Large therapod dinosaurs strength?

1. Rex 2 Giga 3 carchar 4 spino 

reasons for each. 

Rex: most heavily muscled of the four, and the heaviest.

Giga: Second most heavily muscled of the four, as well as second heaviest 

Carchar: thrid most heavily muscled, thrid heaviest.

Spino: fourth most heavily muscled, and based on Nat Geos estimates the lightest.

I've always winders that and I was actually about to make a thread in on Dino strength tomorrow btw I agree with your list

Here's my opinion on the strength of The Big Four.

1- Tyrannosaurus Rex

T-Rex was the most heavily built. Tyrannosaurs in General were heavily built, and Tyrannosaurus was no exception. It hunted Hadrosaurs. Hadrosaurs, like sauropods, would likely use their tails in self defence. However, unlike sauropods, their tails were no whip-like. Where Giganotosaurus would be avoiding the tail altogether, Tyrannosaurus needed to be able to take a hit better than any other members of "The Big Four."

2/3- Giganotosaurus/Carcharodontosaurus

Giganotosaurus and Carcharodontosaurus are actually interchangeable if you ask me. Both were sauropod slayers, both lived in areas infested with predators, and both were Carcharodontosaurus. Charcarodontosaurs, like Allosaurs, were not heavyweights like Tyrannosaurs. They didn't need to be. Where Tyrannosaurus would be hunting Hadrosaurs and only having the tails to avoid, Giganotosaurus and Carcharodontosaurus had something much worse to worry about: Being crushed. They didn't need to be heavyweights to take on sauropods. They needed to be agile to avoid being crushed, as well as the whip-like tails.

4- Spinosaurus

Spinosaurus was mainly piscivorous. Unless you've been living under a rock or only know it from Jurassic Park 3 and Monsters Resurrected, this isn't news. Spinosaurs in General were lightweight animals. They weren't pushovers by any means, but they were delicate for their size. Spinosaurus needed the strength to catch fish and haul them to land while their still struggling. It would take some strength to haul a struggling fish that weighs a ton, but not much.

Until we actually have them in front of us, no one can say for sure.

The reason I belive, giga was stronger carchar is....

Carchar, actualy has a more slender, bulid then giga, and was most likely lighter...

Here's my opinion:

1. Spinosaurus

2. Charcarodontosarus

3. Giganotosaurus

4. T-Rex

Now, heres my reasoning to why i put these in their place:

1. Spinosaurus, i think, was definately the strongest due to its immense size, competition, and like i've always stated, a 12-15 ton monster does not simply feed on mainly fish, as it would need the energy to wait and finally attack its slippery meal it doesnt always get to call its own (much like a fish getting off of our hooks today). Something that big needs to have energy constantly restored into its body, so it needs something BIG to constantly replenish its appetite each time it needs the energy to have it for its next ambush, for defending itself against other large predators, or simply just walking around to find other neccesities.

2. Charcarodontosaurus i put at two simply because of its weight mainly (7-9 tons). This is because a body that is 40-46 ft long divided into 7-9 tons doesnt seem like it would be too heavily muscled. Yes, it was definately powerful, it preyed on sauropods a whole lot and needed the strength to do so, but it didn't have as much muscle in itself as my number one pick due to one sauropod being enough to feed it for a week, where as Spinosaurus used its energy up so quickly it needed to feed almost all of the time, which the exercise to find its prey and take it down kept it strong and muscular.

3. Giganotosaurus is my #3 because of the less competition of the last two. Yes, there was some, but none of its competetors were close to its size, which it used to scare away the smaller predators from their kill. This leads me to ultimately get to my point of it not having to really hunt or defend itself from other predators as much as the previous two, as it could just scare away other competition, but not as much as my #4 pick's strength...

4. Tyrannosaurus, yes, i know a lot of you would like to argue with me about this, but Tyrannosaurus had little to no competition whatsoever. A lot of the time, it would find a fresh kill made by much smaller predators with its keen sense of smell and steal it from them, due to it being much larger than the ones who actually killed it. Its much like MRE's for T-Rex, as it can find and scavenge already dead animals with little effort as to getting it, as no other predators would even think twice about defending their own kill against T-Rex, even if it starved them. Now im not saying T-Rex was a pure scavenger, but it only really went out and killed its own food when it couldnt find carcasses laying around. With this being said, it probably had a higher weight than the last two, but that is due to fat, not muscle, because it didnt get the exercise all of the above did because it didnt have to look far for its next meal, nor fight for it, which it is pure logic that if you dont have to walk nor do it because you dont have the common sense to do it due to getting exercise (which no dinosaur had because it has to do with your environment and competition, which keeps you moving depending on the environment, competition, size, and overall, fight to survive!)

1. T.rex(by a longshot)

2. Giga

3. Carchar

4. Spino(though it and Carchar are close)

s- rex, trex had other trex's or worry about, we have various fossils showing rex biting each other and such. And spino at the top? It was the lightes compared to size, at somewhere between 6 tons to 9 tons. And those fish did provide large amounts of nutrition, and the fish were plentyfull.

S-rex, spinos weight is now 6 tons...

I will say, fish are very high in nutritional value

Are you trying to disprove me or what, because it isnt going to work due to me doing large amounts of research of the regualar bases, especially now that im in paleobiology and paleontology. Yes, of course, T-Rex had other T-Rex's to worry about, as well as the other dinos listed, but they other have more than just themselves to worry about, as i have already stated. And its not about nutrition here, its about Spinosaurus probably not having the patience just to sit there and wait for a fish that definately isn't sure to be his, so it did what any other predator would do and go for the easier kill with less patience at risk.

We're just making some points, something you do quite a bit. Don't get so defensive.

Well ive seen you guys do the same, and on top of that im sick today and not in the best of moods.

Well, don't let that cloud your judgement.

Also, I'd like to point out that when it comes to strength, it varies greatly depending on what part of the body you're examining. So, now for my lists.

List 1: Bite Strength.

1. T. rex. (no real surprise there)

2. Carcharodontosaurus.

3. Spinosaurus.

4. Giganotosaurus. (Placed in last due to it most likely bleeding its prey to death)

List 2: Arm Strength

1. Spinosaurus. (This predator likely relied on its arms more than the others)

2. Giganotosaurus (Would've helped with bleeding out its prey)

3. Carcharodontosaurus

4. T. rex (don't even pull the fact that it could lift 450 lbs, that's irrellevant compared to the others arms.)

List 3: Bone/Skeletal Strength

1. T. rex. (The sturdiest carnivorous dinosaur ever. No question.)

2. Giganotosaurus. (Essentially a beefier Carcharodontosaurus)

3. Carcharodontosaurus.

4. Spinosaurus. (That sail is a liability, and if its legs are as scrappy as sereno's model shows them to be...)

I try not to, but that there is the majority of the human population for ya, most are not in the best of moods when they are sick.
