World's Largest Dinosaurs

They were BIG. Really BIG.

Picture four city buses, parked bumper to bumper. Now, imagine that instead of four chassis and several sets of wheels, you’re looking at the body and tail of a single enormous dinosaur, supported by four sturdy legs as wide and as tall as trees! That’s about the size of some of The World’s Largest Dinosaurs — the super-sized sauropods that thrived on Earth for approximately 140 million years.
