Giganotosaurus carolinii. Based on fossil found in Argentina. Cretaceous, 112 - 89 million years ago.

Giganotosaurus belongs to the same group as the North American Allosaurus and has three fingers on each hand, typical of allosaurs. It displaced Tyrannosaurus rex as the largest meat-eating dinosaur when its discovery was announced in 1995. Giganotosaurus possibly lived in family groups, as at least four of these dinosaurs of varying ages were found in a fossil bone-bed in Argentina.
