The Giganotosaurus looks a lot like the Tyrannosaurus Rex. They were both fearsome hunters, had very short arms, moved on two legs, and had a large skull. But the Giganotosaurus lived much earlier, in North America, the Tyrannosaurus Rex, in South America.
Fun fact: The Giganotosaurus was 12-13 meters long, but its brain was barely 30 cm.
