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 does NOT outweigh Carcharodontosaurus, it's the other way around! 9-tonne Tyrannosaurus? Are you high? That model is flawed, it assumes Tyrannosaurus was a fat sausage, a more realistic mass estimate for Tyrannosaurus would be about 6 tonnes... The "strongest leg muscles of any theropod" is complete bs, you just pulled that out of your butt, and it would take a LOT MORE than 1 kick to kill a Carcharodontosaurus, and the sharpest foot claws do NOT belong to Tyrannosaurus, in fact, they would belong to dromaeosaurids! Most of the Tyrannosaurus tooth is root, and tooth size means only a different feeding method! And the infectious bite thing was BASELESS speculation, not solid fact! Clash of the Dinosaurs and Jurassic Fight Club only presented it as solid fact, that's the only reason people believe that nonsense. CoTD and JFC are PURE TRASH!!! And even if it had an infectious bite, which is highly unlikely, due to it's high bite force rendering that unnecessary, there is NO REASON to believe that it would be exclusive to Tyrannosaurus. And Komodo Dragons kill with venom, not bacteria!!! |

The laser imaging doesn't make ALL Theropod look fat, what are you trying to prove ???. You try to prove all the latest methods are failed and we should stick to the old one. How many times do i need to tell you that only SUE appear to be fat, any other T rex specimens don't appear to be fat, Acrocanthosaurus, Allosaurus don't appear to be fat either |

He got the point, i believe T rex is heavier than Carcharodontosaurus, and so do many scientists BUT the whole things are bullshit, this guy has watched too much JFC

I´m trying to show you that it is biased to make one species or specimen fat to let it appeart heavier and not to apply the same to the others! Whether you use laser imaging or not, this will always hold true, and no matter what metods you use, if you give them too much bulk, especially compared to other weight estimations, you will always have biased results. |

EDIT: Read the comment by Lord of the allosaurs, it is far better than mine actually and he managed to be less insulting... you could indeed be palaeosaurus. 1. use max estimates for all animals, not just for your dear T. rex. I have to say this is the least dramatic inference you use, even tough I can hardly agree with it 2. it doesn´t bother me whether it is your favourite dino, but it does bother me that you are writing BS (no offence, but that´s the truth) 3. I want to see your 9t sausage-theropod kicking anything 4. I remember scientists writing t. rex had less pointed footclaws than carnosaurs, I´ll search for the source later 5. since when is tooth size important? 6. the bacteria thing was made up, and not even comodo dragons do actually use bacteria, they use venom, and an animal with a bite like T. rex would not have venom where on earth did you get your info from?

well, it IS from JFC, so jo wonder it reminds you of that. As far as i know no scientific source has actually ever theorized that BS, evne less now with eivdence for Comodo dragons killing with venom, not bacteria |

Hi Palaeosaurus!
Good for you. My favourite is Carcharodontosaurus. Does that automatically give it a massive advantage over Tyrannosaurus? Not at all.
Errr....no. Carcharodontosaurus is most likely the heavier of the two.
This is biased. You are using the highest feasible weight estimates for Tyrannosaurus and some of the lower ones for Carcharodontosaurus. Fine, if Tyrannosaurus is 9 tonnes then Carcharodontosaurus is 15 tonnes. IMO both statistics are quite ridiculous; more likely they would both weigh ~7-8 tonnes. Basically, if you want to be accurate and fair to both contenders then don't use the highest weight estimates for one and not for the other.
Umm...okay? Tyrannosaurus is one of the fastest runners of all large theropods; there is no denying that. But as I have stated numerous times, running speed =/= agility. Agility makes more of a difference in a fight than running speed, and with its slender build, Carcharodontosaurus > Tyrannosaurus in terms of agility. I remember reading somewhere that it would take close to 2 seconds for a Tyrannosaurus to turn 90 degrees; almost painfully slow, in relative terms. That's the thing about an allosaurid build; it gives you high agility, compared to more bulky theropods like tyrannosaurids.
And they're doing a lot of good positioned underneath the horizontally alligned body. Theropods could kick, probably, but not to the degree that an animal with a vertically alligned body (for example, a human, other primate etc.) could.
Uh, that is FAR overrating the power of a Tyrannosaurus kick. Assuming it is flexible enough to reach the Carcharodontosaurus' body (and the evidence suggests it isn't), the kick would A) Cause a bit of damage, but not a lot. B) Cause the tyrannosaur to topple over immediately. So in a nutshell, a Tyrannosaurus kicking a Carcharodontosaurus = Carcharodontosaurus victory.
...And only about half of that comes out of the gum. Counting the root, human teeth can be two inches long. But it's clear that functionally, they're not.
*Heavy sigh* Firstly, Jurassic Fight Club is the only source that has ever suggested that Tyrannosaurus has a septic bite. In fact, Phil Currie and Gregory S. Paul have BOTH written/stated that they do not believe Tyrannosaurus had a septic bite. I think I'll take their word over an old paleontologist wannabe who calls himself "Dinosaur George". Secondly, komodo dragons kill their prey with venom and not with bacteria. And thirdly, if Tyrannosaurus had a septic bite, then so would every other theropod with serrated teeth, including Carcharodontosaurus.
IMO this fight is so close that I wouldn't be willing to put my money on either, but if I HAD to, I'd vote for Carcharodontosaurus. Edited by Shaochilong, Nov 12 2012, 04:33 AM.

Oh god you little kid, do not tell me you are palaeosaurus
Well good for you, it really shows how biased you are. My favorite dinosaur is Allosaurus, but does that mean I think it can kill anything? Ridiculous.
No, it does not, Carcharo is actually likely the heavier one.
Wut u bin smokin?!?!?!?!?!? The theropods, that have the sharpest foot claws, are the dromaeosaurs
No, it cannot. Carcharodontosaurus would be too sturdy to be killed by a kick, you are severely overrating T.rex's strength.
Teeth size is irrelevant, not to mention half of that is inside the gums....... so it doesn't help it.
Are you retarded? No i mean seriously? JURASSIC FIGHT CLUB WAS FREAKING WRONG!!!!!! There is NO true evidence to prove the stupid theory that T.rex had an infectious bite. And Komodo Dragons kill their prey with VENOM, not bacteria!!!!
Again, good for you. Carcharodontosaurus is the real winner here. Edited by Carcharadon, Nov 12 2012, 06:05 AM.
