Heaviest Dinosaur Discovered
發現最大恐龍化石
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.
阿根廷古生物學家認為他們發現了世界上最大的恐龍化石。他們相信這些化石屬于“無畏龍”，它是一種生活在大約9500年前的長頸食草類恐龍。科學家預計，這種恐龍大約有14個大象重。為了對它的身形進行估算，古生物學家測量了肱部和股骨的周長。這些是支撐它體重的化石。
