It is now being claimed this is the biggest creature ever to 'walk' the earth, even larger than the blue whale. In the marine environment, and unable to walk, the blue whales can grow up to 33m in length. We are told Argentinosaurus was 36.5m in length, from its nose to the tip of its tail. It weighed in at 100 tons. Argentinosaurus is one of a group of dinosaurs known as Titanosaurus. They had very long necks and super long tails.
