Which dinosaur grew upto 40 meters and weighs upto 100 tons?

Argentinosaurus grew up to 35 meters long and weighed up to 110 tons. The Amphicoelius, a very poorly known dinosaur, mayhave been 40 to 60 meters long, and could have weighed up to 135 tons. However, the only fossils of Amphicoelius, a femur and some vertebrae, were lost. Without more bones, it is impossible to be certain of its size, weight, or proportions.
