Giganotosaurus 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% complete.
Giganotosaurus was one of the largest terrestrial meat eating carnivores, even bigger than the Tyrannosauruses. They were bigger than even Tyrannotitan and Carcharodontosaurus. This genus of Carcharodontosauridae is the most powerful Carcharodontosaur.
It hunted the Argentinosauruses, the biggest dinosaurs of all. Well, the life of Giganotosaurus wasn’t so easy because it’s known for eating Giganotosaurus siblings! And the Argentinosauruses, which just walk on them and thus, crushing them! They were even faster than the Tyrannosaurus rex because it was more lightly build. It’s specimen was MUCPv-95, that was a fully grown, was even bigger than the female Tyrannosaurus rex, Sue! But the skeleton was not in one piece.
To summurize Giga was the ‘Usain bolt’ type MegaTherapod, using its speed to overpower prey.
