The bones of seven huge dinosaurs that each weighed more than a dozen elephants and had femurs bigger than a human adult have been discovered in Argentina, scientists announced.
The plant-eating beasts plodded across South America 95 million years ago, during the Mesozoic Era, and they may represent a new species. The creatures may even be the biggest dinosaurs known, outshining their long-tailed, long-necked titanosaur cousins like Argentinosaurus, said the paleontologists who excavated the bones.
