Although Argentinosaurus is twice as long as the blue whale, it only weighs half as much.

that's wrong dude, Argentinosaurus was about 30-35 m long and weight 80-100 tonns, the blue whale is also around 30 m some have reach more and they weigh about 170-190 tonns so Argentinosaurus is NOT twice as long

Actually both of you are wrong. Argentinosaurus weighs around 73 tons based on recent estimates, while 190 tons is nowhere near average; closer to 120-150 tons. Also Argentinosaurus is not the largest dinosaur; that title probably goes to Amphicoelias fragillimus at 122.4 tons. Even ignoring Amphicoelias, Argentinosaurus still probably does not weigh as much as the 80-85 ton Puertasaurus, though that is a matter of debate.
