Giganotosaurus
Giganotosaurus is a large theropod dinosaur. It lived during the Upper Cretaceous, about 99 - 97 million years ago in what is now Argentina. 70 percent of the skeleton has been found. Giganotosaurus was probably the second largest carnivorous dinosaur of all time. Another large carnivore, Mapusaurus, also lived in the same territory. They were both relatives of the North African Carcharodontosaurus.

The largest specimen is 14 m (46 ft) long,[1] and 4 m (13 ft) tall at the hip. Its weight is estimated as 13 t (29,000 lb).[2][3]
Titanosaur fossils belonging to Andesaurus and Limaysaurus have been found near the remains of Giganotosaurus. The huge titanosaur Argentinosaurus also lived in the area. Probably, the titanosaurs were the main prey of the large theropods.
