'm sure T. rex would be severely weakened.

Anyway, one last thing is that simply because T. rex is smaller, he is at a big disadvantage. Like how come they never have two wrestlers of vastly different weights competing against each other? Because it would be unfair to the smaller one.

I'll also repeat that Giganotosaurus is a lot lighter on his feet than Rex, as with all allosauroids, which also gives Giga the advantage.

yes,but I still think giganotosaurus would win

Very interesting topic. I personally think odds are 50-50 for G-saurus to beat the defending king; but definitely that would be the ultimate dino-battle ( forget about spinosaurus winning in Jurassic Park III ;))
Anyway, i think it´d be great if someone could link from here to a G-saurus vs T-rex picture or artwork, I´d appreciate it a lot...

giganotossaurs are bigger. but tyranossaurs are strongers. a litlle bit short, but stronger. i really dont know who go to win. those dinosssaurs are very powerfull. the two most powerfulls dinossaurs in the world. i really want to see this fight. came o, some one create ingen e lets see. hehehe.

What in th world are you talking about,human bites as strong as a great white shark.yOU ARE Idi_ts AND YOU are very annoingly funny,maybe some stupid shitty gogs can break your armaor a house cat can kill you.You are so weak and bizarre and i think that a small niddle coul even kill you weak motherf_ckers..uuuuuu, teeth are strong they are so big some are almost as big as my finger but they are only fuck_ng little bones do not forget that,AND I DO NOT UNDERSTAND HOW YOU CAN COMPARE SHARK WITH HUMAN OR SOME MUT YOU KNOW HOW BIG JAWS SHARK HAVE IDIO_S

Chill out man.

He was referring to the bite *energy.* not the overall damage of the bite.
In other words, if I take hold of a wooden twig and jab it forward at 100mph, into a person, it wouldn't do *much* damage.
If I use a knife, on the other hand, he'd likely be dead by now.
The Human has a small mouth, few teeth, and blunt teeth.
The shark has a large mouth, many teeth, and razor-sharp teeth.
However, the point is true, that the force of a shark's teeth biting down on you is the same as that of a human's.
Only the damage is far greater in the case of the shark's due to the potency and magnitude of his weapons -- his teeth -- which a human cannot attempt to rival.
That was a decidedly immature post, by the way. Perhaps your parents forgot to teach you manners. How old are you, 8?

The bite of the Giganoto is actually almost 1.5x stronger than that bite of a T-Rex.
It kind of makes sense considering he is overall bigger. His jaw, his teeth, his skull. Everything.

Giga would win hands down.

I think T.Rex would win, it has been recorded that it has the greatest bite force of any dinosaur. Sure Giganatosaurus was larger, but that's like saying, I know Judo and my older brother is taller than me and can kick my ass, but what about my Judo skills? So T.Rex would probably win, size doesn't matter in the old days of dinosaurs, bite force does. Only one bite would take down Rex's prey, systematically, T.Rex would aim at the right spot and just one bite, and Carolinii is down before he knows he was bit. In Jurassic Park III, Spinosaurus would have died from the first bite, but Joe Johnston wanted a change and that is why Spino won. In real life Rex would have won, sure Spino is larger but it is lightly built, now that is not an advantage, it's a BIG disadvantage, if you are slender and I come and push you, surely you would break a bone, if I push the heavy guy, he would be ok. So a massive hit would mean bye-bye for Spino. It is a fact that if Rex got a hold on to something, only an M1 Abrams can get its massive jaws out of its prey. And the bite from T.Rex at the beginning of the battle in JPIII would have sealed it, but again they wanted a change. The T.Rex that fought in JPIII was a sub-adult by the way, but even though, it brought down a prey so jaw muscles should have been developed. But then again, the T.Rex we saw was much smaller than the ones in Jurassic Park and The Lost World, a sub-adult. But I think V.Rex from King Kong would win against all of them. Seriously, Rex would win, no doubt, no matter what you watch in movies or on TV, Rex has the most powerful bite force of any animal that lived or alive, so just one bite and the fate of his rival is over.

gigntosauraus would easyley wiin its bigger, faster and in my point of veiw smarter as if it was fighting in a wide open space it would use its ground carefully the onley chance t,rex has of winning is if it is fighting in a jungle or summing

By the way, this is tyrannosauroidea, I'm just using a different (and better) nickname.

"The bite of the Giganoto is actually almost 1.5x stronger than that bite of a T-Rex.

Giga would win hands down."
Well, yes. I should have said Giganotosaurus' bite was AT LEAST a little bit weaker than T. rex's.

"I think T.Rex would win, it has been recorded that it has the greatest bite force of any dinosaur."
You need to take into consideration that we do not actually know Giganotosaurus' bite force, and, as I said before, there's a good chance he was just as powerful in terms of jaw power as T. rex.

"So T.Rex would probably win, size doesn't matter in the old days of dinosaurs,"

Size doesn't matter? I think it does. A chicken can't kill an elephant, an eagle can't kill a polar bear, or a house cat cannot kill a lion. In my opinion, the thing that matters most in a fight is size, and then, as a close second, weaponry (i.e., teeth, claws etc.)

"bite force does."

Again, it really doesn't. As Solo pointed out, you can stab a twig at somebody with a power of 1,000 newtons. The damage would be light. In fact, the person you stabbed would most likely just laugh at you, and walk off. But if you stab a knife into that person, even at just a power of 100 newtons - ten times less in terms of force - they'd be sersiously injured, most likely dead.

Giganotosaurus' teeth are actually considerably sharper and longer than T. rex's banana-shaped teeth, and with most likely an equal jaw power anyway, in my opinion Giganotosaurus wins out.

And besides, Giganotosaurus is also quicker, more agile, and has long, hook-like talons that can rip flesh and shred internal organs, something the T. rex lacks.

"Only one bite would take down Rex's prey, systematically, T.Rex would aim at the right spot and just one bite, and Carolinii is down before he knows he was bit."

I don't believe this is correct. As proved by Erickson (the guy who did the T. rex bite force calculation in the first place), a tooth with 12,000 newtons of energy behind it would gouge out a 4-inch hole in a bone. Which is good, of course, but considering many dinosaurs have been found with gaping holes through their entire skulls and many broken bones, and they survived their injuries, then I doubt a single T. rex bite even to Giganotosaurus' head would immediately kill it. That's just extreme.

"It is a fact that if Rex got a hold on to something, only an M1 Abrams can get its massive jaws out of its prey."
That is complete speculation, not a fact. In fact, I believe it would take a lot less than an M1 Abrams tank to kill a T. rex. A grenade-launcher, a rocket-launcher or even a well-placed shot with an elephant gun should be able to take T. rex down.

And, by the way Jony, that was one of the most immature posts I have ever seen. Don't jump to conclusions and then hurl a thousand insults due to your mistake. THAT is truly "annoyingly funny."

Gigantosaurus weighed 8 tons,T-rex only weighed 7. Gigantosaurus was bigger. He was also stronger and faster than T-rex.T-rex would die.

Gigantosaurus is bigger but i think t>ex will win
