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.
Based on analysis of the vertebrae and comparison with smaller, better-known titanosaurs, the paleontologist believes the new find was 115 to 131 feet (35 to 40 meters) long and weighed between 88 and 110 tons (80 and 100 metric tons).
Its chest alone was nearly 16 feet (5 meters) in diameter, about the size of an entire modern-day elephant.
