    First off, no, this is not speculation for what's going to go down in the movie. This is what you think would go down if they were to encounter in a "natural" situation. I'll get into some specs.

    T-Rex
    Click for Options
    Weight: 7-9 tons
    Length: 11-14 metres
    Height: 3-5 metres (don't quote me on that)
    Speed: 32 KM/H
    Bite force: 3-15 tons PSI (so I've heard), average 7-9 tons PSI
    Vision: Binocular
    Smell: Second best in fossil record
    Arms: Short, end in two fingered hands
    Body: Heavily muscled


    I-Rex
    Click for Options
    Basing information off trailer and website, as well as assumptions based off DNA in her (Rugops, Majungasaurus, Carnotaurus, Giganotosaurus).

    First off, she was designed to be bigger than T-Rex according to Wu I believe.

    First off, "bigger" is a vague term. It could mean taller, it could mean longer it could mean heavier, it could mean any combination of the three. Hear me out on this, looking at its build, it isn't as muscled as T-Rex. At length parity, I believe T-Rex was heavier. This is speculation

    Weight: 8-10 tons full grown
    Length: Currently 12 metres according to site, likely 13-14 metres full grown
    Height: Probably 3-4 metres, likely 5 metres full grown
    Speed: 50 KM/H
    Bite force: 3-5 tons PSI
    Vision: Similar to Tarbosaurus, slightly binocular
    Smell: Most likely pretty good, but not T-Rex good
    Arms: Large with elongated middle finger
    Body: Fairly Allosaurian, built more for agility, not brute strength. Skull similar to Abelisaur


    I-Rex

    Advantages:

    Heavier
    Possibly more agile
    Larger arms
    Possible camouflage ability

    Disadvantages:

    Likely not as tough
    Lack of depth perception can be hinderance
    Higher cent of gravity

    T-Rex

    Advantages:

    Higher bite force
    Likely tougher
    Better vision
    Likely just as strong
    Lower centre of gravity


    Disadvantages:

    Possibly lighter
    Less agile
    Small arms
    No camouflage, though smell could cancel out camo



    Let's try to be calm. If you disagree, don't hesitate to post what you disagree with. I'm sure everyone has their own theories on I-Rex, so don't give me crap because my theory doesn't line up with yours.


    I'd say this fight to be 50-50, maybe 45-55 either way.

    Why would I rex have weaker senses then rex? There is no evidence for it. And why wouldn't oit be tough?

    vut great post.

    Lord Vader

    Never said weaker senses. I said that I-Rex's sense of smell likely wasn't as good a T-Rex's. T-Rex had the second best sense of smell on the fossil record. Saying I-Rex had a poor sense of smell because it's sense of smell isn't as good as Rex's is like saying TLW was a crappy movie because it wasn't as good as JP. It's good, just not as good.

    The eyesight, again, never said it was poor. I said its vision was likely similar to that of Tarbosaurus.

    Toughness, well, that's up for debate. I just assume it's not as tough because it's not as heavily built. If you're fast and/or agile, you sacrifice something. If you're big and strong, you sacrifice something. I have a buddy who's freakishly fast. He's slim, but holy crap can he ever run. He can't take a hit worth sh!t though. On the other hand, I'm rather stocky. I'm big and strong, but I can't run that fast and I'm not very agile (I can do a cartwheel though). If someone hits me, I brush it off and hit back. Basically, the more lightly built you are, the less of a hit you can take. Not saying I-Rex can't take a hit.

    Wow. So many words. I just got out of school.

     

    didn't mean to say crappy ssenses. I meant to say scent. And we may have no evidence of other animals so let's not make ass about that.

    and nice analogy. I would be in between you and your friend.

    As it stands, T-Rex has the second best sense of smell in the fossil record. As I say this on Friday, Febuary 13, 2015, that is a fact. That will remain a fact, until something comes along to disprove that. Until then though, I can say with a fair degree of confidence that T-Rex has the second best sense of smell of all time.

     

    My bad. Typos happen.

