I believe the order would be (from largest to smallest): Giganotosaurus, Brontosaurus, Tyrannosaurus Rex. Although, the T-Rex is the largest meat eating dinosaur.
As you probably know, the time of the dinosaurs is divided into three main periods: The Triassic, the Jurassic, and the Cretaceous. Thus there was NO "king of dinosaurs". They all lived in different periods, though most people seem to think it was the Tyrannosaurus Rex, as it was the largest dinosaur. However, now, Giganotosaurus is proven to be much larger than Tyrannosaurus.
No. T.Rex is actually a bit smaller than Giganotosaurus. Giganotosaurus is believed to be the biggest, deadliest carnivore that has ever lived on Earth. >:D
Yes, Giganotosaurus was a huge carnivorous dinosaur that was slightly larger than T-Rex. Giganotosaurus lived in South America during the early cretaceous and probably hunted large herbivores like Argentinosaurus.
Giganotosaurus (pronounced "JYE-ga-NO-toe-SORE-us"[1])It is one of the largest known terrestrial carnivores, slightly larger than Tyrannosaurus, but smaller than Spinosaurus. Its fossils have been found in Argentina.Source: http://en.wikipedia.org/wiki/Giganotosaurus
Carcharodontosaurus is a meat eater even larger than T-Rex, but smaller than Giganotosaurus. It is about 17 ft high, 43 ft long, and weighs about 7 1/2 tons. Their teeth are almost 7 inches long.
It was previously thought that the Tyrannosaurus Rex was the king of the dinosaurs. However, recent evidence has proved this was wrong. The king of the dinosaurs was actually the Spinosaurus. Which was much larger, stronger, faster and far superior than the T-Rex.
i'd say tyrannosaurus because it had a much stronger bite force than giganotosaurus did. though it's possible for giganotosaurus to beat t-rex. but the might not have fought because t-rex lived in north America and g-rex(giganotosaurus) lived in south America. g-rex was a pack hunter. so 1 t-rex wouldn't stand a chance against a pack of g-rexes.
Tyrannosaurus rex was 40 feet long and weighed 5 tons. Stegosaurus was 30 feet long and weighed 5 tons. So both dinosaurs had about the same weight, but Tyrannosaurus rex was longer, and also taller because it walked on two feet.
Giganotosaurus spinosaurus carcharodontosaurus and allosaurus.
It depends on what species of dinosaur it is. Dinosaurs like Utahraptor and dromeosaurus probably hunted in packs and preyed on herbivores much larger than them like iguanadon.
Because of the black coons.
Tyrannosaurus rex, even if spino and giga are slightly larger they were never ever as highly evolved as t-rex. T-rex had the strongest jaws/biteforce of anyother carnivores. The largest brain of any large meateater, perfect eyesight{contridicting what jack horner the palentology consultant from Jurassic park says}andt, he strongest/built body which makes up for his lack in size compared to giganotosaurus or spinosaurus, by the way t-rex would slaughter either of them if they ever came face to face.
