The latest research found that fossils of dinosaur leg bones have a certain degree of curvature, which means that dinosaurs are actually not as heavy as people think  When calculating animal weight based on the assumption that its leg bones are cylindrical, the calculation result will be more than the actual weight  1 42 times higher
The heavier the dinosaur's body, the thicker its leg bones
 Scientists therefore believe that the previous calculation method overestimated the maximum body weight that a dinosaur's legs could bear
