Just How Big Was the Largest Dinosaur? Bigger Than You Think.

Reaching nearly half a football field in length and starting from an egg smaller than a human baby, this dinosaur was king of herbivores.

The largest dinosaur that ever lived has been revised many times. Some paleontologists thought it was the Brontosaurus, way back in the day. Since then, the coveted crown of the world’s largest dinosaur has shifted a few times. Regardless, the type of dinosaur that must have been the largest animal to ever walk the face of the earth has never been in question. It was a type of sauropod.
