Tyrannosaurus rex
Tyrannosaurus is a genus of coelurosaurian theropod dinosaur. The species Tyrannosaurus rex (rex meaning "king" in Latin), commonly abbreviated to T. rex, is a fixture in popular culture. It lived throughout what is now western North America, with a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the upper Cretaceous Period, 67 to 65.5 million years ago.[1] It was among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event. Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to the large and powerful hindlimbs, Tyrannosaurus forelimbs were small, though unusually powerful for their size, and bore two clawed digits. Although other theropods rivaled or exceeded Tyrannosaurus rex in size, it was the largest known tyrannosaurid and one of the largest known land predators. By far the largest carnivore in its environment, Tyrannosaurus rex may have been an apex predator, preying upon hadrosaurs and ceratopsians, although some experts have suggested it was primarily a scavenger. The debate over Tyrannosaurus as apex predator or scavenger is among the longest running in paleontology. Tyrannosaurus rex was one of the largest land carnivores of all time; the largest complete specimen, FMNH PR2081 ("Sue"), measured 12.8 metres (42 ft) long, and was 4.0 metres (13.1 ft) tall at the hips. Mass estimates have varied widely over the years, from more than 7.2 metric tons (7.9 short tons), to less than 4.5 metric tons (5.0 short tons), with most modern estimates ranging between 5.4 and 6.8 metric tons (6.0 and 7.5 short tons). Packard et al. (2009) tested dinosaur mass estimation procedures on elephants and concluded that dinosaur estimations are flawed and produce over-estimations; thus, the weight of Tyrannosaurus could be much less than usually estimated. Other estimations have concluded that the largest known Tyrannosaurus specimens had a weight exceeding 9 tonnes.

Spinosaurus aegyptiacus
Spinosaurus is a genus of theropod dinosaur which lived in what is now North Africa, from the lower Albian to lower Cenomanian stages of the Cretaceous period, about 112 to 97 million years ago. Spinosaurus may be the largest of all known carnivorous dinosaurs, even larger than Tyrannosaurus and Giganotosaurus. Estimates published in 2005 and 2007 suggest that it was 12.6 to 18 metres (41 to 59 ft) in length and 7 to 20.9 tonnes (7.7 to 23.0 short tons) in weight. The skull of Spinosaurus was long and narrow like that of a modern crocodilian. Spinosaurus is thought to have eaten fish; evidence suggests that it lived both on land and in water like a modern crocodilian. The distinctive spines of Spinosaurus, which were long extensions of the vertebrae, grew to at least 1.65 meters (5.4 ft) long and were likely to have had skin connecting them, forming a sail-like structure, although some authors have suggested that the spines were covered in fat and formed a hump. Multiple functions have been put forward for this structure, including thermoregulation and display. Dal Sasso et al. (2005) assumed that Spinosaurus and Suchomimus had the same body proportions in relation to their skull lengths, and thereby calculated that Spinosaurus was 16 to 18 meters (52 to 59 ft) in length and 7 to 9 tonnes (7.7 to 9.9 short tons) in weight. The Dal Sasso et al. estimates were criticized because the skull length estimate was uncertain, and (assuming that body mass increases as the cube of body length) scaling Suchomimus which was 11 meters (36 ft) long and 3.8 tonnes (4.2 short tons) in mass to the range of estimated lengths of Spinosaurus would produce an estimated body mass of 11.7 to 16.7 tonnes (12.9 to 18.4 short tons).

I'm not biased against Tyrannosaurus either, I just don't think of it as a super dinosaur, instead I think of it as a dinosaur with limitations.
I would say you think of it as a limitation with dinosaurian attributes ! :D

BREAKING NEWS : others dinosaurs have TOO limitations !
Trex would bite spino if it came near, and spinosaurus is not agile at all please don't tell me its going to dodge the trex bite.
So Tyrannosaurus is going to just suddenly bite the Spinosaurus like a ninja strike? Really?

And also, Spinosaurus is visually much larger and would intimidate the Tyrannosaurus, giving the spinosaur a psychological advantage, also it means that Spinosaurus would more likely be the aggressor, not Tyrannosaurus.

And the gape of Tyrannosaurus, being relatively low due to the jaw muscles being more adapted for powered bites than jaw opening, limits the areas of Spinosaurus' body that it can effectively bite.

Spinosaurus: Bigger, possibly stronger, more intimidating, possibly faster.

Tyrannosaurus: More advanced; brain, eyesight similar to that of an eagle, bite (35,000-57,000 N) , better designed to tackle large prey, better dentition for fighting large dinosaurs which might aid it against Spinosaurus, thicker skull and "frame".

Guess T.rex wins IMO.

That's all I can think for now and no I am NOT biased. I hate biased people.
"More advanced" doesn't mean anything when they're only very distantly related. They can't be compared like that because they evolved differently. Intelligence doesn't really play a role here as animals generally fight with instincts, not intelligence. Eyesight isn't really an advantage here.

