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. ![]() _________________________________________________________________________________

Nevermind. I now change my vote to Carcharodontosaurus Larger, stronger, and has a more devastating bite and would utterly destroy t.rex |

According to Sakamoto, the Rex probably had a more powerful bite force. But if you mean bite force and teeth shape overall, yeah. |

^When i said more devastating bite, i mean a deadlier bite. Slicing is deadlier than crushing.

Hmm, that is subjective. Crushing bite mangles whatever section it comes down on.A slicing bite is only effective in the most vulnerable of areas |

My two cents, T.rex has the highest chances to kill Carcharodontosaurus first by breaking a vital bone structure, like the neck, which would be the most likely target in such a battle. But just like for Giganotosaurus, T.rex has only few chances to be killed in first however it could die shortly after the fight of massive exsanguinations, depending the body parts bitten. However, Giganotosaurus, with its larger skull and jaws and slightly larger body, is thougher contender to T.rex. Carcharodontosaurids don't have the famous bone-crushing dentition of T.rex but they had gruesome slicing bites. Actually Giganotosaurus, the largest of them all known at now, packed possibly the most horrific flesh-slicing scissors that ever existed on Earth. Theses guys have not to be underestimated.

I disagree. Some people don't see eye to eye on me with this statement but I doubt two multi ton similar sized theropods could bite anywhere else besides the jaw area in a non ambush scenario, simply because their would have to be a huge gap in agility for one theropod to be able to oumanvuer its opponent. |

I don't say it would be easy for any of these animals to bite the other, but the fight wouldn't keep like this indefinitely, at one moment, one carnivore will bite the other. To my knowledge, the fossils records indicate the neck and head are commonly targetted area among theropods in presumable fights. |

Well, if you take the maximum for Carcharodontosaurus (13m) you have to take the maximum for Tyrannosaurus (MOR 008=13m). |
