Australopithecine pelvis reconstructions provide insight into their mode of bipedal locomotion. There has been some variation in the reconstruction of the sacroilliac joint leading to different interpretations of the degree of bipedalism. Berge and Goularas define the major shared characteristics between australopithecines and humans as including a rotational fetal delivery pattern, a similar subpubic angle, and a similar short pubic symphysis (2010). These three similarities provide evidence for an upright posture that is skeletally supported to allow for a more humanlike stance and gait.
