Giganotosaurus

The giant southern lizard that rivaled T. rex in size/Dinosaurs & Extinct Animals

Giganotosaurus carolinii lived about 99 to 97 million years ago during the Late Cretaceous in what is now Argentina. At roughly 12 to 13 meters long and up to 8 tonnes, it was one of the largest known terrestrial carnivores. Its skull alone measured about 1.6 meters, slightly longer than that of Tyrannosaurus rex, though its brain was considerably smaller. Giganotosaurus likely hunted large sauropods like Argentinosaurus.