    In my view bigger is a term describing I. rex's overall size compared to T. rex meaning longer and taller. One thing you overlooked that, in my opinion is a huge factor is the intelligence of I. rex. It has come out from several sources that I. rex is a very intelligent animal, one that 'kills for sport'. Killing for sport suggests a vicious streak to go with the intelligence. To me this illustrates a creature capable of tactical decision making which goes very nicely with its supposed camouflage ability. The sense of smell for T. rex could potentially negate this ability however; in a chaotic environment where there are so many different smells to process T. rex could be surprised.

     

    In my view an animal as intelligent as the I. rex is purported to be it would exercise patience in trying to tackle an adversary as large and powerful as T. rex. It would ensure that the odds are in its favor and this, coupled with speed, agility and the knowlege of what it wants to do before the fight even begins would make I.rex an extremely dangerous opponent. I'm sure that I will ruffle a few feathers in saying this but I am going to cast my lot with I. rex in this contest.

    I am going to say I-Rex wins...although I love Rex and Spino,to me, not even in the JP universe, JP3 Spino or Rexy could actaully beat her...

     

    It is a movie made animal which = Winner.

     

     

    A hybrid, designed to be better. 

    Just to powerful...BIGGER. LOUDER. MORE TEETH

    Looks to have a strong hide, perhaps bullet proof. Crocodile like.

    Huge arms may allow to pick up things, or grab. Cough! Jp3 spino! Cough!

    Maybe able to unhinge its jaw, look at how wide that is....

    Maybe able to go on or 4s may be able to swim.

    I reckon its eye sight will match that, if not beat T-Rex. 

     

    It is also highly intellegnet. She tricked those workers in the cage and made them think she climbed out of a 40 feet high wall!

     

    May have human DNA (rumored) so it has that thumb, hunts for sport, and is smart.

     

    Now I reckon the camouflouge is OP. But Rex, may be able to smell her, (I-Rex seems to have a weaker sense of smell, couldn't really detect Owen under that vehicle.)

     

     

    And last but not least, this is just me, but I reckon, since it is a movie, it could be like the V-Rex from King King, they were juveniles and were huge, this to me just fills like a monster thats get bigger, a younger killer "learning where she fits on the food chain". And I reckon she is heavier, stronger, longer, taller, smarter, faster, more powerful....not even fully grown...

     

     

    Now these are just speculation, forgive me, my Australia website hasn't updated with the I-Rex yet, and I did this quickly.

     

    Nothing against Rex.

     

    And guys remember it depends. On what? What kind of dinosaur they cooked up in that lab.

    I wouldn't make a descision just yet... For now, I'm going with a tie. One wins the battle while the other succumbs to its wounds after.

    Spinofan, size refers to weight. not length and height.

    also, addressing other parts of your post:

    - intelligience is not a factor in fights, animals fight via instinct.

    very intelligent animal, one that 'kills for sport'. Killing for sport suggests a vicious streak to go with the intelligence

    -so do humans and chimps, but they get wrecked by just about every large carnivore they're sympatric with. 

    Now, i await your response. Feathers were not ruffled by your response (why even state this?) but, i felt like addressing the innacuracies in your post so yeah.

    I now I said I-Rex would probably win, but I don't want to jump to any conclusions...

    In my previous comment, I stated that the Indominus will win 99% of the time. I still stand by this decision, and here's why:


    Offense: When it comes to offense, both animals have impressive weaponry. The T. rex has its amazing bite force, but that's really about it. The Indominus likely has an impreesive bite as well, though we'll say it's lower than the T. rex's. However, the Indominus likely has a venemous bite, which will make it so that this animal only needs one good bite to kill the T. rex. On top of this, it also has vastly superior arms.
    Winner: Indominus rex.


    Defense: Both animals have tough hides, however it appears as if the Indominus' hide may be thick enough to stop bullets. This is a clear advantage for it.
    Winner: Indominus rex.


    Intelligence: Carno, what you said about animals primarily fighting with instinct, is only partly right. Although many animals certainly do rely on primarily instinct while fighting, when an animal as smart as the Indominus, which is capable of making and carying out plans fights, it's intelligence does become a huge factor.
    Winner: Indominus rex.


    Size: Well, the T. rex is heavier, but the Indominus is taller and longer. Personally, I feel that weight is more useful in a fight, as it can be used to push around the other, animal.
    Winner: Tyrannosaurus rex


    Speed: The Indominus is confirmed to be faster. 'nuff said.
    Winner: Indominus rex.


