The longgest meat-eating dinosaur yet discovered is Giganotosaurus, a 44-46 ft (13.5-14.3 m) long behemoth, who weighed about 8 tons and stood 12 feet tall (at the hips). It walked on two legs, had a brain the size of a banana, and had enormous jaws with 8-inch long serrated 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, toward the end of the Mesozoic Era, the "Age of Reptiles".

Giga-noto-saurus means "giant southern reptile". Its fossil was unearthed in Argentina in 1994. 70 percent of the skeleton has been found. Near the Giganotosaurus, fossils were found of 75-foot-long plant eaters, presumably victims of this Giganotosaurus.
