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. ![]() _________________________________________________________________________________

Isn't Sue's maximum skull length 153cm? Where did you get 146cm from? |

The figure of 140 cm in Brochus paper refers to Pmx-Qj, Holtz gave 153cm as Pmx-Occ, but I don´t understand how it is possible (Verdugo has posted the info on it), actually it ought to be shorter, so maybe it referred to the crushed skull (it should now be 139cm). The 146cm are the maximum dimension when scaled to the 140cm for Pmx-Qj Brochu gave. |

I´m working on making a dorsal view reconstruction of sue, but that´s a bit difficult due to the crushing. |

Lately this thing with skull lengths has gotten kind of confusing. I've read your blog, now I understand haha Edited by blaze, Jan 2 2013, 01:05 PM.

treu, very confusing. I´m still wondering what 153cm could refer to, as it looks like the figures are excluding each others (when I scale it to brochus measurement even the alrgest dimension of the skull isn´t anywhere near to 1,53m). So I´d recommend keeping in mind there is another measurement for sues skull that might also be correct. |

with the carcha bite force... carcha could´nt got really bad damage to t-rex because rex is more robust than carcha then if t-rex bite carcha with his powerful bite neck would be broken in secs.... |

Are you saying that just because carcha has larger arms is more advanced... evolution and proofs said that T-rex is best predator than carcha.... |

I am NOT saying that Carcharodontosaurus is more advanced. Tyrannosaurus is NOT more advanced and also NOT better...You can't compare them like that... You are saying that I am a huge Tyrannosaurus hater, yet all you can say is popular sensationalistic bs...the irony is delicious... |

Really now? Carcharodontosaurus was mode for slicing, NOT crushing, it doesn't need a high bite force to do damage...why is it that you Tyrannosaurus fans think that damage is decided by bite force alone? |

Spinosaurus would never won a fight not even with carcha, giga or T-rex... his maxilar is large and nothing bulk... please do this by yourself push the 3rd finger and the first (spino bite) then push all your hand (T-rex bite) did you understand? spino wasn´t designed for fights (proved) his diet was fish and little preys (his arms and his claw was desinged to carch prey no to fight those arms doesn´t have the strenght to deal with the three carnosaurs I´ve mentioned.... |

Just stop, you're hurting yourself... It doesn't matter what you eat, they physical attributes matter. Spinosaurus is MUCH larger than the theropods you mentioned...and what makes you think the Spinosaurus would fight with it's arms or bite alone? It would use it's strength and size to win... Tyrannosaurus is also not a carnosaur...it's a coelurosaur |

This is like chicken vs turkey. T.rex is the chicken, and carchy is the turkey. Chickens run away from turkeys. So t.rexs run away from carchies. With that said carchy wins.

Carcha is not 3 times bigger than t. rex. |
