Would Spinosaurus win a fight with T-Rex? I think yes.

1. It can uses its fornt claws.

2. Its a littil biger.

3. Just look at it!

Spinosaurus achieved widespread fame as the main antagonist in Jurassic Park III. It is portrayed as larger, more powerful, and more vicious than Tyrannosaurus, epitomized by a scene in which the two resurrected predators battle and Spinosaurus emerges victorious by twisting its opponent's neck.

No such battle could ever have taken place in real life, since Spinosaurus and Tyrannosaurus lived thousands of miles and tens of millions of years apart.

Aside from the implausibility of the battle itself, it seems unlikely that Spinosaurus could have simply shrugged off a neck bite by Tyrannosaurus, which possessed among the strongest jaws ever known in the animal kingdom.

Spinosaurus did share its habitat with two other theropods that equalled or exceeded T. rex in size: the massive carnosaur Carcharodontosaurus and the large but relatively lightweight abelisaur Deltadromeus.

Although the three gigantic predators probably occupied different ecological niches, they may have occasionally come into conflict over prey or territory.

Spinosaurus

I know all that Im just saying who would win?

well i think t-rex would win. spinosaurus may have the size but t-rex has got the power. t-rex was very heavily built and had very power full jaws. it would be like a rottweiler vs a great dane. the great dane is bigger but the rottweiler is stronger and has very power full jaws like t-rex did. so yah my moneys on t-rex

Spinosaurus was a fish-eater, with long, reletively weak jaws. Tyrannosaurus was smaller and lighter, but much stockier and more muscular, with short, powerful jaws. In fact, pound for pound, tyrannosaurus was a much stronger opponent, with one of the most powerful bites in all of history.

Given that best estimates for dinosaur speed place the two creatures in roughly the same range, I would think that tyrannosaurus would have the advantage. A more intelligent fighter (ie, a human) might be able to take advantage of spinosaurus's greater reach, but in all likelihood, the animals would not be clever enough to do so.

Of course, so little is known about dinosaur behavior that it is next to impossible to judge the outcome, even if the two fighters had ever existed side-by-side in the same environment. However, if bets were being taken, I would probably put my money on the tyrannosaur.

T rex cause i love trex.

and Jurassic park got alot of things wrong

speaking of which JP4 is on the way im sure they might do the whole kong thing and have a spino and Trex battle ill pay to see that

really? JP4 is coming out? do you have a link on some info? all i have herd is a bunch off rumors. i would love to see it.

Yes I've been following it sines the last one came out. Heres a link.

It said that alot of thing in this one will fix the dinosaurs. Like the V-raptor will be the right size( 2-3 feet tall 6-7 feet long). And it will have fathers.

I think we are forgeting the fack that Spinosaurus cood use it fornt claws. I cood grabed the T-rex or cut it.

If spinosaurus grabbed tyrannosaurus, it would have to put itself in a position where tyrannosaurus could employ its match-winning bite. Scratching would not inflict much harm unless a lucky blow was scored against the eyes; even then, tyrannosaur's head structure would ensure that the eyes themselves would probably escape serious damage. The best spinosaurus could hope for is to drive the tyrannosaur off. A kill is probably out of the question against a predator as powerful as that.

-Pilgrim

All spinosaurus would have to do is push T-rex over. Resuach tells us if it falls on it chast( ribes) its ribes would have borkin and it would have die form damge to to it heart and lougns.

Spinosaurus would win hands-down. Unfourtunatly, the died out about 90 m.y.a., nearly 20 milion years befor the first Tyranosaurus. Eh, T. Rex will always be my personal favorite.

Same goes for ANY large theropod...The fact is, it would be hard to push 9 tones of Tyrannosaurus down...

T-rex would win by its jaws. Think of Tyrannosaurus like a crocodile...What it grabs hold of you, its not letting go.

that may be true but like we said t-rex was very strong and heavily built guys like that don't go down easy.

yeah but spinosauras has the jaws of a crocodile.

Such research is very much in dispute. Personally - and I base this on nothing more than my own (admittedly limited) understanding of biology - the idea that a creature could evolve which would die or become critically injured if it tripped seems more than a little far-fetched.

In addition, spinosaurus did not have much of a mass advantage over tyrannosaurus. It was far larger in tems of height and length, but much more slightly built. Rushing the creature would ensure a protracted grapple, which again puts tyrannosaurus in a position to employ its bite. This is not a strategy I would employ if I were a spinosaurus. In fact, it's exactly what I would do if I were the tyrannosaur, because in close combat, the advantage is mine.

The only hope for the leaner spinosaurus, in my opinion, is a series of darting hit-and-run attacks. It has far greater reach and can afford to nip and snap at the exposed bits. An enraged tyrannosaur could attempt a charge, at which point a quick-witted spinosaurus could swing in and grab hold of the neck. Once it is behind tyrannosaurus, those powerful jaws are rendered useless.

