Answer by  ambersfrog (157)

The Argentinosaurus was the heaviest dinosaur. Scientists think that they could weigh up to 220,000 pounds. It was a herbivore and looks like it was closely related to the more commonly known brontosaurus. To get an idea of the size of this creature you can compare it to a blue whale which can weigh up to 230,000 pounds.
