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. ![]() _________________________________________________________________________________

those claws wouldn´t be nice to get grabbed with. They may be not a deadly weapon themselfes, but as frequently the case among carnivores, they might fasten onto each others skulls, and then T rex´s neck would probably be in reach. I think at the right place, the claws could do considerable damage. As to the result, I think it would be fairly balanced, depending on which one gets the first bite. |

Yea. They are surely not like actual weapons such as a raptor's sicke-shaped claws, but they could still do a good amount of damage if they hooked into the flesh of an opponent. |

I´m not so sure whether raptor claws really were used to disempowel. The claws that I know (I´ve got a replica of a velociraptor claw) arne´t sharp, tough the layers of ceratine could have changed this (but they could have done this with carnosaur claws as well so...). They could have been used like a dagger to puncture internal organs |

That's what I meant. The were used to slice open the bellies (I just say "bellies" to sound more gorey :P) of prey. That is surely a weapon. |

Carch can grow up to 13-14m, against a 12m rex, it's a clear advantage in size! Too it had longer arms, sharper teeth and could open it's mouth more further(some people suggest it to be also faster). 55/45 in favour of Carch. |

Carcharadontosaurus has teeth and jaws that can slice through flesh easily, and a wide gape to go with it. Bite force isn't everything. Carcharadontosaurus also has a size advantage and functional arms with sharp claws. Carcharadontosaurus wins |

How big do you think Carch was? |

In any case, unlike many fanboyish videos say, it was larger than Rexy. Some of them have stated it to be 11-12m long (with a 1,6m skull for C.saharicus and an even 1,75m long one for C. iguidensis, this animal ought to be larger than 13m) just to make rexy look bigger in comparison. |

Sorry for the late reply, anyway, I don't think the functional arms of Carcharodontosaurus would be much of an advantage. I don't see how they could be used to fight without getting in like 1 meter. |

For example if the carcharodontosaurus rams the t rex with its body or if it bites it´s skull to dodge it´s attacks. |

I don't really understand what you mean, Theropod. I think arms shouldn't really be taken into consideration in terms of huge Theropods. |

I mean that theropods are know to bite each others skulls, and if carch bit Rexys skull, it could get glose enough to claw the troat and possibly severe a blood vessel. There must be a reason for those clows. As carcharodontosaurs likely hunted sauropods, holding onto it´s prey could have been the purpose. That´s what I meant with ramming T rex. |

Ah, I see. But, it would have to come within incredibly close range as the claws are still small. |

The claws aren´t small, with ceratine they ought to be >30cm long or so. But of course it needs to come very close. Still, the claws aren´t worthless. |
