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.

And fairly recently, between vobby any me, I may add. That was certainly among the more interesting discussions I’ve had lately.

so megaladon says her thoughts for rexy they must be joking, but anything aginst rexy is applauded...that is why i stopped replying to the tyrannosaur vs spin. thread, fanboys rip you a new one.I think it's 50/50 here since both have weapons to take the other out at the first chance of a slip up

T rex wins. Easy. Gigantosaurus had horrible eye sight and was clumsy. T rex had some of the best eye sight of all dinos and was very VERY clever. T rex was also fast (not the fastest but fast) so he could get bites in faster than gigantosaurus. But gigantosaurus hunted huge prey and also has a size advantage over t rex. but still t rex wins 60% of the time :P

'Giganotosaurus had horrible eye sight...'
There is no proof of Giganotosaurus having particularly poor eyesight at all.
'...and was clumsy.'
Seriously dude, neither of these theropods will be particularly agile or nimble because they are both so massive.
'T. rex had some of the best eye sight of all dinos...'
Many other predatory dinosaurs also evolved efficient eyesight.
'...and was very VERY clever.'
There is no evidence of Tyrannosaurus' intelligence, scientists have only analysed its visual and olfactory capacities.
'T. rex was also fast...'
So you think an 8.4 ton animal is going to be fast?
'But Giganotosaurus hunted huge prey...'
What the animal hunts is irrelevant when it comes to these kinds of hypothetical fights, evolution is not a ladder.

You don't understand, megalodon is not ridiculed for favoring Tyrannosaurus (I also made points in favor of Tyrannosaurus in some threads). It are the arguments who are criticized, not the position. Be honest, theropod made a post which is right above megalodon's which completely refutes it. He didn't assess eyesight, but it is the same principle as with reflexes/dexterity and the analogies are valid. Intelligence also was discussed often enough.
oh ok i just didn't want another person to feel belittled because i recently saw a seminar at school.It was called Rachels Challange about a girl who was killed in the columbine shooting and it stuck with me,i felt that after seeing it i would try to spread a message she believed which was in a nutshell being nice to fellow man

It's due to the eyes being placed more laterally, although that has a much smaller impact on the outcome than he probably thought.

8.4 tons is just Hartman's estimate for FMNH PR2081, other specimens would weigh less, Hartman also used a quite high density of 0.913kg/l, Hutchinson et al., got at a total density of 0.791 for FMNH PR2081, however with a different model. A net density of 0.8 would be probably better, and so the specimen could be about a ton smaller.

i'm finding it hilarious that your calling me a troll, even though your the randam guy that came out of no where acusing me as a fan boy just because i questioned the seriousness of someone elses post. if you were to sit back and think for a minute, and read the posts that were made before AND after him, you realize his post was irrelevent to how a t-rex would be able to kill a giganotosaurus easily.
your the troll, dude

8,400 kg is still the best estimate available, the fact that it was based on a highly reliable skeletal that corrects all of the mount errors means that its volume estimate is far more reliable too.

I would still use the 8.4 ton estimate for Sue as it is one of the most reliable estimates for the Tyrannosaurid's weight. I am certainly open to any new estimates though.

funny how none of these kids trying to dod-pile are replying ahaha they only attack in numbers! That's the only time they feel the keyboard courage to spew shit and act like some kids opinion is 'fact' or a 'source' even when the topic they do it in is tired and old (also having a definitive answer they all like to dance around because they don't agree with the TRUTH).This can be seen in spino vs rex thread as well, i gave up on it a while ago.no use in having some 15 year olds trying to inflict their internet C-list attempts at humour while agreeing with utter bullshit about an animal that was given god-status from 1 movie lol

arachniKID (emphasized on purpose)
my post isn't even that long, heck, yours was longer. it's just that your attention span prohibits you to reading and comprehending a simple post, just like your not understanding the points made by me, and every other poster
your the one not only trying to push the argument, and bring cussing to desperately prove your points, but also trying to spam a the thread with something no even remotely close to the topic.
unless you haven't notice, this is a debating forum made for MEN and Women to make LOGICAL discussion. if you really think this guy your defending is a kid, it just further the reason why he shouldn't post here. megalodon ignored the points made directly above him and stated the complete opposite. so it's not a matter of opinion, its a baseless and nonsense assumption. so I suggest taking some chill pills, because your the one pushing the topic.

now can we please get back to subject
