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.

Darkgricer has never changed at all and don't do his research as usual.

Giga wasn't heavy than a Trex as it is a little taller and a little longer but that doesn't mean Giga is bigger and heavier than a Trex.

So Giga' fragile skull is too big for a Trex to crush? Also do you think Giga can kill a robust Trex through breaking its neck? Giga wasn't built for combat while Trex was a combat creature.

Giga's skull wasn't that robust or sturdy as Trex's skull.
1: Oh, please. You want to apply T.rex's new weight, wait for tests to be done for Giganotosaurus. Until there's new weight for Giga, Giga is bigger.

2: No. But it's to big to bite. T.rex can't bite a head it ifs bigger than it's jaws. The only way it could bite it is by twisting its head, allowing Giga to finish it off instantly. You see, if the T.rex twists its head and bites Giga's, Giga could bite it's opponnets head as well, meaning it to has a grip on it. Then it could use its claws to get extra grip. Then, using its neck and arm muscles, it could twist the already twisted head to to point where the neck breaks.

3: Like that matters. Bite force helps. But giant flesh scicors help just as much.
rolleyes

Giga's just lighter than Trex due to less dense in the bones. The new weights of Trex was never applied to Giga or other theropods as the article has never mentioned of them.

Trex has dealt with other trex so why Giga should be different? I find it unlikely that Giga could broke Trex's neck and would use it's pathetic claws to twisting Trex's head.

Also Trex dealt with other trex and they often have scars on the skulls. Trex's teeth has serrated edges which are no different from Giga's teeth, just thicker. I see no evidence that Giga's head is too big for a Trex to bites on and crush the skull.

You know it's fun to see you get wrong all times and we have to correct you all times.
Oh, god. You haven't changed a bit. That's not a good thing, just telling ya.

1: I basiclly meant to say: Wait until there's some new weights for Giganotosaurus!

2: The difference is, T.rex has a head that's 25% shorter. For a head, that's a big difference.

3: Yet there's no evidence that they broke each other skulls in a fight to the death, smarty. rolleyes The fact that there are scars on the skulls doesn't mean they actualy put a snout in thier mouth. It's just that some teeth went with enough force to scrape of the bone. rolleyes

4: I think you meanth to say me insteed of you, seeing you basicly proved you're wrong by saying that I'm wrong about the whole bite head thingy, yet there isn't any evidence that they crushed each others skulls with thier bites in a fight to the death.

Trex's skulls are robust, yet there are scars all over on Trex's skulls. Giga on other hand, have fragile skull which isn't sturdy at all makes easier for a Trex to crush Giga's skull.

It doesnt matter if Trex's skull is "25"% smaller than Giga's skull.

Twisting a neck with pathetic arms of Giga, that's just unrealistic as usual when it comes from you.

1: Easyer! But a skull is a skull. And a skull is the second toughest thing in your body. (Or at least, that counts for humans. Not sure about Dinosaurs, tough.)

2: Yes it does. It means it's easyer for T.rex to get a grip on it's own skull than on Giga's skull.

3: Oh, please! Seriously? You think I said Giga was able to twist T.rex's head with it's arms alone? No, I didn't. I said it could do so by using it's head AND claws at the same time, Smarty! rolleyes

And why it is hard for a Trex to chomp on a Giga's skull which isn't much bigger than a Trex's skull, not mentioned that it was less robust than Trex?

Giga' skull wasn't robust as Trex's skull which you have trouble to grasp around the fact.

So Giga's jaws and arms can snap a Trex's robust and sturdy neck?

If it's possible that you can quit names calling?

1: Because it's to big for it's mouth, maybe. rolleyes

2: I know, and it doesn't matter. IT'S A FRIGGIN SKULL!

3: They can twist it to the point where it snaps, yes.

4: Sorry. People like you always call me smarty, so it feels good to call someone smarty.

So Giga's relatively small arms that were probably best suited for holding onto prey could twist T. rex's neck when used with its head? Giga couldn't possibly use his arms and head on T. rex at the same time. It's physically impossible.

Not entirely. If it rear up a bit and grabd T.rex's snout it could also grab the back of the head with it's jaws if posed correctly. Then it could use it's strenth to twist it, just twist it, ow!

Giga' skull wasn't that big as Trex can easily chomp on Giga' skull with no problems, unless Giga is a Godzilla.

Look at Giga's skull and look at Trex's skull in the picture and tell me what you see. I see a less robust skull of Giga as it wasn't built to hold a large struggling animal like Trex.

It's impossible for a Giga to twist a Trex's neck with jaws and pathetic arms as Trex is quite robust and muscular while Giga is less robust and lighter.

Yeah and you were banned from old forum for calling names.

With the small arms and less robust skull against a robust animal? Trex isn't a giraffe or ostrich.

1: Yeah, I can see it try. First it will need to dislocat its lower jaw like a snake. UNLESS it wants to risk having it's neck broken.

2: Yes it's claws are great grapling hooks.

3: No, just no. If it uses ALL it's power from its neck and arms, it's gonna break a neck. Giganotosaurus was a very large animal. Size equals strength.

4: Which I don't quite understand, as I didn't call anyone something extreme.

!. Why Trex need to dislocate the lower jaw like a snake? It don't need to dislocate the jaws to chomp on a Giga' skull WHICH isn't larger than a Trex's skull, not mentioned that it wasnt robust skull. Also Trex dont have to be worried about have its neck broken as I told you its physically impossible for a Giga.

2. Giga's arms and claws were pathetic for grappling against other theropods and have no role in the match.

3. It's physically impossible for a Giga to break/snap/twist a sturdy Trex's neck through arms and jaws. Giga wasn't VERY larger than Trex and Giga doesn't have any size advantage in this match since Giga is just a slightly taller/longer but not that much. Lighter and less robust theropod v.s sturdy and heavier theropod so I don't see what you were talking about Size equal strength?

4. You have warned too many times from mods and call us Trex fanboys for NO reason.

Nein...ZE BEAUTIFUL LOGIC...it is being ignored! Such BLASPHEMY!

OK.

Tyrannosaurus wins. Giganotosaurus has virtually no advantage except for a larger gape. Tyrannosaurus is taller, smarter, faster, has binocular vision and a deadlier bite. Weight has no bearing in this matchup, so forget about it. They're not sumo wrestling.

An allosaurid design does not indicate agility; also, keep in mind that tyrannosaurus has longer legs and broader hips for more muscle attachment. Breaking tyrannosaurus' neck? Laughable. How do you break a taller theropod's neck if its neck vertebrae are thicker and the muscles are more developed? Hmm? Oh, and add the fact that you're receiving more than 6 tons of pressure on YO FACE.

Tyrannosaurus had a hinged jaw that allowed it to open its mouth wide enough to take in massive amounts of flesh with a single bite. The scissor-jaw thing is a futile argument. Tyrannosaurus doesn't even need slicing teeth to kill. The bite force alone is enough to rupture and crush vital organs, bones, and blood vessels. However, if you wish to pursue that issue again, here you go:

How's this for slicing?

If Giga defied basic theropod anatomy to somehow bite and twist T. rex's neck as you said, it would leave Giga wide open for attack. And it couldn't twist T. rex' neck without twisting its own.

As DinoLord pointed out, it would mean Giganotosaurus would be reverting to the old, scrapped "tripod" hypothesis that was shown to be inaccurate.

Stop trying to save your argument by twisting known facts about Dinosaur form and function.
