In southern Argentina, scientists discovered the remains of seven adult dinosaurs that lived 95 million years ago. The huge beasts belong to a family known as the titanosaurs. They may be the biggest dinosaurs to have ever roamed Earth.
The newfound dinosaur would have towered over carnivores like beasts in the Tyrannotitan genus, as well as giraffes and humans, as this diagram shows.
Heavy Duty Job
Using jackhammers, shovels and even bulldozers, researchers from the Museum of Paleontology Egidio Feruglio in Argentina's Patagonia region removed the fossils from a site in the center of the Chubut province, about 160 (260 kilometers) from the city of Trelew.
