Giganotosaurus is one of the biggest carnivorous dinosaurs yet discovered. It had a length of 40-43 ft (12.2-13 m). The Giganotosaurus weighed between 6.5 and 13.3 tons and stood towering above many other dinosaurs. It walked on two legs and had a brain the shape and size of a banana. It had enormous jaws with 8-inch long teeth in a 6-foot (1.8 m) long skull. Giganotosaurus was a theropod from the mid-Cretaceous, living about 100-95 million years ago.
It is a dinosaur that means "giant southern lizard". Its fossil was found in Argentina in 1994. 70 percent of the skeleton has been found. Near the Giganotosaurus, fossils were found of 100-foot-long plant eaters. It is thought that these were victims of the Giganotosaurus. Giganotosaurus was probably supported as the second largest carnivorous dinosaur of all time it weighed between 6.5 and 13.3 tons and was 11.5 feet [3.5m ] feet high at the hip. We do know that giganotosaurus was larger than tyrannosaurus in weight, length and height. It may have preyed on the largest sauropods such as argentinosaurus, as it did in packs in the walking with dinosaurs special, chased by dinosaurs, land of giants, and dinosaurs giants of patagonia. Scientists are looking for more giganotosaurus fossils.