The problem, of course, is that this involves baiting the tyrannosaur into a charge and darting past. This largely depends on the spinosaurus being more clever and probably faster, as well. It must avoid the tyrannosaur's charge. Tyrannosaurus is smaller and stockier, and in this case, that could be an advantage. It can pivot more readily and turn to intercept, which would leave spinosaurus's flank undefended.

Of course, I'm just toying with the concept. In actuality neither predator would be intelligent enough to develop anything resembling a coherent strategy (they were very bright for dinosaurs, but still rather dim compared to modern animals). Furthermore, neither would be interested in a fight to the death, so most likely the match would end with one or the other being driven off.

-Pilgrim

In a conflict between a Spinosaurus and a Charcharodontosaurus, it would be more likely that a dinosaur would be scared off...Not attacked.

I might be wrong but the Spinosaurus is in fact smaller than a t-rex but made bigger for the movies. Same with the velociraptor, it is only 1 meter tall not the large man sized thing in JP 1, 2 and 3.

I could be wrong but I read it out of this magazine I use to buy years and years ago called "Dinosaurs!"

Actually. Spinosaurus is larger than T-rex...We cannot say for sure, but it was probably longer by 5-10 feet.

Tyrannosaurus is generally estimated to have been in the area of 40 feet long, give or take. Spinosaurus estimates vary wildly, due to the fragmentary nature of the specimens (many of which were destroyed in World War II and thus are not availible for comparison), but it is widely believed to have been roughly 50 feet long on average and may have been upwards of 60 feet.

There was a debate regarding the size of spinosaurus and its possible claim to the title of largest theropod dinosaur in the past few months, which you can read here.

As for the Jurassic Park films, they are indeed inaccurate, but I have discussed this at length in various other threads, so I will humbly leave the matter at that.

You all seme to be forgeting that spino was just as poweful. And if it was nock over it cood stop it self with its longer then T-rex's arms. And it cood pick it self up faster.

I just thart of some thing, Spinosaurus ate fish wich mines it "mite of" Been able to swim. what if it attack the T-rex as it was geting a drink of water. Like a croc.

First off that Velociraptor was more likly a Deinonychus. They most likly chaned the names arond. A Velociraptor is ONLY found in asian. Not in the US.

And I look up the two dinosaurs (T-rex and Spinosaurus). I fund it on the www.jpinstitute.com. It tells the truth about the dinos. Not what was in the movies. I look it all up in books so thats how I know thae tell the truth.

Tyrannosaurus rex


Pronounced:tie - Ran - o - Saw - rus
Diet:Carnivore (Meat-Eater)
Name Means:"tyrant lizard"
Length:40 feet (13 m)
Height:16 feet (5 m)
Weight:6 tons (6,000 kilos)
Time:Late Cretaceous - 67 MYA

Spinosaurus
Spinosaurus aegyptiacus


Pronounced:Spy - no - Saw - rus
Diet:Carnivore (Meat-Eater)
Name Means:"spine lizard"
Length:45 feet (15 m)
Height:16 feet (5 m)
Weight:6 tons (6,000 kilos)
Time:Middle Cretaceous - 100 MYA

While the size and body shape are closer to deinonychus, they were indeed intended to be velociraptors. This is taken from the novel, which featured (correctly sized) velociraptors.

As to the question of spinosaurus's arms, I don't think they really enter into the picture much. Though they were longer than tyrannosaurus's they were not long enough to make much of a difference. Spinosaurus still couldn't scratch its chin.

As to the question of a battle at the water's edge...an interesting proposition, and more to spinosaurus's advantage. However, the problem is that crocodiles, even very large crocodiles, are only a couple of feet high. Spinosaurus was, as you pointed out, over 15 feet tall, with a prominent sail. It simply could not hide in shallow or even moderately shallow water. Thus, it could not snatch its opponent by surprise - it would still have to grapple, which again is not to its advantage.

-Pilgrim

Well know one ever sead T-rex had brains.

Okay, I had a good belly laugh over that one.

-Pilgrim

I can imagine the Spino flailing away at the T-Rex like a girl... and the T-Rex EATING the arms, then the Spino....

I hope you were sarcastic...

Spino has no adaptations for swimming whatsoever, and could not ambush prey from water just a couple feet deep.


2 spino arms can stop 6 tons from falling? I don't think so....

both dinosaurs would just get right back up if they fell....

T Rex had (though short) some of the (pound for pound)
stougest arms out of any of the dinosaurs.
Tyranosaurus would beat him hands down

All they were used for was balance and possibly to help get up...

Ah, but there is a Utahraptor, which is about the same size as in the movie. They were large, mean little buggers. And, as I was told by my paleo prof a few years ago, Spielberg had artificially increased the size of the raptors in the movie to make them more menacing. The scientific community snickered at how ridiculously sized they were. A year or so later, they discovered a type of velociraptor that was the same size.

Spinosaurus vs T-rex? I dunno. Spinosaurus has the arms and size advantage, but his jaws were much weaker since he was a fish-eater (as someone pointed out) and have you ever seen a Spinosaurus aegypticus tooth? It's small and weak. Not quite as fearsome as JP3. T-rex has teeth built for crushing bone, while Spinosaurus has teeth built for catching fish, with delicate bones. It would be hard to tell which would be the victor. In water, I'd say Spinosaurus, since he has an advantage there.

