Although it had a small brain and skull, Australopithecus sediba shows some human-like features in its reconstructed pelvis. The fossil record of the hominin pelvis reflects important evolutionary changes in locomotion and parturition. The partial pelves of two individuals of Australopithecus sediba were reconstructed from previously reported finds and new material. These remains share some features with australopiths, such as large biacetabular diameter, small sacral and coxal joints, and long… 
Special Issue: Australopithecus sediba The Pelvis of Australopithecus sediba
A mosaic of australopith-like and Homo-like morphology in the pelvis of Au.
Reconstructing birth in Australopithecus sediba
Evidence is found to support the hypothesis that the pelvic morphology of Australopithecus sediba is a result of locomotor, rather than strictly obstetric constraints, and to reconstruct the birth process in this early hominin.
Australopithecus sediba The Shoulder , Arm , and Forearm of Australopithecus sediba
T upper limbs are well represented in the Malapa hominins, revealing a shoulder, arm, and forearm in Au.
Mosaic Morphology in the Thorax of Australopithecus sediba
The ribs of Australopithecus sediba exhibit a mediolaterally narrow, ape-like upper thoracic shape, which is unlike the broad upper thorax of Homo that has been related to the locomotor pattern of endurance walking and running.
New fossils of Australopithecus sediba reveal a nearly complete lower back.
Three-dimensional geometric morphometric analyses show that Malapa Hominin 2's nearly complete middle lumbar vertebra is human-like in overall shape but its vertebral body is somewhat intermediate in shape between modern humans and great apes, indicating powerful trunk musculature.
The Vertebral Column of Australopithecus sediba
Two partial vertebral columns of Australopithecus sediba grant insight into aspects of early hominin spinal mobility, lumbar curvature, vertebral formula, and transitional vertebra position. Au.

New fossils of Australopithecus sediba reveal a nearly complete lower back
3D GM analyses show that MH2’s nearly complete middle lumbar vertebra is human-like in shape but bears large, cranially-directed transverse processes, implying powerful trunk musculature, and interpret this combination of features to indicate that A. sediba used its lower back in both human- like bipedalism and ape-like arboreal positional behaviors.

A complete human pelvis from the Middle Pleistocene of Spain
The Middle Pleistocene site of Sima de los Huesos in Sierra de Atapuerca, Spain, has yielded around 2,500 fossils from at least 33different hominid individuals, one of which is probably the primitive condition from which modern humans departed.
The Foot and Ankle of Australopithecus sediba
Observations suggest, if present models of foot function are correct, that Au.
The locomotor anatomy of Australopithecus afarensis.
It is demonstrated that A. afarensis possessed anatomic characteristics that indicate a significant adaptation for movement in the trees, and it is speculated that earlier representatives of the A.Afarensis lineage will present not a combination of arboreal and bipedal traits, but rather the anatomy of a generalized ape.
Effects of size and locomotor adaptations on the hominid pelvis: evaluation of australopithecine bipedality with a new multivariate method.
The pelvic morphology of A. africanus, as integrated with the articular pelvic-femoral link, appears to be biometrically equivalent to that of humans.

The results lend credence to the hypothesis that no single heterochronic process accounts for all human evolutionary change; rather this reflects a combination of relative changes in growth rhythm and duration, including other perturbations, such as the appearance of new morphological features.
An early Australopithecus afarensis postcranium from Woranso-Mille, Ethiopia
A large-bodied specimen is described that is well within the range of living Homo and substantially antedates A.L. 288–1, establishing that bipedality in Australopithecus was highly evolved and that thoracic form differed substantially from that of either extant African ape.
Australopithecus sediba Hand Demonstrates Mosaic Evolution of Locomotor and Manipulative Abilities
The hand of Australopithecus sediba, a rare example in the hominid fossil record, shows short fingers and a long thumb consistent with improved precision gripping while retaining strength for climbing, suggesting at least two distinct hand morphotypes around the Plio-Pleistocene transition.
Multivariate analysis of early hominid pelvic bones.
Multivariate analyses of the acetabular and iliac parts of fossil hominid and extant hominoid pelvic bones show that (1) the best preserved fossil from Swartkrans (SK 3155) is more similar to the
Australopithecus sediba: A New Species of Homo-Like Australopith from South Africa
Combined craniodental and postcranial evidence demonstrates that this new species of Australopithecus shares more derived features with early Homo than any other australopith species and thus might help reveal the ancestor of that genus.
