Biomechanical reconstructions and selective advantages of neck poses and feeding strategies of Sauropods with the example of Mamenchisaurus youngi.

A very long neck is a characteristic feature of most sauropod dinosaurs. In the genus Mamenchisaurus, neck length is extreme, greater than 40 percent of total body length. However, the posture, utilization, and selective advantage of very long necks in sauropods are still controversial.
