Giganotosaurus carolinii
Giganotosaurus ("giant southern lizard"), was a carcharodontosaurid dinosaur that lived 93 to 89 million years ago during the Turonian stage of the Late Cretaceous period. It is one of the longest known terrestrial carnivores, bigger than Tyrannosaurus, but in length and weight, smaller than Spinosaurus. Although longer than T. rex, G. carolinii was lighter and had a much smaller braincase that was the size and shape of a banana. A well-developed olfactory region means it probably had a good sense of smell. Titanosaur fossils have been recovered near the remains of Giganotosaurus, leading to speculation that these carnivores may have preyed on the giant herbivores. Fossils of related carcharodontosaurid fossils grouped closely together may indicate pack hunting, a behavior that could possibly extend to Giganotosaurus itself. he holotype specimen's (MUCPv-Ch1) skeleton was about 70% complete and included parts of the skull, a lower jaw, pelvis, hindlimbs and most of the backbone. The premaxillae, jugals, quadratojugals, the back of the lower jaws and the forelimbs are missing. Various estimates find that it measured somewhere between 12.2 and 13 m (40 and 43 ft) in length, and between 6.5 and 13.3 tons in weight. A second, more fragmentary, specimen (MUCPv-95) has also been identified, found in 1987 by Jorge Calvo. It is only known from the front part of the left dentary which is 8% larger than the equivalent bone from the holotype. This largest Giganotosaurus specimen is estimated to represent an individual with a skull length of 195 cm (6.40 ft), compared to the holotype's estimated at 1.80 m (5.9 ft) skull, making it likely that Giganotosaurus had the largest skull of any known theropod. Giganotosaurus surpassed Tyrannosaurus in mass by at least half a ton (the upper size estimate for T. rex is 9.1 t). Additionally several single teeth, discovered from 1987 onwards, have been referred to the species.

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. 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.

So comparing the bite of a giganatosaurus and t-rex will be like comparing the bite of a crocodile and the bite of shark in some way?
Crocodiles don't have ziphodont teeth, so eh.

It's more like a hyena or wolf if anything.

Yeah no just because it has blade like dentition doesn't mean it can't damage the spinal column of another animal as illustrated by this in Auffenberg's book

"As in other carnivores, cannibalism is most common during the periods of high population density. The usual ecological separation of size groups in V. komodoensis tends to keep densities uniform over fairly large areas. However, this density uniformity breaks down during feeding aggregations, when various-sized individuals are crowded together in rather small areas. At these times aggression is common (Chap. 12). Though such aggregations provide opportunities for cannibalism, we have never observed it under those circumstances. However, 19W killed two smaller oras (18W and 27W) and undoubtedly would have eaten both if he had not been frightened off. In both instances the smaller lizard was in Trap 1 when 19W entered it. Tracks on the ground in both cases suggested that the smaller lizards tried to get away but were apparently cornered, seized, and killed. In both cases a dead bait was available to 19W, but it was ignored in favor of the smaller, live lizard. In one instance 19W was frightened while he was still in the trap, and he left the dead lizard immediately and tried to scramble out of the trap. In the other case, 19W trapped 18W in the trap release box. The struggle there was so fierce that a hinge of the release door was sprung and the 4-mm nylon cords holding the door closed were torn loose. The larger ora then apparently dragged the smaller one through the box and out of the trap. There the widely splattered blood indicated he had thrown the lizard from side to side very violently. (The same technique is also used on smaller prey by other varanid species [Loop, 1974].) It was at this time that the vertebral column was apparently severed and the abdominal cavity opened by a massive wound extending across the belly from side to side. The carcass was being dragged into the brush as we approached the trap. While we spent a few minutes reconstructing the events on the basis of the tracks and signs, the large ora had eaten the viscera. He left the carcass when he saw us as we trailed him into the brush. Lizard 27W also had its vertebral column severed, probably by the same technique. It is clear that under certain circumstances a large ora will attack and eat any smaller ora it can manage to corner. This probably happens most often in ora burrows and along earth and rock cliffs. Overall density of oras and other potential food resources in the general area are obviously important factors. Cannibalism is largely restricted to both the very young and the old. The former are captured alive and eaten, but remains of large monitors are probably the result of scavenging (see Chap. 11). The pattern of cannibalistic activity being largely restricted to larger specimens is identical to that found in Crocodylus niloticus by Cott (1960)."