    Other: So, It is confirmed that the Indominus can turn invisible, and can likely detect heat signatures as well. The T. rex on the other hand, has amazing senses in general. It has been argued that these would negate the Indominus' invisibility, and I agree under certain circumstances. If the Indominus is downwind of the rex, the rex will certainly smell it. If it is upwind, the rex will not. I for one, am positive that the Indominus is smart enough to figure this out, and take advantage of it. The T. rex may still find it, but it will have a hard time.
    Winner: Indominus rex, but barely.

    So, now you have an idea of why I think the Indominus will win 99% of the time. I think a good analogy for this fight is that you have a Navy SEAL (The Indominus) fighting a security guard with a shotgun (Tyrannosaurus). In this fight, the Security Guard might get lucky, but the SEAL will beat him almost every time.

    In the movie though, the T. rex will totally win.

    The only reason t.rex will win is because of movie logic.

    To be fair, speed is irrelevant in a fight. Big deal that your and run 50 K an hour, your opponent is ten feet away. In a fight, it's short bursts of speed that help. I'd say I-Rex does have better acceleration to be fair. 

     

    Regarding Spino fan's comment. 

    Sure, it may be smart, but THAT smart? If it was, youd think it'd realize it has a pretty sweet deal in the paddock. It eats on a set schedule, it's safe, and all it has to do is be there. 

     

    I'm sure there are details that people have posted that I failed to address and I'm sorry for that. Gold fish memory.

    Well scent and sight aren't as important since your opponent is ten feet away.

    Lord Vader

    Feb-14-2015 5:00 AM

    Depth perception helps at all distances and scent is only relevant if I-Rex goes into camo mode, which it may not even be able to do. 

     

    JPC, the bullet proof hide comment. Nothing is bullet proof if you have a big enough gun. Just because a 12 gauge shotgun may not be able to do anything to I-Rex doesn't mean it's immune to 12.7x99 or 20mm Vulcan. That machine gun in the chopper was probably a .50 cal, but the guy was missing. The guy is shooting at a moving target, from a moving helicopter, in full auto. Everything is moving, and the recoil is harmful to accuracy.

    The awful thing would win. I-rex is basically a much better predator than T.rex. T.rex would get destroyed in a few seconds.

    Intelligence IS a factor in fights because the more intelligent animal is going to usually set the terms of engagement. Think of a Jaguar hunting a crocodile. The Jag knows it is overmatched in the water so it waits until the croc is on land where it has the advantage.

     

    When people say 'bigger' they do often refer to weight but this is not always the case. I have seen many instances of it referring to length and height and while I agree that it is somewhat inaccurate it still gets the point across.

     

    Yes, humans and chimps would more than likely be wrecked by any large carnivore, but as I am suggesting with I. rex humans use their intelligence to set the terms of engagement (ie; guns, traps, etc) and chimps are smart enough to stay out of harm's way. 

     

    I am not suggesting that I. rex is going to bomb T. rex or anything but I do believe that it is smart enough to set the terms of engagement when it has the advantage.

    Lord Vader

    Feb-14-2015 11:10 AM

    Perhaps. Sure, it's most likely highly intelligent, but not a bloody genious. It'll try to ambush, and it may be able to pick up on an opponent's weak spot, but that's about it. There's no terrain that'll give it an advantage over T-Rex. The only pre-combat advantage she'll be getting is being up wind of T-Rex, but I'm pretty sure most predators can figure that out.

    That's called specialized hunting, spinofan. Put a cheetah in that situation, it won't do such. Also, jaguars don't hunt crocodiles, they hunt the much smaller yacare caiman.

    When people say 'bigger' they do often refer to weight but this is not always the case. I have seen many instances of it referring to length and height and while I agree that it is somewhat inaccurate it still gets the point across.

     It's still not the proper use of the term -- sie, again, refers to weight. not length and height.

    I tell people the intelligence thing but they don't listen.

    and I think I-rex is heavier so it is bigger.

    Lord Vader

    Feb-14-2015 11:55 AM

    TK, you think I-Rex is heavier, therefore you think it is bigger. Not you think its heavier, therefore it's bigger. That's what you meant. I also think I-Rex maxed out at larger than Rex.
