Heaviest Dinosaur Discovered

发现最大恐龙化石

Argentinean palaeontologists believe they have discovered dinosaur bones from the largest creature ever on earth. They believe the bones are from an unknown species of titanosaur, a long-necked herbivore that walked on earth about 95 million years ago. The scientists estimate that the creature weighed about the size of 14 elephants. To estimate the body mass, they measured the circumference of the humerus and the femur. These are the bones that support the body weight.