Now if one of them had lasers, then it wouldn't be contest. But I think lasers on dinosaurs would be cool.

Small and conical for holding slippery fish


and dangerous

Frogfish i never said he used them for fighting all i said
was ol' T-Rex had some musscular arms. i mean heck
could u imagin trying to stand up without using your arms
if u weighed 5-7 tons

I was just backing you up...

ok frog fish just making sure no ones making
funny me inteelicktulaness lol
but seriously trex would win

Utharaptor is not a type of velociraptor. Both are dromaeosaurs ("raptors"), but they are different species. The fundamentals of the story are true - the largest known dromaeosaur prior to Utahraptor was Deinonychus, at roughly 5 feet tall - but velociraptor most definately could not attain anything near the size shown in the film. At least, no known species of velociraptor could. Utahraptor was roughly the correct size but, as I mentioned, was an entirely different species.



I don't think our government is spending anywhere near enough money towards equipping dinosaurs with laser beams. We cannot afford a dinosaur laser gap!

-Pilgrim

Could u imagin that
instead of riding a horse to battle u could ride a
utahraptor equipt to the teeth with lasers and
missle launchers

yea, if you could keep from getting eaten!

put a muzzle on the little puppy

I don't want the job of putting the muzzle on...

umm get stupid people
to do it

LOL... you might have a plan

LMAO you guys crack me up

personaly i feel that spinosaurus was more keen to hunt then ttyranosaurs i feel it was more like a hyean strong buiild very powerful jaws but would mostly just chase other animls away from there kills by throwing its bulk around. not that it cant hunt i feel it was perfectly able to like the hyeana but would rather just steal other kills. now i feel that the spinosaurus was more liek a lion who would usualy hunt but would also scare other animls away to scavange off there kills to so basily what im saying is they oth would be able to hunt and scavange but spino sarus would hunt more and tyranosauruswould scavange more. now with that said hyeanas and lions hate eachother. and a lone lion and a lone hyeana a lion would win a fight. now when u put the hyeana with its running buddies which hyeanas uses there numbers of 40+ to swarm then a lion would ususaly loose or even a pride unless the males show up haha then its a whole other story male lions are some times called hyeana kilelrs by locals. i saw one video a male had a hyeanas head in its mouth turned around and drove a paw into another ones head and slamed it into the gorund and killed it that was intense. but any way off topic most of the time when two top preadators come face to face its ususaly a stand off the threat displays until one baks down no point in fighting and loosing cause i thne die of fighting and winning but getting hurt and thne u still die becuase u cant hunt. but if neither back down then its a fight. now down to the fight just because t-rex pound for pound coudl be stronger means nouthing a jaguar is pound for pound stronger thne a tiger but a tiger would iminate it due to its size and its still stronger thne the jaguar. so a hink spinosaurus would use its size to its advantage. it would most likely grab on to a fleshy are liek the neck or thigh due to its better reach and thrash its jaws like a crocodile would. then rip off a large section of flesh mortaly wounding the animal. a t-rex's jaws are shorter so it doesnt have the added reac of its counterpart neither of there arms would make to much of a diffrence the only thing might by spinosaurus arms might be if anythinga distraction for t rex even if they dont hurt no one likes getting poked in the ned i tihnk both howwever would back off after snaping at eachother a few times and realising neither can win without taking mortal wounds anyway. it would be like a lion and tiger fighting a tiger might win but a lion would certnly get in some good shots

T-rex probably hunted more though...It had an enlarged olfacatory and optic chaisms. Its also had teeth designed for cutting meat, not crushing bone

used to detect rotting flesh and spot dead animals across large areas of land/ view any flying reptiles circuling over an area (similar to vultures of today) as for the teeth no one said he ate bones it is possibl that he only ate flesh off the animal. its logical that it may have just trecked all over the place of used its keen eyes to watch the other preadators hunt down the animals and then scare them off and eat the flesh off that animals and move on. although most not all scavangers eat bones

This does not prove that t-rex was weaker.
Rex still has the strongest jaws in the fossil record,
and spino is like a lightweight compared to Rex's
bulk

umm kid idk if u read anything but spinosaurus has been recentaly classififed as the largest carno dino its bulk was at least the same as t-rexes

But it is MUCH MORE LOGICAL that he used his enlarged optic chaism for hunting...


I doubt it...scavengers of today need to be able to crack and eat bone as thats normally what is left.

Not so fast...Saurophaganax is the largest land predator of all time...A giant allosaur of N. America that possibly reach lengths of 60 feet.

It is reasonable to say T-rex was stronger as it was a full-fledged carnivore, while Spino was mainly a fish-eater.

this remind me of some sick video of a bear fighting a lion. Both equal sized.

The bear can take beating, the lion, gets tired easily. Match ended when the lion starts panting and stayed away from the bear, and the bear stopped harrasing the lion. (yup, the cuddly bear was harrasing the lion)

possibly, spino vs t-rex would end up more or less the same.
