Giganotosaurus is the biggest meat-eating dinosaur ever! It was found in South America, Argentina. It lived in the Late Certaceous. It was Bigger than T-Rex and Carcharodontosaurus! It was 42 feet ( 12.5 m). It hunted in packs because it attacked sauropads like Argentinosaurus. It's skull was long as a human! It was one big dino!
Now if you thought that Giganotosaurus was big ... THINK AGAIN! Argentinosaurus was the biggest dinosaur ever! It was 123 feet (37.5m). It is a sauropod ( it is in the picture). Early Cretaceous. Each back bone weighs 2 tons. it was a plant -eater. It was named after Argentina.
Now imagine the 2 dinosaurs we were talking about fighting. Wouldn't that be cool! Giganotosaurus slicing teeht. Argentinosaurus had size. 2 BIG dinosaurs fight. one big questin remains .. who would win!? Who knows? Maybe Giganotosaurus, or Argantinosaurus. Who knows?
