the argentinosaurus bigger than blue whale?

Yes, the Argentinosaurus was bigger than the blue whale. While estimates of the Argentinosaurus's size vary, it is believed to have been anywhere from 98 to 130 feet long and weighed between 80 to 100 tons. The blue whale, on the other hand, is the largest known animal on Earth and can grow up to 100 feet long and weigh up to 190 tons. However, the Argentinosaurus was likely taller than the blue whale and had a longer tail, meaning that it would have taken up more space and may have displaced more water. Therefore, it can be said that the Argentinosaurus was bigger than the blue whale in terms of size and displacement, but not in terms of mass.
