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. ![]() _________________________________________________________________________________

Tyrannosaurus Rex due to more powerful bite, and more robust body. Not to mention it's the most advanced Theropod. |

If Planet Dinosaur is anything to go by, it would appear that shark-tooth has a weaker bite, and would have preferred to simply let prey bleed to death rather than kill it outright. The injuries it could inflict on T.Rex (which was itself accustomed to being stabbed by ceratopsians and bitten by conspecifics) wouldn't be anything it can't handle. |

The Tyrannosaur would win from as you said bigger jaws stronger bite andmore robust.The tyrannosaurus would also win from being more advanced, though Carcharodontosaurus is bigger. |

Depends on the size we give Carch. If we choose 13 Meters I would say 50/50. If we believe in 15 Meter I think Carch would win. I more believe in 14 Meters for Carch, it seems more likely. I'm not sure who would win there. |

While carcharodontosaurus was 5 feet longer than t-rex, the tyrannosaurus was stronger and more heavily-built. The tyrannosaurus had a thicker body build and a much stronger bite. If the tyrannosaurus could land a good, bone-crushing bite on the carcharodontosaurus's neck, it would be all over. It is basically rail-road spikes (t-rex teeth) against steak knives (carcharodontosaurus teeth). The rail-road spikes are more for direct force and creating deep puncture wounds, while the steak knives are better for slicing open skin and creating blood loss. |

Agreed. Also I think Rex was slightly more intelligent, even though it won't help much. |

It's accurate, but you forgot that Carcharodontosaurus had stronger arms as extra weapon. |

^Stronger but still small. If it's gonna use it, it's gonna have to come within like 1 meter of the T.rex. |

Of course still small, but they can be used for grabbing the opponent, if it jumps from the side to rex. |

Carcharodontosaurus also had larger claws. So that could be a useful weapon too. Edited by Godzillasaurus, Feb 7 2013, 07:38 AM.
