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.

??? I posted here, but my post didn't apear. Strange.

Anyway: Giga wins this. It's bigger, more agile and can cause more serious injuries much quicker using those gigantic scicors. Giga wins 60% of the time.
How the agility helps in the match? Also Trex can causes more serious injuries easily and it is possible for Trex to crushed Giga's skull. Giga wasn't much bigger than Trex as Trex is quite heavier than Giga. Trex wins 70% of the time.

Giga wasn't faster and much more agile. Giga had only slightly longer femur than T.rex,s , while its tibia and metatarsal were much shorter. That's proves that T.rex could be faster.

T.rex (sue) Giga (MUCPv-CH1)
Femur: 138/140 cm 143 cm
Tibia: 124.5/125.3 cm 112 cm
Metatarsus 67.1+ cm 50-52 cm (estimated by scaling closest relative)

Sue would have 22.6-27,6 cm longer legs than Giga holotype. So T.rex was certainly taller. MUCPv-95 legs were not found yet, only there is its left dentary. The size is still unknown, the length 13.2 m and weight 6.2-10.8 tons are just estimated values, if it was 8 % longer and taller than MUCPv-CH1.

1: Agility can help you dodge attacks, you know.

2: Nope. T.rex had to bite down and rip of. That is a dangerous thing to do with a large animal. Giga can just walk by hack down and remove a bigger piece of meat, in less time, with less effort and with less danger. Why else do you think it had meatslicer jaws?

3: IF it can grab it and has the time to put force on it. And that's the problem. Giga's skull is to big to bite it normaly. T.rex would have to twist its neck into a position that would come close to breaking it. With a bit of efforrd Giga could break of of the grip and kill its attacker by using all its power to twist its head in the same direction, causing the Rex's neck to break.

4: Ehhhh... Last time I checked Bigger = Heavyer. So basicly you said it was bigger, yet it wasn't at the same time. ^o)


@7Alx1: I never said it was faster. I also never said it was much more agile. I said it was MORE agile tough.

@7Alx2: No, it wasn't MUCH shorter. Only like 8% And since It's femur was 5% longer, there's only a 3% difference left.

@7Alx3: No. That is not certain at all. Thier body proportions aren't the same. Perhaps Giga had a a very tall spine while we just don't know it yet. (The holotype could've been a mutant.) Even if it didn't. You can't be certain. Perhaps the Holotype was tiny for its kind and normal Gigas can become 30% taller.

:angry: 30 % taller ? Are you kidding? Stop fanboying !

I made size comparison using G.Paul's Giga and Harman's T.rex. I know t.rex specimen is AMNH 5027, but i made it in sue size. While Giga is based on size of MUCPv-Ch1 (~12.5 m). I will make another size comparison with MUCPv-95.

Some species have a big size difference between genders. Male Crocodiles can become more than 50% larger than females. Besides, I wasn't saying they COULD become 30% taller. I was just saying it's posssible.

T. rex would win. Yes, Giga is a bit bigger, but their skulls are around the same size. And T. rex's bite was very strong, suited to crushing bone, while Giga's was more suited for tearing out chunks of flesh, which is useful for hunting sauropods but not necessarily for one on one combat.

Ehh, you know Giga's skull was like 1.25 times the size of T.rex's right? That's not around the same size.

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.

Once again, Giga had definitely more slender build. So there is not possible that it would be heavier than T.rex, unless it was 14-15 m. But new studies say Giga was only 12.2-12.5 m, maybe 13.2 m. Plus how could use its claws. The arms were too short to fighting, longer than rex's though, but still short.

I have a question regarding the dinosaurs weights:

Being that Tyrannosaurus is a Coelurosaur, wouldn't it have light, hollow bones? Especially when compared to Giganotosaurus, which had denser bones due to being Allosauroid.

How would T-rex weigh more then Giganotosaurus if its bones were lighter? Is it because of more muscle?

Like i said earlier T.rex had thicker bones and more massive body.

1: Oh, come on! Your just like the Spino haters now! True, it's more slender, but not that much slender! Look at the bones you posted in that picture! They're actualy pretty chunky.
2: You can't say that. We have 2 specimens to go by. With T.rex we have 9 specimens we can look at, we know it's avarage size. With Giganotosaurus there is no such certainty. But seeing as we have a specimen possibly more than 13 meters long and one around 12.5 meters long, 13 meters seems like a good estimate for the AVARAGE size. Since you are always looking at Sue, I think you should use a Giganotosaurus that's 13.5 meters long AT THE VERY LEAST.
3: No, they're not to small. If we'd use the position the T.rexes mated in WWD and replace the male with a Giganotosaurus (And make him larger, of course.) it could slash or grab the back. This could be used in combination of its jaws: Slicing holes in the victim while keeping it from strugling to hard.

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.
