Giganotosaurus is 10-15 percent more massive and longer than Tyrannosaurus rex, which for a long time was record holder.Giganotosaurus was an incredible animal, around 13 meters in length.And the head was huge, around one meter and 80 centimeters.Giganotosaurus had a skull the length of a man.But this giant predator had one more thing to reveal.When the team dated the bones, they found Giganotosaurus lived in the Cretaceous, the time of the giant long-neck Argentinosaurus.And the two dinosaurs were found only 80 kilometers apart.For the first time anywhere in the world,scientists had discovered mega-carnivores and huge plant-eaters living during the same time period and in the same place.This is a peculiar ecological relationship that we found in Patagonia.Big preys and big predators.If we look at South America in the age of Giganotosaurus,the main potential prey for this immense meat-eater is an even more immense plant-eater, the giant Argentinosaurus.Could it be true that in Patagonia something unique happened?That the largest plant-eater ever came face-to-face with the largest known meat-eater in an extraordinary clash of the titans?
