Who would win Mapusaurus or Giganotosaurus?

They might seem like they lived at the same time, but, the truth is Giganotosaurus carolinii lived during the early Aptian stage ( 97 million years ago ), and it seemed Mapusaurus roseae was a direct descendant of Giganotosaurus, evolving two million years later ( one million year ago, Giga went extinct, meaning the two animals never actually met ). As well as that, it, not Giganotosaurus, is the hunter of the extremely large Argentinosaurus huinculensis, that lived at the exact same time and formation ( the Huincul formation), while Giganotosaurus lived in the Candeleros formation, hunting the not as big Andesaurus delgadoi and Limaysaurus tessonei. Now, in matters of size and power, that Giga, yet it is primitive, slow, and probably dumb. But Mapusaurus evolved from it, so it is smaller, sleeker, lighter, faster, probably smarter, and, most of all, it is a pack hunter, allowing it to take down the largest animal to ever walk the earth ( Argentinosaurus). It is more advanced, because when an animal evolves, it is usually better and more advanced than its primitive ancestor.

Now I admit, I cannot answer this question because each animal has its own strengths and weaknesses. But this will key phrases might help you get the answer.

1) It does not matter if you are so strong;if you are outnumbered, you lose

2) Your enemy may be strong and big, but he may be slow. If you are fast, you can run around him and still stay alive. And, you can score pain and get away.

3) Strength has limits. Even strength has to bow to wisdom sometimes.
