Giganotosaurus carolinii v Tyrannosaurus rex

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.

Sue or Trix vs MUCPv-Ch1- Sue or Trix wins around 70 percentages
Sue or Trix vs MUCPv-95- it is 50/50
MUCPv-Ch1 vs Tristan or CM 9380- CM 9380 or Tristan wins 60 percentages
MUCPv-95 vs Tristan or CM 9380-MUCPv-95 wins 70 percentages
MUCPv-95 vs other t rex as Stan and AMNH 5027-MUCPv-95 wins 80 percentages
MuCPv-Ch1 vs other t rex as Stan and AMNH 5027- T rex wins 50-55 percentages

t rex vs giganotosaurus at max size it is 50/50
t rex vs giganotosaurus at normal size it is 50-55 for t rex

Does everyone here keep the same opinions they had before? Any new opinions?

I don't think that the figth will be 'decided by the first bite',as I used to think several months ago.The animals,in my opinion,aren't going to do one or two bites and end it,unless they land a lucky bite on a major vein.

There seem to have been a number of giant allosaurids approximately equal in size-Giganotosaurus, Mapusaurus, Tyrannotitan, and Carcharodontosaurus. For those favoring Tyrannosaurus, what allosaurid would you rate as T-rex's most formidable adversary?

All of the carcharadontosaurids you listed would be an equal match for a t.rex in my opinion.

As far as I know: Carcharodontosaurus is the overall biggest of the bunch, but Giganotosaurus neck, head and torso are more robust. Tyrannotitan is similar to Giganotosaurus but smaller, and Mapusaurus is the most gracile.

Yup, basically it. Thanks for the quick summary. :D

The idea of the gracile Mapusaurus mostly came off a Sinkonnen's skeletal. That skeletal has several issues, but one of the most noticeable is its slenderness, which, I think, isn't proven by anything. Also, we can hardly know wheter Giganotosaurus had a bulkier torso than Carcharodontosaurus' since we don't know the latter's. Basically, Giganotosaurus is the largest known Carcharodontosaurid according to *official* estimates; Mapusaurus and Carcharodontosaurus were probably in its league though. At either, we cannot say much about visible differences between these 3 large Carcharodontosaurids. They were most likely very similar to each other both in size and appearences, with some differencies we can't see through the remains.

I wonder if a 8000 kg+ T Rex could crush the skull of Giga? By placing close to 6 ton of pressure and 12 inches banana sized teeth on the rather hollow and gracile structure of Giga's skull, the fight could end very quickly if that's the case.

A Giga skull it too big to fit in a T. Rex jaws.

Pretty sure T Rex's gape size is large enough to fit the width of Giga's skull. T rex's skull is more than a third wider than giga's.

Well you'll be surprised to learn it's not big enough.

Tyrannosaurus can't fit the entire skull in, obviously, but it should definitely be able to crush whatever portion it manages to get a hold onto.

Indeed Ausar. Also there's no need to crush the entire skull at once, by crushing a portion of it should be enough to cripple giga in a fight. Head bite is also one of the fastest way to kill and definitely easier to get a hold to than either the neck of throat region.

I mostly disagree, Sue the tyrannosaurus was taller (by a bit) than the giganotosaurus holotype , giganotosaurus is likely anything heavier than tyrannosaurus. In my opinion it is a 60% chances of winning for rex and 40% chances for giganotosaurus
