Carcharodontosaurus saharicus This huge meat eater was 45 feet long (5 feet longer than T-rex) and weighed 8 tons, making it one of the largest carnivores that ever walked the earth. This African carnosaur had a gigantic 5’4" long skull and enormous jaws with 8" long serrated teeth. It walked on two legs, had a massive tail, bulky body and short arms ending in three-fingered hands with sharp claws. Carcharodontosaurus is one of the longest and heaviest known carnivorous dinosaurs, with various scientists proposing length estimates ranging between 12 and 13 m (39-43.5 ft) and weight estimates between 6 and 15 metric tons. Its long, muscular legs, and fossilized trackways indicate that it could run about 20 miles per hour, though there is some controversy as to whether it actually did, a forward fall would have been deadly to Carcharodontosaurus, due to the inability of its small arms to brace the animal when it landed. Carcharodontosaurus was a carnivore, with enormous jaws and long, serrated teeth up to eight inches long. ![]() 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.[1] 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. ![]() _________________________________________________________________________________

the claws could do serious damage if they hooked into it´s throat. Giganotosaurus was scientifically estimated to reach 50km/h, that´s faster than rexy. The gape must have been enourmous because they were adapted tu hunt sauropods. I highly doubt that at tearing flesh T rex´s teeth were anywere near as effective as carcharodontosaurus´. otherwise, they woulodn´t ahve evolved like they were. If carcharodontosaurus was able to inflict deadly damage to sauropods, it wouldn´t have problems doing so to T rex. even if it´s not as good at crushing bones, it´s naive to think T rex could survive a bite from it. |

Could you give a link for the speed of Giganotosaurus? I would appreciate it. BTW it would be way faster than Acrocanthosaurus. |

I know, Acrocantosaurus seems quite slow. Here is a paper about the speed of Giganotosaurus: http://app.pan.pl/archive/published/app46/app46-193.pdf |

I hope I don't bother anybody by bumping this semi old thread, but I find this hypothetical conflict amongst one of my favorites. I favor tyrannosaurus despite Carcharodontosaurus's size advantage, as it has a much stronger bite and seemed to be more robust; however I may be biased as tyrannosaurus is my favorite animal.

Yes, I will favor it over sauropods, modern day armies, and aliens! In all seriousness please post something relevant to this thread mr broly. |

Carcharodontosaurus wasn't bigger than Tyrannosaurus, Carcharodontosaurus had a 1.6m skull while Giga had a 1.95m long skull.

True, however tyrannosaurs seem to be extremely durable animals. http://www.museum.manchester.ac.uk/yourvisit/galleries/stanthetrex/ http://news.discovery.com/animals/tyrannosaurus-rex-teens-battle.html A bite from a trex will kill/maim instantly, a bite from carcharadontosaurus would have to be better placed to get the same effect.
An extremely minor advantage in my opinion. It would have to stand right next to tyrannosaurus and rear up to make use of its small arms. |

Tyrant, don´t take broleywhatever serious, he is accusing everybody to be a T rex fan, as long as he isn´t a hater. I share his oppinion on some points, but I´m not accusing somebody to be a fanboy as soon as he supports Tyrannosaurus. |

Thanks I appreciate the concern, but you'll find that it takes a little more than a fanboy accusation to get under my skin :). Now that we got the spam posts out of the way, I think its time for a healthy debate eh? |

Not really, but it seems like Carch could open it's mouth quite far:
