Argentinosaurus
The name itself is a dead giveaway about the place where its remains were discovered, Argentina. Archaeologists peg the size of this scary looking giant at 130 feet long and weigh about 70 tons. The statistics easily puts it among the biggest dinosaurs that ever walked the earth. Although it is as scary as it may look, this one eats plants and would not sow fear on other animals. It lived in the latter stages of the Cretaceous era.
