In 2007, the paleontologists François Therrien and Donald M. Henderson found that Giganotosaurus would have approached 13 m (43 ft) in length and 13.8 t (15.2 short tons) in weight, while Carcharodontosaurus would have approached 13.3 m (44 ft) in length and 15.1 t (16.6 short tons) in weight (surpassing Tyrannosaurus), and estimated the Giganotosaurus holotype skull to have been 1.56 m (5 ft ...

- The Name Giganotosaurus Has Nothing to Do With "Gigantic" Giganotosaurus (pronounced GEE-gah-NO-toe-SORE-us) is Greek for "giant southern lizard," not "gigantic lizard," as it's often mistranslated (and mispronounced by people unfamiliar with classical roots, as "giganotosaurus").
- Giganotosaurus Was Bigger Than Tyrannosaurus Rex. Part of what has made Giganotosaurus so famous, so quickly, is the fact that it slightly outweighed Tyrannosaurus Rex: full-grown adults may have tipped the scales at about 10 tons, compared to a little over nine tons for a female T. Rex (which outweighed the male of the species).
- Giganotosaurus May Have Preyed on Argentinosaurus. Direct proof is lacking, but the discovery of the bones of the giant titanosaur dinosaur Argentinosaurus in the proximity of those of Giganotosaurus at least hints at an ongoing predator-prey relationship.
- Giganotosaurus Was the Largest Meat-Eating Dinosaur of South America. Although it wasn't the largest theropod of the Mesozoic Era—that honor, as stated above, belongs to the African Spinosaurus—Giganotosaurus is secure in its crown as the largest meat-eating dinosaur of Cretaceous South America.
Mar 17, 2016 · What did Giganotosaurus eat? Scientists believe that Giganotosaurus survived mostly on large herbivore dinosaurs. Because of its size, it did not have any natural predators.
Giganotosaurus was a member of a family of large carnivorous dinosaurs that also included Mapusaurus and Carcharodontosaurus. Giganotosaurus is thought to have reached a length of 12−13 meters (about 40−43 feet), a height of 7 meters (about 23 feet), and a weight of 7,000–8,000 kg (about 15,400–17,600 pounds).

- Giganotosaurus Was Speedier Than T. rex. There has been a lot of debate lately about how fast Tyrannosaurus rex could run; some experts insist this supposedly fearsome dinosaur could only attain a top speed of a relatively pokey 10 miles per hour.
Size and Comparisons. Giganotosaurus is estimated to have reached lengths of 12 to 13 meters (39 to 43 feet) and to have weighed between 4.2 and 13.8 metric tons. When compared to its contemporaries, it was one of the largest known carnivorous dinosaurs, rivaled by the likes of Tyrannosaurus rex and Spinosaurus.
