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. ![]() _________________________________________________________________________________

But turkeys are like 3 times as big as a chicken. Your analogy makes no sense. |

There's no chicken or turkey in that video, and the T. rex wins in that video. |

The comment is false. T. rex is not 12m maximum, Sue is already over 12m. Carcha is not 16m either as far as we know. It's probably somewhere between 12-14m. I have seen chickens and turkeys kept in the same pen, they aren't running from the turkey... And whoever made that comment made a terrible analogy, and you agree with him?

Exactly, was that that difficult to see? Someone comparing carcharodontosaurus to a turkey(!!!) and T. rex to a chicken(!!!!!) MUST be joking! I would say the carchy neotype basing on known dimensions of the holotype and its respective size was almost certainly more than 12,5m long, imo probably between 13 and 14m. The holotypes skull seems Acrocanthosaurus sized (~11,4-11,9m), and its femur is even longer (this taxon appears to be relatively short skulled but long legged when comapred to giganotosaurines and Acrocanthosaurus). Estimates lower than that are really unreasonable, especially those sad people on youtube who ahve the believe that it was 11-12m... PS: Sorry, felt like making some exclamation marks, I might have been infected by dinosaur. Will a virus scanner help or do I need a psychologist? PPS: Just in case you where wondering, that was meant to be understood in a humorous way PPPS: making some jokes feels good! PPPPS: shit, another exclamation mark! PPPPPS oh no... |

I completely forgot to say this, when i made the comparison of carchy/turkey vs t.rex/chicken, i was just trying to compare the behavior of what would happen, not the size at all. But yea i was just joking. |

Damn it, I haven't seen that there's a page 34. He wasn't faster, I didn't look properly.

T-rex should win, but it will suffer cuts and bites in the end. The carcharodontosaur will have chances of winning due to it's slicing bite. |