And it's pretty hard for Spinosaurus to be faster than Tyrannosaurus, considering the size difference, but speed isn't much here as this is a fight, not a race. Agility is the advantage that is usually mistaken for speed, but it's not much of an advantage in fights between creatures of this scale.

Just because spino is slow and can't dodge it does not mean that the trex would do it ninja like. Spino on the other hand can't ever get a good bite because of it's jaws and its not agile the only real weapon it has is power and its claws.

Spinosaurus can get a good bite, it's jaw structure actually allows for a decent bite force, check out the the thread "Spinosaurus bite force", it's opportunities for that are quite limited though. Also, it can dodge by rearing up, placing it's head and neck out of Tyrannosaurus' reach. Spinosaurus isn't going to be moving at slow-mo, how would it catch swimming fish then if it did?

The claws can only be used even slightly effectively if the dinosaur rears up, however, it's overall body strength should give Spinosaurus the advantage.

And btw, Tyrannosaurus' only real weapons are it's head and it's jaws, and the jaws are limited by their gape against a larger opponent, the battering ram-head is going to be Tyrannosaurus' best weapon here, too bad for the tyrannosaur, it has less strength than it's opponent.

Tyrannosaurus isn't going to be very agile here either, neither of them are going to run circles around the other.

They do, that's true, but the level of their limitations are different, and it just so happens that there are dinosaurs with higher limits than Tyrannosaurus.
Example: A Shantungosaurus' strength limits are much higher than that of a Tyrannosaurus'
Now that becomes ridiculous.

Some dinosaurs have higher limitations than Tyrex ? What limitations ? What is true is that in the biting department, Tyrex put to shame any other carnivore. That's a limit !
How is the idea of Tyrannosaurus being surpassed ridiculous? Or is that meant to address the first part of my post? If so, a limitation isn't exactly something which can have the attributes of a living creature.

And about the biting department, megalosaurids have skulls with a greater mechanical advantage than tyrannosauroids. Torvosaurus and/or Edmarka could possibly have rivaled if not exceeded Tyrannosaurus in the biting department, with the combination of larger skulls and higher mechanical advantage.

Also consider that there may have been an undiscovered theropod with an even higher bite force. The possibility of a theropod with a more powerful bite than Tyrannosaurus shouldn't be dismissed.


At now, it is absolutely dismissed. Where the f*** comes your claim of Torvosaurus or Edmarka surpassing Tyrex in the biting department now ? rolleyes From you ? lol


Manabu Sakamoto :
Megalosaurs (including Torvosaurus) are only known from partial skulls so it would be extremely difficult to estimate mechanical advantage accurately, even more so for bite force. Having said that, mechanical advantages calculated for Eustreptospondylus and Dubreuillosaurus (both preserve more skull elements) are comparable if not higher than that of T. rex (Sakamoto, 2010). But like Mike's already mentioned, T. rex has other features that indicate that it had larger, stronger jaw muscles compared to megalosaurs, maybe giant carcharodontosaurs like Carcharodontosaurus and Giganotosaurus, and DEFINITELY Spinosaurus.

There's no bite force known for Spinosaurus jokerman. But :

In order to estimate bite force with any reasonable confidence, we'd need to have a rough idea of how much jaw muscles Spinosaurus had. Unfortunately there are no good cranial materials to reconstruct jaw muscles in Spinosaurus - the bits at the back of the skull where the muscles would have attached are not known for Spinosaurus. Therefore we won't know for sure.

However, we can fairly confidently assume that Spinosaurus would have similar skull proportions to those of close relatives like Baryonyx or Irritator. These theropods had long narrow skulls with not much space for jaw muscles. From what we know of Spinosaurus skull materials, we can be sure that it also had smallish jaw muscles (for an animal of that size).

Extrapolating from size estimates (I presume body size, e.g. body mass, body length, whatever) would not give you a good estimate for Spinosaurus, for the very reasons I outlined above, i.e., spinosaurs had smaller jaw muscles compared to other theropods of similar sizes. Using body size will grossly overestimate bite force.

And now you shut up again you joke.

And actually, bite is the main weapon for all large theropods. Stop to envision theropods as Transformers you joke. I don't know how old you are kid, but think like this, you'll never be a professionnal paleobiologist for sure !

Spinosaurus is inferior in fighting skill, bite force, and tooth design. But it was roughly twice the size of Tyrannosaurus and overall 1.5 times as powerful, so it wins quite easily. Tyrannosaurus's main weapon, its bite, would not be too effective on the large bodied Spinosaurus due to its small gape. If we assume the sizes are 14t for Spino and 6.5t for Tyranno, the result is IMO 90/10 Spinosaurus.

You obviously want to stick to the idea of Tyrannosaurus having the top bite force, that's sensationalistic mainstream belief. What Sakamoto meant is that it's unclear, Torvosaurus' bite force can't be calculated with certainty. You probably didn't notice that I said "could possibly have rivaled if not exceeded", meaning that it's a possibility, not a solid fact.