Last time I checked it's a giga vs t rex fight not a komodo dragon brawl. T rex's neck is too thick and well protected in this instance for giga's teeth to instant kill it.

And The Komodo dragons neck isn't ? Give me a break, it's muscular and thick with tough sales all over it. And the Komodo's teeth are fairly similar to the carnosaur so there point stands.

Well the whole ramming thing was actually portrayed in the docu Dinosaur Revolution, episode 4 where two t-rexes rammed each other both using the skull and the shoulder.
https://www.youtube.com/watch?v=PCtZCi-OIBU
The story writers of Dinosaur Revolution must not have been aware of the fact that S-shaped necks aren't the best absorbers of horizontal force impacting the head. Or the fact that there are no real headbutting adaptations in tyrannosaurids. Or any "shoulder checking" adaptations in them either.
OK I'll trust your expertise for now since you're pretty well informed in this forum. But in a close quarter fight there will be body contact right? So the stronger animal would eventually overpower the weaker one by doing however ways possible be it body slam, tackle, throw or thrash. Crocodiles don't strictly bite one another in a fight, they bash their heads against one another, so in some way the stronger animal would inflict more physical damage to the weaker one and as you get damaged more, the better chance for your opponent to win isn't that right?

Of course not, it's nowhere near as powerfully and heavily built as a t rex's lol, are you kidding me. I'm talking about in proportion.

You are totally missing the point here, the dentition of carnosaurs are specially adapted to cutting through large amounts of muscule, skin, fat, etc. It will saw through the neck tissue and break the spinal cord. That is for sure. But it dosent even matter honestly, so what UF you think it won't break the neck bones? It will cut through all the neck tissue like a hot knife through butter abd that alone will kill it instantly or in a few seconds. Why do you think slitting Someone or something's throat is such a deadly abd effective way of killing? The gigas bute will be very similar but a hell if a lot more gruesome and gory.

irrelevant to the fact you're trying to say that just because it has blade shaped teeth it cannot do any damage to the bone, or sever a spinal column in the ora case. try harder with your nonsense.

I know it's specialized for cutting but it's just not enough to kill it instantly on the neck region, overtime maybe, certainly nowhere near as fast as you described it. Giga's teeth aren't that long and rex's neck is not that thin.

@cerato, he is already trying pretty hard.

You are honestly telling me that the t.rex is going to tank a full on bite to the neck from giga? That's BS and you know it. A guy and still slit your throat and kill a very fat man with a fat neck with a 2 inch blade. Yes it will die as quick as I described it, it will have its jugular and veins severd. It will die very very soon after. Show me an account if an animal having its neck totally ripped open and spinal colum snapped and living.

@Bonecrusher,
because cutting through flesh in a vital area and in turn inducing blood loss is not a quick death at all right? maybe not instantaneous but its not going to be a prolonged period of time at all.

It might be instantaneous or very close to it, having your sipinal colum severd and your entire neck severd will wuick you pretty quickly. And you (bone crusher) say that it won't cut the neck because if it's almighty neck with out realizing it killed sauropods with much thicker proportions then the t.rex's neck.

The question is which dinosaur will get to the other's throat first, not if such a bite would be fatal. It would be in any case, just look at these jaws. The arms are a non-factor, they would most likely face-bite each other until one succumbs and offers a better place to bite.

Who would have the easier time biting his opponent in this fight? Giganotosaurus had apparently a wider jaws gape which could probably help him. Is there any data about their neck's flexibility? Also, was giganotosaurus able to grapple with his arms or they were too small to be useful in a fight (like t-rex)?

I guess, but personally, I'm not so sure if there's really a difference in strength here.

But why not? Their morphology clearly shows t-rex being the more powerfully built one.
