Giganotosaurus is the longest meat-eating dinosaur yet discovered. This enormous theropod dinosaur was slightly taller than T. rex. It lived during the mid-Cretaceous period, roughly 100 to 95 million years ago, in what is now South America.

Anatomy: Giganotosaurus was 44-46 ft (13.5-14.3 m) long, stood about 13 feet (3.9 m) tall (at the hips), and weighed about 8 tons. 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.

Fossils and Name: Giga-noto-saurus means "giant southern reptile". Its fossil was unearthed in the Patagonia region of Argentina (in southern 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. Giganotosaurus was named by Rodolfo Coria and Salgado in 1995.
