T-rex vs Gigantosaurus who would win?

Giganotosaurus: Size, speed, agility, functioning arms, much longer skull, adapted to take on big prey, good eyesight, good smell, great hearing Tyrannosaurus: Greater bite force, binocular vision, slight intelligence advantage(t Rex has a small alligator-like cerebrum, Giganotosaurus had a relatively big but still small cerebrum, so both were in the kitten to alligator range) great smell, average hearing Giga has more advantages.

Giganotosaurus- Steak knife teeth, speed, arms, decent vision, good smell, good hearing, can take on large prey(Sauropods), pack hunter. End Result... [img]http://i50.tinypic.com/5b7fj9.jpg[/img]

Giganotosaurus, powerful l bite (that's 2-3 cars coming from the bite. Everyone compares bites to T. rex. T. rex is just a super power bite, not a regular bite, so strong bite.) long arms. Dumb as a rock. Fast, agile, heavy (once again, not compared to T. rex) long, tall. T. rex, supercharged bite. Not very fast. Very smart. Small, yet strong arms. Heavy. Septic bite. I'd say most of the time, its a draw. They are both huge and powerful. T. rex might win a bit more times, but Giganotosaurus would infict more injuries. Leading rex to bleed to death.

T-Rex: Binocular vision, most powerful bite out of all carnivorous dinosaurs, banana sized sharp teeth used for crushing bone, powerful bone structure used for taking hard hits, infectious bite, smart as a house cat. Giganotosaurus: powerful bite strong enough to inflict damage but not nessacarilly immediate death, slightly slender bone structure, fast runner, razor sharp teeth, slightly larger than t-rex, not very smart, agile. Giganotosaurus would put up a pretty good fight but in the end I think The King would win nonetheless.

giganotosaurus:the super bite force is not much thing if the giga too fast for the t.rex(i mean that the giga could run 50km/h)and with its meat slasher teeth it dont need to get as close to the t.rex.it just need to bite it to make an enogh deep,bleeding wound and after that the giga just need to wait

It would take more than a single bite to take down a fully grown Tyrannosaurus rex. T-rex is a lot more powerfully built, smarter, has better vision, ect. Giga is dangerous and would put up a fight, but Tyrannosaurus would probably be the victor 60-65 percent of the time. Giganotosaurus would win about 35-40 percent of the time.

The giga brain size from a reconstructed skull,and if 9 tonns hit a t.rex with its top speed,powerfully built or not the t.rex fell on the ground but i say again 50/50% i think that the winner is who surprise the other, And if the giga do like this it could easily defeat the rex:the giga hit the rex wit its top speed,the rex fell on the ground,the giga bite its neck,the rex try to escape but when its pull him neck from the gigas mouth its teeth slash its throat, after the t.rex try to escape but the giga again bite its neck and do the wound more deeper. and what animal can survive when cut its throat?this is why i say that the winner is who surprise the other.
