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.
阿根廷古生物学家认为他们发现了世界上最大的恐龙化石。他们相信这些化石属于“无畏龙”，它是一种生活在大约9500年前的长颈食草类恐龙。科学家预计，这种恐龙大约有14个大象重。为了对它的身形进行估算，古生物学家测量了肱部和股骨的周长。这些是支撑它体重的化石。
