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. ![]() _________________________________________________________________________________

Some people wrote the arms are only SLIGHTLY longer than those of T-rex. |

They would hardly have such huge claws if they were useless like the ones of T rex. |

CryrolophoFan2012 once stated this in context of Giga, he said Carcharodontosarids had very short arms compared to those of Allo. |

That´s true. Anyway, Carcharodontosaurus had huge claws, that´s not just a guess made using allosaurus as a reference. There have been enourmous ones found in northern africa. |

OK, then maybe he is a T rex fanboy, but an allosaurû fanboy even more so. Strange to see something like that. |

Are actually debating on the views of others(wo are prob not even members) on this topic? IMHO that would be extremily insignificant to this thread. |

Can anyone give its reasoning for believing that Carcharodontosaurus was 13-15m? before anyone says C. iguidensis with its 1.75m skull, sorry but the size of the skull was completely made up by the press, the paper where it was actually described did so in it this way "and grew to the same large body size as C. saharicus"

Which wans´t specified any further. however the estiamtes for Carch that I know actually are all between 12 and 14m. 15m seems exagerated. if the skull wasn´t 1,75m long how long was it? 1,75 is the only figure I have ever read. |

Slightly toward T.rex because of the most devastative bite and more powerful legs, IMO. |

I don't think the claws were that long. If it had 5 ' arm, that would mean claws over 1/5 of the arm's length! I think in this fight the claws would be more useful to hook its opponent and deliver a more powerful bite, rather than for inflicting serious wounds. If Carcharo could open its mouth more widely, that could be an important factor. Do anybody have some source that states how much these dinos could open their jaws? The teeth of T-rex would be better however. Thye could pierce deep through hide and bone, but still they would be almost as useful as Carcharo's teeth for tearing flesh, through theirs sheer size and curved shape. If Carcharo's highest weight estimate mentioned in the OP is correct, though, I would favor it. |
