The Sacrum is a section of fused vertebra that give the hip stability. The bone bar on the side is where the femur attached. Even though dinosaurs walked upright like mammals, they did not have ball & socket joints like we do. This specimen still had recognizable tendons. A Hadrosaur had a stiff back and tail because of these tendons. |
