Giganotosaurus carolinii or Giant Southern Lizard is a genus of theropod dinosaur that lived in what is now Argentina, during the early Cenomanian age of the Late Cretaceous period, approximately 98 to 97 million years ago.

The holotype specimen was discovered in the Candeleros Formation of Patagonia in 1993, and is almost 70 percent complete. The animal was named Giganotosaurus carolinii in 1995; the genus name translates as “giant southern lizard” and the specific name honours the discoverer, Rubén D. Carolini.

A dentary bone, a tooth and some tracks, discovered before the holotype, were later assigned to this animal.

Giganotosaurus carolinii is thought to have been one of the largest theropod dinosaurs, but the incompleteness of its remains have made it difficult to estimate its size reliably. It is therefore impossible to determine with certainty whether it was larger than Tyrannosaurus, for example, which has been considered the largest theropod historically.

Different size estimates have been reached by several researchers, based on various methods, and depending on how the missing parts of the skeleton have been reconstructed.

Length estimates for the Giganotosaurus carolinii or Giant Southern Lizard specimen have varied between 39 and 43 ft., with a skull between 5.0 and 5.9 ft. long, a femur (thigh bone) between 4.48 and 4.69 ft. long, and a weight between 4.6 and 15.2 short tons. Fusion of sutures (joints) in the brain case indicates the holotype specimen was a mature individual.

The Giganotosaurus carolinii dentary of the lower jaw expanded in height towards the front, where it was also flattened, and it had a downwards projection at the tip.

Giganotosaurus carolinii is thought to have been the apex predator of its ecosystem, and it may have fed on juvenile sauropod dinosaurs.
