Argentinean scientists have discovered gigantic neck, back, and tail bones from one of the biggest dinosaurs to ever roam the Earth. Puertasaurus reuili, seen here in an artist's conception, is estimated to have been 115 to 131 feet (35 to 40 meters) long and weighed between 88 and 110 tons (80 and 100 metric tons).

The new species, which lived about 70 million years ago, is one of the titanosaurs, a group of plant-eating sauropod dinosaurs that walked on four feet and are known for their long necks and tails.