But you do like putting words in my mouth, do you? Then you have the gall to call me a "little biased fanboy kid" for it. Therefore, I edited your quote so that insult is directed towards you, not me.

I'm not little at all, I'm not a kid either, and I'm not a biased fanboy at all.

There's no need to speak to a doctor about it, I don't have a problem with Tyrannosaurus, it's you that has a problem with anyone who doesn't try to defend Tyrannosaurus' "title"...

The arms of cats and humans are NOTHING like those of a theropod. First of they are WAY longer in proportion to their size. Secondly they are more flexible and have more versatile movement. And lastly they are placed in a convenient position.

And as I said, not functioning the same way you know from cats doesn't mean not being weapons at all

Hunting smaller prey like fishes? Ritual fighting? Ripping animal carcasses into swallowable chunks? All three? Not every weapon on an animals body was developed for serious fighting with similar sized animals.

OK, lets see, hmm, what were rexy's jaws for....ritual fighting-YEAH!, and of course carcass dismemberment

Quote:
 
What you don't seem to get is that these claws would minor lacerations on animal as large as trex and will do little to contribute in the fight.

And what you don't see is that lacerations are usually caused by something sharp and the claws of spinosaurs are meathooks, not knives.

If spinosaurus got a hold on its opponents with these arms, they will not deal that much direct damage (still much considering their size), but they won't let go and the strenght of spinosaurus will do the rest. End result: rexy gets thrown over and dies.

Head and jaws is all it needs to injure the spinosaurus.

with its arms or body or whatever, not the arms alone


So I suppose a tyrannosaurus could wrestle down a hypothetical one or two ton animal down with its tiny ass arms because its heavier?

and I'm not so sure whether both arms really weighed less than rexys head...


Trex's head is like half a ton, I seriously don't think spinosaurus's short arms are that damn heavy.

And as I said, not functioning the same way you know from cats doesn't mean not being weapons at all


Are they weapons? Yes. Are they effective on large animals? Probably not.

OK, lets see, hmm, what were rexy's jaws for....ritual fighting-YEAH!, and of course carcass dismemberment


Wow you're doing this again.... Tyrannosaurus's head is about one eighth of its length and its jaws have been proven to easily crush the bones of most animals so its obviously used to kill. Spinosaurus's arms are larger than most theropods but are still small for their size and we have evidence of these claws being used to kill large animals.

Why do you keep making these horrible comparisons?

Seriously a spinsaurus's claws would at best give trex some nasty lacerations but that would hardly effect the health of the animal in a the short time span these two would be fighting those its a non factor, why is this concept so hard to grasp?

I'm not biased against Tyrannosaurus either, I just don't think of it as a super dinosaur, instead I think of it as a dinosaur with limitations.
I would say you think of it as a limitation with dinosaurian attributes ! :D

BREAKING NEWS : others dinosaurs have TOO limitations !
Trex would bite spino if it came near, and spinosaurus is not agile at all please don't tell me its going to dodge the trex bite.
So Tyrannosaurus is going to just suddenly bite the Spinosaurus like a ninja strike? Really?

And also, Spinosaurus is visually much larger and would intimidate the Tyrannosaurus, giving the spinosaur a psychological advantage, also it means that Spinosaurus would more likely be the aggressor, not Tyrannosaurus.

And the gape of Tyrannosaurus, being relatively low due to the jaw muscles being more adapted for powered bites than jaw opening, limits the areas of Spinosaurus' body that it can effectively bite.
Just because spino is slow and can't dodge it does not mean that the trex would do it ninja like. Spino on the other hand can't ever get a good bite because of it's jaws and its not agile the only real weapon it has is power and its claws.
Spinosaurus can get a good bite, it's jaw structure actually allows for a decent bite force, check out the the thread "Spinosaurus bite force", it's opportunities for that are quite limited though. Also, it can dodge by rearing up, placing it's head and neck out of Tyrannosaurus' reach. Spinosaurus isn't going to be moving at slow-mo, how would it catch swimming fish then if it did?

The claws can only be used even slightly effectively if the dinosaur rears up, however, it's overall body strength should give Spinosaurus the advantage.

And btw, Tyrannosaurus' only real weapons are it's head and it's jaws, and the jaws are limited by their gape against a larger opponent, the battering ram-head is going to be Tyrannosaurus' best weapon here, too bad for the tyrannosaur, it has less strength than it's opponent.

Head and jaws is all it needs to injure the spinosaurus.
Spinosaurus is almost 2 times heavier than T.rex. How the hell is it going to injure an opponent that big? T.rex's bone crushing bite means nothing in this fight if the opponent is too big.

LOL@ broly.
Your notion on Torvosaurus is not supported by any evidence. Again your bigotry towards certain opinions and animals is astonishing. I think you showed signs of betterment but I guess I was wrong.
Please, can you say me if it is wortwhile to discuss with this guy ? I have never seen such a bad faith among dinos forumers...
