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.

Fact is we know the most about Tyrannosaurus Rex since we have the most specimens and it's being studied the most, so if anything its data is the most reliable and scientific compared to carchy or spino. I can't believe people are calling the results biased purely because they are from newspaper or whatever.
Anyway the difference in length is roughly 1m more or less, my comparison has shown Sue at 12.8m is much bulkier and taller than a 13.8m Carchy, therefore it's most likely that T.rex would weigh more all said and done.

Now we are coming closer because now it is not about whether to use the laser scan on T. rex and not on Carch but about whether Carcharodontosaurus is actually heavier than T. rex. Boney, we are achieving progress in this debate!

Well, there isn't much I could say until somebody scans a Carchy so let's move on. So, I guess we can all agree that T.rex is the bulkier and more powerfully built animal according to the skeletal drawings then. In a fight T.Rex can end it fast with a nicely placed bone crushing bite to the neck all thanks to its true binocular vision and jaws of 6tons of pressure armed with banana sized teeth. In a long dragged out fight, T.Rex can still out-muscle carchy by having a much stronger skull for ramming, bigger neck (almost twice as thick) and barrel like chest for wrestling, and of course being potentially heavier. But in the end it would probably bleed to death shortly after due to numerous bites from the shark toothed beast, no one wants to be at the receiving end of those sharp teeth either.

LOL I love how certain people deduct the size of chimaeric taxon on the base of the lenght of a skull reconstructed(probably wrong as time will show) from literally scraps.
I think a better method to test the bones taste at full moon while dancing in a circle clad in a ballerina costume.
Or lets roll a dice.

In the fight situation I slightly favour Carcharodontosaurus, because of potentially larger size, arms that make up for being more slender and for having slicing dentition and the skull lenght and gape+sharp sawlike dentition like a squaliform. Speed and agility remain to be studied more closely. I´m inclined to say T. rex would likely have been faster due to longer metatarsals and tibiae (but not by as much as some would like to believe as carchy is less bulky in exchange). I really don´t know about the agility part, I remember 7Alx wrote something about the knee joints.

@ theropod, I think you mean Squalimorph, Squaliforma is a species of armoured catfish. And even the former do not always have saw-like dentition(actually, I have a hard time thinking of one).

Sorry, my mistake, I actually confused some Elasmobranch taxa there (it got a bit complicated as it is unknown whether sharks are still monophyletic...). anyway, I meant Sharks or better, what you would think of as a shark.

I thought this would look cool, still T.Rex takes this with brutal strength ad bite force.

Also still waiting on your 13.5m Carchy.
Carcharodontosaurus iguidensis was probably 13-14 metres long

I took the median estimate, 13.5 meters...
That is an old newspaper, i still see the 1,75m over-exaggerated Carchar skull in that newspaper.

And if you like to use newspaper as a scientific proof, then T rex would be 14-15m long rolleyes

I favor Tyrannosaurus in this fight. The T-rex weighs ~6-7 tons vs a ~6-7 ton Carcharo. The durability and bite of the rex would let it come out on top.

There is almost no way a lightly built avian theropod the size of T-rex weighed 9 or more tons...

^the t.rex's BITE would let it come on top? not really, bite force don't really matter.....

Carcharo basically a shark like bite, which slices, and it is more painful due to blood loss

Blood loss is actually painless. Shark victims can tell you that. Tho the land shark has a higher chance of cutting through important ligaments and muscles etc.

Coming from a guy who probably never got his arms sliced or crushed.

Their bites really cancel out.

Most people seem to forget that T. rex bite is fully capable of slicing, in addition to the cutting of its premaxilliary teeth.
